At present, mankind has faced serious crises of ecological environment destruction by different kinds of rubbish and of resource depletion.

The amount of rubbish from people’s life and economic activities keeps increasing.

On the other hand, the amount of recycled rubbish is rather small.

The rest is burned, buried or even left in the natural world.

According to data, about 2.1 billion tons of rubbish come into being worldwide every year, and it is enough to fill 820 000 Olympic swimming pools.

Besides, about 50 million tons of electronic waste like mobile phones, computers and domestic electrical appliances are discarded every year.

Warning that the annual amount of electronic waste will reach 120 million tons by 2050 unless mankind copes with such a situation in time, an expert expressed concern that it will affects mankind’s use of resources and have a negative effect on many people’s life.

So many countries are making efforts to process waste and rubbish in various ways and reuse them as new resources.

Regarding rubbish as a kind of resources, several countries have set a new goal of economic development, namely an economy with nothing to discard.

Russia works to make effective use of waste on a nationwide scale.

In Sverdlovsk, they have built sorting stations in several residential areas to sort and process various kinds of waste.

On the outskirts of Moscow there are several waste processing factories, each of which produces a lot of energy using hundreds of thousands of tons of waste.

Some countries make bags with old bicycle tyres and use kitchen waste and so on to produce biofuels needed for means of urban transport.

There was developed a new technique of using recycled material mixed with different kinds of waste, including disposable cups, to make concrete that is stronger and longer in lifetime than ordinary concrete.

Besides, methods of mixing waste rubber and construction waste to make a road construction material that is resistant to any external impact and of using mud and coal debris to produce a building material have been invented and introduced.

The work of recycling to solve the problems of resource shortage and waste and at the same time prevent environmental pollution and raise economic effectiveness is getting brisker on a global scale.
