Project Term:
06/24/2022 - 06/23/2025

Technology Description:

Cornell University will develop a scalable technology to co-utilize waste construction and demolition (C&D) residues and CO2 to produce sustainable construction materials via several closely integrated innovations in cement production. The team will: (1) replace conventional fossil-driven high temperature processes with electrochemical low-temperature modular processes, (2) capture and reuse CO2 emissions to produce calcium carbonate (CaCO3) by using the inorganic components of C&D materials, (3) harness hydrogen and CaCO3 from organic constituents of C&D materials, and (4) manufacture reagents such as citrate and glycinate, useful for capturing CO2 and dissolving waste construction materials, by electromicrobially fixing CO2 and nitrogen.

Potential Impact:

If successful, this project will be a competitive and transformative technology that replaces thermally intensive processes for producing construction materials with integrated electrochemical and chemical approaches that co-utilize CO2 emissions and construction and demolition materials. It will:


Pave the way for distributed, on-demand synthesis of sustainable construction materials.


Replace fossil fuel-driven thermally intensive processes for cement production with renewable energy-driven, low-temperature electrochemical technologies with inherent reuse of construction and demolition materials and CO2.


Recover > 90% calcium from construction and C&D materials to produce CaCO3 for cementitious materials.
