KAUST researchers cultivated the extremophile microalga Cyanidioschyzon merolae, which thrives in hot, acidic conditions, using commercial fertilizer at lab and outdoor large-scale culture. This was part of the Development of Algal Biotechnology in the Kingdom of Saudi Arabia (DABKSA) project, a collaboration between MEWA and KAUST. The microalgae consume pollutants and CO2 to produce biomass like proteins and oils, which can be used as sustainable animal feed. Why it matters: This positions Saudi Arabia as a potential leader in algal technologies, strengthens food independence, and contributes to the country's carbon net-zero goal by 2060.
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.
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 have developed new techniques to produce nutritious microalgae in industrial volumes using seawater-adapted Spirulina and Chlorella strains. This innovation eliminates the need for freshwater, making algae-based livestock feed production sustainable and economically viable. The new Saudi Center for Algal Biotechnology Development and Aquaculture will scale up operations from a 1,000 square meter pilot plant to 42,000 square meters. Why it matters: This could help Saudi Arabia decrease its dependency on imported feed and raw food materials, aligning with its Vision 2030 goals for increased domestic food security.
KAUST's Winter Enrichment Program (WEP) 2016 will focus on sustainability with events including lectures from the Governor of SAGIA on science's role in developing sustainable industries in Saudi Arabia, and seminars on climate change featuring international and KAUST experts. A workshop will evaluate freshwater and resource use in the global food supply chain and discuss alternative food production technologies. Dr. Stefan Hindersin will also introduce the world’s first 'Algae House'. Why it matters: This program highlights KAUST's commitment to addressing critical sustainability challenges facing Saudi Arabia and the world through research, innovation, and knowledge sharing.
KAUST, the National Livestock and Fisheries Development Program (NLFDP), and the National Research and Development Center for Sustainable Agriculture (Estidama) are collaborating to explore algae-based biostimulants for agriculture. These biostimulants, derived from marine algae, enhance plant growth and nutrient uptake without the negative impacts of chemical fertilizers. KAUST already operates a commercial-scale algae manufacturing plant capable of producing tons of algae per month for biostimulant production. Why it matters: This initiative positions Saudi Arabia as a leader in sustainable food technology by leveraging algae biostimulants to improve soil health and reduce dependence on imported raw materials.
KAUST researchers, in collaboration with Aeon Collective, have issued a call for global leaders to prioritize land restoration and food systems. Their policy paper, launched at COP16 in Riyadh, outlines a framework for halving degraded land by 2050. The initiative aims to reverse the negative impacts of land degradation, including increased food insecurity and exacerbated climate change. Why it matters: The focus on land restoration at a major UN conference hosted in the Middle East highlights the region's growing role in global sustainability efforts and the importance of addressing desertification.
A KAUST-led study published in PNAS quantifies the potential for increased food supply through coral reef restoration. Analyzing over 1,200 reef sites, the research estimates that rebuilding depleted fish populations could increase sustainable yields by nearly 50%. For Indonesia, this could translate to 162 million additional servings of reef fish annually. Why it matters: The study provides crucial evidence for governments to strengthen food security and ecosystem resilience through fisheries management, especially in regions facing high malnutrition.
