By Lynn L. Bergeson On September 7, 2018, U.S. Congressman David Young (R-IA) introduced, in a bipartisan effort with U.S. Congressman Collin Peterson (D-MN), the Restoring Our Commitment to Renewable Fuels Act. Under this bill, the U.S. Environmental Protection Agency (EPA) would be required “[t]o provide for reallocation of the renewable fuel obligation of exempted small refineries under section 211(o) of the Clean Air Act (42 U.S.C. 7545(o)) to other refineries, blenders, distributors,...

By Lynn L. Bergeson On August 24, 2018, researchers from the University of Kent, UK, published a study on a new technique developed to use bacteria as cell factories to produce biofuels. Working in partnership with scientists from University College London, the University of Bristol, and Queen Mary University of London, Matthew J. Lee et al., uncovered a biotechnical approach to redesign bacterial structures called organelles. The latter, also known as bacterial microcompartments (BMC), carries...

By Lynn L. Bergeson On August 30, 2018, researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology (Fraunhofer IGB) published an article announcing the latest advances in using 3-carene as a building block to produce biobased plastics. The aforementioned substance, 3-carene, “is a component of turpentine oil, a waste stream of the production of cellulose from wood.” This substance can be found in pine, larch, or spruce and is usually a byproduct that ends...

By Lynn L. Bergeson Methylene blue consists of a blue dye used in the textile industry. A new study, published in mid-August 2018, reveals that the dye can be repurposed for use in redox flow batteries. After establishing that the chemical compound has electrochemical properties, chemists at the University of Buffalo divulged that, as an active ingredient, it can be used to store energy. In the textile industry, only about five percent of methylene blue...

By Lynn L. Bergeson On September 4, 2018, the U.S. Department of Energy (DOE) announced its support for projects in Bioenergy Research and Development. The projects total about $80 million and address early-stage research and development in the hopes of achieving DOE’s goal of reducing biobased costs in fuels by 2022. Funding for these projects comes from four different programs:  BioEnergy Engineering for Products Synthesis, Efficient Carbon Utilization in Algal Systems, Process...

By Lynn L. Bergeson At Macquarie University in Sydney, Australia, Dominik Kopp, a Ph.D. student, has developed a method for turning coffee waste into biodegradable plastic coffee cups. Because of its properties, sugars are an efficient source that is often converted into biobased chemicals. According to this study, coffee grounds consist of 50 percent sugars that can be converted into lactic acid. Once this is done, lactic acid can be used to produce biodegradable plastics....

By Lynn L. Bergeson In a research study conducted at the University of Nottingham School of Biosciences, a team of scientists has uncovered how to refine seawater to produce bioethanol. When fermented, marine yeast of the Saccharomyces cerevisiae AZ65 strain and yeast extract peptone dextrose (YPD) aid in the production of biofuels. Not only is this discovery key in the development of renewable energy sources, but it also reduces the water footprint of ethanol. Through...

By Lynn L. Bergeson On August 23, 2018, U.S. Senators Patty Murray (D-WA), Roy Blunt (R-MO), and 37 others submitted a bipartisan letter, asking the U.S. Environmental Protection Agency (EPA) to increase the renewable volume obligations under the Renewable Fuel Standard (RFS) as proposed by EPA in June 2018. Under the aforementioned proposed RFS, EPA would raise the advanced biofuel volume for 2019 to 4.88 billion gallons and the biomass-based diesel volume for 2020 to...

By Lynn L. Bergeson On August 17, 2018, researchers from the Tokyo Institute of Technology (Tokyo Tech) announced its progress in accelerating the process of biofuel-making. Through the use of biotechnology, their research demonstrates that an enzyme, glycerol-3-phosphate acyltransferase (GPAT) from the red algae Cyanidioschyzon merolae, can contribute to the biofuel production process. Algae is often used to produce biofuels because it contains high amounts of triacyglycerols (TAG) under...

By Lynn L. Bergeson Researchers from the University of British Columbia, in Canada, have discovered a new technique that can be used to transform “fatbergs” into green fuel. What scientists now refer to as “fatbergs” consist of oils and greases that cause blockages in the sewer systems accumulating disposed solids. These Canadian scientists revealed a new method in which “fatbergs” can be recycled into green fuel within the sewer system through a...
