Answer:
Converting animal and plant waste into energy can be a triple-hitter: It not only helps reduce waste going to landfills or from being released as gas into the atmosphere, but saves energy and money. 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 CO2 is generated.
Animal Manure
Nature has always used anaerobic digestion – bacteria breaking down organic material in the absence of oxygen – to recycle waste. Modern anaerobic digester systems on livestock farms work on the same principle: The solids in manure are converted by bacteria into biogas, primarily methane, which can then be used to generate electricity.
