Biodegradable Bags in Warwick, RI

Biodegradable bags are manufactured from materials that undergo biological degradation through the action of microorganisms — bacteria, fungi, and algae — breaking complex polymer chains into simpler compounds including water, CO2, and biomass. Unlike conventional plastics that persist in the environment for hundreds of years, biodegradable packaging materials break down within months to years under appropriate conditions, significantly reducing the environmental persistence of packaging waste.

Biodegradable Materials

• PLA (Polylactic Acid): Derived from fermented plant sugars (corn, sugarcane) — compostable in industrial composting facilities certified to ASTM D6400
• PBAT (Polybutylene Adipate Terephthalate): Petroleum-derived but certified biodegradable — often blended with PLA for improved flexibility
• TPS (Thermoplastic Starch): Derived from potato or corn starch — highly biodegradable but sensitive to moisture
• PHB/PHA (Polyhydroxyalkanoates): Bacterial fermentation-derived bioplastics — home compostable and marine biodegradable in some formulations
• Cellulose Film: Wood pulp-derived transparent film — biodegradable and compostable, used as NatureFlex or similar brands

Important Distinction: Biodegradable vs. Compostable

Biodegradable means a material will eventually break down biologically — but without a timeframe specification or conditions definition. Compostable materials meet specific standards (ASTM D6400, EN 13432) that define the timeframe and conditions under which biodegradation occurs. Brands making compostable claims should use certified compostable materials to avoid greenwashing liability under FTC Green Guides.
