  1. 21. The effect of high-ratio biochar replacement in concrete on performance properties : Experimental study of biochar addition to concrete mixture.

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Mina Turovaara; [2022]
    Keywords : Biochar; Concrete; Sustainability; Cement; Biochar in concrete; Carbon dioxide; Building industry; Micro-structure; Biokol; Betong; Hållbarhet; Cement; Biokol i betong; Koldioxid; Byggsektorn; Mikrostruktur;

    Abstract : Globally the emissions of carbon dioxide from anthropogenic activities are an issue regarding the future of our planet. Today the building industry is a large contributor with approximately 10 percent of the total emissions coming from energy usage in the building industry, where about 7 percent of the global CO2 emissions are connected to the cement industry.

  3. 22. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Landmér Alice; [2022]
    Keywords : Carbon fiber; cellulose; cold NaOH aq ; lignin; precursor; sodium hydroxide; solution spinning; wet spinning;

    Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE

  4. 23. Biochar Production from Municipal Sewage Sludge via Pyrolysis - The Case of Gotland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lara-Patricia Brokmeier; [2022]
    Keywords : Biochar; Municipal Sewage Sludge; Pyrolysis; Carbon Sequestration; Heavy Metals; Gotland;

    Abstract : In order to keep global average temperature below 2°C it is necessary to accelerate climate change mitigation actions and reduce global greenhouse gas emissions. This can be achieved by carbon capture and storage methods such as the production of biochar. READ MORE

  5. 24. The Optimal Bidding Strategy of a Wind-Biogas-Hydrogen Hybrid System

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Xudong Liu; [2022]
    Keywords : bidding strategy; wind; biogas; hydrogen; hybrid system; two-price settlement;

    Abstract : The growing penetration of variable renewable energy has brought all-round challenges to the current power system, no matter for the grid infrastructure, market design or the power producers. The positive and negative externalities caused by the market participators are to be finer priced and a significant amount of flexibility is to be added to the system, in order to counter these problems and facilitate energy transition.

  6. 25. Biokol som tillsats i vallensilage utfodrat till mjölkraskvigor : inverkan på konsumtionsförmåga, smältbarhet, träckens konsistens och färg, samt djurens renhet

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Ida Milton; [2022]
    Keywords : Biokol; Smältbarhet; Vallensilage; Aktivt kol; Mjölkraskvigor; Konsumtionsförmåga; Träckkonsistens; Färg; Renhet;

    Abstract : Biokol är en produkt som tillverkas av organiskt material eller biomassa i en process som kallas pyrolys, då materialet upphettas i en temperatur från 350 till 1000 ̊C i en syrefri miljö. Biokol är lagringsstabil under lång tid innan den bryts ned och fungerar därför som kolsänka. READ MORE
