Zero Harm Commitment

Zero Harm is our culture's foundation—our commitment to ensure the care and protection of our employees, our communities, and the environment comes first in all decisions. We believe that operating with Zero Harm as our first priority, always, is inherent to success in other areas such as productivity and profits—and we have the results to prove it.

Koppers is Built on Circularity

In the early 1900s, the Koppers brand was founded on the concept of circularity, when German engineer Heinrich Koppers created a new kind of coke oven furnace that would recover key by-products and use them to create new products rather than release them into the atmosphere. More than a hundred years later, the circular economy continues to drive our company today.

At least 75 percent of our products by revenue are made from recycled, reused, or renewable materials. We reuse waste and scrap materials from other industries as key production inputs, and use renewable resources for another significant portion of our raw material requirements—placing our company at the center of the circular resource economy.
