Chemical Industry Research Report Week 23: Biodegradable plastics

Biodegradable plastics-the next generation of the plastics industry

Biodegradable plastics refer to plastics that are degraded by the action of microorganisms under natural conditions or under specific conditions, and eventually completely degraded into carbon dioxide, water, methane, mineralized inorganic salts and new substances. Like traditional plastics, biodegradable plastics have good mechanical properties, impact properties and heat resistance, good thermal stability and water resistance. Unlike traditional plastics, biodegradable plastics are modified by filling starch or by natural high The molecules are formed by polymerization, so they have good degradability and achieve true environmental protection. They can be widely used in construction, packaging materials, textile fabrics, agriculture, medicine and other fields.

Taking advantage of the policy to shift the demands

At present, countries including the European Union, the United States, Japan and India are gradually promoting the use of biodegradable plastics to replace traditional universal plastics. my country has also started to ban non-degradable plastic bags and promote alternative products such as degradable shopping bags. On January 16, 2020, the National Development and Reform Commission and the Ministry of Ecology and Environment issued a new version of the plastic restriction order, clearly proposing the use of non-degradable plastic bags in different steps and areas, and promoting and applying alternatives such as degradable shopping bags and packaging films. product. The demand for biodegradable plastics is mainly concentrated in Western Europe and North America, and the output in China is also increasing rapidly. Currently, Western Europe, America and China are the main biodegradable plastic consumption regions, accounting for 55.0%, 19.0% and 12.0% respectively. In 2018, the global demand for biodegradable plastics was 360,000 tons, and the average annual compound growth rate from 2014 to 2018 was 4.9%, and the annual growth rate remained stable. From 2014 to 2018, the average annual compound growth rate of China's demand for biodegradable plastics was 13.8%.

In 2018, China's demand for biodegradable plastics was about 42,000 tons. In the future, with the increasing domestic emphasis on environmental protection and the promulgation of relevant laws and regulations, the development prospects of biodegradable plastics are worth looking forward to.
