In this study, the physical and combustion properties of briquettes produced from a blend of palm oil mill sludge (POMS) and rice husk were investigated. The POMS was blended with rice husk in the ratios of 1:10, 1:5, 3:10, 2:5, 1:2, 3:5, 7:10, 4:5, 9:10, and 1:1. The result showed that the increased addition of palm oil mill sludge in rice husk sample significantly influenced (p < 0.05) the physi...... hiện toàn bộ
