  1. 1. Hantering av deponier i Sverige

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Filip Lilja; [2024]
    Nyckelord :Deponier; äldre nedlagda deponier; efterbehandling; förorenade områden; MIFO; giftfri miljö; Technology and Engineering;

    Sammanfattning : Avfallshanteringen har genom tiderna bestått av mycket deponering där allt avfall som uppstod slängdes i naturen utan adekvata skyddsåtgärder, vilket idag utgör förorenade områden. Ett förorenat område kan medföra skada eller olägenheter för människors hälsa och miljö. LÄS MER

  3. 2. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

  4. 3. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ivana Pia Saric Söderholm; Erik Readwin; [2023]
    Nyckelord :Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

    Sammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

  5. 4. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Reza Doulati; [2023]
    Nyckelord :vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

    Sammanfattning : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. LÄS MER

  7. 5. The impact of green taxes on waste reduction – A case study of the impact of two Spanish taxes to support the transition to a Circular Economy

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lucía Cañas Rivera; [2023]
    Nyckelord :Circular Economy; Green Taxes; Landfill; LRSC; Plastic; SMEs; Waste;

    Sammanfattning : The current global waste problem presents significant challenges worldwide, and Spain is no different. Factors such as rapid urbanization, population growth, intensive agriculture, linear production models, and changing consumption patterns contribute to the upward trend in waste generation. LÄS MER
