Pyrolysis kinetics of a kind of printed circuit board waste was investigated under various conditions with thermogravimetry (TG) in the present work. The dynamic thermogravimetric analysis curve and its derivative were analyzed to obtain information on the kinetic parameters. The data from experiments were processed to determine the pyrolysis mechanism of printed circuit board and the kinetic parameters such as activation energy E(kJ/mol) and pre-exponential factor A(1/min). A tube-type apparatus was used to pyrolyze printed circuit board waste under different conditions，and the products were analysised by using FTIR and EPMA.
