Manufactured in Wuhan, China, earth4Earth aims to shift production to the UK by 2026 to minimise the carbon footprint associated with international transport

Sheffield-based startup earth4Earth has introduced a pioneering line of eco-bricks that actively absorb and permanently store carbon dioxide from the atmosphere without emitting CO₂ during production.

Unlike traditional bricks that require energy-intensive firing, these eco-bricks are made using recycled soil excavated from construction sites and a proprietary binder that sets at ambient temperature. This process not only eliminates the need for high-heat kilns but also enhances the bricks’ structural strength and their ability to capture atmospheric carbon.

Currently manufactured in Wuhan, China, earth4Earth aims to shift production to the UK by 2026 to minimise the carbon footprint associated with international transport.

At the end of their lifecycle, the bricks can be crushed and reused either as raw material for new bricks or as a soil-enriching fertilizer completing a sustainable, circular loop.

John Grant, a climate expert at Sheffield Hallam University, praised the innovation, highlighting the urgent need for low-carbon construction materials. He noted that while the technology holds significant promise, its real world impact will depend on the bricks’ long-term durability and strength.

With their low-emission manufacturing, carbon-sequestering properties, and recyclability, earth4Earth’s eco-bricks mark a promising step toward net-zero buildings and a more climate-resilient construction industry.
