Today, the Environmental Protection Agency (EPA) released its proposed Renewable Fuel Standard (RFS) renewable volume obligations (RVOs) for 2018. The agency proposed a total renewable fuel volume of 19.24 billion gallons (BG), of which 4.24 BG is advanced biofuel, including 238 million gallons of cellulosic biofuel. That leaves a 15 BG requirement for conventional renewable […]
Not long ago, United Airlines made history by becoming the first U.S. airline to begin use of commercial-scale volumes of sustainable aviation biofuel for regularly scheduled flights with the departure of United Flight 708 from Los Angeles International Airport. United has agreed to purchase up to 15 million gallons of sustainable biofuel from AltAir Paramount over a […]
Sylvatex has the potential to be a breakout star. One application of its technology splash blends a fuel additive called MicroX into diesel or biodiesel, at blend rates expected to be around 10 percent (although it can blend above 40%). In the additive is an low-cost oxygenate, it’s nano-scale encapsulated ethanol, and Sylvatex’s technology does […]
Verdezyne is a privately held industrial biotechnology company that is developing and commercializing novel genetically engineered microorganisms for use as “factories” to manufacture renewable chemicals. Verdezyne’s unique microorganisms permit greener, cleaner and more cost effective production of chemicals compared with traditional methods. The Company is commercializing its technology through partnerships with leading chemical manufacturers. Verdezyne […]
A recent DOE project with MicroBio Engineering had the primary objective of a detailed techno-economic and life cycle assessment for a coal-fired power plant with two microalgae CO2 utilization and mitigation options. First, biogas production to replace coal for maximum CO2 mitigation, and second, commodity animal feeds production for maximum economic benefit. A secondary objective […]
The DOE completed an illuminating workshop on Carbon Capture and Sequestration with relation to algae-based technologies, and The Digest has prepared a selection of key slides presented by AquaFiber, Pacific Northwest National Lab, University of South Florida, Algenol, Montana State University, University of Toledo, NREL, Lawrence Livermore National Lab, and RTI.
Green Biologics is focused on the production of renewable n-butanol and other C4 chemicals from various renewable feedstocks, including sugar (cane, molasses, beets), starch (corn) and cellulosic biomass (corn residues, sugar cane bagasse, forest materials and grasses). GBL works with feedstock partners to deliver capital efficient production models, and works with downstream partners to deliver […]
Global Bioenergies is a pioneer in the development of one-step fermentation processes for the direct and cost-efficient transformation of renewable resources into light olefin hydrocarbons, the key building blocks of the petrochemical industry. Since inception, the company focused its efforts on the production of isobutene, one of the most important petrochemical building blocks that can […]
At the 2017 DOE Project Peer Review, John Staser of Ohio University gave this illuminating overview on a continuous electrochemical process to convert biorefinery waste lignin to substituted aromatic compounds for resins and resin binders. The hope? To generate additional biorefinery revenue stream and reduce the cost of biofuels to be competitive with petroleum fuels.
Lysle Whitmer on behalf of an Iowa State-led group of researchers gave this illuminating overview of Liquefaction of Forest Biomass to Drop-in Fuels, at the 2017 DOE Project Peer Review sessions.
