If there is too little air in a compost pile because of compaction, anaerobic decomposition occurs, producing an odor like that of rotting eggs. Improving compost process efficiency by controlling aeration, temperature and pH. in this process, the ratio of carbon to other A compost pile can have too … “starters,” which they claim speed up the composting process. Turning the pile often will provide an ample amount of air and speed the composting process. Composting process is quite commonly used and results in production of a stable product - compost which depending upon its quality can be used as a low grade manure and soil conditioner.

Organic wastes are wastes that easily biodegradable. 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. Various process controls manage environmental factors—air, heat, moisture—to optimize the process. Doctoral dissertation.

The microbe-usable amount of the composting process and leading to foul odors. The Rapid Composting Method The author is Robert D. Raabe, Professor of Plant Pathology, Berkeley. This paper reviewed studies on the composting process of organic waste. ISSN 1652-6880, ISBN 91-576-6902-3 Biowaste composting is rapidly increasing, and many composting plants in Scandinavia have had problems with low pH during the process… Composting is a process in which organic substances are reduced from large volumes of rapidly decomposable materials to small volumes of materials which continue to decompose slowly. These organisms thrive by aeration, without the need for water or chemicals. The process results in conservation of natural resources and is an important processing method, especially in agricultural and horticultural areas.
