  2. 1. Towards a Circular Economy with Environmental Product Policy : Considering dynamics in closing and slowing material loops for lighting products

    Author : Jessika Luth Richter; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extended producer responsibility; Circular Economy; critical materials; Policy Evaluation; product lifetime; lamps; lighting products; WEEE; Product Policy; ecodesign;

    Abstract : A Circular Economy (CE) can help to achieve the sustainable development goal of responsible consumption and production. Product policies, in turn, can support CE objectives by promoting reuse of products, recycling of materials, and providing ecodesign incentives for more durable products. READ MORE

  4. 2. Extended Producer Responsibility for Closing Material Loops: Lessons from energy-efficient lighting products

    Author : Jessika Luth Richter; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extended Producer Responsibility; recycling; fluorescent lighting; waste management; Policy Evaluation; LEDs; WEEE Directive;

    Abstract : The transition to a low-carbon economy requires enabling technologies including energy-efficient lighting products. It is increasingly recognized that a sustainable economy is not only low-carbon and energy efficient, but also resource efficient. READ MORE

  5. 3. Assessing Mineral Resource Scarcity in a Circular Economy Context

    Author : Hampus André; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resource-efficiency; area of protection - natural resources; electric and electronic equipment; supply risk; scarce metals; criticality assessment; material flow analysis; life cycle assessment; circular economy; complex products;

    Abstract : Due to humanity’s dependence on metal resources there are growing concerns regarding impacts related to their potential scarcity, both for current and future generations. The vision of a more circular economy suggests that extending the functional use of metals through measures aiming for resource-efficiency (RE) such as increasing technical lifetime, repairing and recycling could reduce mineral resource scarcity.

  6. 4. Hierarchical Variance Reduction Techniques for Monte Carlo Rendering

    Author : Petrik Clarberg; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer graphics; Monte Carlo methods; importance sampling; hierarchical techniques; rendering;

    Abstract : Ever since the first three-dimensional computer graphics appeared half a century ago, the goal has been to model and simulate how light interacts with materials and objects to form an image. The ultimate goal is photorealistic rendering, where the created images reach a level of accuracy that makes them indistinguishable from photographs of the real world. READ MORE

  7. 5. On computer visualization of interior wood

    Author : Enar Nordvik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Technology; Träteknik;

    Abstract : Our impressions are important for the decision of purchasing a product or not. If the product is not yet produced, communication in form of visualisations or representations is needed. Computer visualisation of interior wood products therefore requires knowledge about the feelings and attitudes the visualisation evokes. READ MORE
