<pre>Dear BEST, Please find below an article that discusses the conversion of waste cooking oil into biodiesel. Kumar Plocher, President of Yokayo Biofuels in California built his business on collecting used cooking oil and converting it to biodiesel. Presently, his company collects oil from more than 1,000 restaurants and produces nearly 500,0000 gallons of biodiesel each year, and has been collecting used oil since 2002. The article also briefly discusses the process of transesterification, which chemically reacts oils or fats with an alcohol to split the oil and recombine it with a methanol molecule to form methyl ester, or biodiesel.
