Kohler keeps porcelain waste out of landfills


Kohler partners with businesses, municipalities to keep porcelain waste out of landfills for past 15 years.

This vitreous china (porcelain) cull comes from toilets and lavatories that have not passed inspection for sale to customers. If a defect is found after glazing, the standard protocol has been to send the porcelain waste to the landfill, but, the company has been able to avoid depositing cull into landfills for the past 15 years at its pottery operations in Kohler, Wisconsin.

By partnering with Wausau Tile, Kafka Granite, the Village of Kohler, and other Kohler business ventures, Kohler has provided cull to be used as aggregate in road pavers and drainage projects, epoxy overlay, blended in concrete and tile products, and used in the golf courses drainage systems, among other projects.

“We are extremely proud that we have been able to find alternative uses for porcelain cull that support our commitment to sustainable business practices,” says Jim Lewis, vice president of Kohler brand and channel marketing. “To know that you are walking on a street paved with discarded toilets, or sit on a concrete patio bench constructed from broken sinks, it really makes you understand and appreciate that sustainability is only achievable when we can work together.”

Across the country, similar reuse programs are being tested and implemented in a variety of Kohler manufacturing locations where cull is being used in landfill roads, drainage structures and plant parking lots.

“Utilizing Kohler’s porcelain cull has proven to be a cost-effective endeavor for the Village of Kohler and its residents,” says Bruce Neerhof, Public Works and Zoning Superintendent for the Village of Kohler.

Wausau Tile’s EcoPremier line, including patio tables, utilizes recycled porcelain cull

“So many times customers perceive green products as being more expensive,” says Rodney Dombrowski, vice president of operations at Wausau Tile. “But by recycling Kohler porcelain cull into our concrete and tile products, we are able to offer our EcoPremier line at basically the same price as our standard lines, making for an affordable green option in any building environment.”

An additional benefit for builders is that Wausau Tile products which utilize recycled Kohler cull will increase LEED points potential for projects through the material reuse and recovery resources section of LEED, the United States Green Building Council’s internationally recognized green building certification system.
