Composting is the controlled aerobic (oxygen-requiring) decomposition of organic materials by microorganisms in a controlled condition. It reduces the volume and the mass of raw materials while transforming them into a valuable soil conditioner: compost. Mentions about the composting of bioplastics usually refer to industrial composting in a managed composting facility (Criteria defined in EN 13432).The main difference between industrial and home/garden composting is that temperatures in the industrial composting facilities are much higher and kept stable, whereas the temperature of a home compost are usually lower and less constant as well as being influenced by multiple other factors such as weather conditions. Home composting is a much slower process than industrial composting involving a comparatively smaller volume of waste. While a French norm has recently been developed, a Europe norm for home composting is yet to be developed.
