Researchers from King Abdullah University of Science and Technology (KAUST), in collaboration with Universidad de los Andes and others, investigated mangrove ecosystems for enzymes capable of degrading plastics like PET. They discovered that adding agricultural residues to mangrove soils increased the number of potential PET-degrading enzymes and identified a previously unknown group of salt-tolerant enzymes. The team employed metagenomics, artificial intelligence, and 3D structural analysis to study these enzymes, publishing their findings in Nature Communications. Why it matters: This research offers potential new enzymatic solutions for global plastic waste management, particularly for high-salinity industrial applications, by leveraging the unique biodiversity of environments like Saudi Arabia's Red Sea mangroves.
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.
A KAUST-led research team is deploying DNA sequencing technology originally used on the International Space Station to analyze DNA samples in extreme environments along the Saudi Red Sea coast. The portable technology enables on-site extraction, concentration, and sequencing of samples from coral reefs and mangrove forests, minimizing DNA deterioration. Preliminary results indicate a more diverse and complex microbiome than previously found. Why it matters: This application of space-based technology to marine conservation in the Red Sea could provide critical insights into how coral reefs and mangroves adapt to climate change, informing preservation and restoration efforts.
KAUST researchers led by Yves Gnanou and Nikolaos Hadjichristidis have developed a metal-free process for creating aliphatic degradable polycarbonates using CO₂. This polycarbonate is transparent, highly flexible, and produced without toxic metals, using an ammonium compound and a boron-based compound. The process helps reduce plastic pollution and CO₂ emissions, addressing environmental concerns. Why it matters: This innovation offers a sustainable alternative to traditional plastic production, aligning with global efforts to reduce reliance on harmful materials and combat climate change.
KAUST is advancing environmental sustainability and industrial development through catalysis innovation, supporting Saudi Vision 2030's economic diversification and sustainability goals. Researchers are exploring ways to chemically recycle plastic waste and convert carbon dioxide into valuable products. KAUST is building platforms to accelerate the journey from laboratory to market with collaborators, focusing on hydrogen technology and CO2 utilization. Why it matters: This positions Saudi Arabia as a potential global hub for sustainable chemical innovation and clean energy export.
