PBAT:
Kamalpur Nagar Panchayat in Tripura has introduced compostable bags made from PBAT as a sustainable alternative to single-use plastic (SUP).
- PBAT (Polybutylene Adipate Terephthalate) is a biodegradable thermoplastic polymer used as an eco-friendly substitute for traditional plastics.
- It is a copolymer of adipic acid, 1,4-butanediol, and terephthalic acid and can be processed using conventional plastic manufacturing methods.
- PBAT is often blended with other biopolymers to enhance its mechanical and barrier properties.
- PBAT is 100% compostable – breaks down into water, CO₂, and biomass under industrial composting conditions within 180 days.
- Flexible and tough, making it ideal for bags, films, and packaging.
- It is moisture-resistant, chemically inert, and offers good barrier properties.
