Disposal of dead farm animals has seen changes in the past few decades. Formally a farmer would get paid to have his dead animals picked up because there was value in the by products. Now a farmer must pay to have dead animals removed from the farm because of prion-related diseases that have almost eliminated the market for bone meal and meat products of dead animals. Many farmers have turned to cremation or composting. This study looks at the environmental impacts of on farm disposal of dead stock. Multiple cremation sights were tested for several contaiminets using ta consistent methodology. For contaminants that have provincial or federal emission guidelines or limits, the emissions from the units were typically close to or do better than the standards when a secondary chamber was installed that had sufficient temperature and residence time. Insufficient time and temperature and poorly designed facilities were found to have increased toxic contaminants in the stack discharge.
