  1. 1. Predicting Treatment Performance Using Ternary Plot : Macronutrients’ impact on biomass conversion efficiency

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Madeleine Gobl; [2022]
    Keywords : Black soldier fly; organic waste treatment; biomass conversion efficiency; treatment performance; macronutrients; ternary plot; organic waste; amerikansk vapensflugan; triangulär diagram; organiskt avfallsbehandling; organiskt avfall; behandlingseffektivitet; biomassomvandlings-effektivitet; makronäringsämnen;

    Abstract : Black soldier fly larvae (BSFL) waste treatment is becoming a more sought-after organic waste treatment since it produces larvae for animal feed as well as fertilizer, the need for prediction and optimization of treatment performance increases. This study aims to predict biomass conversion efficiency (BCE) for waste going into treatment, using only the nutritional data from other studies as it could give a good performance estimation while using available data.

  2. 2. Supply chain effects of utilizing non destructive quality inspection in food production

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Fredrik Klein; [2022]
    Keywords : waste; inventory; production; food; quality;

    Abstract : Reducing waste and increasing efficiency in food supply chains is important for a sustainable food production. Modified Atmosphered Packaging (MAP) is a method of increasing food durability that requires gas quality and potential gas leakage inspection. READ MORE

  3. 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

  4. 4. Rare Earth Triflate/Alanine Catalysed Diels-Alder and Michael Reactions in Water and an Alternative Pyrrole Synthesis

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Albin Olsson; [2022]
    Keywords : Water; Green Chemistry; Synthesis; Organic Chemistry; Chemistry;

    Abstract : Large amounts of organic solvents are used within the field of chemistry and nearly everything is being discarded and is not reused. A way to reduce the environmental impact that this leads to is to use a safe and natural solvent that is easy to access, like water. READ MORE

  5. 5. Carbon Flows in Sweden : A Substance Flow Analysis of anthropogenic carbon flows

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sofia Gunnarsson; [2022]
    Keywords : Carbon; Carbon Flow; Carbon Stock; Substance Flow Analysis; Sweden; Industrial Ecology; Anthropogenic;

    Abstract : Carbon (C) is an essential element for all life. However, modern livestock keeping and usage of carbon through burning of fossil fuels are resulting in increased concentrations of carbon dioxide and methane in the atmosphere, two important greenhouse gases (GHG). READ MORE
