Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dustbin would be made into something useful. Even the most dangerous and unpleasant wasteswould provide energy if nothing else.
The new concept of recycling waste is taking shape at the British Technological Laboratory at Warren Spring, not far from the north of London. Today, the laboratory spends four times as much money in studying recycling as it did five years ago.
The latest project is to take a city of around half a million inhabitants 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 outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Methods have been discovered, for example, for removing the ink from newsprint so that the paper can be used again, and for obtaining valuable oils and gases from old motor car types. All these ideas are already being made use of, but what is new is the idea of combining them on such a large scale in a single plant designed to recycle most types of waste.
Another new project 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 spikes which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that crushers and rollers will break up everything that can be broken finally, and the rubbish will pass under magnets, which will remove the bits of iron and steel; finely the rubber and plastic will then be sorted out in the final stage.
The first full-scale giant recycling plants are, perhaps, fifteen years away. But in some big industrial areas, where rubbish has been dumped for so long that there are no holes left to fill up with rubbish, these new automatic recycling plants may be built sooner. 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] The passage is mainly about______.
