we are cyclize

We defossilize the chemical industry by providing syngas that is free of virgin fossil carbon through plasma reforming of mixed waste and CO₂.

The name Cyclize is derived from ‘to cyclize’. In chemistry, this refers to a reaction in which a carbon chain is closed to form a ring. We close the loop for circular carbon.

Research & Technology Invention

Our journey started with a research project about splitting CO2 to produce synthetic fuels for the shipping industry.

First Self-developed Power Supply

Our ongoing developments have led us to build our first plasma drivers with an output of 2 kW to power our plasma technology.

Proof-of-Principle

Due to our relentless efforts, we have achieved proof of principle by validating the fundamental technical principles behind our idea at a scale of 350 W.

Exist Research Transfer Grant

Successful technical developments enabled us to scale our plasma drivers to an electrical power of 2 kW in our high-efficiency plasma technology. Receiving the Exist Research Transfer grant laid the foundation for scaling to industrial scale.

Proof-of-Concept

The proof of synthesis gas production using waste and CO2 is a major milestone on our journey.

Series Seed Funding

Our successful seed funding enabled us to grow our team, strengthen our commercial activities towards defossilizing the chemical industry and fully focus on scaling our solution.

Proof-of-Plant

Scaling our technology by building our pilot plant with an electrical output of 50 kW was an important milestone that has positioned us as a leading company in the field of green chemistry.

Our Values

We believe sustainability starts with action

We’re not just reducing the need for fossil feedstock, we’re actively rethinking how carbon flows through our world. By giving new life to waste an emissions, we turn today’s problems into tomorrow’s solution.

We choose innovation with purpose

Our plasma technology isn’t innovation for innovation’s sake — it’s a powerful tool to solve urgent, global challenges like plastic pollution and CO₂ emissions. Though we would love to add: plasma is truly fascinating.

We build for circularity

Let's end the take-make-waste fate of carbon rich materials. Let's stop burning stuff. Let's recover and recyle to keep carbon in the loop. We change the linear life of products and materials to a circular one on a molecular level.

We’re here to create real impact

We help companies cut waste and emissions to meet their climate goals. Our technology has the potential to remove more carbon than it releases. That’s not just less harm, it’s positive change.
