Biosynthetics are fibres and a type of synthetic materials made from renewable resources instead of fossil fuels, that normal synthetic materials are made of. All biosynthetics are not biodegradable, but a part of the production, like growing crops such as sugar cane, corn, wheat and grass, can absorb carbon-emissions from the environment. Biosynthetics can often be recycled, however unfortunately many biodegradable fibres will be mixed with non-biodegradable fibers, these can usually not be seperated before recycling/composting. A concern about biosynthetics is the use of genetically modified corn as a source of raw material, and that land that could otherwise be used to grow food will be used to grow materials for clothing. We believe that biosynthetics are not yet developed well enough to be called sustainable materials.
