According to EiTB, the company Verter Recycling 2002, S.L. will use two depths located on the slopes of Mount Motia, occupying an area of 68,555 square metres, next to the landfill where Zaldibar collapsed. It will have a storage capacity of 804,000 cubic meters, it will cost 13.4 million euros and, in the words of EiTB, "guarantee the continuity of the search for the two buried workers and the stabilization of the terrain". The bodies of Alberto Sololuze and Joaquín Beltrán, who were captured by the Zaldibar disaster under the rubbish mountain, have not yet appeared.

The Environment Department has taken into account the "suitability" of the site, its "scarce" impact on the environment and the increased reception capacity for landslide waste that will continue to be excavated and mobilised in the medium term. The planned period for the construction of this extension of the Zaldibar landfill is 20 months, from the start of the works until their closure, although it is planned to be phased in.
