Got Feedstocks? Greenbelt Will Test Them For Feasibility

Feedstock Feasibility Testing Service Celebrates 3rd Anniversary

PASO ROBLES, CA – November 2, 2017 –The beauty of bioethanol is that it can be created from an amazing number of feedstocks of which many are considered waste – especially “food wastes”. Greenbelt Resources Corporation (OTC: GRCO) (Greenbelt) evaluates these feedstocks through its Feedstock Feasibility Testing Services and the results determine whether a cellulosic feedstock will succeed at commercial scale. The program is celebrating its three-year anniversary and has successfully tested many feedstocks. Greenbelt’s feasibility testing has found that trub, winery wastes, fruit around the nut, or the undesirable part of the fruit, all show great potential.

Greenbelt Chief Technology Officer Floyd Butterfield explains the three main issues in determining whether a feedstock is commercially viable:

  1. Can enough alcohol be extracted from the feedstock?
  2. How easily does it distill and is pre-treatment needed?
  3. Are contaminants present?

“All three of the questions can be answered positively,” says Butterfield, “but that still doesn’t necessarily mean the feedstock is the best choice. For example, your feedstock may produce high levels of ethanol, but if there is an unwanted contaminant and extra processes are needed to address it, then it impacts the economic viability of the feedstock.”

Another factor that improves a feedstock’s viability is what, if any, other byproducts other than bioethanol can be produced during the process. Feedstocks that produce bioproducts such as animal feed, edible dietary protein supplements, organic fertilizer and/or distilled water become economically stronger feedstocks at commercial scale.

Greenbelt has developed and manufactured a commercial scale waste-to-energy technology that annually produces 500,000 to 1 million gallons of bioethanol. Greenbelt CEO Darren Eng says Greenbelt’s systems can take full advantage of lower volume feedstocks such as the leftovers from juice manufacturing that would not otherwise be viable for a 30 million gallon plus biofuel plant.

“We do our research and testing at our facility in Paso Robles, California,” says Eng. “The plant is commercial scale so our Feedstock Feasibility Testing Services mimic the feedstock in an operation of 1 million gallons of bioethanol per year. For example, testing viability at commercial scale enables our clients to know, without a doubt, that if we declare a feedstock viable it will perform as expected.”
