GreenJams cuts cement carbon footprint 80% with carbon-negative Agrocrete blocks

GreenJams founder Tarun Jami explains how the company's Binder reduces cement's carbon footprint by 80 percent. Their Agrocrete blocks are carbon-negative, meaning they can bring the net embodied carbon of walls to zero and offset emissions from high-carbon materials like RCC and aluminum facades. For developers, this offers a practical way to lower embodied carbon at the material level. Walling makes up a large share of a building's material footprint, so switching to carbon-negative blocks can significantly reduce overall project emissions without changing structural design.

80 percent cut in cement carbon footprint is significant if the Binder scales. Agrocrete being carbon-negative for walls could offset RCC emissions. But I want to see the full lifecycle numbers.

Agreed. Claiming carbon-negative is one thing, proving it with a third party verified LCA is another. The article mentions Agrocrete offsets high carbon elements, but what is the binder made from?

If the binder is agro waste based, that could be real carbon storage. But the scale question matters. How many tons of Agrocrete can they actually produce per year for Indian construction?

The policy angle here is whether these materials qualify for green building credits or carbon offset programs. India's construction sector needs clear standards for embodied carbon accounting.

Practical question: what is the cost per square foot compared to standard AAC blocks or clay bricks? Developers will not switch unless the price is competitive or there is a regulatory push.
