A solid burnable fuel composite containing high proportion of dehydrated sludge (60% dried sludge) is presented. Thermo-chemical analyses of coating sludge showed heating and energy values to be 27.88 and 13.20 MJ/kg indicating possible use as fuel source. However, high contents of lead and zinc (2.4 and 38.8 mg/L) depicted deleterious oxides emissions. Hence sludge was pre-treated prior to co-densification with mixed paper waste (MPW). Chemically leached sludge with 5M HNO3 at pH 1.5 recorded maximum lead reductions (below detectable limit), zinc recorded 87.6% reduction. Sludge-paper fire-log glowed with red hot, limited smoke and improved ash content during bench combustibility test.
