Composting is a managed process that controls the biologicaldecomposition and transformation of biodegradable materials intoa humus-like substance called compost. The controlled biooxida-tion process proceeds through mesophilic and thermophilic phasesand results in the production of carbon dioxide, water, mineralsand stabilized organic matter (compost or humus). Another benefitof this process is that the heat produced can result in destruction ofpathogens that may be present in the waste stream. For mostoperations, including plastic biodegradation, a combination ofsludge and solid waste provides the best operation.
