  1. 1. Extended Producer Responsibility as a Driver for Design Change - Utopia or Reality?

    Författare :Naoko Tojo; Internationella miljöinstitutet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extended producer responsibility; EEE; policy evaluation; intervention theory; effectiveness; implementation; individual responsibility; complex products; cars; anticipation of mandatory instruments; batteries; design change; Commercial and industrial economics; Industriell ekonomi;

    Sammanfattning : Policies based upon Extended Producer Responsibility (EPR) aim to reduce the environmental impacts of products across their entire life cycle. The intent is to induce design changes in products and thus reduce impacts at source. This, by provision of incentives to producers through an extension of responsibility. LÄS MER

  3. 2. Recycling and processing of end-of-life electric and electronic equipment : fundamentals and applications

    Författare :Shunli Zhang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : This thesis presents a concept of scrapology of end-of-life electric and electronic equipment (EOL EEE) as a basis on which to develop effective recycling techniques. Various study approaches associated with this concept are detailed in this thesis. LÄS MER

  4. 3. Initiating Original Equipment Manufacturer Remanufacturing

    Författare :Johan Vogt Duberg; Erik Sundin; Jelena Kurilova-Palisaitiene; Ou Tang; Patricia van Loon; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remanufacturing; Circular economy; Value-retention process; Economic assessment; Initiation; Prerequisite.; Återtillverkning; Cirkulär ekonomi; Värdebevarande process; Ekonomisk värdering; Initiering; Förutsättning.;

    Sammanfattning : Remanufacturing is an industrial process in which a core – a used, discarded, or broken product – is transformed into a product whose specification and condition are new-like. However, to this date, remanufacturing activities on the market are few in comparison to manufacturing. LÄS MER

  5. 4. Genetic and Molecular Mechanisms Controlling Reactive Oxygen Species and Hormonal Signalling of Cell Death in Response to Environmental Stresses in Arabidopsis thaliana

    Författare :Per Mühlenbock; Stanislaw Karpinski; Barbara Karpinska; Pierre Frendo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi;

    Sammanfattning : In the present work the regulation of environmentally induced cell death and signaling of systemic acquired acclimation (SAA) in Arabidopsis thaliana is characterized. We used the lesion simulating disease1 (lsd1) mutant as a model system that is deregulated in light acclimation and programmed cell death (PCD). LÄS MER

  7. 5. Roles of LESIONS SIMULATING DISEASE1 and Salicylic Acid in Acclimation of Plants to Environmental Cues : Redox Homeostasis and physiological processes underlying plants responses to biotic and abiotic challenges

    Författare :Alfonso Mateo; Stanislaw Karpinski; Philip M. Mullineaux; John F. Allen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LSD1; Photooxidative stress; Reactive oxygen species; Light acclimation; Photorespiration; Salicylic acid; Plant physiology; Växtfysiologi;

    Sammanfattning : In the natural environment plants are confronted to a multitude of biotic and abiotic stress factors that must be perceived, transduced, integrated and signaled in order to achieve a successful acclimation that will secure survival and reproduction. Plants have to deal with excess excitation energy (EEE) when the amount of absorbed light energy is exceeding that needed for photosynthetic CO2 assimilation. LÄS MER
