Cooperative research on the recycling of various wastes by a sintering process has been carried out over the last few years. In this study, a porous sintering product was made from a mixture of sludge dredged from Tagonoura Bay, aluminum slag discharged by secondary refining and crushed particles of glass bottles. These were combined in a rotary kiln at about 1100℃. 20 kg sample were put in stainless steel cages and sunk in two different locations on the sea bed in Tagonoura Bay. Adherent organisms were observed for one year. As a result, there were abundant periphton (styela plicate,musseis) and benthos (lugworm) and this suggests that the sea bed may be biologically cleaned. Especially, the cleanup effect is remarkable in the case of the sintering product in which ferrous sulfate was adsorbed.
