Recovery and utilisation of non-metallic fraction from waste printed circuit boards in polypropylene composites

Extreme complexity in the range of polymer composition in waste printed circuit boards (WPCBs) will leave us to follow a series of steps to formulate an efficient recycling system. The current study deals with the recovery and utilisation of non-metallic fractions from WPCBs through dismantling, size reduction and sieve analysis. Density based techniques have been adopted in the current studies to separate the non-metallic fractions from metallic one due to its simplicity and cost effectiveness. The non-metallic fractions are quantified through sieve analysis and are utilised as reinforcing filler material in polypropylene matrix. Composite material with WPCBs has been prepared via melt blending techniques and is subjected to mechanical, thermal and morphological analysis to investigate its feasibility for automobile application.
