Wevolver, in partnership with Growth Garage, the business accelerator from Mitsubishi Chemical Advanced Materials, Mitsubishi Chemical Europe, and  Mitsubishi Chemical Methacrylates, invited engineers, designers, entrepreneurs, startups, companies, and students to submit their ideas, technologies, and products as part of the 2022 Circular Economy Challenge. 

The challenge looked for innovators throughout the plastics circular economy who want to make use of advanced low carbon footprint engineering plastics or have developed innovative recycling technologies for advanced engineering plastics.

The challenge was open to participants in two key areas: 1. Recycling Technology and 2. Products & Parts. 

The Circular Economy  Challenge received over 60 entries from 17 countries. The Wevolver community vote had over 700 votes. 

Congratulations to all finalists and winners!

The winner of the Circular Economy Challenge

Category 1: Recycling Technology

Jeosal Materials Research Corporation


Jeosal Materials Research Corporation is a developer of economically viable, and ecologically sustainable solutions for the recycling and reuse of fiber-reinforced plastics from various sources including the automotive, aerospace, marine, and construction markets. Recovered products are channeled towards new applications in original or new markets. 

“Our business model is designed specifically for the recycling of fiberglass from marine vessels and reuse of the recovered products. It has the added advantage of successful deployment for fiber-reinforced plastics from other sources. 

In this model, we rely on specifically modified and enhanced recovered fibres and resin powder for unusual end-uses to ensure an economically viable and environmentally responsible venture,” describes Jeosal Materials Research Corporation’s CEO, Osayuki Osazuwa. 

Jeosal Materials Research Corporation will receive $25,000 of support from Growth Garage and their partners to test the technology at scale and strengthen their business model.

United States

Intermode manufactures and produces small robotic vehicles which they lease to customers for the purpose of automated delivery. The robots are designed to recapture some portion of their material value at end of life for reuse in future robots. 

“Coming from an automotive background, I know interior and exterior engineers can choose a huge range of different plastics to best target cost per individual component, but that can lead to a series of plastics that are individually "recyclable" but extremely difficult and cost-intensive to do so without tearing it down to small pieces. 

We intend to engineer the vehicle to maximum value and performance over its life lifecycle. We've designed the vehicle to be modular to easily break it down for recycling and keep materials pure for as long as possible," explains Internode Co-founder and CEO Arnolld Kadiu. 

“We'd like to investigate two different types of plastics. Structural fiber-reinforced thermoplastics to over-molded metal parts and UV stable thermoplastics to either thermoform or injection mold vehicle exteriors.”

Intermode will receive $25,000 of support from Growth Garage and their partners to build prototypes and work with the challenge partners to strengthen their business model.

Wevolver Community Vote winner

Wannes Van Laerhoven 


Wannes Van Laerhoven proposes a solution that recycles old tires and processes them into a filament suitable for 3D printing airless tires that can be used for various purposes. 

“I have already done tests with a filament made from recycled car tires and the results are promising. There is good elasticity and better grip than on the other TPE and TPU filaments I have tested without the rubber from car tires. The print quality is also much better than expected and surface quality is even better than the filaments without added rubber. Even though it's 3D printed with FDM it is very hard to see the printed layers unlike the normal TPE shore 45D printed prototype.”

The airless tire can provide a good damping effect because the lattice structures used in the tire have good energy-absorbing properties. This causes a more enjoyable ride for applications in micro-mobility and mobility devices such as wheelchairs. 

Wannes Van Laerhoven will receive $10,000 of support from Growth Garage and their partners to develop their idea further and create a working prototype.

Student Vote winner

Wannes Van Laerhoven also won the student prize. He will receive a further $5,000 in support from Growth Garage to develop his project, create prototypes and strengthen his business plan.
