Manure
The animals that provide the raw material for meat and dairy production create an enormous amount of manure. For example, one dairy cow can produce up to 120 lbs of manure each day. Traditionally, this manure has been used as a cheap form of fertilizer and spread on fields all across the nation. The regulatory agencies have begun to be concerned about the continued use of manure as a fertilizer, both from a public health perspective and as a carbon source contributing to global warming. There are a variety of technologies currently being developed to deal with manure in an environmentally sound manner, including the extraction of methane for use as a fuel and composting for safer fertilizer.
The ABVRS Technology converts manure into a burnable fuel source with a BTU value of approximately 7,500 BTU per pound. This is comparable with high-quality wood chips.
