How long does it take for plastic waste materials to decompose?

The degradation time of plastic depends on the composition of the plastic, and it takes more than 100-200 years for ordinary plastics to degrade. Degradable plastics can degrade within months to years.

Now the environmentally friendly degradable plastic bags used in supermarkets are all starch-based degradable plastics, which degrade very quickly, and the substances produced after degradation will not pollute the environment, generally ranging from a few months to two or three years.

Biodegradable plastics made of PBAT materials can be completely degraded in 4 to 5 months.

PHA and PBAT plastic bags can degrade faster under the conditions of seawater and (25±3) ℃, and can be completely degraded in about 30-60 days.
