Biomass is one of the largest sources of energy available in agribusiness activities. Anaerobic biological degradation of organic matter, present in swine manure, produces a gaseous mixture of methane (CH4) and carbon dioxide (CO2).Anaerobic biodigestion is one of the most effective methods for the treatment of manure, obtaining as biogas products; Substitute for some fuels; And biofertilizer; Rich in nutrients and applied in agriculture.The conceptual simplicity of biodigestors does not bring light, the great complexity of chemical and physical processes. One of the main reasons for this complexity is the expressive amount of variables that must be monitored to guarantee better efficiency of these equipments. Among these variables, the values of biomass temperature, amount of gas generated, pH, residence time, among others, stand out.Aspects related to the Logistics of transport and storage of biomass to Process Control methods, plus Cultural aspects, Professional Training, Creation of public policies, Maintenance of biodigesters, are challenges in the application of biodigestion for energy generation from waste Pigs on an agroindustrial scale.The objective of this article is to analyze some factors that represent challenges to the application of biodigestion process for energy generation from swine waste on an agroindustrial scale, thus contributing to important reflection on the design and installation of biodigesters in agroindustrial activities.
