Overview

• Used ventilation filters from five schools within 1,500 meters of the plant contained higher concentrations of PFAS, PAHs and/or dioxins than new controls, indicating these compounds are present in nearby outdoor air.
• A dust sample taken from an apartment 700 meters from the facility showed high PFAS and dioxin levels, with dioxins exceeding concentrations reported in slag from a Dutch incinerator.
• The sampling was analyzed by Dutch consultancy ToxicoWatch as a non‑standardized pilot, and the NGOs stress that the results do not establish indoor exposure levels or definitively attribute emissions to the site.
• NGOs say the incinerator is a plausible source given that road traffic is not a direct PFAS emitter, and they call for continuous stack monitoring using PFAS methods and standardized airborne measurements.
• Syctom had not commented on the new report at publication; its president previously said regulatory thresholds are respected, and local officials note a new installation is slated to start operations in December 2025.
