KAUST researchers have developed a surface treatment for jute storage bags to prevent moisture-induced damage to stored grains. The treatment involves roughening the jute surface with an alkali and applying a thin layer of paraffin wax. Experiments showed that seed moisture content reduced by up to 7.5 percent in wax-coated bags, and seed germination efficacy after storage was up to 35 percent higher. Why it matters: This simple, scalable technique could significantly reduce grain losses in developing countries and provide an environmentally friendly alternative for grain storage.
A collaborative research team including KAUST scientists has located a major sink for missing ocean plastic in coastal sediments and mangrove forests of the Red Sea and Arabian Gulf. Core samples showed a pattern of plastic sedimentation aligning with the history of global plastic production since the 1950s. Mangroves efficiently lock up microplastics in coastal soil, with plastic burial rates increasing similarly to global production. Why it matters: The findings highlight the critical role of mangroves in trapping plastic pollution and provide evidence that plastic sedimentation marks the start of a new geological epoch, the Anthropocene.
The Spring 2014 VentureLab showcase at KAUST featured six finalist teams presenting their startup ideas to a panel of judges. The teams had completed an eight-week entrepreneurship bootcamp, interviewing 522 people and undergoing 1,500 hours of training. Trochet, a startup focused on alternatives to plastic bags, won the Most Promising Startup Award. Why it matters: This event highlights KAUST's efforts to foster entrepreneurship and innovation, providing a platform for researchers and students to develop and pitch their ideas.
KAUST community members planted mangrove trees in the university's coastal wetlands as part of the 2022 Winter Enrichment Program (WEP). Mangrove forests are recognized as important carbon sinks, with KAUST hosting a thriving mangrove forest spanning over 110 hectares. The mangrove planting project was initiated to raise awareness of the negative environmental impact associated with travel-related carbon emissions from events like WEP. Why it matters: This initiative highlights the potential of mangrove forests in carbon offsetting and demonstrates KAUST's commitment to environmental sustainability.
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®.
International ocean experts convened at COP25's Oceans Actions Day to discuss ocean and coastal climate actions, emphasizing their role in achieving sustainable development goals. Carlos Duarte, KAUST professor of marine science, highlighted the importance of conserving marine ecosystems like mangroves and seagrasses for carbon sequestration and coastal protection. He also noted Saudi Arabia's interest in promoting ocean and coastal climate actions under its G20 Presidency. Why it matters: The event underscores the crucial role of marine ecosystems in mitigating climate change and achieving global sustainability goals, with KAUST playing a prominent role in research and advocacy.
A KAUST-led team used acoustic technology and net sampling to explore ocean depths in 146 locations worldwide. They found that the biomass of pelagic organisms in the deep sea is much larger than previously thought, especially below productive waters. Deep-sea fauna migrates to shallower areas to feed, transporting carbon to the deep sea. Why it matters: This suggests the ocean's carbon pump is more effective than previously understood, with implications for climate change mitigation strategies.
