This paper describes a new and environmentally friendly process for
developing biodiesel from commercial feather meal, a waste product of
the poultry industry. Currently, feather meal is used as an animal feed,
given its high protein content, and also as a fertilizer because of its
high nitrogen content. In this work, we have extracted fat from the
feather meal in boiling water (70 °C) and then transesterified the fat
into biodiesel using KOH and methanol; 7-11% biodiesel (on a dry basis)
is produced in this process. ASTM analysis of the prepared feather meal
biodiesel confirmed that the biodiesel is of good quality and comparable
to other biodiesels made from other common feedstocks. Given the amount
of feather meal produced by the poultry industry, it is estimated that
this process can create 150-200 million gallons of biodiesel in the
United States and 593.2 million gallons worldwide.
