Emerging Issue in a Proper Recycling Technology for Printed Circuit Board Waste: A Pyrolysis Based Recycling Approach

Abstract

At the present, treatment processes for non metallic fraction (NMF) from Printed Circuit Board (PCB) waste after mechanical recovery process of the precious metallic material are combustion, landfill or reuse as filler material. These cause secondary pollution and loss of natural resources. The most important aspect is the fact that (NMF) can be recovered as well. (NMF) is a matrix combination of three basic materials which are glass reinforced fiber (GRF), ceramics and thermosetting plastic. Thermosetting plastics are not able to be reheated and that causes the limitation of the ability to recycle material. Pyrolysis method has been recognized an effective resource recovery alternative by the capability to convert organic compound element into flammable liquid and gas theoretically. Hence, it is a challenge to expose a further separation between materials and recovering them. From the environmental viewpoint, The only solution to reduce the PCB waste problem sustainably is to address with a proper material recycling technology. The purpose of this study is to determine the suitability of using the pyrolysis method to process with (PCB) waste and to compare with the conventional treatment process. Pyrolysis processes and experiments has been reviewed and investigated to determine niches in the area. The result has shown that (NMF) have the potential to be utilized as pyrolytic oil. This result demonstrated the potential option in term of an alternative proper recycling process by using pyrolysis method for the non-metallic portion from (PCB) which this method could be applied effectively in economic scale.
