    Keywords : Vertical Farming”; “Life Cycle Assessment; Sweden; Environmental impacts; industrial symbiosis; Urban farming; Vertical Farming; Livscykelanalys; Sverige; Miljöpåverkan; Industriell symbios; Stadsodling;

    Abstract : The world is facing many challenges to be able to ensure food security, such as anincreased food demand coming from an expanding world population andurbanisation, worsened agricultural opportunities from increased land deteriorationand significant environmental impacts coming from the food sector. Thus, there is aneed for new agricultural solutions to meet our needs whilst decreasing impactssimultaneously. READ MORE

  3. 2. Modeling and simulation of chromatographic separation in Modelon Impact

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Oliver Thelander; [2022]
    Keywords : Chemical engineering; Simulering; Modellering; Kromatografi; Adsorption; Modelica; Modelon Impact; Recirkulation; Simulation; Modeling; Chromatography; Recirculation; Technology and Engineering;

    Abstract : The aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. READ MORE

  5. 4. The possibilities of recycling wash water at Vidinge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Julia Mauritzson; [2020]
    Keywords : reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. READ MORE

  6. 5. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ross Roberts; [2020]
    Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

    Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE
