LET US UNDERSTAND THE TEXT
20.2.1 PART – 1
Recycling rubbish ……………….. even some plastics.
Reusing rubbish is one of the important ways of reducing pollution. Rubbish which is not reused is disposed of by burning. This leads to pollution. The cutting down of thousands of trees for the purpose of printing newspapers leads to a waste of the earth’s resources. Instead, if we reuse the most commonly used paper, metal, glass and plastic objects, it will help us save natural resources and our environment.

Metal products can be reused in many ways. Metal recycling not only saves natural resources, but also a lot of electricity and energy.

20.2.3 PART – 3
Glass is best…………… all of us need to think about.
The best way to save glass is to reuse glass bottles and other glass objects to the maximum. Glass can also be recycled to form new glass objects. Recycling broken glass of mixed colours only produces green coloured glass. Therefore, the best way to recycle glass is to separate broken glass by colour, and then remelt it to produce new glass objects. Another important material that should be recycled is paper, as half of the world’s waste is paper. In general in India we reuse a lot of things and avoid waste. But in the twenty first century we Indians copy some of the wasteful habits of people in western countries (such as using more and more disposable paper items for the sake of convenience). We should be aware of these changes in our habits and try to control them. All of us should try to check waste in any form.

Plastic is one of the most difficult substances to recycle, because it comes in so many varieties. Some plastic bottles, for example, consists of six layers of different types of plastic, each designed to give the bottles certain qualities – shape, strength, flexibility. And as yet there is no simple way to turn an old plastic bottle into a new one.
Plastic scrap can only be turned into a product of lower quality a plastic might be cleaned, cut into very very tiny pieces and used to stuff seat cushions, a mixture of plastic waste can be recycled into plastic ‘timber’ and used to make durable fencing. But a lot of plastic waste still has to be thrown away.

Ans. Some plastic bottles contain six layers of different types of plastic.

Metals are different Any car on the road today will consist, in part, of earlier cars that have been scrapped and recycled into new steel and other metals.

Glass is also worth recovering. The most sensible method is to use glass bottles as often as possible. In countries which still use milk bottles, the average bottle makes about 30 trips to and from the dairy.
Broken glass known as ‘cullet’ can also be recycled, and many western countries have bottle banks into which used bottles can be thrown. Usually there are payments. Bottle banks depend on people’s goodwill. The success of bottle banks varies widely from country to country. The Swiss and Dutch recover 50 percent of their glass, while in Britain only 12 percent is recovered. In India of course, we sell our bottles which are then reused.

The Swiss and Dutch recover 50 percent of their glass, while in Britain only 21 percent is recovered. In India, of course, we sell our bottles which are then reused.

Broken glass can be remelted in furnaces and then it can easily be shaped into new bottles or other objects.
1. Name two countries that recover high percentage of glass.
Ans. These countries are Swiss and Dutch.
