Dubai-based startup ARDH Collective has developed DuneCrete, a concrete alternative made from locally sourced desert sand that reduces cement content by 50%. The innovation addresses the construction industry's massive carbon footprint by using abundant regional materials instead of importing them.
Why Construction Needs a Green Overhaul
Construction is responsible for 34% of global CO₂ emissions, according to the International Energy Agency. The problem lies largely in materials: producing one ton of Portland cement emits between 0.6 and 0.8 tons of CO₂ due to energy consumption and the chemical reaction itself.
Any idea to replace classic building materials like concrete and brick is therefore welcome for decarbonizing the industry. Alternatives such as beach shells have been explored, but ARDH Collective's approach is different: instead of importing materials, they manufacture with resources abundant in the region—specifically, sand and date seeds.
What Is DuneCrete?
DuneCrete is the flagship product of ARDH Collective, a Dubai-based company founded by Alhaan Ahmed, Alyina Ahmed, and Máximo Tettamanzi. It is a concrete alternative made from locally obtained desert sand that cuts cement content by 50%.
From this material, the company produces DuneBlock, building blocks for construction. Their product catalog also includes Dateform, a material that reuses 1,000 date seeds per square meter.
Key Takeaways
- DuneCrete reduces cement content by 50% compared to traditional concrete.
- It uses desert sand, a locally abundant resource in the UAE, avoiding imports.
- The product line includes DuneBlock for construction and Dateform, which reuses date seeds.
- Construction accounts for 34% of global CO₂ emissions, making material innovation critical.
- ARDH Collective is a Dubai-based startup founded by Alhaan Ahmed, Alyina Ahmed, and Máximo Tettamanzi.
How DuneCrete Compares to Traditional Concrete
| Feature | Traditional Concrete | DuneCrete |
|---|---|---|
| Cement content | Standard (100%) | Reduced by 50% |
| Sand source | Often imported or mined from riverbeds | Local desert sand |
| CO₂ emissions from cement | 0.6–0.8 tons per ton of cement | Significantly lower due to reduced cement |
| Additional materials | Aggregates, water, admixtures | Date seeds (in Dateform product) |
Who Benefits and What It Means
The construction industry in the UAE and beyond could benefit from DuneCrete. By using local desert sand, the need for imported materials is reduced, lowering both costs and emissions from transportation.
Moreover, the reduction in cement content directly addresses the most carbon-intensive component of concrete. This could help builders meet sustainability goals and regulations aimed at reducing embodied carbon in buildings.

What to Watch Next
As ARDH Collective scales up, questions remain about the performance and durability of DuneCrete compared to traditional concrete. The company will need to demonstrate that its product meets building standards and can be produced at competitive prices.

Anyone following the wider picture can start with August Solar Eclipse in Spain: Rural Tourism Safety Rules for Visitors. The same theme surfaces in China's New Naval Monster: The Semi-Submersible Crane That Sinks to Work, which takes a different angle.
If successful, DuneCrete could serve as a model for other regions with abundant desert sand, turning a perceived liability into a valuable construction resource.

A companion piece, Dubai's DuneCrete: Desert Sand Concrete Cuts Cement by 50%, approaches the same subject from another angle.
FAQ
What is DuneCrete?
DuneCrete is a concrete alternative developed by ARDH Collective that uses locally sourced desert sand and reduces cement content by 50%. It is used to make building blocks called DuneBlock.
How does DuneCrete reduce carbon emissions?
By cutting cement content by 50%, DuneCrete reduces the CO₂ emissions associated with cement production, which emits 0.6–0.8 tons of CO₂ per ton. Using local sand also avoids emissions from transporting imported materials.
What is Dateform?
Dateform is another product from ARDH Collective that reuses date seeds—1,000 seeds per square meter—as a sustainable building material.
Who founded ARDH Collective?
ARDH Collective was founded by Alhaan Ahmed, Alyina Ahmed, and Máximo Tettamanzi. The Dubai-based startup focuses on sustainable construction materials.
