Aerobic Composting Composting is the managed process of breaking down organic material. Also, the amount of oxygen being incorporated matters– and of course, the temperature of the compost. Another method of treating municipal solid waste is composting, a biological process in which the organic portion of refuse is allowed to decompose under carefully controlled conditions. The process by which gardeners convert organic matter for use is called composting, and the usable material is referred to as compost. The purpose or methods chosen for composting greatly affects Factors affecting the composting process and acceptable ranges When organic wastes are broken down by microorganisms in a heat-generating environment, waste volume is reduced, many harmful organisms are destroyed, and a useful, potentially marketable, product is produced. Regardless of the method of aeration, the amount of oxygen supplied to the compost pile may differ from the amount of oxygen that is actually reaching the microbes. Commercial composting professionals often want to make their compost as quickly as possible, usually sacrificing the compost’s curing time.

After the composting process is complete, these nutrients, plus any additional nutrients available in organic materials, are released back into the compost as the microorganisms die.

Organic matter Release heat (Thermophilic state, which helps to destroy pathogens) Temp 55-60o c Organic matter compost (Mesophilic state ,Temp.

The Indian Indore methods enhance passive aeration slightly through a few turnings, thereby permitting aerobic decomposition and enabling production in a … Bacteria proliferate as simple food sources such as sugars, carbohydrates, proteins, and fats are consumed. This is where compost will meet the Process to Further Reduce Pathogens or PFRP, which is a heat treatment that involves turning the pile to insure all of the compost meets a minimum of 131 F for at least 3 days. • The first 2–6 weeks • Longer if the process is stagnant At this stage, fresh, raw compost has lots of readily available food for microbes.
