Abstract: Each year Thailand produces large amounts of oil palm empty fruit bunch (EFB) as an agroindustrial waste. The majority of EFB waste is simply left in the fields to rot. The Thai government is attempting to use pyrolysis to transform EFB to biodiesel. This produced biodiesel was used for power generation by introducing into a 100 kW diesel generator. The present work assessed pyrolysis technology, including microwave-assisted pyrolysis (MAP), as environmentally sustainable methods of producing biodiesel from EFB. The mass and energy balances of relevant processes were analyzed by using Aspen Plus process design software. Net present value (NPV) was used as indicators of process economics, while CO2 equivalent emission was used as a measure of the environmental impact of the process. The result showed that NPV of CFP and MAP processes were - 1,201,070 and -1,041,965 USD, respectively. For environmental impact assessment showed that the CFP and MAP processes could reduce CO2 emission relative to the current disposal method by 8 and 29 t CO2 eq/yr., respectively. This 100 kW biodiesel power plant promoted the mitigation of global warming potential due to unsuitable EFB waste management. Even this small-scale power plant might not be favorable in terms of the economic aspect, but to achieve the long-term development of society and environments, this can be considered as sustainable technology. Nevertheless, in the case of MAP, the practical development of a continuous-flow MAP process requires extensive further studies relating to optimal conditions of operation and control of microwave heating
