  • What Is Metal Waste How Does The Recycling Of Metals

    The consumption of metals and the resulting metal waste is a huge environmental problem. Metal waste imposes several adverse effects on our planet. Therefore it is crucial to develop processes in order to mitigate the problem. One effective measure against the problem of metal waste is metal recycling.

  • Recycling of PVCProspects and Challenges EcoMENA

     · A major problem in the recycling of PVC is the high chlorine content in raw PVC (around 56 percent of the polymer s weight) and the high levels of hazardous additives added to the polymer to achieve the desired material quality. As a result PVC requires separation from other plastics before mechanical recycling.
