Cleaner Bricks Production Case Study # 4 on Utilization of Flyash in Clay Fired Brick Production

In several of the developing countries, fired-clay bricks are the prevalent building materials and are still produced through traditional technologies and practices. Some of these practices have adverse impacts on the environment. Various studies have established that improvements in technology and practices can reduce fuel consumption and pollutants emissions (including black carbon) significantly. The CCAC Brick Production Initiative is aimed at substantial mitigation of emissions of black carbon and other pollutants from brick kilns through employing a range of technology and policy approaches.
The reduction in emissions can be achieved through shifting to efficient brick kiln technologies as well as through production of resource efficient products such as perforated/hollow bricks or flyash-clay bricks (utilizing flyash, an industrial waste, in brick making). This case study is part of a 4-case study series with the objective to showcase the examples of brick manufacturing enterprises who have adopted these measures to improve efficiency and reduce emissions. In this endeavour, case studies on four brick manufacturing enterprises operating in South Asia region have been developed.

These case studies are focused on: 
1. Production of perforated bricks;  2. Production of bricks through Natural Draft Zigzag Kiln;  3. Production of bricks through Hybrid Hoffman Kiln (HHK);  4. Utilisation of flyash in brick making. 

This case study is focused on an enterprise that is utilizing flyash in brick making.
