Utilization of Crude Glycerol Waste from Biodiesel Production as an Additive to Improve the Quality of Tea Dreg Biopellet

Biodiesel production using the transesterification method generates a large amount of crude glycerol as by-products. Crude waste can be reused and utilized an additive in formulation biopellet. Tea dregs are produced by beverages industry that used green fuel form biopellet environmentally friendly energy source. This study aims to analyze characterize from tea with increase quality. The contains six levels composition percentage: 0% (as control), 5%, 10%, 15%, 20%, 25%. parameters for quality assessment refer SNI 8675:2018 standard. best was obtained 10% treatment properties density value 0.93 g/cm3, pellet durability 98.09%, moisture content 8.10%, volatile matter 73.37%, ash 6.08% calorific 16.38 MJ/kg. addition up has been shown improve Keywords: Additive, Biopellet, glycerol, dregs.
