5. 14. Sampling from large flotation cells : An invastigation of spatial distribution

   Författare :Lisa Malm; Jan Rosenkranz; Tommy Karlkvist; Anders Sand; Nils-Johan Bolin; Pertti Lamberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flotation; sampling; Mineral Processing; Mineralteknik;

   Sammanfattning : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. LÄS MER

7. 15. Fruit wastes to biomaterials : Development of biofilms and 3D objects in a circular economy system

   Författare :Veronika Bátori; Kristiina Oksman; Högskolan i Borås; []
   Nyckelord :apple pomace; biodegradable; bioplastics; circular economy; orange waste; resource recovery; Resource Recovery; Resursåtervinning;

   Sammanfattning : To address the current plastic pollution problem, the replacement of conventional plastics with bioplastics can be considered. Although the land use of crop cultivation for bioplastics is still negligible, there is an increasing interest in the utilisation of lignocellulosic waste products for the production of bioplastics.
