Steel That Breathes: Dr. Shubh Gautam’s Made-in-India Sheets Capture Carbon and Reimagine Infrastructure

Dr. Shubh Gautam's patented colour-coated steel sheets offer a sustainable solution by capturing carbon efficiently, significantly contributing to India's climate action efforts.

India’s growing reputation as a hub for world-class innovation has reached an exciting new chapter. The Government of India has officially granted Patent No. 441784 to Indian inventor Dr. Shubh Gautam of SRISOL–American Precoat Group, for “Novel Nanocomposites and Processes for Making Them.” This pioneering technology introduces colour-coated steel sheets that double as durable building materials and powerful carbon-capturing surfaces, marking a breakthrough in sustainable infrastructure.

Turning Roofs Into Carbon Sinks

At the heart of this breakthrough is a nano-composite polyester-based coil coating developed and perfected entirely in India. When applied to roofing sheets, the coating initiates a remarkable self-sustaining cycle, it continuously captures atmospheric CO₂ day and night, then releases the trapped carbon naturally during rainfall or routine washing. Once cleaned, the surface recharges itself to begin a fresh round of carbon capture, maintaining an endless cycle of sequestration. What was once merely an inert protective layer on steel has now been transformed into a living, breathing carbon sink, marking a powerful Made-in-India contribution to the global fight against climate change.

A Tree-Equivalent Solution That Works Instantly

The scale of its impact is remarkable. A 100,000 sq. ft. warehouse roof fitted with these colour-coated sheets can capture the same amount of carbon as 1,000 fully grown trees. Unlike natural forests, which take decades to mature, these roofs begin mitigating carbon emissions from the very first day of installation.

This makes the technology particularly valuable for urban and industrial landscapes, where space is limited and the urgency for climate action is high. From warehouses and factories to schools and homes, the potential to deploy this innovation across India’s vast building footprint offers a rapid and scalable path to meaningful emissions reduction.

Engineering Excellence Meets Environmental Stewardship

India has long been recognized as a global leader in steel manufacturing and coatings technology. But this breakthrough sets a new benchmark: a material that merges engineering excellence with environmental responsibility.

In an exclusive statement, Dr. Shubh Gautam, Chief Technical Architect Srisol -American Precoat Corporation underscored the broader vision behind the patent: “This is more than a patent, it’s a commitment from India to the world, that our innovation can shelter humanity while healing the planet. By transforming humble roofing sheets into carbon-capturing assets, we are proving that sustainability and industry can thrive together.”

Driving India’s Net Zero 2070 Vision

As India accelerates toward its Net Zero 2070 goal, indigenous innovations like this will be pivotal to mainstreaming sustainable infrastructure. The technology strengthens the Atmanirbhar Bharat (Self-Reliant India) mission and underscores India’s growing role as a global exporter of green technologies.

By embedding climate-positive functionality into everyday materials, SRISOL–American Precoat’s innovation sends a powerful message, sustainability doesn’t have to wait, it can be built right into the structures that shape our lives.

From India, For the Planet

This milestone represents more than a technological breakthrough, it’s a vision of how Indian ingenuity can lead the charge against climate change. As industries and governments worldwide search for scalable solutions, India has shown that innovation born at home can deliver global impact, proving that the path to a greener future can start with something as familiar as a roof over our heads.
