SeaCo is a replacement biomaterial for single-use plastic products made from seaweed (agarophytes) polysaccharides, the material is compostable in 2 weeks in the average compost bin. The material can be used in place of most single-use plastic products, for example, PPE, biomedical tests and appliances, disposable cutlery, and containers.
