Physicochemical Characterisation and the Prospects of Biofuel Production from Rubberwood Sawdust and Sewage Sludge

This study aims to evaluate the physicochemical properties of rubberwood sawdust (RWS) and sewage sludge (SS) for producing biofuel or liquid products via pyrolysis co-pyrolysis. The chemical thermal both samples were observed have superior bioenergy production capabilities. RWS SS had significantly different properties, such as particle-size distribution, bulk density, ultimate proximate analysis, lignocellulose composition, thermal-degradation behaviour, major minor elements. composition extractives was found only marginally affect end product. Carbon hydrogen content, two main elements enhancement, correlate with organic components (48.49, 7.15 wt.%) (32.29, 4.06 wt.%). a higher elemental iron, calcium, potassium than RWS. Both heating value 13.98 21.01 MJ/kg lower 11.65 17.66 MJ/kg, lesser energy potential that fossil fuels. findings from these blends are relatively moderate due related lignocellulosic composition. novel contribution this research optimize use local waste materials new raw material could serve sustainable fuel source.
