How is animal manure used as a source of energy?
Waste materials – ranging from animal manure for methane to wood chips for direct heat to waste vegetable oil for straight use or conversion to biodiesel – also have a positive energy and carbon balance. That is, more energy is derived from the fuel than is spent converting it.
How is biodiesel made from animal manure?
Waste materials – ranging from animal manure for methane to wood chips for direct heat to waste vegetable oil for straight use or conversion to biodiesel – also have a positive energy and carbon balance. That is, more energy is derived from the fuel than is spent converting it. Therefore, no net CO 2 is generated.
