1. 1. Life cycle assessment in the development of forest products : Contributions to improved methods and practices

   Författare :Gustav Sandin; Magdalena Svanström; Greg Peters; Mats Westin; Annica Pilgård; Michael Narodoslawsky; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R D; LCA; Life cycle assessment; wood; forest product; forestry; impact assessment; scenario modelling; end-of-life modelling; allocation; multi-functional; planetary boundaries; life cycle inventory; life cycle impact assessment; environmental assessment;

   Sammanfattning : The prospect of reducing environmental impacts is a key driver for the research and development (R&D) of new forest products. Life cycle assessment (LCA) is often used for assessing the environmental impact of such products, e.g. for the purpose of guiding R&D. LÄS MER

3. 2. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

   Författare :Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

   Sammanfattning : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. LÄS MER

4. 3. Assessment of tools for environmentally preferable procurement with a life cycle perspective : the case of acquisition in Swedish defence

   Författare :Elisabeth Hochschorner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Acquisition; Ecodesign tools; Life Cycle Assessment; LCA; MECO; Public procurement; Simplified; Kemiteknik; Chemical engineering; Kemiteknik;

   Sammanfattning : Procurement in public and non-public organisations has the potential to influence product development towards more environmentally preferable products. In 2003, public procurement in Sweden was 28% of GDP. Different types of approaches can contribute some knowledge and thereby facilitate the choice of environmentally preferable products. LÄS MER

5. 4. Improved methods and practices in life cycle assessment of wastewater and sludge management

   Författare :Sara Heimersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; Life cycle assessment; decision basis; biosolids; sewage sludge; environmental impact;

   Sammanfattning : Large amounts of municipal and industrial wastewater are treated each year in order to prevent negative consequences to human health and the environment. The treatment processes, directly or indirectly, give rise to environmental impact, but also offer several possibilities to recover resources. LÄS MER

7. 5. Environmental, health, and safety assessment of chemical alternatives during early process design: The role of predictive modeling and streamlined techniques

   Författare :Gulnara Shavalieva; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LCA; EHS; CAMD; acute aquatic toxicity; phase-change solvents; Predictive modeling; carbon capture; knowledge extraction;

   Sammanfattning : Industrial chemicals are important for many aspects of modern life, though they can be harmful to the environment and human health. Environmental or safety concerns identified during the early design and selection of chemicals could motivate choices as to safer alternatives and process setups. LÄS MER
