  2. 1. Development of a Generic Model for Life Cycle Inventory and Environmental Assessment of Upstream Processes for Electronic Products

    Author : Anders Andrae; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-In-a-Package; electronic products; upstream processes; life cycle inventory; life cycle assessment;

    Abstract : The goal with the present thesis is to develop tools, methods and models to assess the upstream processes in the life cycle assessment (LCA) methodology for current and new electronic products. The goal is to get a better understanding on how to collect data to be used in a life cycle inventory (LCI) and use life cycle approaches to environmentally assess the electronics. READ MORE

  4. 2. The Karma of Products : Exploring the Causality of Environmental Pressure with Causal Loop Diagram and Environmental Footprint

    Author : Rafael Laurenti; Björn Frostell; Andrius Plepys; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Products; Environmental Pressure; Causal Loop Diagram; Environmental Footprint; Industrial Ecology; Industriell ekologi;

    Abstract : Environmental pressures from consumer products and mechanisms of predetermination were examined in this thesis using causal loop diagram (CLD) and life cycle assessment (LCA) footprinting to respectively illustrate and provide some indicators about these mechanisms. Theoretical arguments and their practical implications were subjected to qualitative and quantitative analysis, using secondary and primary data. READ MORE

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

    Author : Hampus André; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Chemicals in consumer products : Bridging the gap between academic research and chemicals regulation

    Author : Linda Molander; Christina Rudén; Magnus Breitholtz; Laura N. Vandenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; consumer products; articles; chemicals; chemicals regulation; REACH; risk management; health risk assessment; non-standard toxicity studies; study evaluation; reporting guidance; endocrine disrupting compounds; bisphenol A; low dose effects; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Exposure to chemicals emitting from consumer products, such as clothes, electronic devices, toys and kitchen-ware, has emerged as an issue of public health and environmental concern. The use of chemicals having endocrine disrupting properties in commercial products is receiving particular attention as low dose exposures of such chemicals have been associated with adverse effects in both human and wildlife populations.
