It is a fact not often considered in discussions of the sustainability of meat production:  a significant percentage of some animals is not used for meat. In the newest Meat MythCrusher video, produced by the North American Meat Institute (NAMI) and American Meat Science Association (AMSA), Dale Woerner, Ph.D., associate professor at Colorado State University, addresses the variety of products sourced from livestock in addition to meat, and how those products should be considered when discussing the sustainability of livestock production.

For cattle, on average 44 percent of the animal is not used for food and in pigs 30 percent of the animal goes to other sources. Other animal products include the hides, skins, hair, hoofs, horns, feet, heads, bones, blood, organs, glands, and intestines which can be used to make products including leather, medicines, cosmetics, pet food and soaps among many others.

“Rendering certainly adds to the sustainability of our industry in that we repurpose or reuse almost the entire animal for many things, said Dr. Woerner. “We’re able to reduce greenhouse gas emissions and that can be equated to 12 million cars per year off U.S. roadways.”

Dr. Woerner adds that these additional products are not commonly included in calculations of sustainability cited in the media.

“Often times in those discussions and the studies that have been conducted, the rendering and recycling of livestock and meat items is not included in those factors, but by utilizing rendering and recycling animal goods we are drastically improving livestock’s long shadow and improving the efficiency and sustainability in our business.”

The newest Meat MythCrusher video is the 45th  in the six year old series featuring interviews with meat scientists who bust some of the most common myths surrounding meat and poultry production and processing. Altogether the videos have been viewed more than 130,000 times. Other video topics include myths surrounding meat nutrition, antibiotic use in livestock, “Superbugs” in meat, Meatless Monday, hormone use in animals, ammonia in ground beefgrass-fed beef and more.

All of the videos as well as a new brochure covering the different meat myths addressed in them are available at
