Heat, oxygen, moisture, are organic material are needed to facilitate this breakdown, and allow natural organisms called microbes to transform the waste into useful garden fertilizer. Organic material in the form of SUN-MAR peat mix is added manually. This provides an excellent form of organic carbon which is biologically active, absorbent, entraps oxygen, and speeds the composting process. Peat moss may be used as an acceptable substitute. This Bio-drum is uniquely able to provide a warm, moist, oxygen rich environment which allows fast, odorless, aerobic microbes to degrade the waste and toilet paper back to its basic minerals.
Organic carbon is converted to carbon dioxide and hydrogen to water vapor.
This revolutionary three chamber approach proved so successful, that we were able to double the composting speeds of the old single chamber units with mechanical mixers. All other units work on the same three chamber principle first developed by SUN-MAR in 1979. Waste enters the composting drum through an entry port located in the top of the Bio-drum. More frequent rotation of the drum is not recommended. The Bio-drum is fitted with a door which closes automatically to keep the waste inside as the drum rotates.
