New use for paper industry's sludge and fly ash in plastics
February 27, 2017 03:11 PM - VTT Technical Research Centre of Finland
VTT Technical Research Centre of Finland examined, as part of the EU's Reffibre project, whether new industrial applications could be developed for various types of sludge and fly ash generated by the paper and board industry. Laboratory tests showed that these side streams can replace up to 50% of oil-based polypropylene. They can be used as a raw material in plastic composites made using injection moulding and extrusion.
