  • Global Production of Second Generation Biofuels: Trends and Influences
    GLOBAL PRODUCTION OF SECOND GENERATION BIOFUELS: TRENDS AND INFLUENCES January 2017 Que Nguyen and Jim Bowyer, Ph. D Jeff Howe, Ph. D Steve Bratkovich, Ph. D Harry Groot Ed Pepke, Ph. D. Kathryn Fernholz DOVETAIL PARTNERS, INC. Global Production of Second Generation Biofuels: Trends and Influences Executive Summary For more than a century, fossil fuels have been the primary source of a wide array of products including fuels, lubricants, chemicals, waxes, pharmaceuticals and asphalt. In recent decades, questions about the impacts of fossil fuel reliance have led to research into alternative feedstocks for the sustainable production of those products, and liquid fuels in particular. A key objective has been to use feedstocks from renewable sources to produce biofuels that can be blended with petroleum-based fuels, combusted in existing internal combustion or flexible fuel engines, and distributed through existing infrastructure. Given that electricity can power short-distance vehicle travel, particular attention has been directed toward bio-derived jet fuel and fuels used in long distance transport. This report summarizes the growth of second-generation biofuel facilities since Dovetail’s 2009 report1 and some of the policies that drive that growth. It also briefly discusses biofuel mandates and second-generation biorefinery development in various world regions. Second generation biorefineries are operating in all regions of the world (Figure 1), bringing far more favorable energy balances to biofuels production than have been previously realized. Substantial displacement of a significant portion of fossil-based liquid fuels has been demonstrated to be a realistic possibility. However, in the face of low petroleum prices, continuing policy support and investment in research and development will be needed to allow biofuels to reach their full potential.

However, large-scale biorefineries are not yet cost-competitive with their fossil-fuel counterparts, and it is important to identify biorefinery concepts with high economic performance. For evaluating early-stage biorefinery concepts, one needs to consider not only the technical performance and process costs but also the economic performance of the full supply chain and the impacts on feedstock and product markets. This article presents and demonstrates a conceptual interdisciplinary framework that can constitute the basis for evaluations of the full supply-chain performance of biorefinery concepts. This framework considers the competition for biomass across sectors, assumes exogenous end-use product demand, and incorporates various geographical and technical constraints.

  • Lantmännen Agroetanol, Sweden Bioenergy
    Lantmännen Agroetanol, Sweden Bioenergy Stringent CO reduction criteria lead to business Success Stories 2 success IEA Bioenergy: 02 2018 Year of implementation: 2005, updated 2015 Location: Norrköping, Sweden Technology: Ethanol biorefinery Location of the ethanol plant close to biomass-based CHP ensures deliveries of renewable electricity and process heat. Principle feedstocks: Wheat and other grains, as well as starch-rich residues from the food industry Products/markets: Fuel ethanol and co-products in the form of protein-rich feed. A further co-product here is the (biobased) carbon dioxide that is captured and sold as industrial raw material to customers in the food processing and packaging industry. Technology Readiness TRL 9 – actual system proven in operational environment Level (TRL): DESCRIPTION Lantmännen is a Swedish agricultural cooperative owned by 25,000 Swedish farmers, providing food, feed and fuel nationally and internationally. Since 2001, Lantmännen has produced fuel ethanol at a facility in Norrköping in South-Eastern Sweden based on wheat and other grains as well as residues from the food industry. The plant was initiated to develop new markets for agricultural products. Thanks to efficient processes, the use of renewable process energy from adjacent biomass-fueled CHP and important co-products in the form of protein-rich feed and biogas, the fuel ethanol produced reduces GHG emissions by more than 90 % compared to fossil fuels. From 2015, Lantmännen is also marketing a renewable ethanol fuel for diesel engines called Agro Cleanpower 95, which reduces GHG emissions by up to 90% compared to fossil diesel. A noteworthy co-product here is the (biobased) CO2 sold as industrial raw material to customers in the food processing and packaging industry, i.e.

Task 39 Business Virtual Meeting in June 2020 The second Task 39 business meeting of 2020 was held on June 23, virtually using Zoom. The meeting’s main purpose was to review and discuss active projects; to provide a forum for Task 39 members to share questions, thoughts and ideas regarding the scope, objectives and methodology of each project as well as its budget allocation. Project leaders presented progress updates and described next steps to seed these discussions; a listing of Task 39’s projects for the 2019-2021 triennium is provided in the previous issue of this newsletter (link). The group was excited to have India’s newly appointed country representative, Mr. Ravi P. Gupta, General Manager of Bioenergy Research Centre at the Indian Oil Corporation joining the meeting despite the difficult time zone challenges. Despite the COVID-19 pandemic disrupting global supply chains and economies, the long-distance transport sector continues to play a vital role in maintaining the delivery of essential goods and services (e.g., medical supplies, food, energy, etc.).

Accepted: May 23th, 2018 Abstract Microalgae transform CO2 into a broad portfolio of biomolecules, and thus should be considered as a valuable biotechnological platform. Despite several research programs and global efforts to establish a sustainable microalgae-based industry, most applications have not transcended academic boundaries. This limitation raises from the high transformation costs when target products are biofuels or fertilizers. Microalgae biorefinery emerges as an alternative to improve economic competitiveness, as Under such a model scope, the process inputs come from industrial waste, while biomass exploitation prioritizes the highest value molecules followed by extraction of less valuable compounds. This review describes a wide range of microalgae exploitation schemes focused on new uses of its constituents, while discussing emerging technologies designed to improve production and efficiencies as well. Keywords: microalgae; biorefinery; biofuels; fertilizers; active biomolecules.

Carlos Gomes, 1217, CEP 14801-320, Araraquara, São Paulo, Brazil 3 Suzano Papel e Celulose SA, Av. Lirio Correa, 1465, 06460-040, Limeira, São Paulo, Brazil Received November 02, 2017; Accepted January 31, 2018 ABSTRACT: Research involving the preparation of microfibrillated cellulose (MFC) from sugarcane bagasse is a relevant topic to the production of new nanomaterials and more accessible cellulose substrates for the production of second generation ethanol. Regarding the transformation of cellulose into glucose, the precursor of second generation ethanol, this nanosized cellulosic substrate represents a more appropriate material for the chemical hydrolysis process. The high aspect ratio of MFC improves hydrolysis, requiring mild conditions and decreasing the generation of by-products. Here, MFC was prepared from sugarcane bagasse by ultrasound defibrillation. This material was oxidized with 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) to produce negatively charged high defibrillated MFC. The MFC was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and viscosity measurements.
