IIT Jodhpur Turns Waste to Building Blocks

IIT Jodhpur has introduced an innovative technology that converts agricultural residue and plastic waste into construction materials, offering a sustainable solution for the building sector. Assistant Professor Priyabrata Rautray spearheaded the development, resulting in two key products: Bio-Bricks and Agro-Plastic Blocks (APBs).

Bio-Bricks are produced from crop residues like paddy straw and wheat straw. This low-energy process avoids the air pollution associated with traditional kiln firing and results in durable blocks that are carbon-negative. Agro-Plastic Blocks are created by combining agricultural waste with mixed plastic waste, including non-recyclable types, through heating and compression.

These APBs offer robust construction capabilities along with enhanced insulation properties. The technology aims to repurpose waste as a valuable resource, tackling environmental challenges such as stubble burning and plastic pollution in India. IIT Jodhpur has successfully constructed prototype structures, including what it claims is India's first structure built using Bio-Bricks.

The institute is actively developing a housing unit on campus using these materials and plans to scale up the technology for rural housing and infrastructure. This initiative supports the growing demand for affordable housing while promoting environmental responsibility.
