Rejoul Inc. extracts critical metals from E-waste including Battery waste using it's proprietary Bio-tech process. Unlike traditional chemical based process, we use waster water sludge instead of expensive and toxic chemicals to extract the critical metals (Li, Ni, Co, Mn) from the battery black mass resulting into zero carbon and toxic emissions while significantly reducing the costs. These metals are extracted in sulfide form and are protein coated with superior semi-conducting properties allowing it to be reused in the Battery, Solar Cell and Semi-Conductor manufacturing, ensuring a circular economy.
