Slaughterhouse Waste Composting

Amendment of Federal regulations concerning the management of bovine slaughterhouse waste prompted the investigation of cost-effective and regulatory compliant management options for these residuals. The slaughterhouse industry in British Columbia’s (BC) interior has been especially impacted by these changes as conventional management practices, primarily transportation to rendering facilities have become less economically feasible.

Composting of slaughterhouse waste was identified as a potential management option under the new regulatory changes. To further the industry’s understanding of composting, SYLVIS, in partnership with the BC Ministry of Agriculture and Lands, hosted a workshop and field day for industry representatives.  The workshop included presentations from the Canadian Food Inspection Agency, provincial regulators, and practitioners.

Prior to the event, a composting windrow composed of feedlot bedding, woodchips and slaughterhouse waste was established.  A tour of this demonstration compost windrow provided delegates with an opportunity to observe the composting of slaughterhouse waste first-hand. The establishment of a new windrow during the tour provided a demonstration of the construction of a slaughterhouse waste composting windrow.

SYLVIS participated in the siting, construction, and monitoring of the demonstration windrows. Thermocouples and datalogging equipment enabled the monitoring of composting conditions to ensure regulatory compliance. A leachate collection system was designed to measure leachate production and quality. The workshop and field day provided industry representatives with information to further investigate composting at their facilities.
