Abstract: Present work demonstrates the PCB waste characterization using solid state route. Microwave and resistive heating have been used for heating the PCB waste sample and inter-comparison studies have been carried out in order to understand the nature of volatiles and residue obtained during the two different heating processes. GC -MS was used to analyze the volatiles, collected during microwave heating and shows the presence of CO2 as major volatile. Simultaneous TG -DTA -EGA (FTIR) was used in air and inert atmospheres for online analysis of volatiles where CO2 was observed as major volatile in inert atmosphere along with moisture while CO evolution was also confirmed as major evolved gas along with CO2 and moisture in air atmosphere.
