The process of biodegradation under aerobic conditions within 6-12 weeks is called composting. Composting of industrial products usually takes place in a controlled conditions (e.g. temperature, humidity, aeration) are given . Microbes, like bacteria or fungi and their enzymes, are able to “digest” the chain structure of compostable polymers as a nutrition source . The final elements are water, carbon dioxide CO2 and a little biomass.
The speed of biodegradation depends on the temperature (50-70°C are typical for a industrial composting process), humidity (water is required for the process), microbes. In industrial composting facilities, all those requirements are given and certified compostable plastic products are converted into CO2, water and biomass within 6 to 12 weeks. While for home compost in some food supply industry, supermarkets or at home, biodegradation occurs at a very low speed in comparison to industrial composting. So Bio-bins are suggested to be used to for collecting and separating different waste, and treated in a composting plants to help accelerate the process and make it more efficient.
