Biotechnology Transforms Animal Waste to Human Wealth

A North Carolina State University scientist has developed a system called thermophilic anaerobic digestion, which converts animal waste into various useful products, including methane gas for fuel, liquid nutrients for aquaculture, and nutrient-rich feed additives for the poultry and livestock industries.

The thermophilic anaerobic digestion process involves enclosing animal waste in containers with heat-loving bacteria. The waste in the digester unit is heated to more than 115 degrees F. Bacteria in the digester then convert the waste into biogas, which can be used as fuel. The bacteria also destroy pathogens in the solid residue that remains. These by-products can then be processed as sanitary, nutrient-rich feed supplements.

The demonstration projects in North Carolina indicate that the thermal recyclers are very productive.

This simple method for processing animal waste, may someday lead to the productive use of the 500 million tons of poultry and livestock waste produced in the United States each year.

The National Institute of Science and Media keeps update information on the latest developments in the field of biotechnology and science. Distinguished writer, Joel Ball is at the fore front of all the publications of National Institute of Science and Media.
