  1. 1. 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

  3. 2. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments

    Författare :Daniel Böckin; 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; Circular Business Models; guidelines; business models; synthesis; Life Cycle Assessment; decoupling; resource efficiency; 3D-printing; Circular Economy; waste hierarchy;

    Sammanfattning : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.

  4. 3. Managing high environmental performance? : Applying life cycle approaches and environmental certification tools in the building and real estate sectors

    Författare :Nils W. O. Brown; Tove Malmqvist; Peter Guthrie; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Buildings; operational energy use; life cycle assessment; environmental certification; environmental assessment; renovation; strategy; design process; value creation; embodied environmental impacts; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : The main aim of this thesis is  to demonstrate and critically assess life cycle approaches’ and environmental certification (EC) tools’ potential for supporting decisions for improved environmental performance in the building and real estate sectors.Using life cycle approaches, the thesis shows that for new build and renovation cases aiming for low operational energy use that embodied global warming potential (GWP) due to material production can constitute a large portion of a building’s lifetime GWP.

  5. 4. Enhancing Environmental Performance by Green Procurement : A study of environmental procurement preferences in the construction industry

    Författare :Annika Varnäs; Berit Balfors; Charlotta Faith-Ell; Olof Hjelm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green procurement; Environmental management; Construction industry; Environmental criteria; Environmental requirement; EIA; EMS; Public procurement; Construction project; Environmental engineering; Miljöteknik;

    Sammanfattning : In recent years, the general awareness of the environmental impacts that industrial production gives rise to has radically increased throughout the world. Finding ways to minimise these impacts has become a major concern of the authorities in many countries. LÄS MER

  7. 5. Industrial Symbiosis in the Biofuel Industry : Quantification of the Environmental Performance and Identification of Synergies

    Författare :Michael Martin; Mats Eklund; Laura Sokka; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial symbiosis; life cycle assessment; by-product; integration; environmental performance;

    Sammanfattning : The production of biofuels has increased in recent years, to reduce the dependence on fossil fuels and mitigate climate change. However, current production practices are heavily criticized on their environmental sustainability. LÄS MER
