The Green Science Alliance has been attempting to replace all petrochemical-derived products with natural biomass-derived chemicals. This time, Dr. Ryohei Mori has developed a 100% natural biomass biodegradable coating material based on PLA (polylactic acid).
PLA-based 100% natural biomass biodegradable coating material
Environmental problems caused by population explosion such as global warming, depletion of natural resources, water shortage and plastic pollution are becoming increasingly serious worldwide. In particular, the problem of microplastic
pollution is destroying nature, including the marine environment. Recently, it has been reported that nanoplastic pollution, which is smaller than microplastic pollution, is already present in our bodies.
Biodegradable plastics are one of the solutions that can alleviate this plastic pollution problem. One of the typical biodegradable plastics is PLA, a thermoplastic resin that is commonly used as a biodegradable plastic. It is not common for PLA to be dissolved in a liquid (solvent or water) and used as a coating or paint material. Some solvents can dissolve PLA, although these solvents are often toxic and harmful to humans and the environment.

In response, Dr. Ryohei Mori of Green Science Alliance Co., Ltd. has developed a 100% natural biomass biodegradable coating material based on PLA with a special grade of PLA. Solvents are one of the more environmentally friendly naturally derived materials and other additives are also naturally derived. This is a very rare product because PLA is often used as a plastic, and this PLA can be coated or painted. The Green Science Alliance also plans to apply color to make PLA-based color inks and coatings.
