Circular Economy Accelerator
Accelerating Circular Innovation – Connecting Startups with Industry
The Circular Economy Accelerator (part of Circular Valley) is a leading accelerator supporting startups that drive the transition toward a circular economy. Located in the heart of Germany’s industrial Rhine-Ruhr region, it connects innovators with over 160 partners from science, industry, and policy. In their pitch, the team will share how their program helps scale technologies that close material loops — from batteries and electronics to advanced recycling — and how startups can join this global ecosystem to turn circular ideas into market-ready solutions.

Fraunhofer Community Talk: intensify cooperation and promote battery innovation into industrial adoption
The battery economy is complex — and it’s not getting easier. That’s why the Fraunhofer pitch will deviate from the usual 4-minute format. Instead, we invite our audience to share their views and experiences directly. Fraunhofer will open the discussion with a brief overview of the current mood in Germany’s battery sector, highlighting opportunities and challenges along the value chain. This sets the stage for a guided half-hour exchange between R&D and industry: What exactly does your innovation need today to be successful? And what would most accelerate your progress?
