  2. 16. Evaluation of emerging forest-industry integrated biorefineries : Exploring strategies for robust performance in face of future uncertainties

    Author : Jonas Zetterholm; Elisabeth Wetterlund; Joakim Lundgren; Johanna Mossberg; Yawer Jafri; Damiana Chinese; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; Biomass; Forest industry; Biofuels; Investment; Gasification; Fast pyrolysis; Energiteknik; Energy Engineering;

    Abstract : Biorefineries have been promoted to reduce dependency on fossil resources, increase self-sufficiency, and revitalise rural areas. Commercial deployment of forest-based biorefineries has been slow, although academic research has identified several technology options as promising in terms of both costs and resource usage.

  4. 17. Environmental Assessment of Emerging Bio-based Production - Possibilities in a Future Bio-economy

    Author : Anna Ekman; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; Bio-based chemicals; Life cycle assessment; Industrial biotechnology; Bio-economy;

    Abstract : The bio-economy has been put forward as a strategy to increase economic growth without this leading to increased emissions of greenhouse gases. A key concept behind the bio-economy is the increased use of biomass for applications such as the production of bio-based chemicals and materials but also an increased importance for biotechnology and biorefinery systems in the production of these products.

  5. 18. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities

    Author : Katarina Åberg; Anders Nordin; Linda Pommer; Erik Dahlquist; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; biorefinery; thermochemical conversion; torrefaction; slow pyrolysis; gasification; process integration; carbon negativity;

    Abstract : The replacement of fossil resources through renewable alternatives is one way to mitigate global climate change. Biomass is the only renewable source of carbon available for replacing oil as a refining feedstock. Therefore, it needs to be utilized not just as a fuel but for both biochemical and thermochemical conversion through biorefining. READ MORE

  6. 19. From Waste to Wealth: Transforming Biorefineries into Platforms to Valorize Low-Quality Residues

    Author : Miguel Sanchis Sebastia; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; Animal Bedding; Waste Textiles; Biomass; Biotechnology; Process Design;

    Abstract : The transition to a bioeconomy, in which resources from biowaste could be reclaimed for the production of chemicals, materials or fuels, could contribute to the establishment of a sustainable society by replacing fossil fuels as raw materials. The core of this bioeconomy would be biorefineries, which are similar to petroleum-based refineries, but are facilities where biowaste is processed and refined through different chemical and/or biochemical processes.

  7. 20. Benefits of Integrated Upgrading of Biofuels in Biorefineries - Systems Analysis

    Author : Eva Ingeborg Elisabeth Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; systems analysis; biorefinery; process integration; CO2 emissions; biofuels;

    Abstract : As a result of increasing concerns about climate change, there is considerable current interest in increasing use of CO2-neutral biofuel in the energy system. Increased use of biomass fuel requires that it be upgraded in order to facilitate transportation and distribution to end-users. READ MORE
