As every year, on April 11 we celebrate the traditional Day of Trees and Aggregates, an initiative of aggregate manufacturing companies. A day organized by ANEFA and associations such as the FdA and the Gremi d'Árids de Catalunya, of which PROMSA is a member.
The objective of the day is to bring the youngest ones, in a didactic way, to our sector and show them the importance of raw materials in their daily lives. In addition, to transmit to them how these matters can be extracted respecting the environment and the biodiversity of the territory.
