Hamburg Engineers
for Thermal Treatment Plants

The general planner for your energy and environmental technology plant is

We are an experienced, multidisciplinary association of Hamburg engineering companies and have been collaborating with each other for over 20 years. Whether waste or sewage sludge recycling, district heating or industrial power plants – we are the perfect choice for all planning requirements. As general planners, we will guide you through all phases of your project, from the preliminary study on through to commissioning.

The was founded in 2001 in order to bundle the various specialist disciplines under a common roof. The idea originated with Dr.-Ing. A. Nottrodt, who was a member of with his engineering office and remained our acknowledged mentor until his death.

The chosen form of cooperation has proven itself in many large projects and has shown significant promise for the future.


Our engineering offices combine extensive knowledge of the targeted subject matter added to many years of experience.

The members of connect the latest expertise with experience taken from planning, the authorization, the construction and the operation of multiple plants both nationally and internationally. Together, we cover all disciplines from process and energy technology to electrical engineering and control technology, as well as building services and construction technology.
