What are the industrial composting drawbacks?

Some drawbacks in a composting operation may include odors, temperature abnormalities, and fly or mosquito problems. Odor problems, may result from odorous feedstock, excess nitrogen released in ammonia form, and odorous by-products (such as hydrogen sulfide gas) of anaerobic decomposition. Control these with proper storage or timely use of feedstock, sufficient carbon sources and bulking agents to control ammonia release, and appropriate moisture and aeration to ensure aerobic conditions. An acceptable temperature can be maintained by building piles or windrows of appropriate size, maintaining moisture content between 40% and 60%, and mixing properly. Insect problems are generally ociated with exposed wet feedstock or standing water on site. Timely mixing of feedstocks and good control of water from drainage, runoff, and leaching will limit opportunity for insect breeding.
