KAUST researchers are exploring novel chemical reactors and separation processes using mathematical design, with a focus on time and shape variables to enhance transport, heat transfer, and mass transfer. By aligning design, modeling, and 3D printing, they create customized shapes with great complexity and less material. This approach allows for the creation of bespoke reactors and separation processes tailored to specific applications, improving efficiency and reducing energy consumption. Why it matters: This research demonstrates the potential of advanced manufacturing techniques to revolutionize industrial design in the Middle East's chemical and pharmaceutical sectors.
KAUST researchers have developed a novel wastewater treatment method that recovers energy while removing ammonium. The process harnesses anammox bacteria to oxidize ammonium and generate electrical current or hydrogen gas. Pilot-scale reactors are being tested at KAUST, coupled with photovoltaic panels for solar-powered wastewater treatment. Why it matters: This approach could lead to more energy-efficient and sustainable wastewater treatment, aligning with circular economy principles.
KAUST researchers led by Pascal Saikaly are developing microbial electrochemical technologies (METs) for wastewater treatment and energy recovery. The team combines METs with membrane filtration, creating a hybrid air-biocathode microbial fuel cell-membrane bioreactor (MFC-MBR) for simultaneous wastewater treatment and ultrafiltration. This system uses an electrically conductive ultrafiltration membrane as a biocathode for electricity generation and passive oxygen transfer. Why it matters: This innovation offers a sustainable approach to water reclamation by reducing energy consumption and producing reusable water, which addresses critical water scarcity challenges in the region and globally.
The Technology Innovation Institute (TII) in Abu Dhabi has launched a Biofoundry to advance R&D in synthetic biology, focusing on genetic engineering, metabolic engineering, and bioinformatics. The facility features high-throughput robotic systems, next-generation sequencing, and advanced computational tools. TII's Biofoundry is now part of the Global Biofoundry Alliance (GBA) to foster partnerships and address shared challenges. Why it matters: This initiative positions the UAE as a key player in synthetic biology, with potential breakthroughs across healthcare, agriculture, and environmental sustainability.
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 researchers have developed an energy-efficient wastewater treatment process that generates high-quality effluent suitable for reuse. A pilot plant in Jeddah, operating since July 2022 in collaboration with MODON, treats 50,000 liters of wastewater daily off-grid, generating 1.5 kWh of electrical energy per 1,000 liters treated. The plant utilizes an anaerobic membrane bioreactor (AnMBR) coupled with UV disinfection, removing up to 99.9999% of microorganisms and producing less solid waste. Why it matters: This decentralized, energy-independent system offers a sustainable solution for water treatment in resource-scarce regions of the Middle East, aligning with Saudi Arabia's sustainability goals.
KAUST's Water Desalination and Reuse Center (WDRC) held a research conference on wastewater treatment from March 27-29. The conference covered innovations in technologies and microbes to recover resources from wastewater. Keynote speakers included Bruce Rittmann, Bruce Logan, and Jurg Keller, with topics ranging from microbial fuel cells to microalgal biotechnology. Why it matters: The event highlights KAUST's focus on sustainable technologies for water management, addressing critical resource challenges in arid regions.
KAUST's algae biotechnology lab, led by Kyle Lauersen, is isolating and characterizing algal species adapted to Saudi Arabia's climate, using 22 bioreactors to simulate different conditions. The team has isolated over 60 strains, building a biobank for Saudi Arabia, and collaborates with a pilot algal facility supported by the Ministry of Environment, Water and Agriculture to produce high-protein algae for aquaculture. They are also determining optimal conditions for algal growth and measuring oil, protein, and carbohydrate production. Why it matters: This research has the potential to advance Saudi Arabia's bioeconomy by leveraging algae for wastewater treatment, animal feed production, and other applications.
