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.

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.
This project used 200,000 earth4Earth bricks and was assessed over a 20-year lifecycle. The result is a lifecycle net carbon removal outcome, combining low-impact manufacture with ongoing CO₂ uptake during service life. Construction has historically been a major source of emissions. This pilot shows a credible pathway for the sector to become actively climate-positive, with masonry products that remove and store CO₂ while meeting real-world project demands.
For a project of this scale, an equivalent quantity of traditional bricks would emit around 520,000 kg CO₂ during production. In contrast, producing the earth4Earth bricks delivered a carbon removal of −16,400 kg CO₂, demonstrating a step change in embodied impact. Throughout their service life, the bricks adsorb and permanently store atmospheric CO₂ through natural carbonation. Over the 20-year lifecycle, 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.
At end of life, the bricks can be crushed and recycled into agricultural soil, eliminating construction waste and supporting circular-economy outcomes aligned with “polluter pays” principles.
