Khalifa University and Green Waste Solutions Trading DMCC win top international honours

Two prominent Emirati institutions have been recognised at the Mohammed bin Rashid Al Maktoum Global Water Award, in a milestone that underscores the UAE's leadership in sustainability and innovation.
Khalifa University won the Innovative Research & Development Award (National Institutions category) for its Biomimetic Freshwater Generator for Solar Desalination without Brine Discharge project.
Green Waste Solutions Trading DMCC, based in the Dubai Multi Commodities Centre (DMCC), won the Innovative Projects Award (Large Projects category) for its LANDCO Tech initiative, which transforms organic waste and wastewater into clean drinking water, renewable energy and bio-fertilisers.
The award ceremony saw His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai, honour the two institutions as part of the 12 winners from eight countries across the award's four categories.
With total prizes of $1 million, the Mohammed bin Rashid Al Maktoum Global Water Award is supervised by the UAE Water Aid Foundation (Suqia UAE), under the umbrella of the Mohammed bin Rashid Al Maktoum Global Initiatives. It aims to find sustainable and innovative solutions to address water scarcity worldwide.
Khalifa University's winning device mimics the natural evaporation process of mangrove trees to produce freshwater from seawater and passively collect salt as a byproduct, eliminating the need for brine discharge. It employs sustainable solar thermal distillation technology and uses the principle of interfacial solar steam generation, where solar energy absorption and vapour production occur at the water surface, minimising heat losses and improving energy efficiency.
Under real-world conditions, the device produces 2.2 litres of freshwater per square metre daily from seawater, which is sufficient to meet individual drinking needs. It can also be scaled up to meet higher water demands. The device has been tested using synthetic seawater and Abu Dhabi seawater, and it meets WHO standards. A PCT patent application for the invention has been filed in the US and ADNOC has expressed interest in adopting the technology to treat produced water from oil reservoirs.
'The global water crisis may be just a slogan in some parts of the world but, for us, it is a very real and urgent challenge that directly affects the future of our next generations. Addressing this crisis is essential for achieving sustainable development, not only in our region but globally. The key lies in innovation. With our technology, people can survive in remote areas without access to traditional infrastructure. This award is truly significant and plays a critical role in supporting efforts across this region. By investing in such a vital field, we can drive meaningful change. The UAE is uniquely positioned to lead and support global solutions,' said Dr TieJun Zhang, professor of mechanical engineering and Associate Dean of the College of Engineering and Physical Sciences at Khalifa University.
Dr Faisal Al Marzooqi, associate professor of chemical engineering and Deputy Director of the Centre of Membrane and Advanced Water Technology (CMAT) at Khalifa University, said water is a limited and precious resource that has to be used wisely – both here in the UAE and around the world.
'Our innovation harnesses solar energy to desalinate water while producing useful salts, enabling sustainable water production in remote areas. The Mohammed bin Rashid Al Maktoum Global Water Award is a powerful incentive for us to continue our efforts, push the boundaries of our technology and expand its impact both locally and globally,' said Dr Al Marzooqi.
The award-winning LANDCO Combo system, developed by Green Waste Solutions Trading DMCC, is a fully integrated solution that converts organic waste and wastewater into clean drinking water, renewable energy and liquid bio-fertilisers. Housed in 40-foot COMBO containers and equipped with solar panels, the modular system includes an anaerobic digester, ultrafiltration and reverse-osmosis units, a heat exchanger and a 15kW electrical generator. Wastewater is treated to extract potable water that meets WHO standards (pH: 6.17), while the remaining digestate is repurposed as fertiliser for on-site crop cultivation.
The system also produces biogas for energy use and integrates blockchain and AI tools for remote monitoring and operational optimisation. The solution has been deployed in Egypt and Botswana, producing up to 100,000 litres of water daily in El Gouna and serving 20,000 people in Maun. It is designed for easy deployment, maintenance and scalability, with a 15-year lifecycle and replaceable components. The system is particularly beneficial in refugee camps and underserved communities, where it supports local job creation, reduces pollution, and improves living conditions.
'The key to solving the water crisis lies in encouraging people to take responsibility for how they interact with natural resources. Ultimately, it is a matter of education. We believe that the platform provided by this award plays a vital role in raising awareness that innovative technologies already exist to improve lives, especially in terms of environmental impact. I'm deeply grateful to Sheikh Mohammed bin Rashid Al Maktoum, Vice- President and Prime Minister of the UAE and Ruler of Dubai, for his commitment to improving life on this planet for us, and for our children and grandchildren. Our team continues to work on advancing this technology, making it more affordable and scalable so it can be implemented wherever it's most needed around the world,' said Andre Holzer, CEO and founder of Green Waste Solutions Trading DMCC.
The Mohammed bin Rashid Al Maktoum Global Water Award continues to support the UAE's efforts to address the challenges of water scarcity. The award aims to find sustainable solutions that ensure the availability of freshwater for impoverished communities around the world and other vulnerable groups. This supports a brighter future for generations to come. The fourth cycle of the award saw strong international participation, attracting submissions from 46 countries.

Telegram's Pavel Durov to Divide Wealth Among His 100+ Kids

In true plot-twist fashion, Pavel Durov—founder of encrypted messaging giant Telegram —is planning to share his multi-billion-dollar fortune with over 100 children across the globe. Yes, 100+, and no, this isn't a sci-fi storyline. Speaking to French magazine Le Point, the 40-year-old tech mogul confirmed he has fathered six official children, along with dozens more through sperm donations in at least 12 countries. "I don't want them to tear each other apart after my death," he told the publication. His goal? Equal rights and zero posthumous drama. But don't expect these heirs to be cashing in anytime soon. Durov revealed that none of the kids—official or donor-conceived—will have access to their inheritance for another 30 years. 'I want them to live like normal people... to build themselves up alone... not to be dependent on a bank account,' he said, explaining that character matters more than cash. Based in Dubai, Durov recently made his will, citing the risks that come with his mission to defend freedom and privacy in an increasingly monitored world. 'Defending freedoms earns you many enemies, including within powerful states,' he noted. Telegram, launched in 2013, has become one of the world's most-used messaging platforms, clocking over a billion users monthly. But its unfiltered nature hasn't gone unnoticed by law enforcement. French authorities arrested Durov last year for allegedly failing to combat criminal activity on Telegram—accusations he firmly rejects. 'Just because criminals use our messaging service among many others doesn't make those who run it criminals,' he said. From creating an app used by millions to now creating… a massive inheritance plan for over 100 kids, Durov is definitely in a league of his own.

Historic Sharjah site is candidate for Unesco World Heritage status

A site in Sharjah where evidence of human habitation dating back more than 210,000 years has been found is a candidate for Unesco World Heritage status. Faya, an ancient archaeological site of huge significance in the Arabian Peninsula, is among 30 sites being considered by the UN's cultural body. Unesco's World Heritage committee will now make a decision at its 47th session to be held from July 7 to 16 in Paris. The Sharjah site is what is known as a palaeolandscape, providing insights into how early humans lived, migrated, and adapted to environments. Sheikha Bodour Al Qasimi is the official ambassador of the emirate's Unesco World Heritage nomination file. 'Faya offers one of the oldest and most complete records of early human presence in Arabia, dating back over 210,000 years - a living archive that deepens our understanding of who we are, where we came from, and how we have learnt to survive,' said Sheika Bodour, in remarks carried by state news agency Wam last month. 'The Faya palaeolandscape's nomination for Unesco World Heritage status highlights the importance of preserving these ancient sites, not only for their historical value but for their potential to educate future generations. As ambassador, I see this nomination as an opportunity to elevate Faya as a shared inheritance for all people around the world." Research pays off The Faya Range, a chain of limestone outcrops known in Arabic as jebels, can be considered a natural barrier between the Rub Al Khali desert to its west and the Dhaid-Madam plain to its east. The area is rich in resources such as flint and freshwater springs, which made human settlements there. There is evidence of human tools, life and burials. Scientists say the environment and people's way of living changed over thousands of years in the area. 'Over 30 years of meticulous research and collaboration led by our national mission and experts with international experts have revealed 18 distinct archaeological layers from the Stone Age, bringing to light an intricate history of human evolution, adaptation and survival right here in Sharjah,' said Eisa Yousif, director of the Sharjah Archaeology Authority, in remarks also carried by Wam. 'As we advance Faya's Unesco World Heritage nomination, it is important to emphasise that our collaborative efforts have made this a global project; one that connects the past with the present more strongly, adding to the rich global corpus of archaeological discoveries. This property, therefore, holds immense value for the world - not just Sharjah and the UAE," he added. Faya was added to Unesco's tentative list in 2023. The UAE has developed a comprehensive management plan for the Faya Palaeolandscape, which will guide its conservation, research, and visitor engagement from 2024 to 2030, Wam said. This plan aligns with Unesco's World Heritage standards, ensuring that the site is preserved while also allowing for continued exploration and education. The UAE has currently one site on the heritage list. The cultural sites of Al Ain (Hafit, Hili, Bidaa Bint Saud and Oases Areas) were collectively added in 2011. Unesco's meeting, meanwhile, will also see it examine the extension of two sites already on the list and will review of the state of conservation of 248 sites already inscribed. To date, it has inscribed 1,223 cultural and natural sites in 168 countries on the World Heritage list.
