What do people do with their old, out of date but still useful computers? Most people don't know what
to do with them. Many old computers are put away in homes. Many more are simply thrown away as the
rubbish.
Finally, some companies are thinking of ways to bring down the number of old computers. Sony has
agreed to help recycle old Sony products (产品). Dell, Hewlett Packard and other companies now also take
back some old computers.
In some countries, laws have been passed, too. Computer companies have to pay for collecting and
recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is
that computer companies themselves should pay for the cost. That will encourage them to make computers
that are easier and cheaper to repair and upgrade (升级).
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds
of organizations are working to solve this problem. They collect and repair old computers. Some also teach
others how to repair computers. The computers then go to schools, charities (慈善团体) and people who
need them. Giving a used computer to one of these organizations can turn one person's rubbish into someone
else's useful things and cut down waste, too.
