Kinderhook merges portfolio companies Circon, Chemtron and KilnDirect

Frank Iezzi will serve as CEO of the combined ESG-focused environmental solutions platform.

Kinderhook Industries has merged three sustainable waste management portfolio companies: Circon Environmental, Chemtron Corporation and KilnDirect. The combined entity will operate under the Circon brand name. Financing for the transaction was provided by Twin Brook Capital.


New York, NY – Kinderhook Industries, LLC (“Kinderhook”) has announced the merger of Circon Environmental (“Circon”), Chemtron Corporation (“Chemtron”) and KilnDirect Inc. (“KilnDirect”). Each company was an existing portfolio company of Kinderhook and will be rebranded under the Circon Environmental name.

The merger will create a leading pure-play provider of sustainable waste management solutions. Circon, Chemtron, and KilnDirect each are dedicated to the engineering and processing of non-hazardous and hazardous waste streams to create high-quality and valuable fuel replacements to traditional natural gas and coal. The vertically-integrated platform will have the scale and capabilities to provide extensive, end-to-end environmental solutions on a national level for waste generators across all end markets. Circon will be able to solve the most complex waste challenges, while continuing its commitment to a sustainable and circular economy.

“We are excited to combine three successful companies to create an ESG focused environmental solutions platform. We believe the lack of a pure-play sustainability-focused provider of scale in the market creates an unique opportunity for the combined company and we look forward to building this consolidated platform with our management team,” said Rob Michalik, Managing Director at Kinderhook.

Frank Iezzi, who will serve as CEO of the combined platform added, “We are excited to welcome in Chemtron and KilnDirect into our growing family of companies. Through the addition of the Chemtron and KilnDirect teams, Circon’s expertise will be even stronger as we expand the products and services we offer with a focus on delivering an ever-growing level of sustainable environmental solutions to our customers.”
