The Story of Circu Li-ion: Building the Future of Urban Mining

Sometimes the most impactful companies start not with a breakthrough technology, but with a mother’s lesson about consumption. In a recent episode of Category Visionaries, Circu Li-ion CEO Antoine Welter revealed how early experiences shaped his company’s mission to revolutionize battery recycling.

From Consumer Psychology to Circular Economy

“When I mentioned my mom was more wild growing up, teaching me anti consumption and take care of nature and all those things,” Antoine reflects. “I think it only when I was 16 and didn’t get a new pair of Nikes, I always thought that was super annoying. But later on, getting a little bit older, I realized how smart that actually was.”

This early lesson in mindful consumption would later combine with Antoine’s consulting experience, where a pivotal conversation with his manager sparked a realization. “I got feedback from my first manager director saying, antoine, you’ll be extremely mediocre at the low levels, but I’m sure you can be a great md.” The timeline to impact felt too long: “I calculate and say, okay, well, I’ll need another eight or ten years to get there. So fuck this. I need to do something different.”

Finding the Right Problem

The journey to Circu Li-ion began with extensive customer discovery. Through his network, Antoine received crucial insight from an automotive OEM executive who suggested exploring battery recycling. The market signals were clear: “Today people pay to get rid of a battery. So there was clear that there is a real problem.”

The technical validation came through partnership with co-founder Dr. Xavier Cohen, who “read over 100 academic papers stating that there was something real to be solved.” This combination of market need and technical possibility formed the foundation for Circu Li-ion’s approach.

Starting Small to Scale Big

Rather than immediately targeting electric vehicle batteries, Circu Li-ion began with micro-mobility: “We focused on that market in beginning simply… these batteries basically die twelve to 18 months after they entered the market. And if you look at a car battery, it takes a lot longer between let’s say five and eight years in an optimal case until they come out of the market.”

This strategic focus allowed them to build their “battery library” – developing robots smart enough to handle an increasing variety of battery types. As Antoine explains: “We started off with micro mobility batteries. So e bikes and scooters, emo pad. Then we added power tools on demand from customers. Then we added electric car batteries, then we added drone batteries, energy storage batteries.”

Building the McDonald’s of Battery Upcycling

Rather than constructing massive centralized facilities, Circu Li-ion developed a distributed model: “We set up the process, we provide the technology and the menu card, but then we roll out with recyclers and oems that they can implement our solution on their sites.” This approach enables rapid scaling while navigating complex regulations, requiring just 30 square meters of space within existing facilities.

The Future: Making Urban Mining a Reality

Looking ahead, Antoine envisions Circu Li-ion’s role expanding beyond just battery recycling: “That Circu Li-ion has enabled urban mining by being able to dismantle all sorts of different batteries, but also maybe adding other products that are worth dismantling to our portfolio.”

The goal is to make the circular economy not just an environmental aspiration but an economic reality. With over 160 planned installations across Europe, Circu Li-ion is working to transform how we think about waste – not as a problem to dispose of, but as a resource to be mined and reused.

In a world increasingly focused on sustainability, Circu Li-ion’s story shows how combining operational innovation with environmental impact can create lasting change. What started with a lesson about consumer choices has evolved into a vision for making “urban mining and the Circu Li-ion economy not only a green bubble reality, but a mass in the mass, a reality.”
