Application of biodegradable plastics
2021-01-27
Because of its good degradability, biodegradable plastics are mainly used as food soft and hard packaging materials, which is also its biggest application field at this stage.
The main target markets for biodegradable plastics are plastic packaging films, agricultural films, disposable plastic bags and disposable plastic tableware. Compared with traditional plastic packaging materials, the cost of new degradable materials is slightly higher. However, with the increasing awareness of environmental protection, people are willing to use new degradable materials with a higher price to protect the environment. The increased awareness of environmental protection has brought huge development opportunities to the biodegradable new material industry. With the development of China’s economy, the successful hosting of the Olympics, World Expos and other large-scale events that shocked the world, the need for the protection of various world cultural heritage and national scenic spots, the environmental pollution caused by plastics has become more and more important. List the treatment of white pollution as one of the key tasks.
Developed countries and regions such as Europe, the United States, and Japan have successively formulated and promulgated relevant laws and regulations to restrict the use of non-degradable plastics through measures such as partial prohibition, restriction, mandatory collection, and collection of pollution taxes, and vigorously develop new biodegradable materials to protect the environment , Protect the soil. Among them, France issued a policy in 2005 that all disposable plastic bags that can be carried must be biodegradable after 2010.
At the same time, China has successively introduced a number of policies to encourage the application and promotion of biodegradable plastics. In 2004, the National People’s Congress passed the “Renewable Energy Law (Draft)” and “Solid Waste Law (Revision)” to encourage the use of renewable biomass energy and the promotion and application of degradable plastics; in 2005, the National Development and Reform Commission’s No. 40 document clearly encouraged The use and promotion of biodegradable plastics; In 2006, the National Development and Reform Commission launched a special fund project on the promotion of the development of biomass biodegradable materials; the "Definition, Classification, Labeling and Degradability Requirements for Degradable Plastics" implemented on January 1, 2007 were obtained The mutual recognition of Europe, the United States, Japan and other countries has facilitated the export of Chinese enterprises.
