Getting to know your feedstocks

Article Abstract:

Composting facility operators should be knowledgeable on the attributes of their feedstocks in order to ensure success in the composting process and avoid problems. An operator who is knowledgeable on feedstocks will be able to formulate a successful combination of recipe and mix, thereby avoiding problems such as odor. Composting is both an art and a science. Composting as a science involves analyses of factors such as moisture content, carbon-nitrogen ratio, bulk density and pH.

Can composting BMPs reduce air emissions?

Article Abstract:

The California Integrated Waste Management Board (CIWMB) investigated the effect of management practices on air emissions from green waste composting. The results show that ammonia appears to be a non-issue with composting of typical green waste feedstock and that simple management practices can affect the rate, and probably the amount, of volatile organic compounds (VOC) emitted during green waste composting.
