  1. 6. On Food Price Implications from Expanded Bioenergy Production

    Författare :David Bryngelsson; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; food price effects; Sub-Saharan Africa; partial equilibrium model; bioenergy; staple crops; land use competition; household survey;

    Sammanfattning : Bioenergy has been put forward as a solution to energy security and at the same time to climate change. It is, however, dependent on productive agricultural land, which is a limited resource. LÄS MER

  3. 7. Perspectives on bioenergy futures - International bioenergy trade and bioenergy expansion in a European policy context

    Författare :Julia Hansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sweden; policy; CO2 credits; bioenergy trade; EU; biofuels; biofuels for transport; bioenergy; energy systems model; biomass; electricity;

    Sammanfattning : Biomass can be used to substitute the use of fossil fuels in the energy system. Presently, the use of biomass is being promoted in Sweden and the rest of the EU by targets and policies. LÄS MER

  4. 8. Towards Sustainable Bioenergy - Governance, Resource potentials and Trade-offs

    Författare :Oskar Englund; Evelyne Thiffault; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sustainability standards; trade-offs; Bioenergy; biodiversity; governance; biomass potentials; certification;

    Sammanfattning : The global energy system needs to be transformed from fossil dependent to renewable, to cope with the challenges of resource scarcity and climate change. Bioenergy can play an important role in this transformation, but land is scarce, and uncontrolled bioenergy expansion could have unacceptable consequences. LÄS MER

  5. 9. Pyrolysis of Biodegradable Waste for Negative Carbon Emissions

    Författare :Shule Wang; Weihong Yang; Pär Jönsson; Chunfei Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Organic fraction of municipal solid waste OFMSW ; Anaerobic digestion; Bioenergy with carbon capture and storage BECCS ; Methane production; 热解，市政污泥，消化物，碳负排放，生物降解垃圾，甲烷，生物能源与碳捕获和储存; pyrolys; slam; rötrester; negative kolemissioner; biologiskt nedbrytbart avfall; metan; BECCS; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Sammanfattning : Bioenergy with Carbon Capture and Storage represents a crucial technology that enables an energy production with negative carbon emissions, which is needed to achieve global climate goals. Appropriated management of biodegradable waste, including biodegradable lignocellulosic waste, sewage sludge, organic fraction of municipal solid waste, can make this contribution. LÄS MER

  7. 10. Evaluating Swedish seaweeds for biorefinery

    Författare :Joakim Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; proteins; carbohydrates; salinity; chemical composition; ulvan; variation; Ulva spp.; Seaweed; macroalgae; hydrothermal liquefaction;

    Sammanfattning : A sustainable future demands a transition from oil to biomass to produce fuels, chemicals, commodities, and energy. However, to generate the predicted amount of bioenergy required by 2050, all the biomass harvested today should be utilized. One type of biomass that has received relatively little attention is seaweeds. LÄS MER
