问题     With fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the【B1】______of waste. The word rubbish could lose its meaning because everything which goes into the dumps(垃圾堆)would be made into something【B2】______. Even the most dangerous and【B3】______wastes would provide energy if nothing else.
    The latest project is to take a city of around half a million【B4】______and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just【B5】______the city. This plant would recycle not only metal such as steel, lead and【B6】______, but also paper and rubber as well.
    Another new【B7】______is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: First, it will pass through sharp metal bas which will tear open the【B8】______bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids;【B9】______Finally, the rubbish will pass under magnets(磁铁), which will remove the bits of iron and steel;【B10】______.
【B11】______Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long. [br] 【B6】
