It is an awful lot of rubbish. Since 1960 the amount of municipal waste being collected in America has nearly tripled, reaching 245 million tonnes in 2005. According to European Union statistics, the amount of municipal waste produced in Western Europe increased by 23% between 1995 and 2003, to reach 577kg per person, (So much for the plan to reduce waste per person to 300kg by 2000.) As the volume of waste has increased, so have recycling efforts. In 1980 America recycled only 9.6% of its municipal rubbish, today the rate stands at 32%. A similar trend can be seen in Europe, where some countries, such as Austria and the Netherlands, now recycle,60% or more of their municipal waste. Britain’s recycling rate, at 27%. is low, but it is improving fast, having nearly doubled in the past three years.
  Even so, when a city introduces a kerbside recycling programme, the sight of all those recycling lorries trundling around can raise doubts about whether the collection and transportation of waste materials requires more energy than it saves. "We are constantly being asked: Is recycling worth doing on environmental grounds? says Julian Parfitt, principal analyst at Waste & Resources Action Programme (WRAP), a non-profit British company that encourages recycling and develops markets for recycled materials.
  Studies that look at the entire life cycle of a particular material cam shed light on this question In a particular  case, bat WRAP decided to take a broader look. It asked the Technical University of Denmark and the Danish Topic Centre on Waste to conduct a review of 55 life-cycle analyses, all of which were selected because of their rigorous methodology. The researchers then looked at more than 200 scenarios, comparing the impact of recycling with that of burying or burning particular types of waste material. They found that in 83% of all scenarios that included recycling, it was indeed better for the environment.Based on this study, WRAP calculated that Britain’s recycling efforts reduce its carbon-dioxide emtssions by 10-15 million tonnes per year. That is equivalent to a 10% reduction in Britain’s annual carbon-dioxide emissions from transport, or roughly equivalent to taking 3.5 million cars off the roads. Similarly. America’s Environmental Protection Agency estimates that recycling reduced the country’s carbon emissions by 49 mlllion tonnes in 2005.
  Recycling has many other benefits, too. It conserves natural resources. It also reduces the amount of waste that is buried or burnt, hardly ideal ways to get rid of the stuff. (Landfills take up valuable space and emit methane, a potent greenhouse gas; and although incinerators are not as polluting  as they once were, they still produce noxious emissions, so people dislike having them around.) Butperhaps the most valuable benefit of recycling is the saving in energy and the reduction in greenhouse gases and pollution that result when scrap materials are substituted for virgin feedstock. "If you can use recycled materials, you don’t have to mine ores, cut trees and drill for oil as much," says Jefrey Morris of Sound Resource Management, a consulting firm based in Olympia, Washington. Extracting  metals from ore, in particular, is extremely energy-intensive. Recycling aluminium, for example, can reduce energy consumption by as much as 95%. Savings for other materials are lower but still substantial:  about 70% for plastics, 60% for steel, 40% for paper and 30% for glass. Recycling also reduces  emissions of pollutants that can cause smog, acid rain and the contamination of waterways.
  The virtue of recycling has been appreciated for centuries. For thousands of years metal items have been recycled by melting and reforming them into new weapons or tools. It is said that the broken pieces of the Colossus of Rhodes, a statue deemed one of the seven wonders of the ancient world, were recycled for scrap. During the industrial revolution, recyclers began to form businesses and later trade associations, dealing in the collection, trade and processing of metals and paper. America’s Institute of Scrap Recycling Industries (ISRI), a trade association with more than 1,400 member companies, traces its roots back to one such organization founded in 1913. In the 1930s many people survived the Great Depression by peddling scraps of metal, rags and other items. In those days reuse and recycling were often economic necessities. Recycling also played an important role during the Second World War, when scrap metal was turned into weapons.
  As industrial societies began to produce ever-growing quantities of garbage, recycling took on a new meaning. Rather than recycling materials for purely economic reasons, communities began to think about how to reduce the waste flow to landfills and incinerators. Around 1970 the environmental movement sparked the creation of America’s first kerbside collection schemes, though it was another 20 years before such programmes really took off. In 1991 Germany made history when it passed an ordinance shifting responsibility for the entire life cycle of packaging to producers. In response, the industry created Duales System Deutschland (DSD), a company that organises a separate waste management system that exists alongside public rubbish-collection. By charging a licensing fee for its "green dot" trademark, DSD pays for the collection, sorting and recycling of packaging materials. Although the system turned out to be expensive, it has been highly influential. Many European countries later adopted their own recycling initiatives incorporating some degree of producer responsibility.
In 1987 a rubbish-laden barge cruised up and down America’s East Coast looking for a place to unload, sparking a public discussion about waste management and serving as a catalyst for the country’s growing recycling movement. By the early 1990s so many American cities had established recycling programmes that the resulting glut of materials caused the market price for kerbside recyclables to fall from around $50 per ton to about $30, says Dr Morris, who has been tracking prices for recyclables in the Pacific Northwest since the mid-1980s. As with all commodities, costs for recyclables fluctuate. But the average price for kerbside materials has since slowly increased to about $90 per ton. Even so, most kerbside recycling programmes are not financially self-sustaining. The cost of collecting, transporting and sorting materials generally exceeds the revenues generated by selling the recyclables, and is also greater than the disposal costs. Exceptions do exist, says Dr Morris, largely near ports in dense urban areas that charge high fees for landfill disposal and enjoy good market conditions for the sale of recyclables.
