Disposing of the garbage we produce every day is a major problem in cities around the world. In the United States, over 160 million tons of garbage is produced every year. Ten percent is recycled, ten percent is burned, and the rest is put in landfills. But finding land for new landfills is becoming more difficult.
A city that has solved this problem in an unusual way is Machida in Tokyo. They have developed a totally new way of dealing with garbage. The key to the operation is that people should work together. Families must divide their garbage into six groups:
1 garbage that can be easily burned, such as kitchen and garden trash
2 garbage that doesn’t burn easily, such as plastic tools and plastic toys
3 products that are poisonous or that cause pollution, such as batteries
4 bottles and glass containers that can be recycled
5 metal containers that can be recycled
6 large items, such as furniture and bicycles
The items in Groups 1 to 5 are collected on different days. Large items are only collected upon request. Then the garbage is taken to a centre that looks like a clean new office building or hospital. Inside the centre, special equipment is used to sort and deal with garbage. Almost everything can be reused: garden or kitchen trash becomes fertilizer; garbage that can burn is burned to produce electricity; metal containers and bottles are recycled; and old furniture, clothing, and other useful items are cleaned, repaired, and resold cheaply or given away. The work provides employment for the disabled and gives them a chance to learn new skills.
Nowadays, officials from cities around the world visit Machida to see whether they can use some of these ideas and techniques to solve their own garbage problems.
