Tyson Foods and ConocoPhillips have a joint project that will use pork, beef and poultry byproduct fat to produce a diesel fuel. The focus is on finding ways to leverage Tyson’s protein chemistry and production acumen with ConocoPhillips’ processing and marketing know-how to introduce a renewable diesel fuel.

Springdale, Ark.-based Tyson will make the facility upgrades needed to pre-process animal fat from some of its North American rendering facilities. That’s expected to be in production later this year. ConocoPhillips, based in Houston, Texas, will take steps to start producing the fuel in several of its refineries.

The finished products will be renewable diesel fuel mixtures that meet all federal standards for ultra-low-sulfur diesel, officials say. Estimates are that the arrangement will eventually produce 175 million gallons annually as it ramps up through spring 2009.
