  2. 11. Biosynthesis, interactions, and structure of native lignin

    Author : Ioanna Sapouna; Lauren S. McKee; Francisco Vilaplana; Claudia Crestini; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lignin; biomass valorization; extraction; tissue culture; lignin nanoparticles; wood aerogels; lignin; biomassavalorisering; extraktion; vävnadsodling; lignin nanopartiklar; trä aerogeler; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. READ MORE

  4. 12. High temperature corrosion in a biomass-fired power boiler : Reducing furnace wall corrosion in a waste wood-fired power plant with advanced steam data

    Author : Yousef Alipour; Pamela Henderson; Peter Szalalos; Christofer Leygraf; Jan Froitzheim; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High temperature corrosion; Waterwalls; Power plant corrosion; NOx reducing enviroments; Biomass; Waste wood; Thermodynamic calculation modelling; corrosion-resistance alloy; Furnace wall corrosion; Högtemperaturekorrosion; Eldstadsväggar; kraftverks korrosion; låg Nox mijöer; biomassa; returträ; Termodynamisk modellering; korrosionsbeständighet legering; eldstadskorrosion;

    Abstract : The use of waste (or recycled) wood as a fuel in heat and power stations is becoming more widespread in Sweden (and Europe), because it is CO2 neutral with a lower cost than forest fuel. However, it is a heterogeneous fuel with a high amount of chlorine, alkali and heavy metals which causes more corrosion than fossil fuels or forest fuel. READ MORE

  5. 13. Investigating the Reaction Kinetics of Tropical Wood Biomass : A Prospect for Energy Recovery

    Author : Kehinde Oluoti; Högskolan i Borås; []
    Keywords : Wood; Pyrolysis; gasification; char; kinetic parameters; SEM-EDX; AAEM; Resursåtervinning; Resource Recovery;

    Abstract : The utilization of wood biomass for energy recovery purposes is a phenomenon that is increasingly attracting attentions from researchers, companies and countries all over the world. The effect of climate change as largely represented by global warming leading to glacier ice melting and an unprecedented rise in sea level is a worrisome development. READ MORE

  6. 14. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Author : Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Abstract : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. READ MORE

  7. 15. Carbon materials: towards a circular economy through thermochemical recycling of mixed waste

    Author : Isabel Cañete Vela; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plastic waste; circular economy; thermochemical recycling; mixed waste; recycling; Carbon materials; steam cracking;

    Abstract : Carbon-containing materials, such as paper, wood, plastic, and textiles, are essential for our daily lives, being used in everything from clothing to infrastructure. However, their use typically follows a linear pattern, in that we extract carbon resources, create products, and eventually dispose of them, thereby contributing to greenhouse gas (GHG) emissions throughout the supply chain.
