What Eisenmann Environmental Technology does

Eisenmann Environmental Technology GmbH is a German industrial plant engineering company headquartered in Holzgerlingen, Baden-Württemberg, that designs and builds turnkey environmental technology systems for industrial customers. The company's portfolio covers three pillars: Air (regenerative thermal oxidation [RTO], thermal oxidation, and adsorption wheel systems for VOC and toxic exhaust air); Water (Fentox Fenton oxidation for toxic wastewater, process water generation, and filtration/membrane systems); and Residual Materials (rotary kilns, Turaktor high-turbulence combustion chambers, conventional and chemical munitions disposal systems, and the patented NaRePAK process for recycling PAH-containing road construction materials). Its proprietary technologies — including Fentox, Turaktor, NaRePAK, BlueMax burner, and a patented rotary valve for RTO systems — are protected by patents and have earned recognition such as the Baden-Württemberg Environmental Prize, with documented performance metrics including RTO thermal efficiencies up to 99% and COD/AOX reductions up to 90% via Fentox.

The company sells primarily to large European and Chinese enterprise customers across chemicals (Bayer, DSM, Dow, CP Chem, Koehler, Lunan Chemicals), pharmaceuticals (Roche), automotive (BMW), metals (Novelis, Speira), defense (KNDS, Rheinmetall), optics (Zeiss), paper (Koehler), and adhesives (Tesa). It is ISO 9001:2015 and ISO 14001:2015 certified, with CE and ATEX compliance. Eisenmann has operated since 1951, delivered more than 2,800 projects globally, and has been part of the Deurotech Group since 2020; it established a wholly-owned Shanghai subsidiary in 2021 that is profitable and serves as a hub for Southeast Asia.

Revenue is generated primarily through one-time capital sales of custom-engineered plants, supplemented by an aftermarket service stream covering inspection, maintenance, retrofit, spare parts, modifications, and service agreements, plus technical documentation and consulting. GTM is consultative enterprise field sales led by a long-tenured Head of Sales (Dr. Peter Börgardts, since 1996) and CEO Tobias Werz, with no public pricing and individually prepared quotations. The aftermarket/service tail benefits from installed-base lifespans of 29+ years, creating a durable recurring revenue layer on top of project-based sales.
