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 by composting, aerobic digestion, anaerobic digestion or similar processes. In waste management, it also includes some inorganic materials which can be decomposed by bacteria. Such materials include gypsum and its products such as plasterboard and other simple organic sulfates which can decompose to yield hydrogen sulphide in anaerobic land-fill conditions.

"Transformer" aerobic digestion method, a system for treating biodegradable waste material through aerobic degradation
ActiveUS20060105447A1Convenient and cost-effectiveCost-effective and convenient processBio-organic fraction processingSolid waste disposalLiquid wasteGreen waste
This method facilitates the cost effective treatment of liquid and solid waste in a landfill or composting facility. The ability to distribute the oxygen to the waste and remove the spent waste is the key to the process. The process can digest a megafill or treat massive green waste pile. Waste moisture content is increased, eliminating fires and removing a major constraining factor to degradation. Large quantities of liquid are oxygen-supplemented (therefore treated) and are added directly into the MSW or compost to maintain aerobic degradation. Oxygen is the limiting factor; water is the distribution method. Temperature increases with the availability of oxygen. The bacteria break down the solid and liquid waste. The material is available for cover or agricultural uses. Facility space is reused, odors are minimized, and environmental risk is minimized. Leachate is treated to the needs of the facility, which can be anywhere between total treatment and pretreatment.
