WELTEC BIOPOWER plans and produces complete biogas plants made of stainless steel and distributes them worldwide. With now more than 80 employees, more than 300 plants in Europe, the U.S., Cyprus and Japan have already been realized.

In 2011, the WELTEC BIOPOWER GmbH celebrated its tenth anniversary and is a biogas plant manufacturer in the first hour. On the basis of the modern approach of experienced engineers, the company offers from Vechta, Lower Saxony, complete biogas plants from one source and has evolved into a leading supplier of biogas plants.

The strength of the medium-sized company are customized solutions - from compact plants on large computer-controlled plants in the megawatt range, waste recycling plants, and biogas parks with gas processing technology.

The plants have a modular structure: In WELTEC BIOPOWER only proven system components are used and developed much of the technology along the entire value chain itself:

  • Fermentation technology
  • Stirring
  • Control technology
  • Sanitation systems, and
  • Digestate processing solutions originate from the company.

WELTEC builds stainless steel fermenter, because the hydrogen sulphide and ammonia compounds contained in biogas corrode unprotected parts. This ensures a long service life. Production capability also ensures a consistently high standard regardless of location and provides a well above the industry average export rate.
