Dedicated to sustainable energy for a quarter of a century: Weltec Biopower is celebrating its 25th anniversary in 2026. Since its foundation in 2001, the company, based in Vechta, Germany, has evolved from a specialist plant manufacturer into an internationally sought-after full-service provider of biogas and biomethane plants. Today, Weltec Biopower carries out projects all over the world—from planning and construction through to commissioning and bespoke service packages. Below, Tobias Gerweler, head of Weltec Biopower’s technical division, discusses the company’s international experience, technological expertise, and reliable project delivery.

MPT: What are some of the factors that have led to Weltec Biopower’s longevity?

Tobias Gerweler: A key factor in our success is our unwavering focus on quality and customization. Thanks to in-house development and the use of proven stainless steel technology, we produce durable, robust systems that are tailor-made to meet our customers’ specific requirements and substrates. This approach ensures not only efficiency but also long-term cost-effectiveness. 

MPT: What changes have you seen in your time with the company?

Tobias Gerweler: Over the past twenty-five years, Weltec Biopower has evolved alongside a market that has undergone fundamental changes. While the initial focus was primarily on agricultural biogas plants, industrial applications are now becoming increasingly important. Processing organic residues from the food industry, waste, or sewage sludge requires complex technical solutions.

Recognizing this shift early on, Weltec Biopower has expanded its portfolio to include everything from sanitization and material separation to the efficient processing of fermentation residues, offering comprehensive solutions for the modern demands of the circular economy.

MPT: How have those changes prepared you for the future?

Tobias Gerweler: The company has also laid important structural foundations for the future. Following the sale of its plant construction division, Weltec Biopower now focuses exclusively on developing, designing and constructing innovative biogas plants. This core business is complemented by a comprehensive range of services designed to ensure consistently high plant performance and operational reliability.

With its clear positioning as an independent technology provider, its own technical rights and long-standing, reliable partner networks, Weltec Biopower remains true to its mission: innovative and cost-effective solutions “Made in Germany” for international markets.

MPT: Where do you see Weltec Biopower heading in its second twenty-five years?

Tobias Gerweler: In light of the growing demand for climate protection, a circular economy and a sustainable energy supply, the company sees significant potential for growth in the coming years. The conversion of organic waste into energy is becoming increasingly important worldwide, and Weltec Biopower is well placed to play an active role in this development.
