Called by the Anti-Incineration Movement, dozens of people gathered on Saturday, May 23rd, in front of the headquarters of the Gipuzkoa Provincial Council, in Donostia's Gipuzkoa Square. There, they formed a long human chain with various messages to denounce the incinerator's operation. These messages served as a warning, highlighting that the incinerator is one of the largest CO2 emitters in Gipuzkoa, that it does not generate energy, and that it spreads dioxins, heavy metals, and PFAS pollutants. They also denounced that it wastes public money and waste resources, and that burning waste is a business for large corporations.

Protesters demanded the closure of the incinerator, stating it is "polluting, expensive, unfair, and useless," and emphasizing the need to protect health. Organizers also displayed a wide collection of posters from past mobilizations. The aim of the demonstration was for the leaders of the Gipuzkoa Provincial Council and the Donostia City Council to hear their demands, and for the protest to be visible in Donostia.

They also recalled warnings from international experts, noting that the poisons, dioxins, furans, heavy metals, and PFAS released by the incinerator are accumulating year after year. According to data shown by researchers from ToxicoWatch, the plants, animals, and people living in the environment contaminated by the incinerator are the ultimate sink, and they are the ones suffering the damages of waste incineration.

In this context, organizers urged the authorities of Donostia and Gipuzkoa to act responsibly and, taking into account expert warnings, to organize proper waste management, once again demanding the closure of the "criminal incinerator of Zubieta."

According to the statement, Donostia recycles the least among Gipuzkoa's municipalities, thus feeding the Zubieta incinerator the most. The authorities of the Donostia City Council were urged to manage waste responsibly and to promote waste management by minimizing its generation.
