Electricity Production from Swine Manure: A Case Study from Mato Grosso, Brazil

The mode of disposal of waste and effluent from swine breeding constitutes an important practice for environmental compliance of farms. For the need to produce quality and sustainability deploy many ranchers have sought treatment systems process waste from pig farming. Brazil has been increasingly investing in research and implementation of techniques for treating these wastes. Thus, this paper aimed to present the advantages of manure treatment and utilization of animal by-products. The case study refers to a Cooperative Farming of Nova Mutum, MT. The farm currently contains more than 23,000 pigs and waste generated by this process, in addition to producing electricity, are used as biofertilizers in irrigation Eucalyptus after being treated in the digesters. Through empirical calculations it was found that the average biogas is 2,438 m³ per day, with a calorific value greater than 2,000 kWh / day or 60,000 kWh / month, number higher than 22,000 kWh / month currently generated, so the cooperative can increase the capacity of your generator if you want to produce more energy. This requires further study of the efficiency of the treatment and the quantity and quality of effluent produced.
