An Integrated Approach for Efficient Energy Recovery Production from Livestock and Agro-Industrial Wastes

The supply and food safety needs of the growing population, particularly in (peri) urban areas, promote the intensification, concentration, and specialization of human, agricultural, livestock, and agro-industrial activities. As a result, important quantities of waste and wastewater, with significant organic and nutrient loads, are generated and need to be managed properly in order to protect the soil quality and fertility, as well as to prevent water and air pollution. Among the models, processes, treatment, and recovery technologies, anaerobic digestion can be highlighted due to the production of biogas, a renewable energy source.
