Recycling

Recycling is processing used materials (waste) into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energyusage(SONY VAIO VGN-FZ190 Battery), 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 virgin production. Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy(SONY VAIO VGN-FZ150E Battery).

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 not typically considered recycling(SONY VAIO VGN-FZ260E Battery). 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(SONY VAIO VGN-FZ140E Battery).

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 usedfoamed polystyrene into new polystyrene(SONY VAIO VGN-FZ11l Battery). 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(SONY VAIO VGN-FZ11z Battery). 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) (SONY VAIO VGN-FZ11m Battery). 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(SONY VAIO VGN-FZ18m Battery), 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(SONY VAIO VGN-FZ21m Battery), 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(SONY VAIO VGN-FZ410 Battery).

History

Origins

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 (SONY VAIO VGN-FZ21 Battery) (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(SONY VAIO VGN-FZ160 Battery). 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(SONY VAIO VGN-FZ210CE Battery), as well as a lack of public waste removal in ever more densely populated areas. In 1813, Benjamin Law developed the process of turning rags into 'shoddy' and 'mungo' wool in

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(SONY VAIO VGN-FZ38M Battery).

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(SONY VAIO VGN-FZ31z Battery), 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(Sony Vaio VGN-FZ31S battery), 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(SONY VAIO VGN-FZ31E Battery).

Wartime

Resource shortages caused by the world wars, and other such world-changing occurrences greatly encouraged recycling. 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(SONY VAIO VGN-FZ31J Battery), as a matter of significant patriotic importance. For example in 1939, Britain launched the programme Paper Salvage to encourage the recycling of materials to aid the war effort. Resource conservation programs established during the war were continued in some countries without an abundance of natural resources, such as Japan, after the war ended(SONY VAIO VGN-FZ31M Battery).

Post-war

The next big investment in recycling occurred in the 1970s, due to rising energy costs. Recycling aluminium uses only 5 percent of the energy required by virgin production; glass, paper and metals have less dramatic but very significant energy savings when recycled feedstock is used(SONY VAIO VGN-FZ31B Battery).

Legislation

Supply

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(HP PAVILION DV6000 battery), 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(SONY VGP-BPS13 Battery).

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(SONY VGP-BPS13B/B Battery). 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(ASUS EEE PC battery). 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(ASUS EEE PC900 battery).

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(Dell INSPIRON 1525 battery). Care must be taken that enough of these recycling services exist, or such bans simply lead to increased illegal dumping.

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(Dell INSPIRON E1505 battery).

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(Dell INSPIRON 1420 battery). 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(Dell INSPIRON 1520 battery).

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(Dell INSPIRON 1464 battery), 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(Dell INSPIRON 1564 battery).

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) (Dell INSPIRON 1764 battery), 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(Dell N3010 Battery), 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(SONY VGP-BPS13/B Battery).

Recycling consumer waste

Collection

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"(Sony VAIO VGN-FZ15T Battery).

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(Sony VAIO VGN-FZ15G Battery).

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(SONY VGP-BPS13A/S Battery). Unfortunately government subsidies are necessary to make buy-back centres a viable enterprise, as according to the United States Nation Solid Wastes Management Association it costs on average US$50 to process a ton of material, which can only be resold for US$30(SONY VGP-BPS13AS Battery).

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. A waste collection vehiclegenerally picks up the waste(SONY VGP-BPS13S Battery).

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(SONY VGP-BPS13B/S Battery). 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(SONY VAIO PCG-5G2L battery). Any changes to which materials are recyclable is easy to accommodate as all sorting happens in a central location.

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(SONY VAIO PCG-5G3L battery).

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(SONY VAIO PCG-5J1L battery), 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(SONY VAIO PCG-5K2L battery).

Source separation used to be the preferred method due to the high sorting costs incurred by commingled 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(SONY VAIO PCG-5L1L battery).

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 truck-load of material can be fully sorted in less than an hour(SONY VAIO PCG-5J2L battery). Some plants can now sort the materials automatically, known as single-stream recycling. A 30 percent increase in recycling rates has been seen in the areas where these plants exist(SONY VAIO PCG-6S2L battery).

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(SONY VAIO PCG-6S3L battery).

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(SONY VAIO PCG-6V1L battery). 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(SONY VAIO PCG-6W1L battery).

Strong magnets are used to separate out ferrous metals, such as iron, steel, and tin-plated steel cans ("tin cans"). Non-ferrous metals are ejected by magnetic eddy currents in which a rotating magnetic field induces an electric current around the aluminium cans(SONY VAIO PCG-7111L battery), 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.

Finally, glass must be sorted by hand based on its color: brown, amber, green or clear.

Recycling industrial waste(SONY VAIO PCG-6W3L battery)

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(SONY VAIO PCG-7113L battery). 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(SONY VAIO PCG-7133L battery). 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(SONY VAIO PCG-7Z1L battery).

The military also recycles waste products, especially 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(SONY VAIO PCG-7Z2L battery).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(SONY VAIO PCG-8Y1L battery), and it is used by all branches of the U.S. military use for armor-piercing shells and shielding. The construction industry may recycle concrete and old road surface pavement, selling their waste materials for profit(SONY VAIO PCG-8Y2L battery).

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 theSociety of the Plastics Industry, Inc(SONY VAIO PCG-8Z2L battery). 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(SONY VAIO PCG-8Z1L battery).

Cost-benefit analysis

There is some debate over whether recycling is economically efficient. Municipalities often see fiscal benefits from implementing recycling programs, largely due to the reduced landfill costs(SONY VAIO PCG-7112L battery). A study conducted by the Technical University of Denmark found that in 83 percent of cases, recycling is the most efficient method to dispose of household waste. 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(SONY VAIO PCG-6W2L battery).

Fiscal efficiency is separate from economic efficiency. Economic analysis of recycling includes what economists call externalities, which are unpriced costs and benefits that accrue to individuals outside of private transactions(SONY VAIO PCG-5K1L battery). Examples include: decreased air pollution and greenhouse gases from incineration, reduced hazardous waste leaching from landfills, reduced energy consumption, and reduced waste and resourceconsumption(SONY pcga-bp2ea battery), which leads to a reduction in environmentally damaging mining and timber activity. About 4000 minerals are known, of these only a few hundred minerals in the world are relatively common(SONY VGP-BPS21A/B Battery). At current rates, current known reserves of phosphorus will be depleted in the next 50 to 100 years. Without mechanisms such as taxes or subsidies to internalize externalities, businesses will ignore them despite the costs imposed on society(SONY VGP-BPS21B Battery). To make such non-fiscal benefits economically relevant, advocates have pushed forlegislative action to increase the demand for recycled materials. 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(SONY VGP-BPS21 Battery). 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. Recycling is more efficient in densely populated areas, as there are economies of scale involved(SONY VGP-BPS21/S Battery).

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(SONY Vaio PCG-F305 battery), 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"(SONY VGP-BPS13A/Q Battery).

Many 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(SONY VGN NR11Z/T battery). However, those of the laissez faire approach to municipal recycling see product disposal as a service that consumers value. A free-market approach is more likely to suit the preferences of consumers since profit-seeking businesses have greater incentive to produce a quality product or service than does government(SONY VGN NR11Z/S battery). Moreover, economists almost always advise against government intrusion in any market with little or no externalities.

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(SONY VGN NR11M/S battery). According to one report, in America, 50–80 percent of computers destined for recycling are actually not recycled. 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(SONY VGN NR11S/S battery). Though the Chinese government has banned these practices, it has not been able to eradicate them. In 2008, the prices of recyclable waste plummeted before rebounding in 2009. Cardboard averaged about £53/tonne from 2004–2008, dropped to £19/tonne(SONY VGP-BPS13B/Q Battery), 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. Certain regions have difficulty using or exporting as much of a material as they recycle(SONY VGP-BPS13Q Battery). 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 theAmerican Midwest there is not enough wine production to use all of the reprocessed material(SONY Vaio VGN-FW21M Battery). The extra must be downcycled into building materials or re-inserted into the regular waste stream.

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(SONY Vaio VGN-FW21L Battery).

In some U.S. states, a program called RecycleBank pays people with coupons 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(SONY Vaio VGN-FW21J Battery).

Benefits and Criticisms

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(SONY Vaio VGN-FW21E Battery), and was laid out in the book "Cradle to Cradle: Remaking the Way We Make Things" by architect William McDonough and chemistMichael Braungart. They suggest that every product (and all packaging they require) (SONY Vaio VGN-FW11S Battery) 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(SONY Vaio VGN-FW11M Battery).

As with environmental economics, care must be taken to ensure a complete view of the costs and benefits involved. For example, cardboard packaging for food products is more easily recycled than plastic, but is heavier to ship and may result in more waste from spoilage(SONY Vaio VGN-FW11 Battery).

The following are criticisms of many popular points used for recycling.

Saves energy

The amount of energy saved through recycling depends upon the material being recycled. Some, such as aluminum, save a great deal, while others may not save any. TheEnergy 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(SONY VAIO VGN-FZ21J Battery)." 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(SONY VAIO VGN-FZ21Z Battery).

It is difficult to determine the exact amount of energy consumed or produced in waste disposal processes. How much energy is used in recycling depends largely on the type of material being recycled and the process used to do so(SONY VAIO VGN-FZ21E Battery). 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(SONY Vaio VGN-FW31M Battery)."

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(SONY Vaio VGN-FW465J Battery). 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. 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(SONY Vaio VGN-FW139E/H Battery).

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(SONY Vaio VGN-FW139E Battery). When global consumption of a natural resource grows by more than 1 percent per annum, its depletion is inevitable, and the best recycling can do is to delay it by a number of years. Nevertheless, if this decoupling can be achieved by other means(SONY Vaio VGN-FW31E Battery), so that consumption of the resource is reduced below 1 percent per annum, then recycling becomes indispensable – indeed recycling rates above 80 percent are required for a significant slowdown of the resource depletion(SONY Vaio VGN-FW17W Battery).

Saves money

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(SONY Vaio VGN-FW32J Battery), 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(SONY Vaio VGN-FW31J Battery)."

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. Additionally, aUnited States Environmental Protection Agency (EPA) study that tracked the price of clear glass from July 15 to August 2, 1991(SONY VGN-CR42E battery), found that the average cost per ton ranged from $40 to $60, 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(SONY VGN-CR42S battery).

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(SONY VGN-CR42Z battery), 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. 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(SONY VGN-CR42ZR battery), "all but one of the curbside recycling programs, and all the composting operations andwaste-to-energy incinerators, increased the cost of waste disposal."

Tierney also points out that "the prices paid for scrap materials are a measure of their environmental value as recyclables. Scrap aluminum fetches a high price because recycling it consumes so much less energy than manufacturing new aluminum(SONY VGN-CR41SR battery)."

Working conditions

Critics often argue that while recycling may create jobs, they are often jobs with low wages and terrible working conditions. These jobs are sometimes considered to be make-work jobs that don't produce as much as the cost of wages to pay for those jobs(SONY VGN-CR41E battery). In areas without many environmental regulations and/or worker protections, jobs involved in recycling such as ship breaking can result in deplorable conditions for both workers and the surrounding communities(SONY VGN-CR41S battery).

Recycling proponents counter that the jobs involved in recovery of an equal amount of virgin material creates worse jobs. Timber harvesting and ore mining are more dangerous than paper recycling and metal recycling(SONY VGN-CR41Z battery).

Saves trees

Economist Steven Landsburg, author of a paper entitled "Why I Am Not an Environmentalist," has claimed that paper recycling actually reduces tree populations. He argues that because paper companies have incentives to replenish the forests they own(SONY VGN-CR31Z battery), large demands for paper lead to large forests. Conversely, reduced demand for paper leads to fewer "farmed" forests. Similar arguments were expressed in a 1995 article for The Free Market(SONY VGN-CR31E battery).

When foresting companies cut down trees, more are planted in their place. Most paper comes from pulp forests grown specifically for paper production. Manyenvironmentalists point out, however(SONY VGN-CR31S battery), that "farmed" forests are inferior to virgin forests in several ways. Farmed forests are not able to fix the soil as quickly as virgin forests, causing widespread soil erosion and often requiring large amounts of fertilizer to maintain while containing little tree and wild-life biodiversity compared to virgin forests(SONY VGN-CR31SR battery). Also, the new trees planted are not as big as the trees that were cut down, and the argument that there will be "more trees" is not compelling to forestry advocates when they are counting saplings(SONY VGN-CR21SR battery).

The recycling of paper should not be confused with saving the tropical forest. Many people have the misconception that paper-making is what's causing deforestation of tropical rain forests but rarely any tropical wood is harvested for paper(SONY VGN-CR21Z battery). Deforestation is mainly caused by population pressure such as demand of more land for agriculture or construction use. Therefore, the recycling paper, although reduces demand of trees, doesn't greatly benefit the tropical rain forests(SONY VGN-CR21S battery).

Possible income loss and social costs

In some prosperous and many less prosperous countries in the world, the traditional job of recycling is performed by the entrepreneurial poor such as the karung guni, Zabaleen, the rag and bone man, waste picker, and junk man(SONY VGN-CR21E battery). With the creation of large recycling organizations that may be profitable, either by law or economies of scale, the poor are more likely to be driven out of the recycling and the remanufacturingmarket(SONY VGN-CR11E battery). To compensate for this loss of income to the poor, a society may need to create additional forms of societal programs to help support the poor. Like the parable of the broken window, there is a net loss to the poor and possibly the whole of a society to make recycling artificially profitable through law(SONY VGN-CR11M battery). However, as seen in Brazil and Argentina, waste pickers/informal recyclers are able to work alongside governments, in (semi)funded cooperatives, allowing informal recycling to be legitimized as a paying government job(SONY VGN-CR11S battery).

Because the social support of a country is likely less than the loss of income to the poor doing recycling, there is a greater chance that the poor will come in conflict with the large recycling organizations(SONY VGN-CR11Z battery). This means fewer people can decide if certain waste is more economically reusable in its current form rather than being reprocessed. Contrasted to the recycling poor, the efficiency of their recycling may actually be higher for some materials because individuals have greater control over what is considered “waste.” (SONY VGN-CR11SR battery)

One labor-intensive underused waste is electronic and computer waste. Because this waste may still be functional and wanted mostly by the poor, the poor may sell or use it at a greater efficiency than large recyclers(SONY VAIO VGN-NR110E/W battery).

Many recycling advocates believe that this laissez-faire individual-based recycling does not cover all of society’s recycling needs. Thus, it does not negate the need for an organized recycling program. Local government often consider the activities of the recycling poor as contributing to property blight(SONY VAIO VGN-NR110E/S battery).

Public participation in recycling programmes

Many studies have addressed recycling behaviour and strategies to encourage community involvement in recycling programmes. It has been argued that recycling behaviour is not natural because it requires a focus and appreciation for long term planning(SONY VAIO VGN-NR110E/T battery), whereas humans have evolved to be sensitive to short term survival goals; and that to overcome this innate predisposition, the best solution would be to use social pressure to compel participation in recycling programmes. However, recent studies have concluded that social pressure is unviable in this context(SONY VAIO VGN-NR110E battery). One reason for this is that social pressure functions well in small group sizes of 50 to 150 indiviudals (common to nomadic hunter-gatherer peoples) but not in communities numbering in the millions, as we see today. Another reason is that individual recycling does not take place in the public view(SONY VAIO VGN-NR11S battery). In a study done by social psychologist Shawn Burn , it was found that personal contact with individuals within a neighborhood is the most effective way to increase recycling within a community. In his study, he had 10 block leaders talk to their neighbors and convince them to recycle(SONY VAIO VGN-NR11Z battery). A comparison group was sent fliers promoting recycling. It was found that the neighbors that were personally contacted by their block leaders recycled much more than the group without personal contact(SONY Vaio VGN-CR11S/L battery). As a result of this study, Shawn Burn believes that personal contact within a small group of people is an important factor in encouraging recycling. Another study done by Stuart Oskamp examines the effect of neighbors and friends on recycling(SONY Vaio VGN-CR11S/P battery). It was found in his studies that people who had friends and neighbors that recycled were much more likely to also recycle than those who didn’t have friends and neighbors that recycled(SONY Vaio VGN-CR11S/W battery).
