Although biodegradable plastic products currently account for only a small portion of the EU plastics market, the EU biodegradable plastics scale industrial capacity has increased from 230,000 tons per year in 2007 to 930,000 tons per year in 2011. Biodegradable plastics are widely recognized as an alternative solution to the global problem of waste plastics management, and continue to attract investment enthusiasm and high attention from the whole society.
The European Commission pointed out that the term “biodegradable†itself may cause misunderstandings by consumer users, such as biodegradable plastics, which may be interpreted as suitable for natural degradation of farm household compost. In fact, the vast majority of biodegradable plastics must be biodegraded under specific high temperature and humid conditions using specialized industrial composting infrastructure, ie it is not suitable for farm family composting, nor for a reasonable period of time. degradation. Strictly distinguishing the natural degradable and industrial degradation of plastic products families, has been put on the EU agenda, and actively guide consumer users to take appropriate post-treatment methods for end-of-life biodegradable plastic products. Member countries are required to strictly implement products with biodegradable labels, and can only be applied to products that are biodegradable in a short period of time under natural conditions. The European Commission requires member states to take seriously the oxide components used in biodegradable plastics, usually metal salts, residual treatment after biodegradation and micro-treatment after oxidation, pyrolysis, and ultra-ultraviolet (UV) light treatment. Disposal of plastic fragments.
Up to now, the environmental impact of micro-biodegradable plastic is still a lack of reliable data on the basis of science. At the very least, micro-plastic residual debris can eventually reach the ocean through various pathways, increasing the risk of marine animal and plant intake. Waste biodegradable plastics contain oxides while increasing the considerable additional cost of recycling and recycling waste plastics.
