This document discusses biodiesel, an alternative fuel made from renewable sources like vegetable oils and waste cooking oil. It is produced through a process called transesterification and has several advantages over petroleum diesel, such as being less toxic, producing lower emissions, and providing an opportunity to decrease foreign oil dependence. The document proposes a pilot program to produce biodiesel using waste cooking oil and implement its use in the vehicles of the City of Fort Worth. A five-stage plan is outlined to eventually expand regional biodiesel production and use.
