This report by RMI examines the potential for integrating carbon dioxide removal (CDR) technologies into municipal and industrial wastewater treatment and biosolids management. It identifies two primary intervention categories: alkalinity management to store carbon as bicarbonates in water, and the processing of biosolids through methods like biochar production, biomass burial, and incineration with carbon capture. The report highlights synergies such as the safe disposal of hazardous contaminants like PFAS and the use of existing pumping infrastructure to reduce capital and energy costs.
