Biodegradable waste can be used for composting or a resource for heat, electricity and fuel by means of incineration or anaerobic digestion. [7] Swiss Kompogas and the Danish AIKAN process are examples of anaerobic digestion of biodegradable waste. [8] [9] While incineration can recover the most energy, anaerobic digestion plants retain ...
The third and final study reviews European standardization of biodegradable and compostable material in the packaging industry, again using the terms separately. [43] The distinction between these terms is crucial because waste management confusion leads to improper disposal of materials by people on a daily basis. Biodegradation technology has ...
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection , transport , treatment , and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws , technologies, and economic ...
Green waste does not include things such as dried leaves, pine straw, or hay. Such materials are rich in carbon and considered "brown wastes," while green wastes contain high concentrations of nitrogen. Green waste can be used to increase the efficiency of many composting operations and can be added to soil to sustain local nutrient cycling.
MBT can alternatively process the waste to produce a high calorific fuel termed refuse derived fuel (RDF). RDF can be used in cement kilns or thermal combustion power plants and is generally made up from plastics and biodegradable organic waste. Systems which are configured to produce RDF include the Herhof and Ecodeco processes.
Brown waste is any biodegradable waste that is predominantly carbon based. The term includes such items as grass cuttings, dry leaves, twigs, hay, paper, sawdust, corn cobs, used livestock bedding, manure, animal waste, cardboard, pine needles or cones, etc. [1] Carbon is necessary for composting, which uses a combination of green waste and brown waste to promote the microbial processes ...
Biodrying is the process by which biodegradable waste is rapidly heated through initial stages of composting to remove moisture from a waste stream and hence reduce its overall weight. [1] In biodrying processes, the drying rates are augmented by biological heat in addition to forced aeration.
Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste. It is a bacterial process occurring ...
