The subject is very old, but last Tuesday the Minister for Rural Development and the Environment of the Government of Navarra, José María Aierdi, reported in the Parliament of Navarra. In it he explained that the company EcoάSansoain of Artajona received in the last two years 5,000 tonnes of leachate from the Zubieta incinerator between 2022 and 2023.

The Government of Navarra has therefore provisionally closed the composting plant in Artajona until the circumstances are clarified and the responsibilities are fulfilled. As Aierdi explained, this plant receives organic waste for composting, so in no case can it collect liquid waste.

In the valleys of Aierdi, following the studies carried out by the inspectors, it was found that the leachate from the incinerator of Zubieta was wrongly declared to Navarra and was illegally collected by the company Ecoved. At Wednesday's hearing, José Ignacio Asensio replied that this was not true, that Zubieta's waste certifications are provided by the Basque Government, which in this case has also been so, that the leachate sent to Navarra has had a biological treatment and has not gone through the incinerator.

According to Aierdi, however, the Government of Navarra has not given any qualification to the leachate from Gipuzkoa, but has stated that the Artajona plant cannot receive leachate, whether toxic or not, “nor could it receive the drinking water Insalus”. He explained that the contacts between the Provincial Council of Gipuzkoa and the technicians of the Government of Navarra mean that no leaching of this kind has been sent to Navarra since 18 December.
