Case Studies

---

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.

• Location: Sustainable Ventures offices, Sister Renold Building (Manchester)
   
• Application: Interior wall cladding / feature wall
   
• Scale: 4×4 m wall, 1,200 bricks
   
• Product: N10 e4E bricks (10% e4E binder)
   
• Why it matters: Demonstrates carbon-negative, circular masonry in a real workplace setting, within a climate-tech hub designed to showcase innovative sustainable materials.
