1. 11. Exploring the relevance of uncertainty in the life cycle assessment of forest products

   Författare :Frida Røyne; Mats Tysklind; Stina Jansson; Johanna Berlin; José Potting; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCA; wood; forestry; uncertainty; biorefinery; industrial symbiosis; allocation; system boundaries; bio-economy; LCA; trä; skogsbruk; osäkerhet; bioraffinaderi; industriell symbios; allokering; systemgränser; bioekonomi;

   Sammanfattning : The role of forest biomass as a replacement for fossil fuels and products is becoming increasingly prominent as a means to mitigate climate change. To guide a sustainable transition towards a forest-based bio-economy, it is important that advantages and disadvantages of forest products are assessed, to ensure that the products deliver environmental impact reduction.

3. 12. Towards Sustainable Use of Chemicals in the Textile Industry: How life cycle assessment can contribute

   Författare :Sandra Roos; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Toxicity; Textile; LCA; Chemicals; Impact assessment;

   Sammanfattning : The use of chemicals in the textile industry is a topic that has been given increasing attention in recent years. Hazardous chemicals are found in textile consumer products on a regular basis, and there is an increased awareness of the health and environmental impact caused by emissions of hazardous chemicals in the countries where textile production occurs.

4. 13. Life Cycle Assessment of Building Products. Case Studies and Methodology

   Författare :Åsa Jönsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOCs; environmental assessment; floorings; methods; LCA; concrete; indoor climate; Life Cycle Assessment; structural frames; building materials; steel; tools;

   Sammanfattning : The main objectives of this thesis were to demonstrate how Life Cycle Assessment (LCA) may be applied to building products, to describe what methodological LCA issues are specific to building products, to work out solutions to some of these issues and to relate LCA to other environmental assessment methods that may be applied to building products. First, in a literature study, the state of the art in the field of environmental assessment of building products is described, and the five articles constituting the thesis are put into context.
