  1. 1. Heritability of methane emission in Swedish Red cattle in northern Sweden

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Lucy Chipondoro; [2024]
    Keywords : methane emission; heritability; swedish Red cattle; dairy cow;

    Abstract : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. READ MORE

  3. 2. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Hampus Holmberg; [2023-06-22]
    Keywords : ;

    Abstract : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. READ MORE

  4. 3. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Fanny Blom; [2022]
    Keywords : wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Abstract : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. READ MORE

  5. 4. Optimization of a two-step anaerobic treatment of wastewater from the Pulp and Paper Industry

    University essay from KTH/Industriell bioteknologi

    Author : Sara Bard; [2022]
    Keywords : Wastewater treatment; biogas; methane; pulp and paper mill wastewater; wood raw material; anaerobic treatment; sulphate reduction; UAPB reactor; Vattenrening; biogas; metan; processvatten från pappers- och massaindustrin; träråvara; anaerob rening; sulfatreduktion; UAPB reaktor;

    Abstract : Under de senaste 30 åren så har antalet massa- och pappersbruk minskat medan den totala produktionen av massa och papper har ökat. En högre produktion per bruk tillsammans med en hårdare miljölagstiftning, sätter ett högre tryck på vattenreningen på varje bruk. READ MORE

  6. 5. 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
