Veolia Water Technologies is providing process technologies all along the battery value chain. Among other solutions our technologies are tackling challenging waste streams coming from the battery industry such as Sodium sulphate (Na2SO4) and turning them into valuable products which can be valorized and reused back in the process and closing the loop. Through our advanced Salt Valorization Technology (SVT), Veolia can convert waste Na2SO4 into valuable chemicals, lowering reagent costs while improving sustainability in battery material production.
