Primary Aggregates

First-use or primary aggregates are normally from a quarry and have not been used before. This covers all sands, gravels, crushed stones, and certain slags. The material is in its primary state, just as it was when naturally in the ground. MCM source locally to the customer site, reducing carbon footprint, emissions and contributing to a healthier environment.

This differs from Recycled or Secondary Aggregates which have been used, recovered, cleaned and sold as an economic and environmentally friendly alternative.
