Water Management Companies in United Kingdom (UK)

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.
