废旧塑料资源被现代经济学家称为“人类的第二大矿藏”、“城市里的宝藏”。据有关部门统计，我国的一个中等城市每年产生的塑料废弃物可满足20家小型塑料企业的原材料需求。开发利用废旧塑料资源既可有效治理污染，又可创造巨大的经济效益，是一件利国利民的绿色环保事业。（选自《科技日报》，2005年8月4日）
The resources of waste plastics are called by modern economists “the second greatest mineral resource of mankind” or “the treasure of the city.” Statistics made by relevant departments show that, in China, the waste plastics from a medium-sized city per year can meet the raw material demand of 20 small plastic enterprises. The exploitation of waste plastics not only can bring pollution under effective control, but also can create huge economic returns, which is proved an environment-friendly undertaking beneficial both to the country and to the people.
