In this study, pyrolysis of tea waste and the products yielded at the end of the pyrolysis, which is one of biomass sources which has an important place in the renewable energy sources, have been researched. By thermo gravimetric analysis (TGA) of brewed tea waste, thermal decomposition phases were viewed in the nitrogen atmosphere from room temperature to 1,000 degrees C. And then and GC/MS analyses were carried out to make qualitative descriptions of the liquid acquired in the wake of pyrolysis analysis. According to the experiment results, it has been found out that the products can be used as liquid fuel. According to the results of the experiments solid product yielding dropped from 90.85% to 2.95% in line with temperature rise. Moreover, FTIR and GC/MS analyses have proved that the products acquired not only consist of acetone, hydrocarbons, phenol-its derivatives and caffeine but they could be used as liquid fuel as well.
