Composting refers to the process bywhich biodegradable components are biologically decomposed under aerobic conditions by microorganisms (mainly bacteria and fungi). A Composting Chamber converts excreta and organics into Compost. Compost is a stable, inoffensive product that can be handled safely and used as a soil conditioner. This technology usually requires four main parts: 1) a reactor (storage chamber); 2) a ventilation unit to provide oxygen and allow gases (CO2, water vapour) to escape; 3) a leachate collection system ; and 4) an access door to remove the mature product.
None of the options were relevant for Composting chamber.
