Recycling is a technology that helps protect the environment and cut down on usage of raw materials. the steel, paper and glass industries recycle a lot. the largest recycler is the steel industry. it recovers more than 70 per cent of its original materials. for example, since 1988 they have produced the majority of new metal cans from old ones. metal parts for cars and planes are other examples of recycling steel. fragments of waste glass are widely used in construction. for producing writing paper and pens, used packing boxes are an ideal material. they are cheap and easy to recycle. nowadays more and more recycling centres are appearing in our towns and cities.выпишите правильные и не правильные глаголы, выпишите прилогательное
