  1. 1. Life-Cycle Considerations for Environmental Management of the Swedish Railway Infrastructure

    Författare :Niclas Svensson; Mats Eklund; Tomas Kåberger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Enviornmental management; railways; life cycle perspective; environmental pressures; material use; Miljöledning; järnvägar; livscykelperspektiv; miljöpåverkan; materialhantering; Environmental engineering; Miljöteknik;

    Sammanfattning : Syftet med den här avhandlingen är att förbättra möjligheter till miljöledning av järnvägens infrastruktur genom att utveckla en metod för att rikta in ansträngningar på att minska miljöpåverkan från infrastrukturens produkter. Metodens används i ett byggprojekt och dess robusthet blir testad. LÄS MER

  3. 2. Scoping environmental pressure from material use for strategic environmental management : case of the Swedish National Rail Authority

    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis aim is to develop an approach for scoping of environmental aspects regarding the material use in a large organisation in order to contribute to a strategic environmental management. The study object is the Swedish National Rail Authority. LÄS MER

  4. 3. Sustainability performance of multi-utility tunnels : Sustainability assessments for furthering knowledge and understanding

    Författare :Filip Bergman; Joakim Johansson; Niclas Svensson; Stefan Anderberg; Sofia Lingegård; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-utility tunnel; Cable and pipe networks; Subsurface infrastructure; Sustainability assessment; Urban underground;

    Sammanfattning : The multi-utility tunnel has received increased attention as an alternative method for the installation of subsurface infrastructure for the distribution of electricity, water, sewage and district heating. In previous research, the multi-utility tunnel (MUT) has been described as a more sustainable technology compared to the conventionally used technique where the cables and pipes are placed with open-cut excavation (OCE), especially when the entire life cycle is taken into account.

  5. 4. Utilizing CO2 from biomethane production : Sustainability and climate performance

    Författare :Stephanie S. Cordova; Mats Eklund; Marcus Gustafsson; Niclas Svensson; Valentina Bisinella; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; Carbon capture and utilization; CCU; CO₂ utilization;

    Sammanfattning : Biogas solutions offer many benefits for the environment and society, including organic waste treatment as well as being an enabler for energy and nutrient recovery. The products of anaerobic digestion are a biogas, which contains a share of 30 to 50% carbon dioxide (CO2) and 50 to 70% methane, and a liquid remanent, rich in nutrients. LÄS MER

  7. 5. Developing strategies for improved economic performance and reduced climate impact of landfill mining in Europe

    Författare :John Laurence Esguerra; Joakim Krook; Niclas Svensson; Steven Van Passel; Anders Damgaard; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; landfill management; resource recovery; sustainability assessment; emerging concept;

    Sammanfattning : Landfill mining refers to the re-circulation of resources from the previously deposited wastes. It is an alternative approach for managing landfills that integrates resource recovery with site remediation. LÄS MER
