  1. 21. 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

  3. 22. Comparative techno-economic analysis of BECCS and biochar in Sweden

    University essay from SLU/Dept. of Energy and Technology

    Author : Simon Martelius; [2022]
    Keywords : NETs; feasibility; cost-effectiveness; climate change-mitigation; CHP; carbon neutrality; bioenergy;

    Abstract : Greenhouse gas emissions from human activity need to decrease for the Paris agreement goal of 1.5° C of global warming to be reached, and while emission reduction efforts remain the most important tool for combating climate change, it is increasingly evident that negative emission technologies (NETs) will play a key role reaching the climate targets of the Paris agreement.

  4. 23. Climate change mitigation from biochar production at farm level : A time dynamic LCA study of wheat

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Louise Jungefeldt; [2022]
    Keywords : Pyrolysis; agricultural by-products; life cycle assessment; waste valorization; carbon sequestration;

    Abstract : Agricultural production in Sweden account for a large contribution of the territorial GHG emissions. System optimization, fossil fuel removal and increased circularity is therefore of great importance in order to reach the national net zero emission target by 2045. READ MORE

  5. 24. Biochar and Hemp as Peat Substituents in Horticultural Substrates and Their Effects on Presence of Microbiota

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Louise Hagbard; [2022]
    Keywords : biochar; hemp; Cannabis sativa; peat reduction; peat; microbiome; fibers; substrate; growing media; Trichoderma; Pseudomonas; Lactuca sativa;

    Abstract : The extraction of peat has been shown to have a detrimental impact on the environment in several ways, including through emissions of greenhouse gases but also through a negative impact on fragile habitats, ecosystems, and ecosystem services. The horticultural sector is a major user of peat products and thus contributes to both emissions and habitat changes. READ MORE

  6. 25. Low-carbon hydrogen production from waste plastics via pyrolysis and in-line catalytic cracking process

    University essay from KTH/Kraft- och värmeteknologi

    Author : Yanghao Jin; [2022]
    Keywords : Pyrolysis; catalytic cracking; plastics recycling; biochar catalyst; hydrogen production; Pyrolys; katalytisk krackning; återvinning av plast; biokol; produktion av väte;

    Abstract : This study develops a novel pyrolysis process combined with in-line catalytic reforming toproduce high purity hydrogen and carbon products from waste plastics. The input resource is waste plastic material in the form of discarded Covid masks. READ MORE
