Removing such waste from the rest of the waste stream substantially reduces waste volumes for disposal and also allows biodegradable waste to be composted. 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 ...
First one places a solid waste sample in a container with microorganisms and soil, and then aerates the mixture. Over the course of several days, microorganisms digest the sample bit by bit and produce carbon dioxide – the resulting amount of CO 2 serves as an indicator of degradation. Biodegradability can also be measured by anaerobic ...
Treating biodegradable waste before it enters a landfill reduces global warming from fugitive methane; untreated waste breaks down anaerobically in a landfill, producing landfill gas that contains methane, a potent greenhouse gas. The methane produced in an anaerobic digester can be used as biogas. [64]
The biodegradable element of the waste stream is vitally important in the use of systems such as composting or anaerobic digestion. Waste characterization is a manual process carried beside waste management plants in a process that consists of taking 1 tone from a garbage truck, dividing the sample into 4 parts, mixing them, dividing again into ...
The waste management infrastructure currently recycles regular plastic waste, incinerates it, or places it in a landfill. Mixing biodegradable plastics into the regular waste infrastructure poses some dangers to the environment. [36] Thus, it is crucial to identify how to correctly decompose alternative plastic materials.
The following page contains articles linked to the management of biodegradable wastes. Biodegradable wastes are important as when landfilled they break down anaerobically to produce biogas . If uncaptured this escapes into the atmosphere and becomes a contributor to global warming .
