Hubei Province, China
Exterior walls
200,000 bricks
~16.4 tonnes CO₂
Demonstrates how everyday infrastructure can help deliver CO2 removal at scale, without changing how buildings are designed or used.
In Hubei Province, China, earth4Earth’s carbon-capturing bricks were deployed in a water treatment project.
The project used 200,000 earth4Earth bricks for its exterior walls.
For a project of this scale, an equivalent quantity of traditional bricks would emit around 520,000 kg CO₂ during production. In contrast, using the earth4Earth bricks delivered net carbon removal of −16,400 kg CO₂.
Throughout their service life, the bricks absorb and permanently store atmospheric CO₂ through natural carbonation. The installed bricks are projected to capture 36.5 tonnes of CO₂, equivalent to purifying 18.25 million m³ of air or the annual carbon uptake of 37.4 acres of forest.

Interior wall cladding / feature wall
4×4 m wall, 1,200 bricks
N10 e4E bricks (10% e4E binder)
~213.6 kg CO₂
Demonstrates carbon-negative, circular masonry in a real workplace setting, within a climate-tech hub designed to showcase innovative sustainable materials.
As part of a refurbishment of Sustainable Ventures’ Manchester offices, earth4Earth supplied 1,200 carbon-negative earth bricks to create a 4×4 metre internal wall cladding installation, nicknamed the “Wonderwall”.
The bricks used for the project were N10, made from excavated soil (diverted from landfill) and stabilised with earth4Earth’s lime-based binder produced via a room-temperature process. In use, the wall continues to absorb CO₂ directly from the air and permanently store it, turning a piece of interior architecture into a small, long-term carbon sink.
Based on the project estimate, each brick absorbs ~0.178 kg CO₂, meaning the full installation is expected to absorb ~213.6 kg CO₂ over time.
