Invasion of the Grease Monster


Used vegetable oil can be recycled into non-toxic, renewable, biodegradable fuel called biodiesel.



How Biodiesel Is Made

Click to view full size - Biodiesel ProcessBiodiesel is made from organic oil sources such as vegetable oil, soybean oil, or cooking oil.

A fat or oil is reacted with an alcohol such as methanol and a catalyst such as sodium or potassium hydroxide. This produces glycerin and methyl esters, or biodiesel.

The basic steps are as follows:

  1. Filter source vegetable oil to remove solids
  2. Heat oil, and then mix in catalyst and methanol
  3. Allow oil to separate
  4. Remove glycerin layer
  5. Wash biodiesel, and then allow it to separate again for purification
  6. Remove water layer
  7. Store, allowing any traces of water to evaporate
  8. Put it in your tank and drive!

The biodiesel process is extremely efficient, even the "waste" products of this process are recovered and reused, recycled, or used for other things such as fertilizer.

Dallas School Buses Run On Biodiesel

fry oil to fuelRecycling your cooking oil helps get Dallas ISD students to school.

Dallas County Schools is one of the largest student transportation fleets in the U.S. and transports around 60,000 students every day. Now they are doing it using biodiesel that has been collected from restaurants, food manufacturers and residents across the metroplex. Biofuel reduces fuel costs and pollution while reducing the amount of oil waste products going to the landfill or even worse, down the drain.

Dallas County citizens are encouraged to take their used cooking oil to a Cease the Grease drop off location so it can be recycled into biodiesel and used to power Dallas County school buses. Use our Drop off location finder to find the nearest location to you.
