Caracterização da cama de aviário de peru e potencialidade de produção de biogás

Abstract

Brazilian poultry industry is today one of the largest producers and exporters of turkey meat in the world and, along with this large production, there is a large generation of turkey poultry litter, especially in the state of Paraná, parents. The main destination given to this residue is its application to the soil in the form of fertilizer, thus, the constant search for new forms of management that may cause less impact to the environment arises. An alternative still little studied is the use of the bed of turkey for the production of biogas, through anaerobic biodigestion. If it proves viable it can become an attractive alternative both environmentally and economically. The biodigestion process promotes the conversion of organic matter to biogas, and the producer, through the use of biogas, can generate energy to meet the demands of his property, besides being able to generate an extra income through the commercialization of the biofertilizer produced. In this sense, the physical-chemical analyzes of three aviaries at the same production stage were carried out in three distinct properties located in the southwest of Paraná. With the results obtained, we identified different values, but close to those found by other authors, indicating an attractive potential of biogas production through the use of turkey litter. Through calculations to estimate the volume of biogas produced per batch, it was possible to identify a significant difference between poultry litter bed and turkey poultry litter, with turkey litter being a much larger production of biogas, this result may indicate a large production potential in the activity, contributed to the development of new energy production techniques.
