Biodigestores: alternativa energética na otimização da produção agrícola

Abstract

This work aims to demonstrate the feasibility of deploying a biodigestion system on properties of the pampas of Rio Grande do Sul. Cutting cattle in this region has always been activity of great importance, because it functioned as a means of ensuring the survival of the local producers. Over the years the production of milk was added to existing culture that of the production of cattle, making both activities very well performed by some properties in the region. In parallel the milk production is the production of large amounts of manure, which will serve as a source of energy and will be the target of our research and technical development. In order to transform this manure produced in biogas, was made a survey of properties with potential for the installation of a system of biodigestion, evaluate a property that has ability to use abio-digester. For this we tried to ascertain the use of biogas as a renewable energy source, which through its burns in a motor/generator set would make the production of electric energy to power the property. If the electric energy generated is higher than the defendant by residence seeking leverage as distributed generation, injectingthe surplus on the dealership network providing service, and may use later thisbalance without cost. Because it is a considerable investment makes economic analysis in a horizon of 20 years.
