Can biodegradable plastics only be composted?
Q: Can biodegradable plastics only be composted?
Sanleplastics Eco Packaging: Not necessarily.
Biodegradable plastics can be biodegraded under composting conditions, in other conditions such as anaerobic digestion devices, and in natural environments such as soil, seawater, etc., but the specific structure of the plastic, the formula of the products and the environmental conditions of degradation are related. It is wrong to say that biodegradable plastics can only be composted.
For example, PHA and PBAT materials are easy to biodegrade under the conditions of seawater, soil and composting, while PLA is easy to biodegrade under the conditions of composting, and the degradation cycle or speed of seawater and soil is relatively slow
Q: Can biodegradable plastics be completely degraded in anaerobic digestion devices?
Sanleplastics Eco Packaging:
The main reason why biodegradable plastics can be degraded by microorganisms is that their chemical structure is different from that of traditional plastics. At present, most biodegradable materials can be degraded by microorganisms in anaerobic digestion devices.
