Brickmaking in India is labor-intensive and environmentally damaging, as booming construction clashes with the country's climate goals of carbon neutrality by 2070. To address this, Tarun Jami's startup GreenJams developed Agrocrete, a carbon-negative concrete alternative made from recycled crop residues and industrial waste.

Both innovations face higher costs compared to conventional construction materials but aim to pave the way for sustainable building practices. With global housing demand rising, these efforts highlight the potential for greener solutions to transform the construction industry worldwide.
