Our Story
As scientists and engineers, we recognise the greatest threat facing humanity today is climate change.
In 2023 we founded earth4Earth to develop a practical solution to combatting global carbon emissions.
Our innovative materials transform buildings into CO₂ absorption systems, helping to mitigate global warming and protect our planet.
Our first product, our e4E bricks, will be available in early 2025. To receive updates please join our mailing list.
Fujian Tulou
The inspiration for our company and our bricks comes from Fujian Tulou, traditional Chinese earth buildings known for their sustainable design and energy efficiency. These structures naturally regulate temperature and are resilient, even to natural disasters.
Fujian Tulou have been constructed since the Ming dynasty hundreds of years ago. These structures were reinforced with bamboo, which have knots similar to the projections (ribs) on ribbed steel rebar. Tulou mostly followed the traditional "closed outside, open inside" architecture, featuring a closed circular wall with living space and an outdoor courtyard at the centre.
Earth-based materials
We have combined this legacy with our scientific research to create earth-based materials to transform the construction industry. Our products are manufactured in Wuhan, China, at a facility led by Dr Lei Zhang, Professor Theodore Hanein, and Professor Yi Luo. Wuhan’s position as a major manufacturing hub supports our plans for continual growth and global outreach.
Properties of Fujian Tulou
Carbon Absorption: The use of natural materials such as rammed earth during construction can contribute to carbon sequestration, helping to reduce the overall carbon footprint.
Sustainable Design: Fujian Tulou are built using locally sourced, natural materials, minimising environmental impact and promoting sustainability.
Temperature Regulation: The unique construction of these buildings allows them to maintain a stable internal temperature, staying cool in summer and warm in winter.
