In the case of solid refuse fuel manufacturing facilities, residues, which are left-over from the process, are buried at a rate of 34% of incoming amount, and some are disposed of by combustion. The residues were upgraded by mechanical biological treatment and subject to attempts at combustion, and the bottom ash generated from combustion tests was applied to fabricate bricks for recycling. The brick was manufactured by substitutions of stone powder, cement, sand ranging from by 3 to 30% according to experimental conditions. These could be used as an interlocking block for the sidewalk or open spaces. The basic characteristics of the bottom ash and the water absorption, bending strength, compressive strength, and dimensions of the mixed bricks were tested. Results showed that 10% of the stone powder substitution was regarded as an optimal condition, and the brick quality was satisfactory under given standards, because the pozzolanic and hydration reactions occurred effectively.
