Utilização do biogás no aquecimento ambiental de aviário.

Abstract

The Global Climate Change is one of the most important environmental problem in this century. This problem has increased with the intensification of greenhouse gas emissions (GGE), causing higher levels of gases such as methane (CH4) in the atmosphere. The major challenge in the regions with high concentration of animal production is reaching the energetic and environmental sustainability, as well as reducing the GGE. The energetic aspect is increasingly in importance in swine and poultry production. Recently, the search for alternative energies has been motivated by successive energetic crisis, global warning and high prices of petrol. The anaerobic digestion in biodigestors (biomethanization), consists in a complex mix of microorganisms that have the capability of convert organic materials, such as carbohydrates, lipids and proteins into methane and carbon dioxide. Probably, this process is the most economically feasible alternative to convert swine manure into thermal energy. Methane generated in biodigestor is a renewable source of energy that can substitute fossil fuels, such as buthane and wood for warming internal environments in poultry buildings.
