Volbas has managed an inert construction and demolition waste dump located in Enekuri - Erandio. After more than thirteen years of filling, and in accordance with the new environmental policies promoted by the institutions, the installation of a Treatment and Recovery Plant for this type of waste began.

Currently, as an authorized manager by the Department of Environment and Spatial Planning of the Basque Government, it carries out the global recycling process of inert construction and demolition waste at its Enekuri facilities, from the reception and weighing of trucks, passing by the manual and mechanical separation of the admitted materials until obtaining recycled aggregates of high quality and different granulometries.
