Waste may be defined as an unwanted material generated after the manufacturing process from industry, agriculture, or household activity. Waste causes many nuisances in the environment. It produces many types of infection, for humans and animals. The sludge from tannery effluent plants has the problem of disposal. Dewatered sludge is disposed of by landfilling. However, it is not an appropriate solution, due to the land limitation. The production of sludge in tannery effluent plants is about to increase every year. In addition, the constraint to treat sludge is very high in cost and time-consuming, which is a disadvantage to the responsible parties. Therefore, this study was carried out to utilize the sludge waste (SW) produced from the tannery effluent plant as a brick. The sludge brick (SB) mixtures were incorporated with many ratios of SW. Tests were conducted such as fineness test, specific gravity, water absorption, and compressive strength. In conclusion, brick with 20% utilization of SW is acceptable to produce good quality brick. This study shows that the disposal of tannery sludge TSW would act as a suitable material for manufacturing bricks with proportionate mix and design.
