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 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.
KAUST Discovery will host a webinar on solvent-based recycling of lithium-ion batteries. The presentation will be given by Dr. Yaocai Bai, an R&D Staff Scientist at Oak Ridge National Laboratory (ORNL). The talk will explore solvent-based separation processes to efficiently separate electrode materials from metal foils in end-of-life batteries and manufacturing scraps. Why it matters: Battery recycling is a key area for sustainability efforts in the region, as it has implications for energy independence and environmental protection.
KAUST and King Abdulaziz University (KAU) are collaborating to develop low-cost sodium-ion battery technology using fly ash, a waste material from burning fossil fuels. Researchers are purifying fly ash and using thermal treatment to engineer its structure for use as carbon electrodes in batteries. The resulting carbon electrode material is competitive with existing market products and can be used for other applications. Why it matters: This research offers a sustainable approach to energy storage by repurposing waste materials, potentially enabling cheaper and more environmentally friendly grid-scale energy storage for renewable energy sources.
Aramco and KAUST-incubated startup Lihytech are collaborating to develop Direct Lithium Extraction (DLE) technology in Saudi Arabia. Aramco is providing oilfield brines to Lihytech to assess their lithium extraction technology at KAUST Research and Technology Park. The collaboration supports Saudi Arabia's Vision 2030 and its growing demand for lithium in electric vehicles. Why it matters: This partnership could unlock a new critical mineral industry in Saudi Arabia, leveraging existing oilfield resources for sustainable lithium production.
KAUST's Supply Chain Services implemented a Chemical Re-Use Program in February 2016 to encourage researchers to share surplus chemicals. Over 100 researchers have donated more than 3,000 bottles, with over 1,300 bottles reused across multiple divisions and centers. The Enterprise Reagent Manager (ERM) software helps researchers locate available chemicals. Why it matters: This initiative reduces chemical waste, saves costs and time associated with procurement, and promotes environmental sustainability within the university's research ecosystem.
KAUST researchers have developed a new technology for direct lithium extraction from brine in oilfields and seawater, potentially positioning Saudi Arabia as a major lithium producer. The technology, demonstrated at a pilot scale, allows extraction from low-concentration sources (as low as 20 parts per million) without pollutants. It could increase global lithium resources from 22 million tons to over 230 billion tons. Why it matters: This innovation could transform Saudi Arabia from a lithium importer to a producer, strengthening its energy security and influence in the global clean energy market.
International scientists and innovators presented the Circular Carbon Economy (CCE) at UNFCCC COP25, an event organized by the Ministry of Energy of Saudi Arabia and KAUST. The CCE model, promoted by Saudi Arabia, focuses on reducing, reusing, recycling, and removing carbon emissions (4R). KAUST is contributing to the CCE through scientific advances in engineering, chemical, and biological technologies. Why it matters: The CCE framework represents a pragmatic approach to addressing climate change in the region while leveraging technological innovation and natural processes.
