In industry, most glass (recycle) is recycled, but ordinary people are often too lazy to do this. They throw their bottles away, and the bottles (take) are taken to the clump. It's difficult for workers on the dump to separate glass from other waste. That is why there are ''bottle banks '' to encourage people to recycle glass. The glass (collect) is collected and (take) taken to the factory. There it (break) is broken up, (melt) melted and (make) made into new bottles.
