UW researchers create biodegradable plastics from cyanobacteria
A team of researchers at the University of Washington has developed new bioplastics made exclusively out of powdered spirulina, a blue-green cyanobacteria.
Unlike the majority of current bio-based plastics, which only decompose in commercial composting facilities, the spirulina-based material breaks down easily and can be composted in backyard bins. The new bioplastics share the same mechanical properties as single-use, petroleum-based plastics and are recyclable. However, the material remains brittle and sensitive to water.
While these spirulina bioplastics mark a success in creating an environmentally friendly alternative to traditional petroleum plastics, more testing must be completed before this alternative can be fully scaled up for commercial use.
