To reduce the carbon footprint of cement

Project overview

Cimbec Canada Inc. and Carboniq Inc. are developing a volcanic rock extraction project located in Dalhousie, New Brunswick. 

This rock, called pozzolan, has the chemical composition necessary to replace part of the clinker used in the production of cement. The manufacture of clinker is the source of significant greenhouse gas (GHG) emissions in this industry.

The aim of this pozzolan production is to provide the cement industry with a cementitious material with a very low carbon footprint, thus reducing the need for clinker. 

This project will thus contribute to the decarbonization of the cement industry, which happens to be one of the world's major emitters. 


Cement production accounts for approximately 8% of global CO2 emissions.

Sustainable solution

The use of pozzolan not only produces a better concrete, but also reduces the clinker-cement ratio and therefore also the final carbon footprint of the product.

Structures built in ancient times, using volcanic ash, are still present today

The Romans used a mixture of lime and pozzolan to build monuments, bridges, aqueducts and other structures.
