  1. 26. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Regan George; [2023]
    Keywords : PHA; HTC-substrate; Polymer;

    Abstract : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.

  3. 27. Profitability of optimizing biogas production in dairy farms : an experimental case study of a Swedish dairy farm´s usage of nitrogen in digestate as a nutrient resource for crop production

    University essay from SLU/Dept. of Economics

    Author : Nils Hermansson; Albin Åkerblom; [2023]
    Keywords : biogas; optimization; profitability; economic effects; organic; conventional; agriculture; dairy farms; digestate; nitrogen; biogas; optimering; lönsamhet; ekonomiska effekter; ekologiskt; konventionellt; lantbruk; mjölkgårdar; rötrester; kväve;

    Abstract : Biogas has the potential to be a contributor to sustainable energy for electricity, fuel, and heating. Because of that, there are different alternatives for biogas plants. In this study, a farm-based biogas plant for electricity production has been of interest. READ MORE

  4. 28. Modelling organic farming systems : is livestock needed for a functioning nitrogen cycle and food production?

    University essay from SLU/Dept. of Energy and Technology

    Author : Franziska Johanna Galler; [2023]
    Keywords : organic farming; livestock; stockless farming; nitrogen cycle; nitrogen use efficiency; nitrogen recycling; nutritional value; human nutrition; food system;

    Abstract : Livestock has always been an integral part of nutrient management on organic farms. Environmental, economic and idieological trends are leading to an increasing specialization of agriculture away from mixed farms with livestock. READ MORE

  5. 29. Biocatalysis in Pickering emulsions

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Christine Vera Isabel Schmidt; [2023]
    Keywords : Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Abstract : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. READ MORE

  6. 30. Growing on the roof : But in what? Examing substrates/growing media for rooftop farming

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Mikael Brocki; [2023]
    Keywords : urban rooftop agriculture; URTA; green roof; substrate; growing medium; organic matter; compost; vegetable; crop; yield; lettuce; tomato; pore; pore-size distribution;

    Abstract : Urban Rooftop Agriculture (URTA) is a novel field within urban vegetable production, which can help create access to local food in a rapidly urbanizing world. For these systems to succeed, it is vital to implement a proper choice of substrate/growing medium (SGM). READ MORE
