Astronomy (from Greek: αστρονομία) is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth’s atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.
Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and Maya performed methodical observations of the night sky. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astronomy is now often considered to be synonymous with astrophysics.
During the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, which is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results and observations being used to confirm theoretical results.
Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena. Amateur astronomers have made and contributed to many important astronomical discoveries, such as finding new comets.

B & Q Consumer Advocate Decoration Teach You Four Strokes Clear Anti-deception – The Decoration,
Recognition Decoration Quote transmission of the disease has merit
Buy a house is a happy thing, but a reference to buy a house after the renovation, who have experienced it they are moaning and do not chatter. Not only was the saddle before the horse in person after the governor array, tired of you fade a skin, when the quote is a fitting constant changes, the last is nobody knows for sure, much more than before the renovation budget. Now is the “gold 9 silver 10” discount shopping season, home improvement market is heating up. In order for consumers to no longer fitting into the bottomless pit B & Q Promote “full transparency” of the fitting model, so you plainly consumption.

Amount of low-budget offer deliberative Miss Zhu was about the decoration of a house, but the large and small use to the more than 100 kinds of materials, each material has different brands and styles, as different materials, the corresponding prices vary accordingly. In order to make their own snacks decoration when the province, Miss Zhu decided to interior decoration companies.

Lap decorating company, Miss Zhu was found in the selected Decoration materials Similar circumstances, the final offer is a big difference decoration. According to industry experts said, some non-formal decoration companies will adopt a “low-budget, high settlement offer” means to attract customers. Therefore, the owners must figure out decoration companies offer, in the verification of the “quote Masachika” the good pass.

Therefore, the program identified the owner after the decoration, decoration company will submit its budget to the owners, the owners should pay attention to finalizing the price of the following questions, to avoid the trap of their set: First, the construction budget project is consistent with the design; Second, the practice and the main materials technology brand, specifications are clearly defined; Third, water, electricity installation Project , The design meets the requirements, quantities are clear, the total price are clear; fourth unit construction project is reasonable; 5 of the total cost is beyond the investment plan.

Experts advise, decorated the company’s gross profit margin of 10% -30% discounted rate if more than this limit, the decoration company definitely in play “trick.” Consumers before signing the contract price of certain materials carefully to be considered clear enough, the best supplements marked “total no more than 10% of the budget offer.”

Beware of “additional” quote
In understanding some of the decoration market consumption “black hole”, the Miss Zhu chosen a more well-known interior design company responsible for their own home renovation. However, since the process is constantly being asked to change the previous design, the designer persuaded Miss Zhu repeated increase in renovation projects, do not need to do with a cabinet where the cabinet, no need to cook the ceiling where we seek lap ceiling. Complete renovation of a settlement, but also exceeded the budget.

Experience such as Miss Zhu, who had a lot of decoration have experienced. It is reported that, due to intense market competition, some decoration at the company in order to survive means to deliberately offer down, and then in the construction process require consumers to “additional” engineering models, this practice of intentionally deceiving consumers, often figuratively called “Fishing”, for example, some decoration companies for the budget, intends to toilet water, basement walls and other projects dealing with omitted, making it the company offer lower than other decoration. Some quick success of the decoration above the big issue in the design, or even to consumers under the “set”, deliberately misleading.

“Clean contracting” Let the consumer transparency
To make the decoration more transparent, B & Q launched a “clean contracting” mode. B & Q Decoration Centre’s “clean contracting” model of material costs and construction costs of buying separate purchase. By the consumers to buy their own designers, accompanied by a variety of materials, but materials prices supermarket marked price.

Decorating centers also offer full open, full and transparent. All labor costs are based on industry standards recommended by the scope of works in accordance with the actual amount of calculation. Management fee line decorated with the minimum standard of 5% regulation, tax collection according to the provisions of national unity. Project settlement, labor, materials in real settlement, Duotuishaobu, if there are well-decorated after the end of the remaining material can be returned by the original price.

B & Q will give each customer a card, all of the capital spending through the card through the system to a consumption of each track and checks to ensure the safety of funds. In the construction and acceptance of, the B & Q Decoration Centre is all set up for each client a complete file, including the customer’s budget, contracts, materials, engineering, quality supervision, the entire system by BSI British high quality supervision system recognition, one-time adoption of ISO9001: 2000 quality management certification indefinitely. The quality tracking and inspection system are very satisfactory.

The colorful harvest

The colorful harvest

Die Äpfel (Malus) bilden eine Pflanzengattung der Kernobstgewächse (Pyrinae) aus der Familie der Rosengewächse (Rosaceae). Die Gattung umfasst etwa 42 bis 55 Arten laubwerfender Bäume und Sträucher aus Wäldern und Dickichten der nördlichen gemäßigten Zone in Europa, Asien und Nordamerika, aus denen auch eine große Anzahl an oft schwer unterscheidbaren Hybriden hervorgegangen ist.

Die weltweit mit Abstand bekannteste und wirtschaftlich sehr bedeutende Art ist der Kulturapfel (Malus domestica). Daneben werden manche aus Ostasien stammende Arten mit nur etwa kirschgroßen Früchten, wie etwa der Japanische Apfel (Malus floribunda), der Kirschapfel (Malus baccata) und Malus ×zumi in gemäßigten Klimagebieten als Ziersträucher und -bäume angepflanzt. Nicht zu verwechseln mit den Äpfeln sind die nicht näher verwandten Granatäpfel (Punica granatum).
Das Wort Apfel wird auf die urindogermanische Form *h₂ébōl zurückgeführt, die nur Fortsetzungen im westlichen indogermanischen Sprachgebiet (Germanisch, Keltisch, Baltisch und Slawisch) hat und dort in allen Formen den Apfel bezeichnet. In der Forschung herrscht Uneinigkeit darüber, wie die Form genau anzusetzen ist und ob es sich um das urindogermanische Apfelwort handelt oder eine Entlehnung aus einer anderen Sprache. Aus der Akkusativform urindogermanisch *h₂ébl-ṃ > urgermanisch *ablun entwickelt sich das urgermanisches Apfelwort *ablus, aus dem (mit weiterer grammatikalischer Umgestaltung) althochdeutsch apful > Apfel (Mehrzahl epfili > Äpfel), altenglisch æppel > apple, isländisch epli hervorgehen.
Habitus und Belaubung
Die Arten der Gattung Äpfel (Malus) sind sommergrüne Bäume oder Sträucher. Sie sind meist unbewehrt. Die wechselständig angeordneten Laubblätter sind gestielt. Die einfache Blattspreite ist oval bis eiförmig oder elliptisch. Die Blattränder sind meist gesägt, selten glatt und manchmal gelappt. Einige Arten bzw. Sorten werden wegen ihres purpurnen Laubes im Herbst geschätzt. Nebenblätter sind vorhanden, verwelken aber oft früh.

Blütenstände und Blüten
Die gestielten Blüten der Apfelbäume stehen einzeln oder in doldigen schirmrispigen Blütenständen. Die fünfzähligen, zwittrigen, radiärsymmetrischen Blüten sind meist flach becherförmig und weisen meist einen Durchmesser von 2 bis 5 cm auf. Häufig duften die Blüten. Die Blütenachse ist krugförmig. Die fünf grünen Kelchblätter sind auch noch an den Früchten erhalten. Die fünf freien Kronblätter sind weiß, rosa oder rot. In jeder Blüte sind viele (15 bis 50) Staubblätter vorhanden, mit weißen Staubfäden und gelben Staubbeuteln. Aus drei bis fünf Fruchtblättern besteht der unterständige Fruchtknoten. Die drei bis fünf Griffel sind nur an ihrer Basis verwachsen. Bei einigen Züchtungen sind die Blüten, durch Umwandlung der Staubblätter in kronblattähnliche Blütenblätter, halbgefüllt oder gefüllt.
Gemeinhin bekannt sind die mehr oder minder rundlichen, essbaren Früchte. Bei einigen Arten sind sie roh ungenießbar. Das fleischige Gewebe, das normalerweise als Frucht bezeichnet wird, entsteht nicht aus dem Fruchtknoten, sondern aus der Blütenachse; der Biologe spricht daher von Scheinfrüchten. Genauer ist die Apfelfrucht eine Sonderform der Sammelbalgfrucht. Ein Balg besteht aus einem Fruchtblatt, das mit sich selbst verwächst. Innerhalb des Fruchtfleisches entsteht aus dem balgähnlichen Fruchtblatt ein pergamentartiges Gehäuse. Im Fruchtfleisch selbst sind höchstens noch vereinzelt Steinzellennester enthalten. Die Samen sind braun oder schwarz; sie enthalten geringe Mengen an giftigen Cyaniden.
Die Gattung Malus gehört zur Subtribus Pyrinae der Tribus Pyreae in der Unterfamilie Spiraeoideae innerhalb der Familie Rosaceae. Der Gattungsname Malus wurde 1754 durch Philip Miller in Gard. Dict. Abr., 4. Auflage, S. 835, erstveröffentlicht. Synonyme für Malus Mill. sind Docyniopsis (C.K.Schneid.) Koidz., Eriolobus (DC.) M.Roem.[2]

Es gibt etwa 42 bis 55 Malus-Arten; hier eine Auflistung mit Heimatangaben. Zu den bekannten Sorten der fruchtliefernden Apfelbäume siehe Kulturapfel und Apfelsorten.

Malus (/ˈmeɪləs/[3] or /ˈmæləs/), apple, is a genus of about 30–55 species[4] of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple (M. domestica). The other species are generally known as crabapples, crab apples, crabs, or wild apples.

The genus is native to the temperate zone of the Northern Hemisphere.
Apple trees are typically 4–12 m (13–39 ft) tall at maturity, with a dense, twiggy crown. The leaves are 3–10 cm (1.2–3.9 in) long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree days (varying greatly according to subspecies and cultivar).

Apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); all are self-sterile, and (with the exception of a few specially developed cultivars) self-pollination is impossible, making pollinating insects essential. Several Malus species, including domestic apples, hybridize freely.[6] They are used as food plants by the larvae of a large number of Lepidoptera species; see list of Lepidoptera that feed on Malus.

The fruit is a globose pome, varying in size from 1–4 cm (0.39–1.57 in) diameter in most of the wild species, to 6 cm (2.4 in) in M. sylvestris sieversii, 8 cm (3.1 in) in M. domestica, and even larger in certain cultivated orchard apples. The centre of the fruit contains five carpels arranged star-like, each containing one or two seeds.

For the Malus domestica cultivars, the cultivated apples, see Apple.

Crabapples are popular as compact ornamental trees, providing blossom in Spring and colourful fruit in Autumn. The fruits often persist throughout Winter. Numerous hybrid cultivars have been selected, of which ‘Evereste'[7] and ‘Red Sentinel'[8] have gained The Royal Horticultural Society’s Award of Garden Merit.

Other varieties are dealt with under their species names.

Some crabapples are used as rootstocks for domestic apples to add beneficial characteristics.[9] For example, varieties of Baccata, also called Siberian crab, rootstock is used to give additional cold hardiness to the combined plant for orchards in cold northern areas.[10]

They are also used as pollinizers in apple orchards. Varieties of crabapple are selected to bloom contemporaneously with the apple variety in an orchard planting, and the crabs are planted every sixth or seventh tree, or limbs of a crab tree are grafted onto some of the apple trees. In emergencies, a bucket or drum bouquet of crabapple flowering branches are placed near the beehives as orchard pollenizers. See also Fruit tree pollination. Because of the plentiful blossoms and small fruit, crabapples are popular for use in bonsai culture.

Crabapple fruit is not an important crop in most areas, being extremely sour and (in some species) woody, and is rarely eaten raw for this reason. In some southeast Asian cultures they are valued as a sour condiment, sometimes eaten with salt and chilli pepper, or shrimp paste.

Some crabapples varieties are an exception to the reputation of being sour, and can be very sweet, such as the ‘Chestnut’ cultivar.[11]

Crabapples are an excellent source of pectin, and their juice can be made into a ruby-coloured preserve with a full, spicy flavour.[12] A small percentage of crabapples in cider makes a more interesting flavour.[13] As Old English Wergulu, the crab apple is one of the nine plants invoked in the pagan Anglo-Saxon Nine Herbs Charm, recorded in the 10th century.

Apple wood gives off a pleasant scent when burned, and smoke from an apple wood fire gives an excellent flavour to smoked foods.[14] It is easier to cut when green; dry apple wood is exceedingly difficult to carve by hand.[14] It is a good wood for cooking fires because it burns hot and slow, without producing much flame.[14]

Crabapple has been listed as one of the 38 plants that are used to prepare Bach flower remedies,[15] a kind of alternative medicine promoted for its effect on health. However according to Cancer Research UK, "there is no scientific evidence to prove that flower remedies can control, cure or prevent any type of disease, including cancer".

Apfelsaft (in der Schweiz und Österreich auch Süßmost) ist ein Fruchtsaft, der durch Pressung von Äpfeln gewonnen wird. Aus 1,5 kg Äpfeln kann ca. 1 Liter Apfelsaft gewonnen werden. Im großen Maßstab geschieht dies in Keltereien. Als Apfelschorle wird er mit Mineralwasser verdünnt getrunken. 2013 betrug in Deutschland der Pro-Kopf-Verbrauch an Apfelsaft 8,4 Liter und an Apfelsaftschorle 8,5 Liter.
Nach dem Pressen ist der Apfelsaft immer naturtrüb, d. h. fruchtfleischhaltig. Zentrifugiert und gefiltert erhält man den klaren Apfelsaft. Beide Varianten – naturtrüb und klar – werden durch Pasteurisation haltbar gemacht. Dabei wird der Saft kurz auf ca. 85 °C erhitzt, um Mikroorganismen abzutöten und die Gärung zu verhindern. Da der naturtrübe Apfelsaft nicht gefiltert wurde, befinden sich in ihm noch die Schwebstoffe. Sie lassen den Saft undurchsichtig erscheinen. Da sie schwerer sind als Wasser, setzen sie sich am Boden ab und sollten vor dem Trinken aufgeschüttelt werden. Aufgrund der in den Schwebstoffen enthaltenen Antioxidantien – es handelt sich hauptsächlich um Polyphenole – enthält naturtrüber Apfelsaft mehr sekundäre Pflanzenstoffe als gefilterter Saft.[2] In Tierversuchen entwickelten Mäuse und Ratten, denen Apfelsaft verabreicht wurde, bis zu 50 % weniger Tumoren, als die Vergleichsgruppe ohne die Apfelsaftgaben.[3][4] Der trübe Apfelsaft war in diesen Versuchen wirksamer als der klare.[5] Vermutlich sind hier die Procyanidine, die in trübem Apfelsaft in hoher Konzentration enthalten sind, die Ursache.[6] Darüber hinaus schmeckt der naturtrübe Apfelsaft meist auch natürlicher und kräftiger als der schwebstofffreie klare Saft. Sortenreine Apfelsäfte, die nur aus einer Apfelsorte gewonnen werden, erweitern die Angebotspalette an Apfelsaft mit einer hohen geschmacklichen Vielfalt.

Zur Herstellung von klarem Apfelsaft wird überwiegend Apfelsaftkonzentrat verwendet. Apfelsaftkonzentrat erhält man durch Entzug von Wasser und Abtrennen von Aromen. Dadurch reduziert sich das Volumen auf ca. ein Sechstel, sodass die Lagerung und der Transport günstiger werden. Durch Hinzufügen von speziell aufbereitetem Trinkwasser und den getrennt gelagerten Aromen erreicht man ein zum ursprünglichen Ausgangsprodukt gleichartiges Produkt. In der Fachsprache nennt sich das rekonstituieren. Die Verarbeitung von Apfelsaftkonzentrat bringt zusätzlich den Vorteil, durch Verschneiden (Mischen) unterschiedlich ausgeprägter Apfelsaftkonzentrate (süße/saure) einen gleichbleibenden Geschmack zu erreichen. Ansonsten würden je nach Apfelsorte und/oder Anbaugebiet unterschiedliche Geschmacksrichtungen im Apfelsaft auftreten.

Die Verfahren des Wasserentzuges und der Rückverdünnung beeinträchtigen auf modernen Konzentratanlagen den Geschmack und den Vitamingehalt kaum. In der deutschen Fruchtsaftverordnung (FrSaftV 2004) und in den Fruchtsaftrichtlinien der EU muss der rückverdünnte Saft gleichartige organoleptische und analytische Eigenschaften aufweisen wie ein nicht aus Konzentrat hergestellter Saft (Direktsaft) aus frischen Früchten derselben Art. Die analytische Gleichartigkeit der nicht flüchtigen Hauptinhaltsstoffe kann über Grad Brix, Zuckerspektrum, Aminosäurespektrum und Mineralstoffe beurteilt werden. Kennzahlen zur Beurteilung sind im AIJN Code of Practice[7] beschrieben. Für die Beurteilung der analytischen Gleichartigkeit des Apfelsaftaromas wird ein Aromaindex Apfel ermittelt.

Apfelsaft dient auch als Vorprodukt für Apfelwein (Cidre, Viez, Most), Apfelkraut und Apfelessig; darüber hinaus wird er auch zur Herstellung von Spirituosen, wie Obstbrand, Apfelkorn oder des bekannten Calvados verwendet.

In der Region um Frankfurt am Main wird der frische, trübe, nicht pasteurisierte Apfelsaft „Süßer“ genannt und zur Erntezeit genossen.

Streuobstwiesen sind eine traditionelle Form des Apfelanbaus. Deutsche Fruchtsafthersteller setzen sich aus Naturschutz- und Qualitätsgründen für dessen Erhaltung und Förderung ein. In Deutschland wird der Apfel bei der Fruchtsaftherstellung zu 100 Prozent verarbeitet. Etwa 75 Prozent ist die Saftausbeute, 25 Prozent bleiben als ausgepresste Maische mit Schalen und Kernen übrig – das ist der so genannte Trester. Er geht etwa zur Hälfte in die Herstellung von Apfelpektin, das z. B. als pflanzliches Geliermittel verwendet werden kann. Die andere Hälfte geht in die Tierfütterung oder Energiegewinnung.
Apple juice is a fruit juice made by the maceration and pressing of apples. The resulting expelled juice may be further treated by enzymatic and centrifugal clarification to remove the starch and pectin, which holds fine particulate in suspension, and then pasteurized for packaging in glass, metal or aseptic processing system containers, or further treated by dehydration processes to a concentrate.

Due to the complex and costly equipment required to extract and clarify juice from apples in large volume, apple juice is normally commercially produced. In the United States, unfiltered fresh apple juice is made by smaller operations in areas of high apple production, in the form of unclarified apple cider. Apple juice is one of the most common fruit juices in the world, with world production led by China, Poland, the United States, and Germany.

Vitamin C is sometimes added by fortification, because content is variable,[2] and much of that is lost in processing.[citation needed] Vitamin C also helps to prevent oxidation of the product.[3] Other vitamin concentrations are low, but apple juice does contain various mineral nutrients, including boron, which may promote healthy bones.[4] Apple juice has a significant concentration of natural phenols of low molecular weight (including chlorogenic acid, flavan-3-ols, and flavonols) and procyanidins[5] that may protect from diseases associated with aging due to the antioxidant effects which help reduce the likelihood of developing cancer and Alzheimer’s disease.[6] Research suggests that apple juice increases acetylcholine in the brain, possibly resulting in improved memory.[7] Despite having some health benefits, apple juice is high in sugar. It has 28 g carbohydrates (24 g sugars) per 230 g (8 ounces). This results in 130 calories per 230 g (8 ounces) – protein and fat are not significant. Also like most fruit juice, apple juice contains a similar amount of sugar as the raw fruit, but lacks the fiber content.
While apple juice generally refers to the filtered, pasteurised product of apple pressing, an unfiltered and sometimes unpasteurised product commonly known as apple cider in the United States and parts of Canada may be packaged and sold as apple juice. In the U.S., the opposite is often seen; filtered and clarified juice (including carbonated varieties) may be sold as "apple cider", thus there is an unclear distinction between filtered apple juice and natural apple cider.[8] In other places such as New Zealand, Australia and the United Kingdom, apple cider is an alcoholic beverage. The alcoholic beverage referred to as cider in these areas is usually referred to as hard cider in the United States.

Recycling is a process to change (waste) materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production.[1][2] Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse and Recycle" waste hierarchy.

There are some ISO standards related to recycling such as ISO 15270:2008 for plastics waste and ISO 14001:2004 for environmental management control of recycling practice.

Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. Although similar in effect, the composting or other reuse of biodegradable waste—such as food or garden waste—is considered recycling.[2] Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing.

In the strictest sense, recycling of a material would produce a fresh supply of the same material—for example, used office paper would be converted into new office paper, or used foamed polystyrene into new polystyrene. However, this is often difficult or too expensive (compared with producing the same product from raw materials or other sources), so "recycling" of many products or materials involves their reuse in producing different materials (e.g., paperboard) instead. Another form of recycling is the salvage of certain materials from complex products, either due to their intrinsic value (e.g., lead from car batteries, or gold from computer components), or due to their hazardous nature (e.g., removal and reuse of mercury from various items). Critics dispute the net economic and environmental benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from confirmation bias. Specifically, critics argue that the costs and energy used in collection and transportation detract from (and outweigh) the costs and energy saved in the production process; also that the jobs produced by the recycling industry can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production; and that materials such as paper pulp can only be recycled a few times before material degradation prevents further recycling. Proponents of recycling dispute each of these claims, and the validity of arguments from both sides has led to enduring controversy.
Recycling has been a common practice for most of human history, with recorded advocates as far back as Plato in 400 BC. During periods when resources were scarce, archaeological studies of ancient waste dumps show less household waste (such as ash, broken tools and pottery)—implying more waste was being recycled in the absence of new material.

In pre-industrial times, there is evidence of scrap bronze and other metals being collected in Europe and melted down for perpetual reuse.[4] In Britain dust and ash from wood and coal fires was collected by ‘dustmen’ and downcycled as a base material used in brick making. The main driver for these types of recycling was the economic advantage of obtaining recycled feedstock instead of acquiring virgin material, as well as a lack of public waste removal in ever more densely populated areas.[3] In 1813, Benjamin Law developed the process of turning rags into ‘shoddy’ and ‘mungo’ wool in Batley, Yorkshire. This material combined recycled fibres with virgin wool. The West Yorkshire shoddy industry in towns such as Batley and Dewsbury, lasted from the early 19th century to at least 1914.

Industrialization spurred demand for affordable materials; aside from rags, ferrous scrap metals were coveted as they were cheaper to acquire than was virgin ore. Railroads both purchased and sold scrap metal in the 19th century, and the growing steel and automobile industries purchased scrap in the early 20th century. Many secondary goods were collected, processed, and sold by peddlers who combed dumps, city streets, and went door to door looking for discarded machinery, pots, pans, and other sources of metal. By World War I, thousands of such peddlers roamed the streets of American cities, taking advantage of market forces to recycle post-consumer materials back into industrial production.[5]

Beverage bottles were recycled with a refundable deposit at some drink manufacturers in Great Britain and Ireland around 1800, notably Schweppes.[6] An official recycling system with refundable deposits was established in Sweden for bottles in 1884 and aluminium beverage cans in 1982, by law, leading to a recycling rate for beverage containers of 84–99 percent depending on type, and average use of a glass bottle is over 20 refills.

Wartime
Recycling was a highlight throughout World War II. During the war, financial constraints and significant material shortages due to war efforts made it necessary for countries to reuse goods and recycle materials.[7] It was these resource shortages caused by the world wars, and other such world-changing occurrences that greatly encouraged recycling.[8] The struggles of war claimed much of the material resources available, leaving little for the civilian population.[7] It became necessary for most homes to recycle their waste, as recycling offered an extra source of materials allowing people to make the most of what was available to them. Recycling materials that were used in the household, meant more resources were available to support war efforts. This in turn meant a better chance of victory at war.[7] Massive government promotion campaigns were carried out in World War II in every country involved in the war, urging citizens to donate metals and conserve fibre, as a matter of significant patriotic importance. There was patriotism in recycling.

Post-war
A considerable investment in recycling occurred in the 1970s, due to rising energy costs.[citation needed] Recycling aluminium uses only 5% of the energy required by virgin production; glass, paper and metals have less dramatic but very significant energy savings when recycled feedstock is used.

As of 2014, the European Union has about 50% of world share of the waste and recycling industries, with over 60,000 companies employing 500,000 persons, with a turnover of €24 billion.[10] Countries have to reach recycling rates of at least 50%, while the lead countries are around 65% and the EU average is 39% as of 2013.
For a recycling program to work, having a large, stable supply of recyclable material is crucial. Three legislative options have been used to create such a supply: mandatory recycling collection, container deposit legislation, and refuse bans. Mandatory collection laws set recycling targets for cities to aim for, usually in the form that a certain percentage of a material must be diverted from the city’s waste stream by a target date. The city is then responsible for working to meet this target.[2]

Container deposit legislation involves offering a refund for the return of certain containers, typically glass, plastic, and metal. When a product in such a container is purchased, a small surcharge is added to the price. This surcharge can be reclaimed by the consumer if the container is returned to a collection point. These programs have been very successful, often resulting in an 80 percent recycling rate. Despite such good results, the shift in collection costs from local government to industry and consumers has created strong opposition to the creation of such programs in some areas.[2]

A third method of increase supply of recyclates is to ban the disposal of certain materials as waste, often including used oil, old batteries, tires and garden waste. One aim of this method is to create a viable economy for proper disposal of banned products. Care must be taken that enough of these recycling services exist, or such bans simply lead to increased illegal dumping.[2]

Government-mandated demand
Legislation has also been used to increase and maintain a demand for recycled materials. Four methods of such legislation exist: minimum recycled content mandates, utilization rates, procurement policies, recycled product labeling.

Both minimum recycled content mandates and utilization rates increase demand directly by forcing manufacturers to include recycling in their operations. Content mandates specify that a certain percentage of a new product must consist of recycled material. Utilization rates are a more flexible option: industries are permitted to meet the recycling targets at any point of their operation or even contract recycling out in exchange for [trade]able credits. Opponents to both of these methods point to the large increase in reporting requirements they impose, and claim that they rob industry of necessary flexibility.

Governments have used their own purchasing power to increase recycling demand through what are called "procurement policies." These policies are either "set-asides," which earmark a certain amount of spending solely towards recycled products, or "price preference" programs which provide a larger budget when recycled items are purchased. Additional regulations can target specific cases: in the United States, for example, the Environmental Protection Agency mandates the purchase of oil, paper, tires and building insulation from recycled or re-refined sources whenever possible.[2]

The final government regulation towards increased demand is recycled product labeling. When producers are required to label their packaging with amount of recycled material in the product (including the packaging), consumers are better able to make educated choices. Consumers with sufficient buying power can then choose more environmentally conscious options, prompt producers to increase the amount of recycled material in their products, and indirectly increase demand. Standardized recycling labeling can also have a positive effect on supply of recyclates if the labeling includes information on how and where the product can be recycled.[2]

Recyclates
Recyclate is a raw material that is sent to, and processed in a waste recycling plant or materials recovery facility which will be used to form new products.[13] The material is collected in various methods and delivered to a facility where it undergoes re-manufacturing so that it can used in the production of new materials or products. For example, plastic bottles that are collected can be re-used and made into plastic pellets, a new product.[14]

Quality of recyclate
The quality of recyclates is recognized as one of the principal challenges that needs to be addressed for the success of a long term vision of a green economy and achieving zero waste. Recyclate quality is generally referring to how much of the raw material is made up of target material compared to the amount of non-target material and other non- recyclable material.[15] Only target material is likely to be recycled, so a higher amount of non-target and non-recyclable material will reduce the quantity of recycling product.[15] A high proportion of non-target and non-recyclable material can make it more difficult for re-processors to achieve ‘high-quality’ recycling. If the recyclate is of poor quality, it is more likely to end up being down-cycled or, in more extreme cases, sent to other recovery options or landfill.[15] For example, to facilitate the re-manufacturing of clear glass products there are tight restrictions for colored glass going into the re-melt process.

The quality of recyclate not only supports high quality recycling, it can deliver significant environmental benefits by reducing, reusing, and keeping products out of landfills.[15] High quality recycling can help support growth in the economy by maximizing the economic value of the waste material collected.[15] Higher income levels from the sale of quality recyclates can return value which can be significant to local governments, households and businesses.[15] Pursuing high quality recycling can also provide consumer and business confidence in the waste and resource management sector and may encourage investment in that sector.

There are many actions along the recycling supply chain that can influence and affect the material quality of recyclate.[16] It begins with the waste producers who place non-target and non-recyclable wastes in recycling collection. This can affect the quality of final recyclate streams or require further efforts to discard those materials at later stages in the recycling process.[16] The different collection systems can result in different levels of contamination. Depending on which materials are collected together, extra effort is required to sort this material back into separate streams and can significantly reduce the quality of the final product.[16] Transportation and the compaction of materials can make it more difficult to separate material back into separate waste streams. Sorting facilities are not one hundred per cent effective in separating materials, despite improvements in technology and quality recyclate which can see a loss in recyclate quality.[16] The storage of materials outside where the product can become wet can cause problems for re-processors. Reprocessing facilities may require further sorting steps to further reduce the amount of non-target and non-recyclable material.[16] Each action along the recycling path plays a part in the quality of recyclate.

Quality recyclate action plan (Scotland)
The Recyclate Quality Action Plan of Scotland sets out a number of proposed actions that the Scottish Government would like to take forward in order to drive up the quality of the materials being collected for recycling and sorted at materials recovery facilities before being exported or sold on to the reprocessing market.[16]

The plan’s objectives are to:

Drive up the quality of recyclate.
Deliver greater transparency around the quality of recyclate.
Provide help to those contracting with materials recycling facilities to identify what is required of them
Ensure compliance with the Waste (Scotland) regulations 2012.
Stimulate a household market for quality recyclate.
Address and reduce issues surrounding the Waste Shipment Regulations.
The plan focuses on three key areas, with fourteen actions which were identified to increase the quality of materials collected, sorted and presented to the processing market in Scotland.[17]

The three areas of focus are:

Collection systems and input contamination
Sorting facilities – material sampling and transparency
Material quality benchmarking and standards
Recycling consumer waste
A number of different systems have been implemented to collect recyclates from the general waste stream. These systems lie along the spectrum of trade-off between public convenience and government ease and expense. The three main categories of collection are "drop-off centres," "buy-back centres," and "curbside collection".

Drop-off centres
Drop-off centres require the waste producer to carry the recyclates to a central location, either an installed or mobile collection station or the reprocessing plant itself. They are the easiest type of collection to establish, but suffer from low and unpredictable throughput.

Buy-back centres
Buy-back centres differ in that the cleaned recyclates are purchased, thus providing a clear incentive for use and creating a stable supply. The post-processed material can then be sold on, hopefully creating a profit. Unfortunately, government subsidies are necessary to make buy-back centres a viable enterprise, as according to the United States’ National Waste & Recycling Association, it costs on average US$50 to process a ton of material, which can only be resold for US$30.[2]

Curbside collection
Main article: Curbside collection
Curbside collection encompasses many subtly different systems, which differ mostly on where in the process the recyclates are sorted and cleaned. The main categories are mixed waste collection, commingled recyclables and source separation.[2] A waste collection vehicle generally picks up the waste.
At one end of the spectrum is mixed waste collection, in which all recyclates are collected mixed in with the rest of the waste, and the desired material is then sorted out and cleaned at a central sorting facility. This results in a large amount of recyclable waste, paper especially, being too soiled to reprocess, but has advantages as well: the city need not pay for a separate collection of recyclates and no public education is needed. Any changes to which materials are recyclable is easy to accommodate as all sorting happens in a central location.[2]

In a commingled or single-stream system, all recyclables for collection are mixed but kept separate from other waste. This greatly reduces the need for post-collection cleaning but does require public education on what materials are recyclable.[2][4]

Source separation is the other extreme, where each material is cleaned and sorted prior to collection. This method requires the least post-collection sorting and produces the purest recyclates, but incurs additional operating costs for collection of each separate material. An extensive public education program is also required, which must be successful if recyclate contamination is to be avoided.[2]

Source separation used to be the preferred method due to the high sorting costs incurred by commingled (mixed waste) collection. Advances in sorting technology (see sorting below), however, have lowered this overhead substantially—many areas which had developed source separation programs have since switched to comingled collection.[4]

Distributed Recycling
For some waste materials such as plastic, recent technical devices called recyclebots[18] enable a form of distributed recycling. Preliminary life-cycle analysis(LCA) indicates that such distributed recycling of HDPE to make filament of 3-D printers in rural regions is energetically favorable to either using virgin resin or conventional recycling processes because of reductions in transportation energy[19]

Sorting

Once commingled recyclates are collected and delivered to a central collection facility, the different types of materials must be sorted. This is done in a series of stages, many of which involve automated processes such that a truckload of material can be fully sorted in less than an hour.[4] Some plants can now sort the materials automatically, known as single-stream recycling. In plants a variety of materials are sorted such as paper, different types of plastics, glass, metals, food scraps, and most types of batteries.[20] A 30 percent increase in recycling rates has been seen in the areas where these plants exist.[21]

Initially, the commingled recyclates are removed from the collection vehicle and placed on a conveyor belt spread out in a single layer. Large pieces of corrugated fiberboard and plastic bags are removed by hand at this stage, as they can cause later machinery to jam.

Next, automated machinery separates the recyclates by weight, splitting lighter paper and plastic from heavier glass and metal. Cardboard is removed from the mixed paper, and the most common types of plastic, PET (#1) and HDPE (#2), are collected. This separation is usually done by hand, but has become automated in some sorting centers: a spectroscopic scanner is used to differentiate between different types of paper and plastic based on the absorbed wavelengths, and subsequently divert each material into the proper collection channel.[4]

Strong magnets are used to separate out ferrous metals, such as iron, steel, and tin-plated steel cans ("tin cans"). Nonferrous metals are ejected by magnetic eddy currents in which a rotating magnetic field induces an electric current around the aluminium cans, which in turn creates a magnetic eddy current inside the cans. This magnetic eddy current is repulsed by a large magnetic field, and the cans are ejected from the rest of the recyclate stream.[4]

Finally, glass must be sorted by hand on the basis of its color: brown, amber, green, or clear.[4]

This process of recycling as well as reusing the recycled material proves to be advantageous for many reasons as it reduces amount of waste sent to landfills, conserves natural resources, saves energy, reduces greenhouse gas emissions, and helps create new jobs. Recycled materials can also be converted into new products that can be consumed again such as paper, plastic, and glass.[22]

The City and County of San Francisco’s Department of the Environment offers one of the best recycling programs to support its city-wide goal of Zero Waste by 2020.[23] San Francisco’s refuse hauler, Recology, operates an effective recyclables sorting facility in San Francisco, which helped San Francisco reach a record-breaking diversion rate of 80%.[24]

Recycling industrial waste

Although many government programs are concentrated on recycling at home, a large portion of waste is generated by industry. The focus of many recycling programs done by industry is the cost-effectiveness of recycling. The ubiquitous nature of cardboard packaging makes cardboard a commonly recycled waste product by companies that deal heavily in packaged goods, like retail stores, warehouses, and distributors of goods. Other industries deal in niche or specialized products, depending on the nature of the waste materials that are present.

The glass, lumber, wood pulp, and paper manufacturers all deal directly in commonly recycled materials. However, old rubber tires may be collected and recycled by independent tire dealers for a profit.

Levels of metals recycling are generally low. In 2010, the International Resource Panel, hosted by the United Nations Environment Programme (UNEP) published reports on metal stocks that exist within society[25] and their recycling rates.[26] The Panel reported that the increase in the use of metals during the 20th and into the 21st century has led to a substantial shift in metal stocks from below ground to use in applications within society above ground. For example, the in-use stock of copper in the USA grew from 73 to 238 kg per capita between 1932 and 1999.

The report authors observed that, as metals are inherently recyclable, the metals stocks in society can serve as huge mines above ground (the term "urban mining" has been coined with this idea in mind[27]). However, they found that the recycling rates of many metals are very low. The report warned that the recycling rates of some rare metals used in applications such as mobile phones, battery packs for hybrid cars and fuel cells, are so low that unless future end-of-life recycling rates are dramatically stepped up these critical metals will become unavailable for use in modern technology.

The military recycles some metals. The U.S. Navy’s Ship Disposal Program uses ship breaking to reclaim the steel of old vessels. Ships may also be sunk to create an artificial reef. Uranium is a very dense metal that has qualities superior to lead and titanium for many military and industrial uses. The uranium left over from processing it into nuclear weapons and fuel for nuclear reactors is called depleted uranium, and it is used by all branches of the U.S. military use for armour-piercing shells and shielding.

The construction industry may recycle concrete and old road surface pavement, selling their waste materials for profit.

Some industries, like the renewable energy industry and solar photovoltaic technology in particular, are being proactive in setting up recycling policies even before there is considerable volume to their waste streams, anticipating future demand during their rapid growth.[28]

Recycling of plastics is more difficult, as most programs can’t reach the necessary level of quality. Recycling of PVC often results in downcycling of the material, which means only products of lower quality standard can be made with the recycled material. A new approach which allows an equal level of quality is the Vinyloop process. It was used after the London Olympics 2012 to fulfill the PVC Policy.[29]

e-Waste recycling
Main article: Computer recycling
E-waste is a growing problem, accounting for 20-50 million metric tons of global waste per year according to the EPA. Many recyclers do not recycle e-waste or do not do so responsibly. The e-Stewards certification was created to ensure recyclers are held to the highest standards for environmental responsibility and to give consumers an easy way to identify responsible recyclers. e-Cycle, LLC, was the first mobile recycling company to be e-Stewards certified.

Plastic recycling
Main article: Plastic recycling
Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products, sometimes completely different in form from their original state. For instance, this could mean melting down soft drink bottles and then casting them as plastic chairs and tables.[30]

Physical Recycling
Some plastics are remelted to form new plastic objects, for example PET water bottles can be converted into clothing grade polyester. A disadvantage of this type of recycling is that in each use and recycling cycle the molecular weight of the polymer can change further and the levels of unwanted substances in the plastic can increase.

Chemical Recycling
For some polymers it is possible to convert them back into monomers, for example PET can be treated with an alcohol and a catalyst to form a dialkyl terephthalate. The terephthalate diester can be used with ethylene glycol to form a new polyester polymer. Thus it is possible to make the pure polymer again.

Waste Plastic Pyrolysis to fuel oil
Another process involves the conversion of assorted polymers into petroleum by a much less precise thermal depolymerization process. Such a process would be able to accept almost any polymer or mix of polymers, including thermoset materials such as vulcanized rubber tires and the biopolymers in feathers and other agricultural waste. Like natural petroleum, the chemicals produced can be made into fuels as well as polymers. RESEM Technology[31] plant of this type exists in Carthage, Missouri, USA, using turkey waste as input material. Gasification is a similar process, but is not technically recycling since polymers are not likely to become the result. Plastic Pyrolysis can convert petroleum based waste streams such as plastics into quality fuels, carbons. Given below is the list of suitable plastic raw materials for pyrolysis:

Mixed plastic (HDPE, LDPE, PE, PP, Nylon, Teflon, PS, ABS, FRP etc.)
Mixed waste plastic from waste paper mill
Multi Layered Plastic
Recycling codes
Main article: Recycling codes
In order to meet recyclers’ needs while providing manufacturers a consistent, uniform system, a coding system is developed. The recycling code for plastics was introduced in 1988 by plastics industry through the Society of the Plastics Industry, Inc.[32] Because municipal recycling programs traditionally have targeted packaging—primarily bottles and containers—the resin coding system offered a means of identifying the resin content of bottles and containers commonly found in the residential waste stream.

Plastic products are printed with numbers 1–7 depending on the type of resin. Type 1 plastic, PET (or PETE): polyethylene terephthalate, is commonly found in soft drink and water bottles. Type 2, HDPE: high-density polyethylene is found in most hard plastics such as milk jugs, laundry detergent bottles, and some dishware. Type 3, PVC or V (vinyl), includes items like shampoo bottles, shower curtains, hoola hoops, credit cards, wire jacketing, medical equipment, siding, and piping. Type 4, called LDPE, or low-density polyethylene, is found in shopping bags, squeezable bottles, tote bags, clothing, furniture, and carpet. Type 5 is PP which stands for polypropylene and makes up syrup bottles, straws, Tupperware, and some automotive parts. Type 6 is PS: polystyrene and makes up meat trays, egg cartons, clamshell containers and compact disc cases. Type 7 includes all other plastics like bulletproof materials, 3- and 5-gallon water bottles, and sunglasses.[34] Types 1 and 2 are the most commonly recycled.

There is some debate over whether recycling is economically efficient. It is said[by whom?] that dumping 10,000 tons of waste in a landfill creates six jobs, while recycling 10,000 tons of waste can create over 36 jobs. However, the cost effectiveness of creating the additional jobs remains unproven. According to the U.S. Recycling Economic Informational Study, there are over 50,000 recycling establishments that have created over a million jobs in the US.[37] Two years after New York City declared that implementing recycling programs would be "a drain on the city," New York City leaders realized that an efficient recycling system could save the city over $20 million.[38] Municipalities often see fiscal benefits from implementing recycling programs, largely due to the reduced landfill costs.[39] A study conducted by the Technical University of Denmark according to the Economist found that in 83 percent of cases, recycling is the most efficient method to dispose of household waste.[4][9] However, a 2004 assessment by the Danish Environmental Assessment Institute concluded that incineration was the most effective method for disposing of drink containers, even aluminium ones.[40]

Fiscal efficiency is separate from economic efficiency. Economic analysis of recycling do not include what economists call externalities, which are unpriced costs and benefits that accrue to individuals outside of private transactions. Examples include: decreased air pollution and greenhouse gases from incineration, reduced hazardous waste leaching from landfills, reduced energy consumption, and reduced waste and resource consumption, which leads to a reduction in environmentally damaging mining and timber activity. About 4,000 minerals are known, of these only a few hundred minerals in the world are relatively common.[41] Known reserves of phosphorus will be exhausted within the next 100 years at current rates of usage.[42][43] Without mechanisms such as taxes or subsidies to internalize externalities, businesses will ignore them despite the costs imposed on society.[opinion] To make such nonfiscal benefits economically relevant, advocates have pushed for legislative action to increase the demand for recycled materials.[2] The United States Environmental Protection Agency (EPA) has concluded in favor of recycling, saying that recycling efforts reduced the country’s carbon emissions by a net 49 million metric tonnes in 2005.[4] In the United Kingdom, the Waste and Resources Action Programme stated that Great Britain’s recycling efforts reduce CO2 emissions by 10–15 million tonnes a year.[4] Recycling is more efficient in densely populated areas, as there are economies of scale involved.

Certain requirements must be met for recycling to be economically feasible and environmentally effective. These include an adequate source of recyclates, a system to extract those recyclates from the waste stream, a nearby factory capable of reprocessing the recyclates, and a potential demand for the recycled products. These last two requirements are often overlooked—without both an industrial market for production using the collected materials and a consumer market for the manufactured goods, recycling is incomplete and in fact only "collection".[2]

Many[who?] economists favor a moderate level of government intervention to provide recycling services. Economists of this mindset probably view product disposal as an externality of production and subsequently argue government is most capable of alleviating such a dilemma.

Trade in recyclates
Certain countries trade in unprocessed recyclates. Some have complained that the ultimate fate of recyclates sold to another country is unknown and they may end up in landfills instead of reprocessed. According to one report, in America, 50–80 percent of computers destined for recycling are actually not recycled.[44][45] There are reports of illegal-waste imports to China being dismantled and recycled solely for monetary gain, without consideration for workers’ health or environmental damage. Although the Chinese government has banned these practices, it has not been able to eradicate them.[46] In 2008, the prices of recyclable waste plummeted before rebounding in 2009. Cardboard averaged about £53/tonne from 2004–2008, dropped to £19/tonne, and then went up to £59/tonne in May 2009. PET plastic averaged about £156/tonne, dropped to £75/tonne and then moved up to £195/tonne in May 2009.[47] Certain regions have difficulty using or exporting as much of a material as they recycle. This problem is most prevalent with glass: both Britain and the U.S. import large quantities of wine bottled in green glass. Though much of this glass is sent to be recycled, outside the American Midwest there is not enough wine production to use all of the reprocessed material. The extra must be downcycled into building materials or re-inserted into the regular waste stream.[2][4]

Similarly, the northwestern United States has difficulty finding markets for recycled newspaper, given the large number of pulp mills in the region as well as the proximity to Asian markets. In other areas of the U.S., however, demand for used newsprint has seen wide fluctuation.[2]

In some U.S. states, a program called RecycleBank pays people to recycle, receiving money from local municipalities for the reduction in landfill space which must be purchased. It uses a single stream process in which all material is automatically sorted.

Much of the difficulty inherent in recycling comes from the fact that most products are not designed with recycling in mind. The concept of sustainable design aims to solve this problem, and was laid out in the book "Cradle to Cradle: Remaking the Way We Make Things" by architect William McDonough and chemist Michael Braungart. They suggest that every product (and all packaging they require) should have a complete "closed-loop" cycle mapped out for each component—a way in which every component will either return to the natural ecosystem through biodegradation or be recycled indefinitely.[4] While recycling diverts waste from entering directly into landfill sites, current recycling misses the dissipative components. Complete recycling is impracticable as highly dispersed wastes become so diluted that the energy needed for their recovery becomes increasingly excessive. "For example, how will it ever be possible to recycle the numerous chlorinated organic hydrocarbons that have bioaccumulated in animal and human tissues across the globe, the copper dispersed in fungicides, the lead in widely applied paints, or the zinc oxides present in the finely dispersed rubber powder that is abraded from automobile tires?"[50]:260 As with environmental economics, care must be taken to ensure a complete view of the costs and benefits involved. For example, paperboard packaging for food products is more easily recycled than most plastic, but is heavier to ship and may result in more waste from spoilage.[51]

Energy and material flows
The amount of energy saved through recycling depends upon the material being recycled and the type of energy accounting that is used. Emergy (spelled with an m) analysis, for example, budgets for the amount of energy of one kind (exergy) that is required to make or transform things into another kind of product or service. Using emergy life-cycle analysis researchers have concluded that materials with large refining costs have the greatest potential for high recycle benefits. Moreover, the highest emergy efficiency accrues from systems geared toward material recycling, where materials are engineered to recycle back into their original form and purpose, followed by adaptive reuse systems where the materials are recycled into a different kind of product, and then by-product reuse systems where parts of the products are used to make an entirely different product.[52]

The Energy Information Administration (EIA) states on its website that "a paper mill uses 40 percent less energy to make paper from recycled paper than it does to make paper from fresh lumber."[53] Some critics argue that it takes more energy to produce recycled products than it does to dispose of them in traditional landfill methods, since the curbside collection of recyclables often requires a second waste truck. However, recycling proponents point out that a second timber or logging truck is eliminated when paper is collected for recycling, so the net energy consumption is the same. An Emergy life-cycle analysis on recycling revealed that fly ash, aluminum, recycled concrete aggregate, recycled plastic, and steel yield higher efficiency ratios, whereas the recycling of lumber generates the lowest recycle benefit ratio. Hence, the specific nature of the recycling process, the methods used to analyse the process, and the products involved affect the energy savings budgets.[52]

It is difficult to determine the amount of energy consumed or produced in waste disposal processes in broader ecological terms, where causal relations dissipate into complex networks of material and energy flow. For example, "cities do not follow all the strategies of ecosystem development. Biogeochemical paths become fairly straight relative to wild ecosystems, with very reduced recycling, resulting in large flows of waste and low total energy efficiencies. By contrast, in wild ecosystems, one population’s wastes are another population’s resources, and succession results in efficient exploitation of available resources. However, even modernized cities may still be in the earliest stages of a succession that may take centuries or millennia to complete."[54]:720 How much energy is used in recycling also depends on the type of material being recycled and the process used to do so. Aluminium is generally agreed to use far less energy when recycled rather than being produced from scratch. The EPA states that "recycling aluminum cans, for example, saves 95 percent of the energy required to make the same amount of aluminum from its virgin source, bauxite."[55][56] In 2009 more than half of all aluminium cans produced came from recycled aluminium.

Economist Steven Landsburg has suggested that the sole benefit of reducing landfill space is trumped by the energy needed and resulting pollution from the recycling process.[59] Others, however, have calculated through life cycle assessment that producing recycled paper uses less energy and water than harvesting, pulping, processing, and transporting virgin trees.[60] When less recycled paper is used, additional energy is needed to create and maintain farmed forests until these forests are as self-sustainable as virgin forests.

Other studies have shown that recycling in itself is inefficient to perform the “decoupling” of economic development from the depletion of non-renewable raw materials that is necessary for sustainable development.[61] The international transportation or recycle material flows through "…different trade networks of the three countries result in different flows, decay rates, and potential recycling returns."[62]:1 As global consumption of a natural resources grows, its depletion is inevitable. The best recycling can do is to delay, complete closure of material loops to achieve 100 percent recycling of nonrenewables is impossible as micro-trace materials dissipate into the environment causing severe damage to the planet’s ecosystems.[63][64][65] Historically, this was identified as the metabolic rift by Karl Marx, who identified the unequal exchange rate between energy and nutrients flowing from rural areas to feed urban cities that create effluent wastes degrading the planet’s ecological capital, such as loss in soil nutrient production.[66][67] Energy conservation also leads to what is known as Jevon’s paradox, where improvements in energy efficiency lowers the cost of production and leads to a rebound effect where rates of consumption and economic growth increases.

The amount of money actually saved through recycling depends on the efficiency of the recycling program used to do it. The Institute for Local Self-Reliance argues that the cost of recycling depends on various factors around a community that recycles, such as landfill fees and the amount of disposal that the community recycles. It states that communities start to save money when they treat recycling as a replacement for their traditional waste system rather than an add-on to it and by "redesigning their collection schedules and/or trucks."[69]

In some cases, the cost of recyclable materials also exceeds the cost of raw materials. Virgin plastic resin costs 40 percent less than recycled resin.[70] Additionally, a United States Environmental Protection Agency (EPA) study that tracked the price of clear glass from July 15 to August 2, 1991, found that the average cost per ton ranged from $40 to $60,[71] while a USGS report shows that the cost per ton of raw silica sand from years 1993 to 1997 fell between $17.33 and $18.10.[72]

In a 1996 article for The New York Times, John Tierney argued that it costs more money to recycle the trash of New York City than it does to dispose of it in a landfill. Tierney argued that the recycling process employs people to do the additional waste disposal, sorting, inspecting, and many fees are often charged because the processing costs used to make the end product are often more than the profit from its sale.[73] Tierney also referenced a study conducted by the Solid Waste Association of North America (SWANA) that found in the six communities involved in the study, "all but one of the curbside recycling programs, and all the composting operations and waste-to-energy incinerators, increased the cost of waste disposal."[74]

Tierney also points out that "the prices paid f

Whitelee wind farm in the snow in December 2010.

Colour balance might be out on this, as it was done on my laptop, which isn’t calibrated!! Desktop computer bit the dust leaving me high and dry for a few days, total pain in the arse! New internals on the way, should be suitably fast, and I can get back on track!

It cost me a fair bit of time and grief, looking forward to being back up and running, also made me think about getting a better system in place for when it happens again, as it inevitably will at some point, bring on the NAS, it’s the best way forward!

Shot this with Mark Ferrier, must have been -10, good to have the company up there, didn’t fancy it on my own, great to catch up with Mark as well!!

🙂
