Columbus Issues Demolition Permit for Concrete Silo at Calgon Carbon Facility
The city approved razing a 5,100-square-foot structure to grade as site preparation for an ongoing $90 million drinking water treatment expansion.
The City of Columbus Department of Building and Zoning Services on Tuesday, Oct. 6, issued a commercial demolition permit to raze an industrial silo at Calgon Carbon Corporation's Northeast Columbus facility.
The permit, designated DEMO2640270, authorizes the demolition of a 5,100-square-foot concrete silo to grade at the 835 N. Cassady Ave. property.
The demolition provides site clearance for an ongoing facility upgrade. On June 29, 2026, Calgon Carbon Corporation, a wholly owned subsidiary of Japan-based Kuraray Co., Ltd., announced plans to invest nearly $90 million to expand and modernize its existing Columbus manufacturing facility.
According to company officials, the facility reactivation project will add capacity to reactivate carbon used in municipal drinking water systems, helping utilities meet growing demand for treatment solutions that address PFAS, or perfluoroalkyl and polyfluoroalkyl substances commonly called "forever chemicals."
The facility takes used carbon from water treatment systems, cleans and restores it so it can be used again, reducing landfill waste for municipal water utilities. Calgon Carbon said the expansion will create 17 new jobs, building upon the 42 existing positions at the Cassady Avenue plant.
The issuance of the demolition permit authorizes contractors to begin razing the structure to ground level. Before site preparation concludes, the project requires the physical teardown of the concrete silo, utility disconnects, and final city building inspections to close the demolition permit. Subsequent commercial building permits and regulatory approvals will be required before Calgon Carbon can construct new facility infrastructure on the cleared site.
