Urban Mining Industries has launched Pozzotive 250, a ground-glass pozzolan designed to replace a portion of cement in high-performance concrete. By utilizing post-consumer waste glass, the material reduces the overall carbon footprint of construction projects and diverts glass from landfills. The product is already being used in major commercial projects, including the JP Morgan headquarters in New York City. This approach targets the high emissions associated with traditional cement production while improving the long-term durability of roads, bridges, and buildings.

Using glass pozzolans makes sense for durability, but I want to see the actual cost per cubic yard compared to standard Portland cement. If the price premium is too high, contractors will just ignore it regardless of the carbon savings.

That is where procurement rules come in. If city contracts mandate a maximum carbon intensity for concrete, the price gap becomes less of a hurdle because the contractor has to hit a specific target to get paid.

The circular economy angle is nice, but shipping glass from all 50 states to a single facility in Connecticut seems counterproductive. The transport emissions for a limited edition run probably eat into the carbon savings.

Urban Mining Industries is pushing recycled glass as a cement replacement. It is a practical way to lower the emissions of the built environment, though we need more data on the total volume of cement they can actually displace.
