In the study Mano Misra, Susanta Mohapatra, Narasimharao Kondamudi, and Jason Strull used chicken feather meal, which consists of processed chicken feathers, blood, and innards that have been processed at high temperatures with steam.
Currently this 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 described their 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.
