With fifteen years Britain and other nations should be well on with the building

With fifteen years Britain and other nationsshould be well on with the building of big industrial plants for therecycling of waste. The word rubbish could lose its meaning because everythingwhich goes into the dustbin would be made into something useful. Even the mostdangerous and unpleasant wastes would provide energy of nothing else.

The latest project is to take a city ofaround half a million citizens and discover exactly what raw (未经加工的) materials go into itand what go out. The aim is to find out how much of these raw materials couldbe provided if a plant for recycling waste were built just outside the city.This plant would recycle not only metal such as steel, lead and copper, butalso paper and rubber as well.

Another new project is being set up todiscover the best ways of sorting and separating the rubbish. When this projectis complete, the rubbish will be treated like this: First, it will pass throughsharp metal bars which will tear open the plastic bags in which rubbish isusually packed; then it will pass through a powerful fan to separate thelightest elements (元素) from the heavy solids; after that rollers will break up everythingthat can be broken. Finally, the rubbish will pass under magnets (磁铁), which will remove the bits of iron and steel; the rubber andplastic will then be sorted out in the final step.

The first full-scale (全方位的) big recycling plantsare perhaps fifteen years away. Indeed, with the growing cost of transportingrubbish to more distant dustbins, some big cities will be forced to build theirown recycling plants before long.
