Study of poultry carcass biodegradation through the Composting process in closed discontinuous digesters

ABSTRACT The study on poultry carcasses’ biodegradation through composting in closed discontinuous digesters enabled the evaluation of composting as an alternative for the treatment of solid waste generated on farms. The study began with the characterization of the waste that would be used in the process and went through the analysis and monitoring of the identified parameters to evaluate the composting process inside the digester. The composting was found satisfactory at the end of the process, and all carcasses were totally degraded and did not present any environmental risks.

摘要 本研究针对封闭式间歇式消化池内堆肥法降解家禽胴体展开研究，旨在评估堆肥技术作为养殖场固体废弃物处理替代方案的可行性。研究首先对实验所用废弃物开展理化特性表征，随后通过对选定参数的分析与监测，对消化池内的堆肥过程进行评估。实验结束后，堆肥过程效果令人满意，所有家禽胴体均完全降解，未产生任何环境风险。
