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 researchers cultivated the extremophile microalga Cyanidioschyzon merolae, which thrives in hot, acidic conditions, using commercial fertilizer at lab and outdoor large-scale culture. This was part of the Development of Algal Biotechnology in the Kingdom of Saudi Arabia (DABKSA) project, a collaboration between MEWA and KAUST. The microalgae consume pollutants and CO2 to produce biomass like proteins and oils, which can be used as sustainable animal feed. Why it matters: This positions Saudi Arabia as a potential leader in algal technologies, strengthens food independence, and contributes to the country's carbon net-zero goal by 2060.
KAUST researchers from the Red Sea Research Center (RSRC) and Computational Bioscience Research Center (CBRC) found macroalgae DNA prevalent in the open ocean, up to 5,000 km from coastal areas. 69% of drifting macroalgae sinks below 1,000 m depth, sequestering carbon in deep ocean waters. The study used metagenomes generated by global ocean expeditions Tara Oceans and Malaspina, analyzed via KAUST's DMAP platform and Shaheen supercomputer. Why it matters: The findings confirm the role of macroalgae in carbon sequestration, highlighting their importance in blue carbon assessments for climate change mitigation and underscoring KAUST's contribution to environmental sustainability research.
KAUST has launched a pilot algae facility as part of the DAB-KSA project, in collaboration with the Ministry of Environment, Water and Agriculture (MEWA). The facility aims to produce high-protein algae for animal feed, particularly for fish and poultry, using outdoor ponds and closed tubes. KAUST is positioning itself as a center for algal research, leveraging the Kingdom's resources like sunlight, saltwater, and CO2. Why it matters: This initiative could significantly reduce Saudi Arabia's reliance on imported animal feed and contribute to food security.
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.
