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. After many bottles were broken, they found a way.
Their company, called Green Glass, won a Business of the Year award in 1994. It was voted among the best new businesses in South Africa. The inventors received worldwide patent rights to own the process they developed.
A. The new way of recycling used bottles is said to save 10 percent of the energy normally used to make recycled glasses.
B. Each year, Green Glass Company makes 150,000 glasses at most.
C. Many bottles are broken when making a new drinking glass.
D. The seven machines used to make glasses are all designed and built by the company itself.
