In the past two years, as low-carbon, energy-saving, and environmental protection have gradually become the main theme of social development, plant plastics made from sugar cane or the like have become popular. Some scientists predict that plant plastics are expected to completely replace petrochemical plastics in the next five years.
Chang Yuzhi, a researcher in the chemical industry of China Investment Advisors, pointed out that because the main components of petroleum plastics are mainly polyethylene or polystyrene, they are more difficult to degrade under natural conditions and are likely to cause environmental pollution. If burned directly, carcinogens will be generated during the combustion process, causing damage to human health. In the nature, plant plastics can be decomposed into water and carbon dioxide by microorganisms. It meets the requirements of environmental protection and is favored by people.
According to the “Investment Analysis and Prospect Forecast Report of China Plastics Industry 2010-2015†released by the China Investment Advisor, plant plastic is one of biodegradable plastics, mainly made of natural biomaterials such as corn or sugarcane. In recent years, vegetable plastics have been used in agricultural plastic films, fast food boxes, some electrical products, packaging materials, and clothing.
Chang Yongzhi also pointed out that although the use of plant plastics will not exert great pressure on the environment, it is more expensive than petroleum plastics or natural gas plastics in terms of manufacturing costs, and it is easily deformed when the temperature reaches 60°C or more. Therefore, at present, plant plastics have not been widely applied. However, from the long-term development trend, as people's awareness of environmental protection increases, plant plastics will gradually become popular.
Zhang Yanlin, research director of China Investment Consulting Co., Ltd., also pointed out that because petroleum plastics are difficult to degrade, it is not conducive to the ecological balance of nature. At present, six types of bioplastics have been developed in the world. Most of the raw materials of these bioplastics come from starch, cellulose and other substances in plants, and are easily degraded in nature. In the future, with the continuous development of technology and high production costs, bioplastics will gradually replace petrochemical plastics.
