RECYCLING ELECTRONIC WASTE

Millions of new TVs, fridges, air-conditioning units and washing machines are bought every day around the world. So what happens to the old ones? In Japan, where around 20 million electrical appliances are dumped by the side of the road or in rivers every year, new legislation was introduced in 2001 which means that all electrical goods must be 50-60% recyclable.

Recycling these high tech machines isn't easy. They can't just be smashed into small pieces that can be used again. Special plants, like the Matsushita Eco-Technology Centre, are required for the process. Each appliance is taken apart very carefully and the components are sorted into different categories. The plastic in these machines, for example, is collected and reused to make internal components for new appliances.

Although Matsushita, who owns Panasonic, is criticized by some people for creating the problem in the first place, most people agree that progress has been made in dealing with this space age environmental challenge.
