Abstract The effect of different extraction solvents (polar and non-polar) on yield, chemical and physical properties, including free fatty acid content (FFA) or acid value (AV), saponification value (SV), density, viscosity, elemental composition and heating values of oil extracted from spent coffee grounds (SCG) is investigated. The Soxhlet extraction method is utilized for the extraction of oil from spent coffee grounds. Iso-propanol, ethanol, and acetone as polar solvents and toluene… CONTINUE READING
