  2. 6. Biomass residues as resources : An expanded life-cycle perspective

    Author : Johanna Olofsson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass residues; biofuels; life cycle assessment; climate change; circular bioeconomy;

    Abstract : Biomass residues have been identified as potentially promising resources for production of bio-based products and fuels with low climate impacts. Unlike primary biomass such as crops, using residual biomass may avoid issues such as competition over land for food and feed production. READ MORE

  4. 7. On the optimal use of industrial-generated biomass residues for polygeneration

    Author : Marianne Salomón Popa; Torsten Fransson; Andrew Martin; Lasse Rosendahl; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Optimization; Palm Oil; Biomass; forest residues; Colombia; Sweden;

    Abstract : Increasing energy demand as well as climate change concerns call for an analysis and optimization of energy services. Efficient use of energy resources, mitigation of environmental effects and supply an increasing demand are just some of the issues that are relevant nowadays in the energy system. READ MORE

  5. 8. Valorization of biomass related substrates into value added chemicals : Hydrogen transfer catalysis

    Author : Nitish Kumar Garg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomass; levulinic acid; hydrosilylation; borrowing-hydrogen; N-alkylation;

    Abstract : In the current global scenario, it is evident that global warming and climate change are primarily driven by emissions stemming from the utilization of fossil fuels. Yet, if we look around, most of what we see is made from or linked to fossil fuels and it clearly shows our over-dependency on fossil fuels and hence there is a significant need to develop alternate sources of energy and raw materials to tackle these problems.

  6. 9. Separation of Biomass Components by Membrane Filtration - Process Development for Hemicellulose Recovery

    Author : Holger Krawczyk; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; hemicelluloses; pulp mill process water; alkaline extract; membrane filtration;

    Abstract : One of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. READ MORE

  7. 10. Mild Wet Torrefaction and Characterization of Woody Biomass from Mozambique for Thermal Applications

    Author : Carlos Alberto Cuvilas; Weihong Weihong Yang; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Wet torrefaction; Fast Pyrolysis; kinetics; Catalyst;

    Abstract : Mozambique has vast forestry resources and also considerable biomass waste material such as bagasse, rice husks, sawdust, coconut husks and shells, cashew nut shell and lump charcoal waste. The potential of the total residues from the agricultural sector and the forest industry is estimated to be approximately 13 PJ. READ MORE
