In this study STP sludge and sugarcane press mud is used as a replacement material for fly ash brick. This study is done to reduce the STP sludge and sugarcane waste dumping in the earth to protect the environment from hazardous and also increment of low-cost brick towards the construction industry for the sustainable development. Bricks are the building material used for the construction of walls, pavements and other constructions. In previous days mud blocks were being used in construction but now clay bricks are used. While manufacturing the clay bricks the Carbon dioxide emission is more. Many attempts have been made to overcome these problems. So the industrial waste materials and the by products are used in the manufacturing of bricks. Here we have used the municipal sewage treatment plant sludge (STP) and the sugarcane waste produce i.e. press mud with fly ash and lime so that we get the binding and compressive strength in good amount. Here the bricks are done without burning, so the greenhouse gas emission is minimized. The press mud is a material which is obtained from the clarification of sugar. The disposal of this waste into the environment causes the land pollution so this study will be a better solution for this problem. The municipal sewage sludge and sugarcane press mud are added at different percentages such as 10, 15, 20 and 25.
