greenCHEM x CHARLE Open Innovation Challenge
Open Innovation Challenge
Industry meets green chemistry innovations
Tackle a real challenge from industry
In our Open Innovation Challenge, greenCHEM invites researchers and startups to submit novel, green chemistry solutions to a real-world industry problem. Selected teams receive mentorship from the industry partner and specialists within our ecosystem, as well as access to laboratories and equipment to further develop their technologies for two to six months. After this elaboration phase, teams pitch their ideas to a jury. The winning team receives prize money and may enter a partnership with the industry partner to continue developing their solution.
Our Partner: CHARLE
The Open Innovation Challenge features CHARLE premium haberdashery, a Berlin-based company that has been developing high-quality, circular narrow fabrics for a wide range of applications. Specialized in elastic and non-elastic bands made from natural rubber, organic cotton, linen, and TencelTM, the company pursues environmentally friendly, resource-saving, and socially responsible production methods throughout the entire value chain. With a spirit of innovation and a clear focus on sustainability, the company works to create textile solutions that will also benefit future generations.
The Challenge
CHARLE is looking for a non-fossil-based, biodegradable elastomer that behaves like rubber with raw material sourced in Europe. In other words, they seek a sustainable, biogenic alternative to natural rubber to reduce its upstream CO₂ emissions caused by long-distance logistics and to prevent future supply chain disruptions by being source in the European continent.

1. What we are looking for at the end of the challenge
We want elastomers based on non-fossil raw materials, able to be sourced in Europe, with the following characteristics:
Potential for biodegradability
Potential for high elasticity
Potential for extrudability
Nice to have:
Very good resilience
High tear resistance
Excellent chemical resistance
High tensile strength
Durability
Thermal stability
2. Possible approaches
Use of food or natural textile waste (natural fibres) or a combination thereof
Plant-based alternatives with low carbon footprint
3. Approaches not of interest
Waste or materials of fossil origin
Alternatives based on Russian dandelion (due to high carbon footprint and land use)
Plant-based alternatives with high carbon footprint
Rewards
Prize: Compete to win a 2.000€ cash prize

Q&A
-
You want to put your ideas to the test and contribute to making the industry more sustainable
You want to expand your network and meet people from industry
You want to do something that matters with your green chemistry skills
-
The Challenge is open to researchers and non-incorporated startups motivated to solve material challenges from the industry and able to come to Berlin for certain checkpoints, particularly the Kick-off and the Finale.
-
You can find the Terms and Conditions here.
-
All information about the IP conditions, you can find here.
-
greenCHEM will provide access to lab space and cover the costs associated with that for teams that require it. However, if your team doesn’t need a dedicated lab from greenCHEM, you may work in your current lab. In that case, we can cover some of the costs associated with participating in the challenge, even if we’re not the ones providing the lab.
-
No, at the moment of application your solution doesn’t need to have reached any of the established criteria. You only have to explain why is it that your team is confident that your idea could potentially reach the stated material characteristics. Should your team be selected to the second phase of the challenge (the Elaboration Phase), you will have the opportunity to work in the lab and further develop your solution.
The criteria play a bigger role at the end of the challenge. Then they are going to be used to evaluate the solutions presented and help the jury pick a winner. However, even at this point, there will not be hard targets that need to be reached.
And wildcard solutions are always welcome.

@Transfer Week 2025
The flagship event for open innovation in the chemical industry
Join us for the upcoming greenCHEM Industry Event "Industry on Campus" as part of Transfer Week 2025—where business meets science to drive the green chemistry transformation!
Here’s what to expect:
Program
In the morning we offer a further education course for SME’s about the topic Scale-Up in Chemistry - From Flask to Factory at the same location. Industry representives are invited to register for this opportunity aswell.
Who should register?
Industry on campus focusses on bringing Phds and Post-docs in contact with the industry. We especially invite SMEs and Startups to join.
Impressions from previous years:
Scale-Up in Chemistry - From Flask to Factory
Scale-Up in Chemistry
From Flask to Factory: an executve education course
Learn about scale-up for growth, market success, and risk reduction
Scaling up a chemical process can make or break innovation. This compact executive course will talk about actionable strategies for scaling up chemical processes in an industrial context, showcasing how green chemistry can help businesses to stay ahead: reducing costs, minimising risks, and accelerating time-to-market.
Hear directly from a successful startup and leading experts how integrating scaling up with green chemistry concepts can support SMEs with sustainable competitive advantages and stronger business performance. Throughout the morning, several rounds of moderated discussions will invite all participants to share their perspectives, address challenges, and ask questions freely in an open and collaborative atmosphere. This interactive format takes into account your key pain points and real-world experiences so that they are heard and incorporated into the rounds — hopefully leveraging the knowledge and connections needed to accelerate sustainable business growth.
