The Zaldibar crisis diverted waste accumulated with little control in the Eitzaga district to several CAV landfill sites. In the case of Vitoria-Gasteiz, the municipality approved in February a total of 23,000 tonnes of additives. Since then, it has received nearly 2,000 petitions and, according to Naiz, has received another 15,000 petitions. Opposition groups, such as the PP, have expressed disagreement in stating that they have received sufficient amounts in two months and that this limit of EUR 23,000 will easily pass in two years.

Councilor for Environmental Management and Planning of the PNV, César Fernández de Landa, has pointed out that if companies continue to demand, they will have to start controlling waste entering the landfill.

The City Council of Vitoria-Gasteiz approved, within a few days of the Zaldibar accident, a 23% increase in the amount of waste that Gardelegui would accept, according to the request of the Environment Department of the Basque Government. It set a period of twelve months to withdraw the 23,000 tonnes of these additives, but left open the door to the extension of that period.

However, there is still a lot of waste to be disposed of in all landfills. In fact, according to the Basque Government, between Zaldibar and Mutiloa, 850,000 tonnes were collected per year, which represents one third of the total industrial waste generated in the CAPV, of which 500,000 were collected only at Zaldibar.

The Basque Government estimated that, distributed in other landfills, some 250,000 tonnes of waste still had to be separated. In this regard, the Basque Government signed that the dumping of waste from other autonomous communities of the Spanish State in the CAPV required the authorization of the Department of Environment and Territorial Planning.
