New Management Structure at the WELTEC Group

Together with environmental services provider PreZero and Enagás Renovable, WELTEC BIOPOWER began construction of a biomethane plant north of Madrid in August 2026. Once operational, the plant in Colmenar Viejo will generate up to 60 gigawatt-hours of green energy annually, equivalent to the energy requirements of approximately 11,700 households or 30,000 residents.

Dedicated to sustainable energy for a quarter of a century: WELTEC BIOPOWER is celebrating its 25th anniversary in 2026, looking back on an impressive track record. Since its foundation in 2001, the company, based in Vechta, has evolved from a specialist plant manufacturer into an internationally sought-after full-service provider of biogas and biomethane plants.

In order to increase visibility of its service portfolio and improve access to information, WELTEC BIOPOWER has completely overhauled its website. The new website is a modern, clearly structured, international platform offering users quick, intuitive access to information on technologies, projects, and current developments.

Traditionally, progressive cavity (PC) pumps have been regarded as the best solution for the most demanding fluid pumping challenges. They excel at handling highly viscous, abrasive, and debris-laden media, making them particularly effective in wastewater treatment facilities.

To boost the GEMÜ Group’s international presence and make customers an even greater priority, the Hohenlohe-based valve manufacturer reorganized its Company Management in November 2025. Stephan Gehrig is a new addition to Company Management at the GEMÜ Group as the new Managing Director of Sales and Marketing.

Rising environmental standards, growing cost pressures, and a shortage of skilled workers: the demands on operators of municipal and industrial infrastructure continue to increase, making data-driven operations more critical than ever. At IFAT 2026, the leading trade fair for environmental technologies, Siemens will showcase how digital solutions help manage water quality, wastewater treatment and material flows in waste management more efficiently.
