Abstract

Numerous unfit for human consumption animal byproducts are produced as a result of the ever-increasing demand for livestock production for food. As a result, the number of rendering plants that help turn animal waste into fat and protein flour is on the rise. Odors emitted from rendering processes can significantly impact air quality, causing nuisance for humans, especially when the plant is close to residential areas. The concentration of odor emission from thermal rendering operations, as determined by dynamic olfactometry, and the removal efficiency of the plant's three-stage water scrubber are the primary topics of this study. Due to their high odorant concentrations, three of the six process air stream emitters studied contributed the most to the odor. The elimination of odor nuisance by a 3-stage water scrubber revealed a removal efficiency of < 94%. This result suggested synergy between olfactory and sensorial methods of odour assessment and must be used to achieve satisfactory results.
