Saudi Arabia faces one of the most severe water scarcity challenges globally due to its extremely arid climate, limited freshwater resources, and a rapidly growing population that is projected to surpass 47 million by 2025, according to figures by the World Health Organization (WHO). According to recent figures by the General Authority for Statistics (GASTAT), the water sector in the Kingdom witnessed significant shifts in 2023, with a 31% rise in desalinated seawater production, now comprising 50% of the Kingdom’s distributed water supply.
With groundwater resources depleting and the per capita household water consumption declining from 112.8 liters per day in 2022 to 102.1 liters in 2023, the Kingdom’s investments in desalination and reuse technologies underscore its commitment to long-term water security.
These conditions have positioned water security and sustainable agriculture as critical priorities aligned with Saudi Vision 2030's sustainability goals. Thus, nanotechnology startups emerged as pivotal players in addressing water and agricultural challenges in Saudi Arabia. They leverage advanced nanomaterials and nanoscale innovations to transform water treatment, wastewater recycling, desalination efficiency, and precision agriculture techniques.
By offering promising solutions to optimize water use, improve crop yields, and reduce environmental impact, these startups help Saudi Arabia move toward a water-secure and food-secure future amid harsh natural conditions and growing demand.
Overall, the nanotechnology market in Saudi Arabia is projected to hit $1.1 billion by 2033, showing a compound annual growth rate (CAGR) of 27.30% between 2025 and 2033, according to recent analytics by the IMARC Group.
Nanotechnology in water management
Nanotechnology companies and startups in Saudi Arabia develop cutting-edge nano-enabled filtration and purification technologies that significantly enhance efficiency and sustainability. Such technologies employ nanomaterials and nanostructured membranes designed at the molecular level to capture contaminants more effectively than conventional systems.
The nano-enabled systems minimize energy consumption, up to 80% less compared to traditional treatment plants, and drastically reduce operational footprints by 90%. They also eliminate odors and chemical residues, making treated water safe for reuse in agriculture, industry, and municipal applications.
For instance, the Ras Al-Khair Power and Desalination Plant stands as the world’s largest hybrid desalination facility, producing both electricity and desalinated water. By integrating nanotechnology in its desalination process, the plant became a model for sustainable water management. Advances in graphene oxide-based nanomembranes are expected to increase the plant's efficiency, reducing energy consumption while improving the purity of the desalinated water.
Additionally, the Saudi Water Authority recently registered a patent for increasing magnesium levels in drinking water using nanotechnology, a pioneering step that strengthens innovation leadership and promotes sustainability. This achievement is expected to enhance the circular economy, promote resource sustainability, and reduce costs.
Germany’s GI Aqua Tech is one of the leading providers of innovative wastewater treatment solutions in Saudi Arabia. It operates on an innovative pay-per-cubic-meter business model through its subsidiary GI Water as a Service (GI WaaS), enabling accessible and cost-efficient on-site treatment solutions without the need for costly infrastructure. This model supports the circular economy and sustainability goals under Saudi Vision 2030 by maximizing water resource efficiency and combating desertification. Getting its patented G-Nano technology certified by the Saudi authorities, GI Aqua Tech became a pioneer in sustainable wastewater management. This technology reduces energy consumption by 80%, cuts operational footprint by 90%, and eliminates odors, making it highly efficient and eco-friendly.
Another key player is Separation Membranes Innovation (SMI), a Saudi startup specializing in developing and manufacturing high-quality water treatment membranes locally. It utilizes the latest advancements in materials nano-science for superior membrane performance.
Founded by Saudi researchers and entrepreneurs with deep knowledge of water treatment technologies, SMI provides innovative, high-quality, locally manufactured water treatment membranes and pioneering solutions to address water scarcity challenges across the Middle East and beyond, while establishing Saudi Arabia as a hub for water treatment innovation.
By incorporating real-time monitoring and automation, these companies enable scalable plug-and-play solutions that can be tailored to different sectors, from oil and gas to urban wastewater.
Desert Farming
Recent reports by GASTAT revealed that agriculture remained the largest consumer of water, using 12,298 million cubic meters. However, non-renewable groundwater consumption by the agricultural sector dropped by 7% to 9,356 million cubic meters, compared to 10,044 million cubic meters in 2022.
Saudi nanotechnology companies and startups utilize precision agriculture tools and smart solutions to optimize resource use and improve crop productivity. These companies embedded nano sensors in the soil and plants, enabling real-time monitoring of soil nutrients, moisture levels, and plant health with unprecedented accuracy. The sensors act as an intelligent nervous system for farms, allowing precise, data-driven irrigation and fertilization that reduces water waste and enhances crop yields in the arid Saudi environment. Other innovations, such as nano-enabled fertilizers and pesticides, were designed to release nutrients slowly and target crops more effectively, minimizing chemical runoff and environmental impact.
For desert farming, some startups integrate nanotechnology with IoT and renewable energy, supporting controlled environments like solar-powered greenhouses that cultivate salt-tolerant, water-efficient crops compatible with Saudi Arabia’s challenging soil and climate. Key players in this field include iyris, Saudi Desert Control, Arable, Saudi Arabian Hydroponic Company (Zarei), and GreenMast. Research institutions like King Abdullah University of Science and Technology (KAUST) also contribute to achieving sustainable agriculture and food security by developing nanotech solutions and improving plant growth and resilience adapted to desert conditions.
The role of nanotechnology startups in promoting sustainability and economic growth
By focusing on nano-enabled water treatment and agriculture technologies, these startups help reduce water consumption and pollution, directly supporting Saudi Vision 2030’s environmental and sustainability goals.
In water treatment, nano-enabled technologies substantially reduce chemical usage, energy consumption, and waste generation. For instance, nano metal oxides act as powerful catalysts and adsorbents that degrade pollutants efficiently in wastewater, enabling cleaner water recycling with minimal environmental impact. Meanwhile, advanced nano-membranes extend membrane lifespans and performance in seawater desalination plants, curbing energy-intensive operations and lowering carbon emissions.
In agriculture, nano-enabled technologies increase overall agricultural productivity, support food security, and reduce import dependence, which benefits the economy.
Economic impacts arise from building a high-tech ecosystem where startups, research institutions, and government initiatives join hands to develop and commercialize nanotech solutions, ultimately accelerating job creation, enhancing local expertise, and boosting exports of advanced materials and sustainable technologies.
Nanotechnology in Saudi agriculture and water sectors faces several challenges despite its promising potential. Technologically, the development and deployment of nanosensors, nano-fertilizers, and nano-enabled water treatment solutions require deep interdisciplinary collaboration across synthetic biology, materials science, agronomy, and data engineering. On the side, fragmented regulations governing nanomaterial use and safety slow down the approval and scale-up of innovative solutions.
Finally, the future for nanotechnology startups in Saudi Arabia’s water and agriculture sectors is promising, although challenges remain. With continuous developments and supportive ecosystem growth, nanotechnology is expected to play a transformative role in securing water resources, enhancing agricultural productivity, and fostering sustainable economic diversification in line with Vision 2030.
