What is Compostable Bioplastic?

The Plastic Persistence Problem

Conventional plastics can take hundreds to thousands of years to break down. They don't disappear — they fragment into microplastics that enter our food chain, water, and soil.

Biodegradable vs Compostable

The terms sound similar but mean very different things in practice.

Plastic waste with residue in soil — partial breakdown
Biodegradable

No timeframe guarantee

Breaks down eventually but no specific timeframe is required. May leave residue, including microplastic fragments.

The Science

Compostable plastics have the potential to break down within 90–180 days given sufficient humidity, oxygen, and microorganisms.
