24 Jul 2023 --- Researchers from the University of Washington (UW), US, have developed new bioplastics made from spirulina that they claim degrade in approximately three to four weeks – the same rate as a banana peel in a backyard compost bin. The team used heat and pressure to form the spirulina powder into various shapes – the same processing technique used to create conventional plastics. The material is also recyclable, which the researchers say may be a better end-of-life solution for the material than letting it biodegrade.
