Greenbelt Resources funds ethanol feedstock study

By Greenbelt Resources Corp. | September 27, 2013

Greenbelt Resources Corp. and its wholly-owned subsidiary Diversified Ethanol Corp. have announced their investment in a research effort with California Polytechnic State University at San Luis Obispo focused on fermentation testing related to various ethanol production-related feedstocks. The focus of the study is on the efficacy of food waste and sweet potato fermentation for the production of fuel ethanol for commercial use. Testing, which began earlier this year, will conclude by the end of the year.

The study seeks to optimize three factors in biomass-based ethanol production that are critical to the scalability and adoption of the technology solutions provided by Greenbelt and Diversified: process temperature, application of various enzymes, and variations in fermentation processing. Batch ethanol yield is a key factor in the effort to scale down ethanol production to reach localized volume demands. Research parameters will report on the effect on yield from variances in temperature, pH levels, enzyme volumes and concentration, particle size, and batch volumes. The study will also compare separate hydrolysis (SHF) versus simultaneous saccharification (SSF).

"The funding from these two companies has been instrumental in the continuation of our research around waste-to-fuel conversion formulas," said Yarrow Nelson of the Department of Civil and Environmental Engineering and the principal investigator for the Cal Poly research team. "But more than the financial support, the engagement by the leadership from both companies has been impressive and adds value to the quality of our study."

"Tapping some of the brightest research minds right here in our backyard at Cal Poly gives us a tremendous advantage as we lead the global market with the first technology solution enabling localized small-scale waste-to-ethanol production," said Darren Eng, CEO of Greenbelt Resources. "The results targeted by our research team will help us continue to improve upon our cutting edge alternative fuel production system."
