How do biodegradable plastics work?

Can you explain how biodegradable plastics work?

Biodegradable plastics are designed to break down more quickly than traditional plastics. They decompose through the action of living organisms, usually microbes, which consume the material.

What materials are used to make biodegradable plastics?

Common materials include polylactic acid (PLA) made from corn starch, and polyhydroxyalkanoates (PHA) produced by bacteria. These materials are more environmentally friendly.

How long does it take for biodegradable plastics to decompose?

It varies, but biodegradable plastics can take anywhere from a few months to a couple of years to decompose, depending on environmental conditions.

Are biodegradable plastics better for the environment?

They can be better because they reduce plastic waste and pollution, but they still require proper disposal methods to be effective.

What happens if biodegradable plastics end up in a landfill?

In a landfill, biodegradable plastics may not decompose effectively due to lack of oxygen and light, which can lead to them persisting for a long time.
