Proximate Analysis and Calorific Value of Pellets in Biosolid Combined with Wood Waste Biomass

In this study, biosolid and wood waste biomass were used as fuel by turning them into fuel pellets. The purpose of making fuel pellets with various compositions was to compare the type of biosolid pellets and wood waste in terms of proximate testing. The benefits of making biosolid pellets can reduce the landfill waste that contributes to the environmental pollution. The results of this research showed the highest water content that is equal to 10.07% was found in the wood waste pellets with the composition of (90: 10; the highest ash content, amounting to 33.19% was found in the pellets with the composition of (50: 50); the highest value of volatile substances (74.05%) was contained in pellets with the composition (90: 10); the highest value of solid carbon (10.13%) was found in the pellets with the composition of (80: 20) Meanwhile, the highest calorific value was exhibited by the pellets with the composition of wood waste and biosolid (90: 10), equalling 3.822 cal/g.
