London saves around thirty million pounds each year through recycling. The saving can be made as it is cheaper to recycle than to landfill. Financial support for recycling is available for London boroughs through the Recycle for London’s Borough Service Support programme. London boroughs may request funds for advice on communications as well as for recycling, reuse and waste prevention issues that focus on delivering more recycling or composting leading to less landfill from homes. The future aims include recycling of business waste. 토토사이트
Recycling involves treating waste used materials to produce new goods. The benefits include:-
• Less fresh materials are required.
• Possible useful materials are not thrown-away.
• Less water contamination associated with landfills.
• Reduced air pollution associated with burning.
• A reduction of conventional waste disposal.
• New job and business creation for haulage, processing and selling recovered materials, as well as companies that distribute products made with the recycling.
In some types of recycling, the useful material must be salvaged from quite complex products, for example lead from batteries or gold from computer hardware.
In a perfect world, recycling of any product would repeatedly produce a fresh supply of the same product. However this is frequently impossible, office paper being a prime example. Recycling, therefore, necessarily often results in different materials such as paperboard.
The History of Recycling
Recycling has been practiced for millennia. Archaeological digs have demonstrated that when resources were scarce, waste dumps revealed less household waste materials such as ash and broken tools and utensils indicating that used materials were being recycled to supplement new materials.
When there is conflict, international trade may not be feasible, and this motivates governments to legislate in favour of recycling. During the Second World War, for example, the governments of every country involved imposed strict rules and regulation on its people. Politicians came to see the advantages of recycling even in peace-time. This was especially relevant for countries such as Japan with few natural resources.
From the 1970s onwards, the price of energy has been rising rapidly. The energy requirements to produce virgin aluminium are twenty-fold that required for recycling. The energy factor similarly comes into play for other metals and glass,
The Recycling Process
For a recycling program to function efficiently there needs to be a large on-going supply of recyclable material. Many countries now operate obligatory collection laws that determine targets that cities must achieve. This is frequently in the form of a proportion of material that must be diverted from the city’s waste.
Powerful magnets are used to separate out ferrous metals, such as iron, steel, and tin-plated cans. Non-ferrous metals are removed by magnetic eddy currents.
Glass has to be sorted manually according to colour.
The Economics of Recycling
A large portion of waste comes from industry. Some people question whether recycling is economically efficient and the focus of many recycling programs in industry is understandably cost-effectiveness. One dilemma is that most products are not designed with recycling in mind. As energy costs go up, industry may come to appreciate that long-term planning should include recycling.
