  1. 21. Towards a pre-verified EPD tool with simulation capabilities for the aggregates industry

    Författare :Panagiota Papadopoulou; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EPD; pre-verified EPD tool; aggregates; process simulations; crushing plants; Plantsmith; LCA;

    Sammanfattning : Aggregates are an indispensable component in the development of societies as they are the basic materials for most buildings and infrastructure projects. Therefore, understanding and taking actions regarding their environmental impact is necessary for the industry’s sustainable development and climate neutrality. LÄS MER

  3. 22. Capturing the life cycle environmental performance of a company’s manufacturing system

    Författare :Birger Löfgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; actor; DES; LCA; Manufacturing decision making;

    Sammanfattning : This research has developed methods for manufacturing decision makers to measure manufacturing environmental performance and to predict the environmental consequences of alternative manufacturing system configurations. The ideas behind the methods are based on life-cycle thinking from the perspective of an industrial actor, and its decision makers, in the value chain of a product. LÄS MER

  4. 23. Improved life cycle assessment of wastewater and sludge management with resource recovery

    Författare :Sara Heimersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; allocation; LCA; sludge treatment; resource utilisation; sludge handling; biosolids; pathogen risks; wastewater treatment;

    Sammanfattning : Around the world every day, large amounts of wastewater are treated before release, to avoid impacts on humans and the environment. The treatment requires resources in the form of energy and chemicals, and it generates large amounts of sewage sludge, however, it can also serve as a source of energy, nutrients and carbon. LÄS MER

  5. 24. A Life Cycle Approach to Environmental Sustainability in Aggregate Production Systems

    Författare :Christina Lee; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Aggregates; Gravel; Sand; LCA; Production Systems; Sustainability; Life Cycle Assessment; Environmental Management; EPDs; Quarries; Tool Development; Environmental Impact; Environmental Product Declarations; Construction Products;

    Sammanfattning : Rock materials, such as sand, gravel, and crushed rock, serve as the foundation of our society. Known collectively as aggregates, these materials are essential for building foundations, concrete, and roads, making them the second most extracted material globally after water. LÄS MER

  7. 25. Indicators for Measuring the Sustainability of Urban Water Systems - A Life Cycle Approach

    Författare :Margareta Lundin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indicators; wastewater systems; LCA; decision-making; environmental systems analysis; sewage sludge; sustainable development; life cycle assessment; urban water systems;

    Sammanfattning : Infrastructure for the provision of drinking water and the treatment of wastewater and stormwater, is essential for an urban society. In this project methods are developed which measure and assess the sustainability of urban water systems. LÄS MER
