随着工业发展及日用生活消费品的不断增长。工业废弃物和生活垃圾都在迅速增长,据专家们粗略估计,全世界一年产出的垃圾数量为100×10~8t。过去由于生活垃圾的构成比较简单,因此,大部分可作为肥料用于农田。然而当今的垃圾内容物已产生很大变化,其最大的特点是废塑料、废橡胶和废纸等可燃性物质的比例在增加,因而以往的再生利用方法已不适用。垃圾是我们的废弃物,其实也是我们的一笔能源财富。
With the continuous development of industrial development and consumer goods for daily use. Industrial waste and household waste are rapidly growing. According to rough estimates, experts estimate that the amount of garbage produced each year in the world is 100×10-8 tons. In the past, the composition of domestic garbage was relatively simple, so most of it can be used as fertilizer for farmland. However, today’s garbage content has undergone great changes. Its greatest feature is the increase in the proportion of combustible materials such as waste plastics, waste rubber, and waste paper. As a result, past recycling methods have not been applied. Garbage is our waste, but it is also our energy wealth.
