There are 4 sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste.
Material waste can be recycled and reused. Such as metal, paper, glass, plastics and rubber. Old papers can be recycled. The ink is taken out by a special technique and new paper is made. Empty glass bottles are collected and the glass is broken and reused for new bottles.
Organic waste is from all living things and kitchens, such as leftover food, unfresh vegetables and so on. They can be reused as well. They can make crops grow better. And this kind of crops is called “green crops”. They are safe to eat and are considered as “healthy food”.
Inorganic waste such as building waste, broken pottery and china and cinder cannot be reused. But this kind of waste is becoming more and more day by day. So if they are not treated correctly, they will cause serious problems.
The last is poisonous & harmful waste. Batteries, medical waste, electrical waste and old electrical apparatus all belong to poisonous and harmful waste. They are dangerous to us. Some dangerous waste can be put into metal containers and thrown into the deep sea. It will be many years before the chemicals start to escape from the containers. At the bottom of the ocean there is very little life and movement of water. All radioactive waste must be stored on land.
That’s to say, if waste is collected, sorted, recycled and reused, it will save a lot of natural resources and energy. Waste is a resource at a wrong place, depending on how people treat it.
As for me, I’ll do whatever I can to help. First, I’ll throw away waste at the right place. Second, I’ll use materials that may be recycled and refuse to use materials causing “white pollution”. Third, I’ll sell the old papers and glass bottles to the Recycle Station. If everyone gives a hand, waste will be resources at the right place!
Hand in hand, let’s build a beautiful planet!
