EPC also plans to install digesters at Swift & Company's beef processing plant in Grand Island, Nebraska. Meanwhile, the University of California, Davis claims to have developed an improved anaerobic digester, which produces both methane and hydrogen gas. The university is fueling the digester with eight tons per week of food scraps produced at local restaurants.
