From "Brown Grease" to Biofuel

Biodiesel fuel lowers our transportation costs, and reduces our carbon footprint. But it hasn’t become as popular as some might hope. Some alternative energy experts criticize its reliance on food supplies like corn or vegetable oils. They say, "Why sacrifice food to make fuel?"

But one new refinery in Nashua is avoiding that controversy by creating bio-fuel from something called "brown grease," and it’s hoping to turn that brown grease green, in more ways than one. Word of Mouth correspondent Sheryl Rich-Kern visited the Batchelder Biodiesel Refinery in Nashua, and brings us this story as part of our "next green thing" series.
