Biomass to sugar Plans are underway to build a commercial-scale sugar-production facility that uses a novel process for converting corn stover into high-purity glucose. The 95%-pure glucose syrup produced there will be used as a raw material in the production of bio-based chemicals. The plant, to be located in Sarnia, Ont., will be owned and operated by Comet Biorefining (London, Ont.; www.cometbiorefining.com), and will produce 60 million pounds per year of glucose when it comes online in 2018. To convert corn stover to glucose at low cost, Comet’s technology focuses on separating the three components of biomass (cellulose, hemicellulose and lignin) and producing highly reactive cellulose. The company has developed a proprietary, two-stage activation process that is used to convert reactive cellulose into glucose at significantly lower enzyme loading than traditional processes, Comet says. The highly reactive cellulose generated by the activation process requires less post-processing than comparative chemical approaches, Comet adds, which lowers production costs. The Comet technology also requires a smaller facility footprint than related technologies, which lowers capital costs and helps reduce feedstock transportation costs,…
