In 1993, New York State ordered stores
to charge a deposit on beverage (饮料) containers. Within a year, consumers had
returned millions of aluminum cans and glass and plastic bottles. Plenty of
companies were eager to accept the aluminum and glass as raw materials for new
products, but because few could figure out what to do with the plastic, much of
it wound up buried in landfills (垃圾填埋场). The problem was not limited to New
York. Unfortunately, there were too few uses for second-hand plastic. Today, one out of five plastic soda bottles is recycled(回收利用)in the United States. The reason for the change is that now there are dozens of companies across the country buying discarded plastic soda bottles and turning them into fence posts, paint brushes, etc. As the New York experience shows, recycling involves more than simply separating valuable materials f A. to sell them at a profitable price B. how to turn them into useful things C. how to reduce their recycling costs D. to lower the prices for used materials [不定项选择题]A.水利尿
