DALHOUSIE POZZOLAN PROJECT
To reduce the carbon footprint of cement
Project overview
EcoRock Dalhousie Inc. is 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. Clinker production is the source of significant greenhouse gas (GHG) emissions in this industry.
The aim of this pozzolan production would be to provide the cement industry with a cementitious material that has a very low carbon footprint, thus reducing the need for clinker.
This project would thus contribute to the decarbonization of the cement industry, which happens to be one of the world's major emitters.
FIGHT AGAINST CLIMATE CHANGE
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 standing today
The Romans used a mixture of lime and pozzolan to build monuments, bridges, aqueducts and other structures.
Location
The pozzolan deposit has been identified in Dalhousie, at the northern tip of New Brunswick, on the shores of Chaleur Bay and at the mouth of the Restigouche River (Canada).
Dalhousie Pozzolan project would benefit from the presence of existing major infrastructure, including a port opening onto the Atlantic Ocean that can accommodate 30,000-ton ships year-round, a railway, a former industrial site, and finally the quarry itself which has been in operation for several decades to meet certain needs for regional aggregate.
