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. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products

   Författare :Hampus André; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; scarce metals; life cycle assessment; resource-efficiency; electronic products; resource depletion; circular economy; metal resource use;

   Sammanfattning : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. LÄS MER

4. 3. Communication of life cycle assessment results : life cycle key performance indicators

   Författare :Helena Nydahl; Thomas Olofsson; Anders P. Åstrand; Staffan Andersson; Åsa Wahlström; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Monetary Valuation; Climate Impact; Life Cycle Key Performance Indicators; Global Warming Potential; LCA-result communication; Interpretation of LCA-results; climate change; klimatförändringar;

   Sammanfattning : The global warming that we are on track for will result in a severe loss of natural capital leading to significant losses in economic capital when urban infrastructure is destroyed, agricultural productivity declines and poverty spread among other disasters. Climate change due to emissions does not only affect the polluter, the hazardous effects becomes evident on a global level. LÄS MER

5. 4. 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.

7. 5. 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.
