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 startup Polymeron is converting date and poultry waste into biodegradable plastics, aligning with Saudi Vision 2030's goals for economic diversification and sustainability. The company aims to process 20,000 tons of waste annually, contributing to a circular economy and creating jobs in polymers, manufacturing, and sales. Polymeron is building its pilot plant at KAUST with support from the National Technology Development Program (NTDP). Why it matters: This initiative addresses plastic pollution and agricultural waste while creating a new industry in the Kingdom, tapping into a global market for biodegradable plastics valued at $13 billion in 2024.
Edama Organic Solutions received $780,000 USD seed investment from the KAUST Innovation Fund. KAUST has also signed a contract to build a commercial-scale composting facility for Edama on its Thuwal campus, with a recycling capacity of 5,500 tons. Edama will manufacture and sell products, including Edama Desert Compost and Edama Palm Peat. Why it matters: This initiative promotes sustainable waste management practices in Saudi Arabia by turning organic waste into valuable soil improvement products tailored for desert environments.
This paper proposes a machine learning method for early detection and classification of date fruit diseases, which are economically important to countries like Saudi Arabia. The method uses a hybrid feature extraction approach combining L*a*b color features, statistical features, and Discrete Wavelet Transform (DWT) texture features. Experiments using a dataset of 871 images achieved the highest average accuracy using Random Forest (RF), Multilayer Perceptron (MLP), Naïve Bayes (NB), and Fuzzy Decision Trees (FDT) classifiers.
A research paper proposes a smart waste management system called TUHR for Makkah, Saudi Arabia, leveraging IoT and AI to handle waste accumulation during the annual pilgrimage. The system uses ultrasonic sensors to monitor waste levels and gas detectors to identify harmful substances, alerting authorities when containers are full or hazards are detected. The proposed system aligns with Saudi Vision 2030 by promoting sustainability and improving public health through optimized waste management.
KAUST researchers are undertaking a project to improve global date palm production and protection by studying the date palm genome, collecting samples from ancient palms near Madinah. They aim to develop new breeding strategies for faster, healthier, and more pest-resistant palms. The research involves advanced genome sequencing and the creation of molecular tools to improve date palm agriculture, including rapid sex determination methods and gene editing. Why it matters: This research is critical for enhancing date production in arid regions like Saudi Arabia, which is a major global producer, and for ensuring food security amidst climate challenges.
KAUST researchers discovered that the red algae strain Galdieria yellowstonesis can convert sugars from chocolate-processing waste into C-phycocyanin, a valuable blue pigment. The study found that high levels of carbon dioxide promote Galdieria growth, and the resulting phycocyanin was deemed food-safe by the U.S. FDA. Mars supported the research by providing chocolate samples. Why it matters: This research offers a sustainable method for waste management and contributes to a circular economy in the region, with potential applications in food, cosmetics, and pharmaceuticals.
KAUST researchers are collaborating with the Saudi Ministry of Environment, Water & Agriculture (MEWA) to develop sensor technology for early detection of red palm weevils. The weevil larvae cause significant damage to palm trees by hollowing them out from the inside. Early detection is crucial because visible signs of distress indicate advanced infection and low chances of rescue. Why it matters: This research aims to protect date farming and crops, which are a vital economic resource for Saudi Arabia and the broader region.
