Fonderie B. Marcoux: A Focus on Eco-Responsibility

Today, as recycling is fundamental and environmental concerns are essential, Fonderie B. Marcoux is mindful of the environment and wishes to contribute to global efforts. That is why we use recycled materials as often as possible.

Cast iron: 80% of our castings are made from recycled materials (including car break discs).

Aluminum and bronze: The material is bought in the shape of ingots made from different recycled parts.

Sand: The sand is up to 95% recycled. Since only water and clay are added to the sand, the sand has no harmful effect on the environment.
