  2. 1. Waste-integrated biorefineries : A path towards efficient utilization of waste

    Author : Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Pyrolysis; Anaerobic digestion; Process integration; Aspen Plus; Ebsilon; Techno-economic analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. READ MORE

  4. 2. Conversion of biomass and waste using highly preheated agents for materials and energy recovery

    Author : Pawel Donaj; Wlodzimierz Blasiak; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; waste; pyrolysis; gasification; ASR; Metallurgical process engineering; Metallurgisk processteknik; SRA - Energy; SRA - Energi;

    Abstract : One of the greatest challenges of human today is to provide the continuous and sustainable energy supply to the worldwide society. This shall be done while minimizing all the negative consequences of the operation(s) to the environment and its living habitants including human beings, taking from the whole life cycle perspective.

  5. 3. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels : Experimental and Modeling Approach

    Author : Farzad Moradian; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized-bed; combustion; gasification; waste-derived fuels; biomass; ash-related problems; deposit; fouling; slagging; bed agglomeration; thermodynamic equilibrium modeling;

    Abstract : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified.

  6. 4. Strategies for Complete Recovery of Carbon in Dual Fluidized Bed Gasifiers

    Author : Sébastien Pissot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; waste; dual fluidized bed; chemical-looping; carbon; circular economy;

    Abstract : To establish a circular economy and curtail our dependency on fossil resources, technologies are needed to extract carbon from biomass and plastic waste. Dual fluidized bed (DFB) gasification is a carbon-extracting technology that offers flexibility in terms of its inputs, outputs, design, and operational conditions. READ MORE

  7. 5. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

    Author : Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

    Abstract : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.
