Spirulina powder used for bioplastics (IMAGE) University of Washington Caption A team led by researchers at the University of Washington has developed new bioplastics that degrade on the same timescale as a banana peel in a backyard compost bin. These bioplastics are made from powdered blue-green cyanobacteria cells, otherwise known as spirulina (green powder shown here in the container).
