Characterization of products from pyrolysis of waste printed circuit boards

The subject of this thesis is one of the popular waste type in recent years, waste printed circuit boards (PCB) which are contained in electronic wastes. Improper disposal of waste PCBs may cause serious environmental pollution due to their glass fiber, flame retardant synthetic additives, heavy metals such as lead and mercury and bromine (Br-) content. In this thesis, it was aimed to produce valuable products from waste PCB by pyrolysis which is one of the recycling method for PCB, while capturing the bromine in the solid products. For this aim, waste PCBs were pyrolyzed with waste clay (from boron derivatives products), construction and demolition waste (C&DW) and zeolite. Pyrolysis experiments were carried out at 500°C and 30°C/min heating rate in a fixed bed reactor. According to pyrolysis results, the highest yield of liquid product is obtained on the PCB (%19,17) and the maximum capturing ratios of Br- in solid products were provided as to be PD5 (%65,88) and PZ5 (%56,10).
