WELTEC BIOPOWER GmbH reaffirms its independence as a leading manufacturer of biogas plants. Together with its suppliers and customers, the company continues on its path to international success. In 2023, WELTEC BIOPOWER GmbH separated from WELtec Holding GmbH. In the course of this separation, WELtec Holding changed its name to Nexogas Holding GmbH in July 2025. WELTEC BIOPOWER remains independent.
‘Our core business is and remains the planning and construction of modern, efficient biogas plants – from planning to commissioning,’ explains the management of WELTEC BIOPOWER. In contrast to Nexogas, which operates biogas plants and generates energy and whose shareholder structure consists of financial investors, WELTEC BIOPOWER GmbH, based in Vechta, focuses on the planning, construction and further development of biogas technologies.
Since its foundation, WELTEC BIOPOWER has built more than 400 biogas plants in 27 countries worldwide. Its own service unit also ensures that customers benefit from the optimal performance of the plants in the long term. As a manufacturer, WELTEC develops and builds plants, secures technical rights and brings innovations to the market. Operators, on the other hand, focus on the economic operation of existing plants and the marketing of their generated energy.
All technical rights to the plants developed and built by WELTEC BIOPOWER are the sole property of the company. In addition, WELTEC BIOPOWER will continue to work with its partners in the future. These long-standing supplier relationships guarantee proven quality and reliability ‘Made in Germany’.
With this statement, WELTEC BIOPOWER reaffirms that independent plant construction, international experience and reliable partnerships are the basis for our success – today and in the future.
Since its foundation in 2001, the WELTEC Group, based in Vechta, Lower Saxony, has been contributing to the success of the energy transition. The specialist has developed into one of the world‘s leading providers for the construction of biogas and biomethane plants. With the design, planning and construction of modern energy plants, as well as comprehensive services and sustainable utilisation concepts for the output streams, WELTEC accompanies projects from the initial idea to successful operation by the customer.
A particular strength of WELTEC BIOPOWER is its technological depth: all plant solutions are developed, designed and implemented in-house with interdisciplinary expertise. This in-house expertise enables complex projects to be planned precisely, individually adapted and technically supported in the long term. The use of stainless steel technologies ensures flexible substrate use, quick installation with little effort and a consistently high standard of quality regardless of location. To ensure economic efficiency, WELTEC offers mechanical and biological services after commissioning.
For WELTEC, proximity to customers and investors is of central importance. These include companies from the waste and food industries, agriculture and the wastewater sector. With a global sales and service network, the company has built over 400 energy plants in 27 countries on 5 continents.
