Today a meeting of the Technical Committee of the Gremi d’Àrids of Catalonia was held at Creaf. El Gremi is an association that brings together Catalan companies that dedicate their economic activity to the extraction and treatment of aggregates. Part of the activities is the recovery of disused quarries with their specific challenges of little or no soil and great dryness. From the Creaf a plantation with Cocoons will be organized in celebration of the day of trees and aggregates.
