Since 1950s, human being had produced over 830 billion tons of plastic products. Used plastics are degraded in natural environment between 200 and 700 years and those buried plastics directly occupied a large amount of soil. Incineration treatment will produce toxic gas-diox-ins because of incomplete combustion and its pollutant discharged to the ocean will endanger marine animals’ survival. Excessive use of plastics and its improper treatment in the later stage will severely pollute the soil, air and water. Based on such severe environmental pollution, many countries actively promote regulation of limiting or prohibiting the use of disposable plastic products. Industrial organizations and enterprises positively implement plastic-recycling target and continuously innovate renewable bio-based material and biodegradable materials.
