How do you turn something from yellow to green? Your art teacher would tell you to add blue, but American Kevin Newman would disagree. He would point to the pair of water heaters installed in his garage, which, with a hose and some chemicals, turn the fast-food by-product yellow grease into ‘green’ biodiesel.
Yellow grease is waste cooking oil from restaurant fast food fryers. It is a marginally valuable commodity, its use as an additive in animal feeds and cosmetics, but it can only be sold if it a certain standard. In the past, a lot of yellow grease went waste, to the that restaurants had to pay for it to be taken away. This was ideal for home-brewers like Kevin Newman, who picked up gallons of grease from their local fast food , and turned it to clean fuel at a cost of about $1 a gallon.
