Twin Brook served as administrative agent on a $76.795 million facility to support the merger of two Kinderhook Industries portfolio companies – Intergulf Corporation and STC Industrial – to form CIRCON Environmental

CIRCON Environmental will provide a complete range of liquids and solids waste management and product recovery services for the petroleum and petrochemical industries.

For three decades, Intergulf Corporation has been a Texas-based industrial liquids management business serving generators of both hazardous and non-hazardous liquid waste and co-product streams.

STC Industrial, headquartered in South Carolina, has a long history of successfully introducing proprietary waste extraction technology and creating innovative technologies to remove and transport liquid and solid residual waste from petroleum and petrochemical storage tanks.

“CIRCON Environmental brings together two industry leaders,” said Rob Michalik, a managing director at Kinderhook. “When we looked at the increase in capabilities and capacity coupled with the demands of a rapidly changing market, we realized the potential for growth a merger would create.”

Frank Iezzi, the current CEO of STC Industrial has been named chief executive officer of CIRCON Environmental. Brandon Velek, long-time CEO of Intergulf, assumes the role of board chairman.
