We're a climate-tech company making low-carbon, climate-resilient construction materials from the city's waste.
To cut the carbon out of construction, and build the climate-resilient, circular materials our cities need for the decades ahead.
Construction sits where three crises meet.

of days in early 2024 brought extreme weather to India.
of India's construction waste is recycled.
Low carbon. Climate resilient. Circular.
No kiln, no cement, no quarried stone, and plastic kept out of open fires.
Resistant to weather, water, wear and corrosion. Suited to coastal and heavy-rain regions, and quick to lay for relief housing.
Plastic and construction waste become materials that last, instead of filling drains, dumpsites and the sea.
Plastic waste from the city's homes and markets.
Construction waste from building sites across the city.
Two of a city's hardest wastes, turned into walling and paving that lasts.
A drop-in replacement for fired clay brick, laid just the way masons already work.
Feature walls, driveways, courtyards and plazas.
Walling, paving and tiles are where we start. Custom moulds for everything else.
Indicative projections for the next 10 years.
For builders, architects, home owners and public agencies.
Low-carbon, climate-resilient and made from waste. Walling, paving and tiles are where we start. Standard in black, red on request.
Six interlocking shapes in three duty grades. Pick one to see it.
Duty grades are subject to IS 15658 testing.
Even early pilot samples came in at roughly three to six times the minimum Indian Standards set for common walling materials.
Grey bars show the minimums in IS 2185 and IS 1077.
Suited to harsh and coastal environments.
Less weight on the frame and on the truck.
Sizes, shapes and thicknesses made to your drawings.
Lower embodied carbon, credits for green buildings, and a lawful home for the city's waste.
Buildings and construction produce 34% of global CO₂. Cement and steel alone account for 18%. Walling is where much of that carbon is locked in.
Embodied carbon is everything released before a wall stands. Conventional walling has four big sources.
India's brick kilns burn about 35 million tonnes of coal a year.
Making clinker releases roughly its own weight in CO₂e. It binds concrete and AAC blocks.
Laterite is cut from hillsides and heavy to move.
About 5.8 million tonnes of plastic are burned in the open in India each year.
Cradle-to-gate, kg CO₂e per kg of material.
Gatta products avoid all three: no kiln, no cement binder and no quarried stone.
tonnes of CO₂e over the next 10 years
Each tonne of waste we put to use keeps plastic out of a fire and replaces a fired brick or quarried stone. Figures use conservative emission factors.
Indicative. Annual impact statements follow the GHG Protocol and ISO 14064.
For architects, consultants and developers working toward a green rating or a lower embodied-carbon target.
Materials with recycled content. Green Homes awards up to 2 points at 10% and 20% recycled content.
Recycled content. Post-consumer plus half of pre-consumer content, at 10% or 20% of material value.
Low-impact and recycled materials. Waste-based walling with no kiln firing or quarrying.
Value-chain disclosure. Waste-diversion and carbon data for listed developers' reports.
Less dead load on beams, columns and foundations.
Resistant to weather, water, wear and salt air.
Supports regional-material credits and cuts haulage.
For rating submissions and waste-rule compliance.
Waste diverted and emissions avoided per order.
From NABL-accredited labs, to your QA spec.
Environmental Product Declarations, coming for core products.
Since 1 April 2026, India's waste laws ask builders and cities to recycle more and dump less. We help them do it.

of it recycled.
Large projects now carry extended producer responsibility, and a growing share of construction material must be recycled. Producers can also meet targets by buying certificates from registered recyclers.
Minimum recycled material in construction
Producers' own construction waste recycled
Waste is split into four streams, waste facilities must be registered and audited, and landfills are limited to inert, non-recoverable waste. Dry-stream plastic needs somewhere to go.
That puts waste-based building materials firmly inside India's recycling economy.
Products and paperwork that count toward recycled-content targets.
Put to use instead of dumped on roadsides and wetlands.
Plastic that would otherwise be burned or dumped, turned into building materials.
Waste-diversion and carbon data for EPR, audits and impact reporting.
Gatta Tech is a climate-tech, sustainable construction materials company. We turn the city’s waste into low-carbon, climate-resilient materials, cutting emissions in construction and keeping waste in a circular economy.
Our cities have built with quarried stone and fired brick for generations. We want the next generation of buildings to rise from material the city has already thrown away.
The city's plastic waste and construction waste become our raw material, so the city gets cleaner and builders get cheaper walls.
To cut the carbon out of construction, and build the climate-resilient, circular materials our cities need for the decades ahead.
Turn the city's plastic and construction waste into low-carbon, climate-resilient construction materials that cost less than what they replace.
Lower embodied carbon in every wall and floor.
Materials that hold up to heat, rain, salt air and wear.
Waste kept in use as infrastructure.
Priced below the materials we replace.
Impact reported transparently, using recognised methods.
Sourced and made locally, for the coastal climate we live in.
Each tonne in is a tonne kept out of a drain, a dumpsite or a fire.
