The thermo gravimetric analysis (TGA) and DTG techniques were used in this study to evaluate the characteristics and pyrolytic kinetic of waste tyres. Decomposition scheme followed was in accordance to the degree of conversion law . The study samples were heated at the rates of 10, 20 and 50C/min. The effective temperatures ranged from 200 to 550C. The activation energy increased as the temperature rose. The highest activation energy was 101.02 kJ/mol, which occurred at temperatures of 310 to 375C at a heating rate of 50C/min.

Key words: Thermogravimetry, waste tyres, pyrolysis potential, kinetics
