Abstract- Biodegradable solid waste in the form of waste dumps or as a waste effluent in rivers is a major source of pollution in India creating severe environmental problems. This biodegradable solid waste can be a breeding ground for pests and diseases in waste dumps, could create a large amount of greenhouse gas emission upon burning and may even lead to blockage of the drainage system if discharged along with sewage. One of the solutions to this problem is to use this waste in the form of biochar. The use of biochar as a building material helps in carbon fixing this waste in buildings and can pose as a viable solution for the infrastructure sector, which could be instrumental for protecting the environment to a greater extent and positively influence human life. In the past years, a great deal of research has been done on eco- friendly and green building materials using recycled raw byproducts and wastes. This study examined the possibility of making clay bricks from biochar, which was formed using the putrescible waste produced at homes, with partial replacement of clay. Sample of the waste used for the formation of biochar mainly consisted of food wastes or garden wastes and the biochar formed was crushed into powdered form and sieved through a 75 micron sieve. Biochar having considerable plasticity index was used directly without any additives. The bricks were made in increments of 5% biochar concentration up to a total of 20%. The bricks formed using more than 20% biochar concentration were rejected as cracking was observed in the brick samples. The bricks were termed as biochar – clay bricks. 25 biochar – clay bricks for each increment were formed. The biochar – clay bricks were sundried and then fired in a kiln at different temperatures. The quality of bricks was analyzed for compressive strength and dimensional tolerance. The biochar – clay bricks were cured and their corresponding characteristic compressive strength was determined. The bricks with 5% by weight biochar – clay composition and 15 day curing were found to be most suitable.
