Mexican scientists plan to build a pilot biodiesel plant that could be used to supply the public transit system in Mexico City, the National Autonomous University of Mexico, or UNAM, said.
The plant, which will be located at the RTP transit system's garage, is expected to provide 2,000 liters (528 gallons) per day of the fuel, the UNAM said in a statement.
The fuel will be produced from waste cooking oil from restaurants and hotels.
A School of Engineering lab will be responsible for sourcing and quality control for the first project of this type in Mexico, postgraduate researcher Alejandra Castro Gonzalez said.
The quality of the source oil and the biodiesel must be high to ensure the smooth operation of vehicles using it as fuel and avoid damaging engines, Castro said.
Use of biodiesel will help reduce emissions of pollutants, as well as recycling a product that is now often discarded, the researcher said.
"Some (establishments in Ciudad Universitaria) discard about 70 percent and others just 20 percent (of cooking oils), so we can deduce that there are shops that cook more healthy than others," Castro said.
The project is being funded by the Conacyt Mixed Fund and the Federal District's government. EFE
