Worcester Polytechnic Institute (WPI) researchers introduced an enzymatic structural material (ESM), a next-generation building material designed to pull carbon dioxide from the air while it cures. Developed under the leadership of professor Nima Rahbar, ESM uses a specialized enzyme that converts CO2 into solid mineral particles, which are then bound together under mild conditions. The result is a structural material that hardens within hours instead of weeks, offering a low-energy alternative to conventional concrete.
The team reported the breakthrough in the journal Matter, detailing how ESM combines rapid curing with tunable strength and full recyclability. Its processing avoids the extreme heat required for cement production and enables fabrication into roof decks, wall panels, and modular components. Because the material can be repaired and reprocessed, it supports longer service life and reduced construction waste.
For consumers and cities, ESM signals a shift toward carbon-negative infrastructure that actively cleans the atmosphere as it’s built. Each cubic meter of the material sequesters several kilograms of CO2, positioning it as a distinct alternative to emissions-heavy concrete.
