The leakage of temple waste in the environment surrounding the temples has made the image of temples not only a cultural icon but also a contributor to landfill waste on the island. About 292.36 kg of temple waste is generated from a single ceremonial at Griya Anyar Tanah Kilap Temple. The temple waste consists of 90,16% of organic waste (food, leaf and discarded flower) that is easily biodegraded. This research aimed to examine the temple waste to be recycled into Refuse Derived Fuel (RDF). Leaf and flower waste are used as RDF material using two different drying methods, namely natural drying and pyrolysis. The results showed that the pyrolysis RDF has a similar caloric value to the natural drying RDF with 3311.7 kcal/kg and 2912.7 kcal/kg, respectively. According to the electrical power potential, pyrolysis RDF has 3856.19 kWh/tons, meanwhile natural drying RDF has 3391.59 kWh/tons. The pyrolysis RDF has less organic content and quite higher ash content than the natural drying RDF, making it better quality and appropriate to be applied in the community for a long-term sustainable temple waste recycling.
