Germany is a global reference point in the development of technologies related to the circular economy. In a new study based on patent data, the country holds a leading position in terms of the economic relevance of inventions that support recycling, sustainable materials and resource efficiency.
Strong position in global patent rankings
Between 2010 and 2024, almost 62 000 technology patents were registered worldwide in areas linked to circular economy innovation, such as recycling metals and plastics and producing chemicals from renewable resources. Out of this total, German applicants were responsible for around 10 700 filings, about 17 per cent of all patents in the field. Only the United States registered more, with about 14 000 patents.
Germany’s strength is not only in quantity but also in quality. Patent quality here is measured by how often inventions are cited in new applications, which signals influence on further innovation. German patents in the circular economy field have been cited around 15 000 times over the past 15 years. This is more than Japan or the United States, two other major innovation centers.
Key areas of innovation
Two fields in particular show Germany’s innovative edge. One is battery technologies and recycling. As electric mobility expands, recycling batteries becomes critically important to reduce dependency on imported materials and to minimize waste.
The other area is circular construction, where Germany holds around 20 per cent of global patents. This reflects efforts to reuse materials and reduce the environmental impact of building projects.
Growing competition from Asia
Even with strong performance, Germany’s lead is under pressure. Countries in East Asia such as China and South Korea have increased their rate of patenting in circular economy technologies. China, for example, registered nearly five times more patents in 2021 than it did in 2010. South Korea and Japan also showed strong growth. This trend suggests that global innovation in this field is accelerating, and Germany may need policy support and investment to maintain its position.
Why do we measure it?
Technological advances in the circular economy have direct implications for sustainability goals and industrial competitiveness. Patents are a useful indicator of where inventions are happening and where future market leadership may emerge. In Germany, the innovation system supported by research institutions and industry remains strong. The country also retains a high share of European patent applications, reinforcing its role as a center of technological development.
