Optimization of Refuse Derived Fuel (RDF) of solid waste in palm starch home industry through the variations of binder materials

Abstract

A lot of energy consumption and the abundance of waste stimulate various alternative energy from biomass. One of the biomasses that has not been widely used is palm starch waste. Palm's starch home industry in Indonesia produced solid waste that could be converted to synthesis gas through the gasification process. Production of palm starch increases in 2019, gives rise to accumulation waste, causes various diseases, and damages the environment, requiring specific handling. This study investigated the effect of binder material of RDF on palm starch waste. The variations of binder materials used tapioca, rice flour, and mangosteen peel. RDF of palm starch waste with variations of mangosteen peel binder produces the highest calorific value than starch and rice flour, 4009.62 cal/gr. However, RDF with tapioca flour binder has the highest volatile content, so that it can ignite and burn better than rice flour and mangosteen peel binder.
