Anaerobic composting Anaerobic composting process takes place without the involvement of oxygen. %���� 8 0 obj This composting heap which has a passive areating tunnel in the center. endobj Very wet and nutrient rich materials such as kitchen waste or sewage sludge can cause problems during the composting process (clogging of the free air space, and therefore creation of anoxic zones and emission of bad odors). The need for oxygen and the production of heat are greatest during the early stages and then decrease as the process continues. <> Anaerobic Composting works best with nitrogen-rich materials as they are mainly wet, but almost any organic material can be processed in an anaerobic composter such as waste paper and cardboard, grass cuttings, left over food, animal slurries and manure, etc, or any other type of feedstock that has a particularly high water content.. 1.
