1. 16. Understanding the Recycling Behaviour of Householders in Multicultural Urban Areas:Case Study Järva, Stockholm

   Författare :Sviatlana Miafodzyeva; Maria Malmström; Nils Brandt; Javier R. Viguri Fuente; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste management; household waste; recycling behaviour; motivation; multiculturalism; multicultural urban area; social survey;

   Sammanfattning : Separating household waste into fractions at source is a common method of household waste collection in most European countries. In 1994 Sweden introduced producer liability legislation for packaging, which requires householders to sort, clean and recycle different types of packaging waste. LÄS MER

3. 17. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

   Författare :Mikael Danielsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

   Sammanfattning : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. LÄS MER

4. 18. Reclaiming Territory from Below : Grassroots Environmentalism and Waste Conflicts in Campania, Italy

   Författare :Salvatore Paolo De Rosa; Institutionen för kulturgeografi och ekonomisk geografi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; grassroots movements; popular environmentalism; territory; waste management; environmental conflicts; Organized crime; southern Italy; political ecology; socioecological metabolism;

   Sammanfattning : In the course of 2000s, the region of Campania in southern Italy and its capital city Naples became global icons of waste mismanagement after the images of piles of rubbish occluding their urban areas hit the headlines. Conventional explanations, in Italy and elsewhere, pointed to administrative failure, cultural backwardness and mafia infiltration as the main causes of waste mishandling. LÄS MER

5. 19. Towards a Sustainable Resource Management : A Broader Systems Approach to Product Design and Waste Management

   Författare :Jagdeep Singh; Björn Frostell; William Hogland; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Resource Management; Product Design; Waste Management Challenges; Systems Thinking; Sustainability Science; Industrial Ecology; Industriell ekologi; Resource Management; Product Design; Waste Management Challenges; Systems Thinking; Sustainability Science;

   Sammanfattning : Rapid economic growth, urbanisation and increasing population have caused (materially intensive) resource consumption to increase, and consequently the release of large amounts of waste to the environment. Numerous technological and operational approaches to resource management have been introduced throughout the system of production, consumption and waste management. LÄS MER

7. 20. Hydrometallurgical Treatment of Neodymium Magnet Waste

   Författare :Marino Gergoric; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; recycling; rare-earth elements; leaching; Keywords: neodymium magnets; solvent extraction;

   Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.
