About DMT Environmental Technology

Our story

Building the foundation

Originally DMT Environmental Technology was founded as Dirkse Milieu Technologie in 1987, after the founder Rob Dirkse. Dirkse Milieu Technologie means Dirske Environmental Technology and due to the many international activities of the company soon became DMT Environmental Technology. Rob Dirkse retired in 2001 and was succeeded by his son Erwin Dirkse who had been managing director from 1999 until 2021. Technologies for biogas upgrading and gas desulphurisation gained a reputation in the Chinese and South American market and in 2014 95% of all the companies activities were international.

DMT International

DMT Environmental Technology is part of DMT International, a global organisation with over 100 employees agents and partners spread throughout Europe, North America and Asia. DMT International also holds DMT Clear Gas Solutions, in operation since 2015 and established by Robert Lems, former R&D manager at DMT Environmental Technology. DMT’s award-winning portfolio proofs that DMT is an undeniable player in the field of biogas upgrading and gas desulphurisation.

To continue the development path and further stimulate the organisation’s growth, Broadview Energy Solutions BV acquired DMT. “The support of Broadview Energy Solutions will allow us to successfully realize DMT’s long-term plans in the biogas upgrading market, says Theo Zuijdwijk CEO of DMT.
