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 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'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.
Edama Organic Solutions, a KAUST startup, has opened a new organic waste recycling facility in the KAUST Research and Technology Park. The facility is the first of its kind in Saudi Arabia to use technology for waste processing and desert agriculture solutions. It will recycle 100% of KAUST's food and green waste, producing about 4,500 m3 of soil improver. Why it matters: This supports Saudi Vision 2030 by addressing environmental pollution and promoting sustainable agriculture in arid regions, aligning with the Saudi Green Initiative.
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.
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 are using black soldier fly (BSF) larvae to transform organic waste into protein-rich animal feed and high-quality organic fertilizer. BSF larvae consume organic matter and reduce waste volume significantly in a 12-day period. Organic Waste Management Solutions (OWMS), a startup launched by the team, is scaling up and commercializing the BSF-based process. Why it matters: This innovative approach offers a sustainable solution for waste management in the region, generating lower carbon emissions compared to existing technologies like incineration and landfilling.
