KAUST researchers discovered that the red algae strain Galdieria yellowstonesis can convert sugars from chocolate-processing waste into C-phycocyanin, a valuable blue pigment. The study found that high levels of carbon dioxide promote Galdieria growth, and the resulting phycocyanin was deemed food-safe by the U.S. FDA. Mars supported the research by providing chocolate samples. Why it matters: This research offers a sustainable method for waste management and contributes to a circular economy in the region, with potential applications in food, cosmetics, and pharmaceuticals.
KAUST startup Polymeron is converting date and poultry waste into biodegradable plastics, aligning with Saudi Vision 2030's goals for economic diversification and sustainability. The company aims to process 20,000 tons of waste annually, contributing to a circular economy and creating jobs in polymers, manufacturing, and sales. Polymeron is building its pilot plant at KAUST with support from the National Technology Development Program (NTDP). Why it matters: This initiative addresses plastic pollution and agricultural waste while creating a new industry in the Kingdom, tapping into a global market for biodegradable plastics valued at $13 billion in 2024.
KAUST researchers have developed a system to convert captured carbon dioxide into industrial-grade ethylene using a high-pressure electrolyzer. The system operates under realistic industrial conditions and uses captured, high-pressure CO₂. It reduces the energy cost of producing ethylene by 0.8 gigajoules per metric ton compared to existing electrolysis systems. Why it matters: This innovation presents a direct path for transforming greenhouse gas emissions into valuable chemical products, aligning with Saudi Arabia's circular economy goals.
Juveiriah Ashraf from the Advanced Materials Research Center (AMRC) graduated from Masdar's Women in Sustainability, Environment, and Renewable Energy (WiSER) program. The program focuses on positioning women as drivers of change across the sustainability debate, covering topics like green hydrogen and food security. Ashraf emphasized the need for a holistic approach involving government, corporate leaders, and financial boards to accelerate sustainability impact through incentives and circular economy adoption. Why it matters: This highlights the UAE's focus on empowering women in STEM and sustainability, aligning with national goals for a sustainable future.
KAUST is collaborating with Coastline Company to convert Red Sea seaweed, specifically Sargassum, into valuable commodities. This initiative addresses the environmental hazard of decomposing seaweed blooms and promotes local employment and a circular economy. KAUST is exploring the use of Sargassum to produce fabric raw materials, alginate for food, biostimulants for agriculture, and fucoidans for therapeutic applications, processing it in a biorefinery manner. Why it matters: This project aligns with Saudi Arabia's sustainability priorities and demonstrates the potential of marine biomass in various industries, including fashion through collaboration with the Saudi Fashion Commission and PYRATEX®.
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.
KAUST researchers have developed a technology to convert spoiled dairy and fruit beverages into valuable short-chain and medium-chain carboxylic acids (SCCAs and MCCAs). These acids can be used for animal feed, aviation fuel, and pharmaceuticals, with SCCAs valued at $300 per ton and MCCAs having 10x higher value. A pilot study is underway at KAUST, utilizing over 500 liters of waste per week from regional companies. Why it matters: This innovation supports Saudi Arabia's goal to eliminate 90% of landfill waste by 2040 and promotes a circular economy by transforming food waste into high-value products.
KAUST is advancing the circular economy through research and collaborations focused on resource efficiency, waste minimization, and sustainability. Researchers are exploring carbon capture, sustainable fuel development, and AI/ML to accelerate circular principles. The university is also working on optimized waste-to-energy conversion, biomass waste conversion, and CO2 conversion for sustainable fuels. Why it matters: This highlights KAUST's commitment to sustainable solutions, which could position Saudi Arabia as a leader in circular economy practices and reduce its reliance on fossil fuels.
