Recycling of materials has become common practice over the last ten years or so, with households in many countries encouraged to save used cans, glass, plastics, paper and garden rubbish for special collection. These are then recycled for two main reasons.
One is local, to save land which would otherwise be used as dumps for the waste. In the European Union alone, 1.3 billion tonnes of waste - some 40 million tonnes of it hazardous - are thrown away annually. This amounts to about 3.5 tonnes of solid waste for every man, woman and child. On top of this there is also a further 700 million tonnes of agricultural waste to dispose of. The other main reason for recycling has global significance - to help conserve valuable resources, such as metals, wood and energy.
This unit is devoted to the recycling of metals, some basic chemicals and polymers, all within the context of the chemical industry.
