   Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER

5. 19. Towards Large-Area Electronic Systems Using Non-Conventional Substrate and Conductor Materials

   Författare :Xiaotian Li; Johan Sidén; Henrik Andersson; Leena Ukkonen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-conventional materials; large-area electronics;

   Sammanfattning : Flexible circuits, also known as flexible printed circuit boards, were originally developed in the 1950s for interconnection between multiple electronic devices when flexibility and movement were required. Nowadays, flexible circuits can be used for implementing electronic systems much more complicated than just interconnections. LÄS MER

7. 20. Environmental assessment of construction with recycled materials

   Författare :Sofia Lidelöw; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

   Sammanfattning : The use of industrial residues as raw materials in construction raises concerns over the potential leaching and dispersal of hazardous constituents from them into the environment. Their leaching behaviour has been studied in laboratory assays, but leaching processes in the field over larger spatial and temporal scales are more complex due to variations in the conditions the materials are exposed to, and less well understood.
