Core Viewpoint - The Ministry of Ecology and Environment has released the "Hazardous Waste Exclusion Management List (2026 Edition)", which clarifies that the solid waste listed does not fall under hazardous waste classification. The new list will take effect immediately, replacing the 2021 version [1]. Group 1: Key Changes in the Exclusion List - The 2026 edition includes 11 categories of solid waste, with five new additions compared to the 2021 version. These include waste aluminum oxide from hydrogen peroxide production, wastewater treatment sludge from water-based architectural wall paint production, filter residue and wastewater treatment sludge from acrylic emulsion production, cobalt slag from cobalt refining, and discarded ion exchange resins [1]. Group 2: Purpose and Impact - The "Hazardous Waste Exclusion Management List" is part of the hazardous waste identification system. Solid waste included in the exclusion list is not classified as hazardous waste. This initiative aims to clarify the attributes of solid waste that are currently ambiguous and of public concern, thereby standardizing management practices, enhancing environmental management levels, and reducing solid waste management costs for enterprises [1].
