Our company Herbst Umwelttechnik GmbH has been active in the field of environmental protection for more than 38 years. 
We plan, build and maintain process plants for gas, water and sludge treatment. 
We focus on the development of clean, efficient and economical process technologies.
We will be pleased to find a solution to your problem together with you.


In addition, we offer fermentation processes which allow the conversion of rice straw, soy straw and even elephant grass into biogas.
With our special expertise in the separation of hydrogen sulphide (H2S) from the gas and water phase as well as the removal of arsenic and phosphate in the field of drinking water treatment, we are able to offer a wide range of solutions.

In addition to the construction of our standard plants for the

  • Gas purification

  • Water purification and

  • Sludge treatment

we also build silo plants and dosing plants for

  • Flocculation polymers

  • Potassium permanganate and

  • FerroSorp® DG

Our special processes include systems for
separation of

  • Uranium from the water phase with the polymer aggregate GoPur® 3000,

  • Vinyl chlorid,

  • Hydrogen sulphide and chlorinated hydrocarbons as well as siloxanes from landfill gases,
  • Hydrogen sulphide from biogas

  • Bank filtrate water treatment

  • Ammonium from the water phase

Special systems for

  • Bank filtrate water treatment for drinking water production

  • Biogas plants for e.g. straw fermentation

We use plastic waste for decentralised electricity generation and refrigeration if desired.

With the help of our newly developed decentralised small incineration plants, plastic waste and other organic residual materials can be thermally utilised to produce superheated steam or electricity.

By using an absorption chiller, the waste heat can be converted into process cooling.

The electrical plant output varies between 100 kW
el and 3 MWel.
