This bio-brick can help cut pollution
Traditional brick kilns dotting countryside are a source of air pollution, though they are essential for supplying bricks to the country’s growing construction industry. Another source of pollution is burning of crop stubbles or agro-waste. A new type of brick – made from bio-waste – promises to address both the problems.
Researchers from Indian Institute of Technology Hyderabad and KIIT School of Architecture, Bhubaneshwar, have developed bricks from agricultural waste products. They have developed a process to use dry waste like paddy straws, wheat straws and sugarcane bagasse to make bricks. It involves chopping the waste to desired size and adding it to lime-based slurry to make homogenous mixture. The mixture is poured into moulds and rammed with a wooden block to make a compact b...
