Natural Rendering Video

Captures a Blue Ribbon

for immediate release

October  2003


ITHACAAn important new video entitled Natural Rendering: Composting Livestock Mortality and Butcher Waste was awarded a blue ribbon in the 2003 ASAE Educational Aids Competition. The award was announced at the ASAE (American Society of Agricultural Engineers) annual meeting last July.


Natural Rendering: Composting Livestock Mortality and Butcher Waste, NRAES–163 ($19.00 plus S&H/sales tax, 20 minutes, 2002) was produced by Jean Bonhotal of the Cornell Waste Management Institute, Cornell University, and directed by Insights International, Inc., Ithaca, NY.  It was funded in part by Cornell Cooperative Extension; Empire State Development, Environmental Services Unit, Environmental Investment Program; North Country Agricultural Development Project; and American Association of Meat Producers. 


This 20-minute video takes a look at livestock mortality and butcher residual composting—an effective, economical, and environmentally sound alternative when rendering services are unavailable. Operator interviews at six on-farm livestock composting operations reveal how mortality composting can be implemented without having to purchase additional farm equipment. An added benefit is that the composting process reduces odors and pathogens.


From an economic perspective, composting provides a desperately needed option for livestock producers and butchers, faced with the high cost of disposal, to reduce their overhead. In 2002, disposal costs ranged up to $70 per cow, $200 per horse, $60 per pig, and $20 per barrel of butcher residuals. Due to the fluctuation in prices of hides, tallow, meat, and other products, many small rendering operations have been forced to close, while others have been forced to charge for pickup. Farmers and butchers in an increasing number of areas may not have access to these services at all.


This video will be useful to dairy farmers, livestock producers, poultry farmers, butchers, agriculture advisors, extension educators, and others.
