NOVEL CONCEPT TO TREAT WEEE FOR ENERGY AND METALS RECYCLE BASING ON PYROLYSIS PROCESS

Abstract: For the time different challenges are facing the world to stop the environment impacts  and availability of vital resources. Electrical and electronical Equipment (EEE) are contained harmful compounds which considered to be a major threat for living organisms and might cause long term impacts on environment (Md. Abdur Rakib, 2014). Furthermore, evolution of technology leads to production of a huge amount of electronic waste globally, which need to be treated by innovative technologies in order to minimize their environmental impact and simultaneously maximize their recovery rates. Pyrolysis is a promising method for treating these fractions of waste because it can potentially convert these waste into energy and metals.  Waste of Electrical and electronical Equipment (WEEE) contains both valuable and harmful materials, industrial waste are various physically and chemically from household waste. To avoid the opposite influence on environment and human health, presuppose particular recycling and treatment technique depending on the waste type (Gkaidatzis, Aggelakoglou, & Aktsoglou, 2009). Two types of WEEE have been processed using typical pyrolysis (Nitrogen) and pyrolysis (steam) at 600 °C, Fixed bed reactor was used in addition to a separate boiler for producing steam. Two samples were investigated Printed circuit board- main body and -sockets. The main focus of this work was to investigate the influence of steam presence on pyrolysis for recovering energy and metals from recycling WEEE. The comparison between pyrolysis at inert atmosphere and steam pyrolysis results of two various fractions of E-Waste were prepared, in addition to literature investigation related to recycling of E- waste and traditional routes which are followed in recovering materials nowadays was done. The results of this study  provides the incentive to continue experiments around pyrolysis process by using other methods.
