Kinetics and thermodynamics study of organic waste combustion using thermogravimetric analysis

Urban waste in Malang becomes a significant problem due to its increasing volume and negative impact on the environment. An incineration process offers solution reduce waste. The thermochemical method is one of routes effectively. This paper discussed combustion organic with thermogravimetric analysis nonisothermal mode which temperature escalated from 25 1000°C by heating ramp 20°C/min. burning divided into three steps decomposition, namely step moisture loss, decomposition volatile matter fixed carbon, final ash residual matters. kinetic parameters calculated using Coats-Redfern at main step, resulting activation energy 99.37 kJ/mol pre-exponential factor 6.01E+08/s.
