Organic waste from livestock systems: Production of biogas and derivatives

Abstract:

The objective of this literature review is to evaluate the viability of organic waste from livestock systems with potential for the production of biogas and derivatives. The increase of the world population brings as consequence the imperative need to produce more food. And with it, the increase in livestock production itself that generates excreta that bring with it problems in both human and animal health, pollution to water tributaries and greenhouse gases. The proper treatment of these excreta in biodigesters can recycle nutrients (biol and biosol) and generate energy in the form of methane, promoting the sustainable development of producers and reducing the environmental impact.
