Remondis acquires century-old Siemer, preserving jobs, expanding recycling capacity, and strengthening European circular economy ambitions through strategic waste management growth.
Remondis, Germany’s largest and one of the world’s most prominent waste management companies, has expanded its operations further by acquiring Siemer, a century-old family-owned business headquartered in Vechta, northern Germany. The deal, which officially closed on January 1, 2025, was only recently revealed to the public. While the financial terms of the acquisition remain confidential, the transition is set to preserve all existing jobs at Siemer. According to information provided on its website, the company currently employs more than 85 people, who will continue to remain part of the business under Remondis’ ownership.
Both Remondis and Siemer have strong positions in Germany’s waste collection, recycling, and plastics management market. The companies operate within the framework of the country’s “dual system,” which governs the sorting and recycling of consumer packaging waste. Siemer, in particular, has invested heavily in recent years to strengthen its technological capabilities. At its Vechta headquarters, the company recently constructed a modern plastics sorting facility. This state-of-the-art plant is designed to play a crucial role in supplying sorted plastic feedstock to a major cross-border project: the planned chemical recycling plant being developed in Geelen, the Netherlands, by Sabic and Plastic Energy. The Geelen facility, which is nearing completion, aims to provide an advanced solution for converting difficult-to-recycle plastics into valuable raw materials, further supporting the European Union’s circular economy goals.
The acquisition of Siemer is part of Remondis’ broader strategy to expand its reach and capabilities through targeted acquisitions. Earlier in May 2024, Remondis purchased an 80% stake in Schroll Group, a French family-owned company headquartered in Strasbourg that specializes in waste management and recycling. With these strategic steps, Remondis is strengthening its foothold in both the German and European recycling markets, enhancing its ability to meet growing demand for sustainable waste treatment solutions.
Founded in 1934, Remondis has grown from a German family-run enterprise into one of the largest privately operated recycling, water, and environmental service companies globally. As of 2024, the company operates approximately 800 business locations across 34 countries spanning four continents. Employing more than 46,000 people worldwide, Remondis reported a turnover of €13.2 billion last year, underscoring its financial strength and influence in the global waste management sector.
Through the acquisition of Siemer, Remondis not only secures valuable infrastructure and expertise but also reinforces its commitment to driving innovation in recycling and advancing Europe’s transition toward a circular economy. For Siemer, integration into a global leader promises stability, resources, and opportunities for long-term growth, ensuring its legacy continues within a larger framework of sustainability and environmental responsibility.
