Since 2006, Orège has worked in the area of innovation, design and industrialisation of treatment solutions for municipal and industrial sludge and complex effluents.

Orège received a prize at the Global Water Intelligence Awards in the category of “Breakthrough Technology of the Year” for its SLG (Solid Liquid Gas) technology, which is revolutionising the treatment and conditioning of sludge. SLG is a highly innovative technology whose spectacular results significantly reduce the volume of sludge produced, eliminate any odours and improve its quality, thereby enhancing its recycling potential.
Orège has begun to develop successfully in the United States and signed its first contract in 2016 with one of the three leading American engineering companies working in the area of the validation and adoption of innovative technologies in the water sector.
