CarbiCrete is a Montreal-based carbon removal technology company that is developing innovative, low-cost building solutions that contribute to the reduction of greenhouse gas emissions.

The company’s patented technology, first developed at McGill University, enables the production of cement-free, carbon-negative concrete. The process uses an industrial by-product – the slag from steel factories – to replace cement as a binding ingredient in precast concrete products. The process injects CO2 into the fresh concrete to provide strength, while permanently sequestering CO2 within the resulting products.

CarbiCrete licenses its technology to concrete makers and oversees the retrofit required to implement the process. Patio Drummond, a hardscape manufacturer in Drummondville, Quebec is currently producing and selling cement-free blocks using CarbiCrete technology. CarbiCrete’s corporate headquarters and R&D facility are located in Lachine, Quebec.
