  1. 1. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Harry Tibbetts; [2023]
    Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

  3. 2. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Adnan Asif Rifat; [2023]
    Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

  4. 3. ARCTIC MYCORRHIZAL INTERACTIONS UNDER CLIMATE CHANGE

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Otto Minas; [2022-07-06]
    Keywords : Climate change; Arctic ecology; arbuscular mycorrhiza; graminoids; plant ecology; soil ecology; carbon cycle.;

    Abstract : The Arctic is experiencing climate change at an extreme rate, affecting both the rates of plant growth and nutrient cycling. Due to the changes in temperature, but also in nutrient cycling, with increased nutrient mineralization and decreasing P:N ratio (phosphorus, P and nitrogen, N), the arbuscular mycorrhizal fungi (AM) that are prevalent in warmer soils have shown the potential to increase in the otherwise unfavorable Arctic environment.

  5. 4. Exploring the role of business intermediaries to advance circular bioeconomy : multi case study on plant-essential nutrient recycling firms and users in Sweden

    University essay from SLU/Dept. of Economics

    Author : Urankhaich Batsukh; [2022]
    Keywords : business model; circular bioeconomy; intermediary; nitrogen; nutrient recycling; phosphorus; sewage sludge; wastewater;

    Abstract : Nitrogen (N) and phosphorus (P) are key biological nutrients for global crop production and are directly linked to global food security. Despite the enormous agricultural expansion in the past century, excessive use of these elements is causing biochemical imbalances that lead to overstepping the ‘planetary boundaries’ beyond what the earth can hold.

  6. 5. Environmental Impacts of a Wastewater Treatment Plant – With Sidestream Deammonification

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Malin Ekman; [2020]
    Keywords : Deammonification; LCA; Life cycle assessment; WWTP; Wastewater treatment; Avloppsrening; Avloppsreningsverk; Deammonifikation; LCA; Livscykelanalys;

    Abstract : Människan ger upphov till avloppsvatten varje dag. Kommunalt avloppsvatten är rikt på kol, kväve och fosfor, vilka har en stor miljöpåverkan. Vattenrening är i och med detta en nödvändighet för att minimera den antropogena inverkan på naturen och den biologiska mångfalden. READ MORE
