  1. 26. STARTING FROM THE BOTTOM: USING LOW TROPHIC SPECIES IN SALMON FEEDS. Assessing the environmental performance of novel salmon feeds with LCA .

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Moritz Hempel; [2022-08-30]
    Keywords : LCA; Salmon aquaculture; novel feeds; seaweed; blue mussel;

    Abstract : Over the past 30 years, the formulation of salmon feeds has shifted from being based on marine ingredients like fishmeal and fish oil towards more plant-based ingredients. This shift was caused by limited supply of wild fish and general sustainability concerns related to using forage fish for feed, so they were mainly replaced with vegetable-protein. READ MORE

  3. 27. Life Cycle Assessment of Borehole Thermal Energy Storage

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Saga Karlsson; [2022]
    Keywords : ;

    Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

  4. 28. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Mehrzad Ghassemi; [2022]
    Keywords : Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Abstract : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  5. 29. A Comprehensive Review of the Factors Influencing the Environmental Impact of different Species bred in Closed Land-based Recirculating Aquaculture Systems

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Siri Samuelsson; [2022]
    Keywords : Recirculating aquaculture system; renewable electricity; Feed Conversion Ratio; environmental impact; freshwater eutrophication; climate change; land use; cumulative energy use; acidification; Earth and Environmental Sciences;

    Abstract : Today the future supply of seafood is threatened due to human activities which, among other things, has led to overfishing. However, more environmental friendly initiatives of producing seafood have emerged, such as Recirculating Aquaculture Systems (RASs). READ MORE

  6. 30. Assessment of future climate and land use changes on streamflow and phosphorus transport in a Swedish agricultural catchment

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Clara Laguna Marin; [2022]
    Keywords : surface water modelling; phosphorus; suspended sediment; climate change scenarios; socio-economic scenarios; INCA-PEco;

    Abstract : Despite efforts to reduce nutrient excess in surface waters in the last decades, eutrophication continues to be an important environmental problem in Europe. The presence of excess phosphorus (P) in waters, together with nitrogen (N), is one of its main causes. READ MORE
