3.1. Technical feasibility
3.1.1. Waste cooking oil-to-biodiesel Recycling waste cooking oil for biodiesel production has beenืadopted by several universities in the US
The waste cooking oil-to-biodiesel option was initiated on a pilot scale at UC several years ago. For the pilot-scale system, waste cooking oil is collected from campus dining facilities and made into biodiesel in a 189 L (50-gal) batch reaction system. Biodiesel is made by the transesterification reaction between waste cooking oil and methanol with NaOH as the catalyst
