Compostable materials: Compostable materials can be biodegraded under the special conditions of high temperature soil, and usually need to be degraded in industrial compost.
Biodegradable or compostable, due to biodegradation, it is converted into water and carbon dioxide, and disappears from the environment to achieve a true environmental protection effect.
Biodegradable material: The organic matter in the biodegradable material is completely or partially converted into water, carbon dioxide / methane, energy and the biochemical process of new biomass under the action of microorganisms.
Degradable materials: The polymers in the degradable materials cause partial or complete damage due to ultraviolet radiation, oxidative corrosion, and biological corrosion, which means changes in performance, discoloration, cracking, and fragmentation.
PE material: PE (polyethylene) is cracked in petroleum to obtain ethylene monomer, which is then polymerized by chemical reaction such as polymerization. Polyethylene is a polymer polymerized by ethylene monomer, which is a non-renewable resource. Its advantage is low production cost. The performance of the product is stable, and its shortcoming is that the degradation time is hundreds of years, and plenty of toxic gas comes from plastic combustion, which causes great environmental pollution.
When purchasing biodegradable or compostable products, you need to check whether the material has the plastic bag mark specified by the state, and judge the production raw materials according to the mark. The commonly used biodegradable or compostable raw materials are PLA and PBAT. The biodegradable bag can be degraded into water and carbon dioxide in 180 days under the conditions of nature and soil or industrial compost. It belongs to the organic cycle and is harmless to the human body and the natural environment.
Bio-based plastics and biodegradable plastics are new materials that are environmentally friendly and sustainable alternatives to traditional plastics that currentl
