Carbonaceous waste used in this project was taken from Ethylene Malaysia Sdn. Bhd. Normally this waste will dispose after send to Kualiti Alam Sdn Bhd. The main aim of this project is to add value of this carbonaceous waste by utilizing its carbon properties possesses by the material. While Li-ion batteries temporarily dampened enthusiasm for capacitor-based storage, demand for power-hungry applications has sparked a resurgence of interest in supercapacitors. The overall market is expected to expand from $208 million last year, to an $877 million market in 2014, according to a new report from Lux Research[1]. Thus, further study was conducted to use carbonaceous waste as supercapacitor. By doing this, the company may get profit and cover all maintenance cost in plant. In this project, the experimental was design to treat the waste for activation carbon purpose. Then, it will be characterized before assemble as supercapacitor. Characterization is important to monitor the structure of carbonaceous waste. The study to treat this carbonaceous material has been carried out. Some of research had been done and literature was collected in order to study the factor that may affect capacitance of carbon. The experiment is divided in 3 part, which is the first part is to do the treatment of carbonaceous waste; the second part is to Characterize the treated carbon and the last part is to use the treated carbon as supercapacitor for performance evaluation. Electrochemical performance of capacitor from commercial carbon and from carbonaceous waste is also compared and evaluated. Further studies could be carried out to optimize the charge-discharge capacity and the efficiency of capacitor using this material. As conclusion, this study has proved that this specific carbonaceous waste is able to act as electrode in electrochemical capacitor with discharge capacity 2.185 mA.h/g and 85% efficiency
