M MILENARES was initially created to produce and supply natural aggregates for the industrial sector. This area of activity has developed extensively and currently has a coverage of supply of aggregates for the entire Center and North region.

However, strategically, the Administration developed a new business area, related to waste management from the ceramic industry and the construction and demolition sector. These materials are sorted and treated, enabling the production of a new recycled aggregate. This is the production of recycled Tout-venant with CE marking, which is being reincorporated into the construction sector.
