Tratamento De Resíduos Da Avicultura De Postura Por Digestão Anaeróbia

Abstract: O tratamento de resíduos da avicultura de postura, por meio da digestão anaeróbia, consiste em alternativa sustentável para a geração de renda e de energia para o pequeno produtor rural e, ainda, para a disposição final deste material orgânico com alto potencial poluidor. Neste sentido, o objetivo deste trabalho foi comparar a eficiência da digestão anaeróbia dos resíduos de galinhas poedeiras e da coturnicultura, baseada na redução dos sólidos voláteis durante o bioprocesso. Para isso, a digestão anaeróbia fo… Show more

“…If, on the one hand, the factors and numbers presented earlier show economic motivation, on the other hand, they become worrying in environmental terms, in view of the consequent increase in the disposal of the quail waste resulting from the expansion of the coturniculture (Pinheiro et al, 2022), since, according to De Bona et al (2017, the intensive poultry production generates the waste from the activities, which should be treated in such a way as to minimize environmental impacts. For this reason, as impacts on the environment grow dramatically, there is a need to adopt mitigation measures and new technologies aimed at transforming waste into compounds to be absorbed by the biosphere, that is, going beyond sustainability.…”

“…In addition, the use of anaerobic digestion for the treatment of animal waste has been a viable and promising technology for biogas from confined animal production systems. In this perspective, Pinheiro et al (2022) point out that the treatment of laying bird waste in a rational, environmental and economic way, with the aim of achieving energy potential and reducing environmental impact, can be achieved through anaerobic digestion. In this sense, Capson-Tojo et al (2016) emphasize that anaerobic digestion can be understood as a biological process that happens in several stages of organic matter degradation, with the intention of producing biogas and digestate in environments without oxygen.…”
