Recycling makes things like paper or glass or
metal useful again. It means the resources that went into making them were
not wasted. With glass, it is said that for every one thousand kilograms
recycled, one thousand two hundred kilograms of raw materials are saved.
Recycling also means that communities have to deal with less waste.

The process of recycling can give things not
only a new life but, in some cases, a different one. Glass bottles, for
example, can become drinking glasses.

First, the base is removed from the bottle. Then
the bottle is turned upside down and the neck is attached to the base. The
used bottle that would have been thrown away has now become a good looking
drinking glass.

It is not easy to make this happen, though. The
biggest problem is how to attach the base to the neck of the bottle turned
upside down.

Two South African businessmen, Sean Penrith and
Philip Tetley, looked for a large glass manufacturer that could do it. But
they had no luck. So they experimented for eight months. Many broken
bottles later, they found a way.

Their company, called Green Glass, won a
Business of the Year award in nineteen ninety-four. It was voted among the
best new businesses in South Africa. The inventors received worldwide
patent rights to own the process they developed.

More recently, the Green Glass idea has expanded
into markets in Europe and the United States.

Green Glass U.K. says on its Web site that it now makes one hundred fifty
thousand glasses per year. The factory in Cornwall, England, employs ten
people.

The company says it saves ninety percent of the energy normally used to
make recycled glass. The energy is saved because the glass is not melted.
The glass is heated, however, to strengthen it.

The Green Glass process takes about three hours to make a bottle into a
drinking glass. The bottle goes through seven machines, all designed and
built by the company itself. Broken bottles cannot be used. So Green Glass
U.K. says it must find bottles anywhere it can.
