Biodegradable waste can be used for composting or a resource for heat, electricity and fuel by means of incineration or anaerobic digestion.[6] Swiss Kompogas and the Danish AIKAN process are examples of anaerobic digestion of biodegradable waste.
Non biodegradable-Non-biodegradable materials do not breakdown naturally. But, that doesn’t mean they cannot be reused. The key difference here is that the process requires time, energy and expense. Glass and plastic can be reused to make other products, but the waste must first be separated by type of material and then processed into a usable substance.
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things using composting, aerobic digestion, anaerobic digestion or similar processes.
