Water scarcity is a pressing global issue, with predictions indicating that by 2030, half of the world’s population will reside in water-stressed regions. Access to clean water, sanitation, and hygiene is critical not only for human health but also for the stability and prosperity of societies. Despite the challenges, young innovators are stepping up to develop solutions to address this crisis. Their ideas were recently showcased at the international conference on Water for Sustainable Development held in Dushanbe, Tajikistan.
As urban populations swell, millions are grappling with water scarcity and contamination, a problem projected to affect over 2.3bn people by 2050. Simultaneously, wastewater and untreated sewage contribute significantly to ocean pollution, creating "dead zones" and threatening public health.
Cycleau, a compact water treatment system, offers a promising solution by transforming greywater—wastewater from sinks, showers, and laundry—into potable water. This innovative system, designed by LÆRO Design Studio’s founder and CEO Noemi Florea, employs four stages of filtration, disinfection, and heat recovery to remove over 200 contaminants from greywater. The system can be installed in urban housing projects, off-grid camps, and other settings, capturing up to 80% of greywater for reuse.
"My work on Cycleau has shown how I was able to transform my personal experience facing water scarcity and contamination into developing an alternative solution for water treatment that breaks regulatory and cultural norms regarding water reuse,” Florea explained.
Cycleau can reduce a building's water footprint by up to 80% and the energy footprint of water utilities by 40%. Cycleau's versatile design has attracted interest for use in various applications, including RVs, hydroponics, and disaster relief. Florea envisions the system inspiring a new approach to water resource management by creating clean water access through reuse strategies.
In Central Asia, where water scarcity has severe impacts, HurRain NanoTech has turned to nature for inspiration. By studying desert beetles and cacti, the team developed a technology that harvests high-quality drinking water from the air, even in low-humidity conditions.
After five years of research at Tsinghua University, the team created an adsorbent functional nanocomposite material capable of rapidly absorbing moisture in arid environments. This innovation has the potential to bring clean water to regions where access is limited.
“We have visited many water-scarce areas in China, including mountainous regions where people only have water during the rainy season,” said Tina Tan, HurRain NanoTech's marketing director. "With our atmospheric water generation technology, we bring hope to local communities. The local government has also started to invest in water management after seeing the potential of our project."
The efforts of these young innovators highlight the importance of creative solutions in addressing global challenges. As they continue to develop and implement their ideas, they bring hope to millions facing the devastating impacts of water scarcity.
