During the impact study of National thermal power plant (NTPC) Kudgi, Vijayapura District, Karnataka in surrounding villages. A unique practice was seen for managing the waste generated from various industries at the local level. Many stakeholders and farmers were engaged in bricks and tile making. We interacted with farmers for their eco-friendly brick and tile making work at the commercial mode in Takkalaki and Gudaini villages. As we know, waste management is a big issue for many industries, such as bagasse from sugarcane industry, fly ash from the thermal power plant, and rice and sugarcane residue from the agricultural field. The fly and bottom ash, collected by the thermal power plant, which was collected by stockholders, farmers, and cement industries directly and transported by trucks to their farm. Stockholders and farmers also receive the bagasse and rice residue from their respective places of origin. All the collected raw materials are used in brick-making by several steps such as clay preparation, moulding, drying, firing, and cooling in brick kilns.

All the waste materials are brought at the location where bricks making take place. They prepare biochar from bagasse and rice residue and store it for further utilization. Brick making starts with preparing a suitable slurry by using these ingredients, as mentioned above, in a specific manner. The combination of bagasse ash, rice straw ash and fly ash varies from 5-20% with clay soil (80-95%). Mainly bagasse ash and rice straw ash is used for their non-sticky properties with brickmould. The fly ash can be mixed up to 5% level during the making. Farmers bring the clay soil from the Almatti dam situated on Krishna River and fly ash from NTPC Kudgi. Prepared bricks were sold Rs. 5 per piece. It is experienced, as a success, and eco-friendly integrated approach of the utilization of bagasse ash, rice straw ash, and fly ash. Adoption of this new approach will be helpful to boost the rural economy and to open a new door for sustainable environmental management of waste material in an appropriate manner to minimize the harmful effects on humans and the ecosystem.
