Introduction
Researchers at the University of Washington have developed a new type of bioplastic made from Spirulina, a blue-green cyanobacteria, aiming to create a more environmentally friendly and backyard compostable alternative to traditional plastics.
Details
- Bioplastic Composition: Made entirely from powdered Spirulina.
- Production Process: Utilizes heat and pressure, similar to conventional plastic manufacturing.
- Properties and Advantages:
- Bio-derived and biodegradable in backyard conditions.
- 10 times stronger and stiffer than previous spirulina bioplastics.
- Carbon-neutral or potentially carbon-negative due to Spirulina’s CO2 sequestration during growth.
- Fire-resistant, self-extinguishing upon exposure to fire.
- Challenges:
- Brittle nature and sensitivity to water.
- Ongoing research to address these issues and diversify applications.
Summary
This innovative spirulina-based bioplastic presents a sustainable alternative to conventional plastics, offering unique properties like strength, stiffness, fire resistance, and environmental friendliness. The researchers focus on improving its brittleness and water sensitivity to broaden its practical applications.
