Some tips on the biodegradable materials
1. What are the biodegradable materials?
Biodegradable materials include biodegradable natural polymer materials such as cellulose, starch, paper, etc., as well as biodegradable plastics obtained by biosynthesis or chemical synthesis.
2. What types of biodegradable plastics are there?
According to the raw material source of biodegradable materials, they can be divided into bio-based biodegradable plastics and petrochemical-based biodegradable plastics.
Biodegradable plastics are mainly divided into three categories: the first category is plastics directly processed from natural materials. The second category is polymers obtained by the joint participation of microbial fermentation and chemical synthesis. The third category is polymers directly synthesized by microorganisms.
Petrochemical-based biodegradable plastics refer to plastics obtained by polymerizing petrochemical monomers by chemical synthesis.
3. What is the compostable biodegradable plastic?
Composting is an aerobic treatment method to produce compost.
4. Biodegradable plastics can only be composted?
Biodegradable plastics can be biodegraded under composting conditions, can also be biodegraded under other conditions such as anaerobic digestion equipment, and can be biodegraded under natural environments such as soil and seawater, but they are closely related to the chemical structure of plastics.
5. Under natural conditions, how long does the biodegradable plastic degrade?
The actual degradation time is related to natural conditions and the structure and formulation of the plastic.
