    Municipal Solid Wastes (MSW) has great potential as a clean, renewable feedstock for producing modern energy carriers through thermochemical process, called pyrolysis. However, despite their enormous potential as energy sources, their thermal characteristics are still not well known. Moreover many researches just pay a little attention on MSW from developing countries, for example Indonesia MSW contains some indigenous wastes such as bamboo and banana leaves wastes, therefore this paper tries to show the slow pyrolysis characteristics of Indonesian MSW. Investigations on behaviors of segregated MSW slow pyrolysis have been conducted using macro balance apparatus. Four components of segregated MSW (bamboo wastes, banana leaves wastes, snack wrap wastes and styrofoam wastes) and their blends were pyrolised and then thermogravimetry analysis has been done and their characteristics such as pyrolysis profiles and activation energies, were analysed and calculated. About 20 grams of samples were pyrolysed under 100 ml/min N2 at constant heating rate of 10 °C /min from room temperature to 400 °C final pyrolysis temperature and then the temperature of samples were kept constant for 30 minutes. The nitrogen flow serve swept gas which ensures an inert atmosphere during the pyrolysis test. In order to indentify pyrolysis characteristics of the samples, thermogravimetry analysis was performed. The recorded data were weight losses and sample temperatures during the pyrolisis process. The results of the research showed that bamboo wastes and banana leaves wastes could be categorized as low stability organics, while snack wrap wastes could be categorized as polymer mixture materials and styrofoam wastes could be classified as plastic materials. Meanwhile profiles of blends materials pyrolysis followed the characteristics of their single components which is indicated by peak temperature. This study also found that global kinetic method could calculate the pyrolysis activation energy.
