Biodiesel from Chicken Feathers

chickenFrom the guys who brought you biodiesel brewed from coffee grounds (see my post from Dec. 11, 2008), now they’ve come up with a process to turn the 11 billion pounds of poultry waste produced in the U.S. each year into the green fuel.

Science Daily has details of the process from the researchers at the University of Nevada-Reno:

In the study Mano Misra, Susanta Mohapatra, Narasimharao Kondamudi, and Jason Strull note that chicken feather meal consists of processed chicken feathers, blood, and innards that have been processed at high temperatures with steam. Currently feather meal is used as animal feed and fertilizer because of its high protein and nitrogen content. With as much as 12 percent fat content, feather meal has potential as an alternative, nonfood feedstock for the production of biofuel, the report says.

The researchers describe a new process for extracting fat from chicken feather meal using boiling water and processing it into biodiesel. Given the amount of feather meal generated by the poultry industry each year, they estimate this process could create 153 million gallons of biodiesel annually in the U.S. and 593 million gallons worldwide. In addition, they note that removal of fat content from feather meal results in both a higher-grade animal feed and a better nitrogen source for fertilizer applications.
