The development trend of degradable plastics
2021-01-27
1. According to different uses and environmental conditions, further deepening research, and through molecular design research, improving formulas, and developing punctual and controllable environmentally degradable plastics have become key research topics in many countries.
2. Actively research and develop high-efficiency and low-cost photosensitizers, oxidants, biological inducers, degradation accelerators, stabilizers, etc., to further improve on-time controllability, rapid degradability after use, and complete degradability.
3. Accelerate the development of biodegradable plastics or ordinary plastics and starch, cellulose or inorganic materials filling and blending or alloying technology, as well as completely biodegradable plastics and natural materials coating and lamination technology are hot spots.
4. Hydrolyzable plastics and edible plastics have attracted worldwide attention due to their special functions and uses, and have become another hot spot for environmentally compatible materials.
5. In order to accelerate the development of degradable plastics, countries are working to accelerate research and establish a unified definition, degradation mechanism, evaluation methods and standards for degradable plastics.
6. Explore and cultivate strains that can degrade ordinary plastics, so that the widely used ordinary plastics can be easily degraded after use to meet environmental protection requirements. At the same time, great attention is paid to cultivating biological plants that can produce polyester, so as to reduce the cost of biodegradable plastics and facilitate the promotion and application.
