我国已是“白色污染”十分严重的国家。据有关资料统计,就PVC一项的消耗,到本世纪末,我国将达到人均1.7kg/年的水平。如果再加上其它聚合物材料的应用,其数量将十分惊人。而目前对于废弃的塑料制品除少量重新回收利用外,多采取焚烧、填埋、倒入海中等方法处理。由于这类塑料制品在自然界中的分解十分缓慢(约需200年),势必将造成严重的污染和对生态环境不可估量的破坏。为此,人们采用了各种方法来解决这一问题,如以纸制品
Our country is already a country with “white pollution” very serious. According to statistics, on the consumption of PVC, by the end of this century, China will reach the level of 1.7kg per capita per year. If coupled with the application of other polymer materials, the number will be very alarming. At present, in addition to a small amount of discarded plastic products to be recycled again, they should be treated by incineration, landfilling and pouring into the sea. Due to the very slow decomposition of such plastic products in nature (about 200 years), it is bound to cause serious pollution and inestimable damage to the ecological environment. To this end, people have adopted various methods to solve this problem, such as paper products
