Water Management Companies in Europe

Watercycle Technologies Ltd is a UK-based deep tech company focused on developing sustainable, high-yield, low-cost, mineral extraction and water treatment systems. Able to treat highly concentrated water, its core technology is an end-to-end solution spanning mineral extraction, concentration and crystallisation. This is initially being utilised in lithium production from sub surface water and brines, lithium-ion spent battery recycling, which is particularly relevant with regards to the current global transition towards a Circular Economy, and advanced desalination systems. The Company is committed to reducing the environmental cost of mineral extraction and increasing the availability of clean water. With a strong ethics-based business model, Watercycle is positioned to deliver profitable commercial solutions centred on sustainability, environmental protection, and remediation. Its experienced R&D team, led by Dr Seb Leaper and Dr Ahmed Abdelkarim, is targeting industries including mining, desalination, agriculture, textiles, and food and beverage. Importantly, the modular technology delivers dramatic reductions in costs and carbon emissions with the main by-product being fresh potable water.

CrayoNano is a global semiconductor component supplier enabling a sustainable and healthier life for everyone through market-influencing photonic device technologies. Our CrayoLED™ H-Series (CLH-N3S) is an ultraviolet-C light emitting diode (UV-C LED) semiconductor packaged component. CrayoLED’s quality-driven design meets the high standards for reliability and performance in the fast-growing industrial and commercial disinfection and sanitization market. UV-C radiation deactivates various bacteria, viruses, and illness-inducing pathogens. Until today, sanitization and disinfection have been dominated by mercury lamps and chemical cleaning. CrayoLED™ enables automated, low-maintenance solutions using fewer chemicals. The CrayoLED™ is optimized for disinfection at a typical peak wavelength of 275nm. Its small package footprint (3.5mm x 3.5mm) and high power performance (typical 80mW optical power at 350mA) easily integrates into systems for residential, commercial, and industrial segments, enabling system miniaturization and longer lasting solutions. CrayoLED™ H-series (CLH-N3S) is available in both sample quantities and in stock for volume production.
