Pakistan is currently facing major energy crisis, so researchers are trying to develop energy efficient methods such as co combustion of waste tyres. Co-combustion referred as an easier and most beneficial procedure of utilization of waste/biomass for energy conversion and interchange of fossil fuels. Thermogravimetric analysis (TGA) of samples with various fractions was used for Kinetic investigations of coal to waste tires Both, isothermal and nonisothermal practices has been investigated, in which subsequent steps of combustions such as drying, devolatization and combustion. Various experiments of TGA were carried by heating rates of 20°C/min, 30°C/min and 40°C/ min. The loss of weight loss was calculated by using standard kinetic model (Volumetric Model VM).
