Project Innovation + Advantages:

MIT will develop an electrochemical approach to extracting and purifying valuable elements from municipal solid waste incinerator ash, powered solely by electricity from the waste-to-energy plant. The approach is capable of recovering at least 95% of critical materials and at least 90% of other metals while avoiding producing additional hazardous emissions. MIT’s approach uses electrochemical reactions to extract elements that include rare-earth elements and valuable base and noble metals. The proposed technology can upcycle major elements in fly and bottom ash, including calcium and silicon, to value-added products such as lime and silicates for use in construction applications.
