NEREUS provides innovative and sustainable recycling systems for effluents like digestate, wastewater...

NEREUS designs, develops and builds industrial water extraction units from complex effluents like manure, digestate or wastewater for industries and communities. Industrial development, intensive farming and growing urbanization contribute to increased energy and clean water needs. According to the United Nations, in 2025, the average quantity of available fresh water per resident and per year is forecast to fall from 6 600 to 4 800m3. Experts estimate that there will be 5 times more people on Earth suffering from severe water scarcity than today, which will represents 35% of the total population. Because water and energy are often linked, NEREUS focuses on the recovery and recycling of these two essential goods. Our missions: > Recover the maximum amount of liquid wastes and remove their pollution > Develop technologies and processes helping our customers to integrate sustainable development by connecting ecology to economy > Respect the nexus water-energy in all our processes Nereus, nicknamed the old man of sea, takes its name from one of the oldest Greek divinity. He is the son of Pontus, god of sea, and Gaïa, mother of Earth. This name is the core of our mission: recover water in order to protect the Earth.
