BioPBS biodegradable co-polyester by Mitsubishi
BioPBS polybutylene succinate (PBS) produced in a joint venture between Mitsubishi Chemical Company and PTT Global Chemical Public Company. This grade of biodegradable co-polyester is derived from biomass, such as sugarcane and cassava, and decomposes into water and CO2 with the microorganism under the soil in ambient conditions (30 degC) – it is suitable for home composting and doesn’t require any specialised facilities. PBS has relatively good heat resistance compared to other biodegradable plastics and can be converted into a fibre. It is applied as a coating to paper, such as for disposable coffee cups, as an injection moulding resin and flexible packaging. Image Mitsubishi.
