What will the fuel of the future look like and where will it come from? Anything & Everywhere...
"There is no one silver bullet," Van Groll said in a press release. "The silver bullets are already out there — taking waste streams and turning them into profit centers."
Prepare for a variety of fuels from many sources, says Wisconsin entrepreneur Joe Van Groll whose start-up renewable energy company produces both ethanol and bio-diesel without a single corn kernel or soybean in sight. The Grand Meadow Energy LLC near Stratford trucks in waste from surrounding cheese plants and raw canola oil from a nearby farm.
Van Groll bought the Grand Meadow Coop cheese plant when it closed more than three years ago, converted it and with $29,000 from the state's Agricultural Development and Diversification grant program, began testing what is now a trade secret. Today, customers buy a license to use the yeast-based technology he developed with help from the grant.
As concerns about the environmental and societal impact of corn-based ethanol rise, he lists the advantages of his method. "I don't use energy; I put it back on the grid. I don't slurp up water; I purify and recycle it. I don't push up food costs; I dispose of waste," he said.
Van Groll is a 13-year veteran of the state's cheese industry, and his process focuses on permeate, a by-product of cheese making. But Van Groll says the technology can be used on a variety of waste streams and he sees no end in sight to its application. His technology now turns what he refers to as "a messy problem" into a profit center for cheese plants. He buys permeate, blends it with a customized yeast culture, and produces pure alcohol ethanol. He does so at about a quarter of the cost of producing corn-based ethanol.
Two months ago, he began blending the ethanol with raw canola oil to make biodiesel. He uses the biodiesel to power a generator that produces electricity for his plant and plans to sell excess energy back to the power company. Producing two renewable fuels gives him the option of choosing which market is offering the best return. He also sells dried yeast, a byproduct of the process, for livestock feed.
