Question

Recycling is a way to change waste materials into new products, so that they can be used more than once.

Quite a lot of materials can be recycled， such as plastics，glass，paper，electronics(电子器件)and so on. There are many used items made of these materials in our everyday life， like soda cans,water bottles, newspapers, and old computers.

Recycling, in fact,is not a simple process and it is different for each type of material. For example, to start recycling paper, people will mix it with water and some chemicals to break it down. In this way, the paper will be turned into pulp(纸紫).Then the glues or plastics will be removed from the pulp. After that,it gets cleaned to remove any' inks or dyes(染料). Now the pulp is ready to be made into new paper.

However, computers and batteries are usually recycled in order to remove harmful chemicals as well as to find again some useful materials such as gold.

Do you know the recycling symbol? It has three arrows(箭头)，which stand for three different steps in the recycling process. First, collect recyclable materials. Second, process the old materials and make new items. Third, buy items made from recycled materials.
