Oneida County staff say PFAS tests reclassify fiber cake as solid waste; 8,000 tons on site

Mar 20, 2025

Solid Waste Director Lisa Bauknecht told the county committee that PFAS testing associated with a 2024 permit renewal led the DNR to classify fiber cake on site as solid waste. The department will stop accepting more material, post a corporation-counsel-reviewed letter to purchasers, and explore disposal options for roughly 8,000 tons.

The full story

Solid Waste Director Lisa Bauknecht informed the Oneida County Public Works & Solid Waste Committee on March 20 that recent PFAS testing has changed how the county must treat fiber cake used for composting. Bauknecht said the material was tested for PFAS as part of the 2024 permit renewal and that the Department of Natural Resources now considers the county’s existing stock of fiber cake — roughly 8,000 tons of raw and mixed material — to be solid waste.
