ClimateCrete, a KAUST spinout, has raised investment for its technology that modifies sand particles to make them suitable for concrete manufacturing. The patented tech reduces the need for cement and lowers CO2 emissions by up to 60 percent. Tests show a significant increase in strength compared to untreated sand. Why it matters: This technology addresses the global shortage of suitable construction sand and supports Saudi Arabia's carbon-neutrality goals by enabling a 100% domestic supply chain for concrete.
The Oil Sustainability Program (OSP), in partnership with PIF, SIRC, NEOM, SIKA, and ClimateCrete, has launched the "NovusCrete" Consortium to innovate in sustainable concrete solutions. The initiative prioritizes localization using materials like seawater, recycled construction waste, and fine sand, supported by entities like the American Concrete Institute (ACI). ClimateCrete, a KAUST spin-off, uses patented technology to transform fine sand into high-quality concrete sand, reducing cement use and CO2 emissions by up to 60%. Why it matters: The consortium and ClimateCrete's technology represent significant steps towards sustainable construction practices in the region, aligning with Saudi Arabia's carbon neutrality goals and fostering a deep-tech startup ecosystem.
KAUST researchers participated in COP28 in Dubai, showcasing environmental research from sustainable construction to coral restoration. Professor William Roberts presented cryogenic carbon capture, while Professor Hussein Hoteit demonstrated carbon dioxide removal and underground hydrogen storage. A KAUST spinout, ClimateCrete™, launched technology to make local sand suitable for concrete, reducing carbon emissions by up to 60%. Why it matters: KAUST's presence at COP28 highlights the institution's role in driving regional climate solutions and fostering public-private partnerships for environmental sustainability.
A KAUST-led team developed a superabsorbent polyacrylate film for passive cooling, combining radiative and evaporative techniques without extra energy. The film uses sodium polyacrylate to absorb moisture and form a reflective film, reducing solar heating. Experiments showed the film lowered temperatures by five degrees Celsius, with simulations indicating a 3.3 percent reduction in total energy consumption. Why it matters: This innovation offers a sustainable alternative to traditional cooling systems, reducing carbon emissions and strain on energy grids in hot climates.
KAUST has released its 2023 SDG Highlight Report, showcasing the university's efforts in advancing the UN Sustainable Development Goals (SDGs). Key projects featured include the KAUST Coral Restoration Initiative and ClimateCrete. The report also highlights the release of KAUST's new Sustainability Policy and the hosting of the Global Sustainability Development Conference. Why it matters: The report signals KAUST's commitment to aligning with Saudi Vision 2030 and integrating sustainability into its research, operations, and engagement with the global community.
KAUST hosted the Future Cement Initiative (FCI) National Workshop, gathering over 200 experts to advance low-carbon cement production in Saudi Arabia. Researchers presented findings on using locally sourced clay as sustainable cement blends, reducing the need for carbon-intensive clinker. The workshop addressed cement decarbonization, circular economy models, and the role of AI in sustainable construction. Why it matters: This initiative supports Saudi Arabia's sustainability goals by modernizing cement manufacturing and leveraging regional resources to reduce carbon emissions in the construction sector.
VentureOne, part of Abu Dhabi's Advanced Technology Research Council (ATRC), launched Nabat, a climate tech venture using AI and robotics for ecosystem restoration. Nabat employs drones, AI-powered software, and flexible seeding to conserve and restore mangroves, aiming to cover thousands of hectares in the UAE over seven years. Their technology enables precision mapping, seeding, and monitoring in remote areas. Why it matters: This initiative showcases the UAE's commitment to using advanced technology for environmental conservation and climate resilience, particularly in preserving vital ecosystems like mangroves, while also highlighting the growing AI startup ecosystem in the region.
