Sustainable Chemistry on Stage: Global Start-ups Drive Change at Impact Festival
Ten finalists of the ISC3 Innovation Challenge 2025 compete for a total of €25,000 in prize money in the finals at the ISC3 Investor Forum
Ten international start-ups will present their groundbreaking solutions in the field of Sustainable Chemistry at the ISC3 Investor Forum 2025. The seventh edition will be held as part of the Impact Festival on 26–27 November 2025 at Messe Frankfurt. The event will culminate with the Award Ceremony of the ISC3 Innovation Challenge – this year dedicated to innovations in Sustainable Chemistry and Climate Change.
The winner will receive the main prize of €15,000, alongside two “Special Impact Awards” of €5,000 each. Hosted by the International Sustainable Chemistry Collaborative Centre (ISC3), the Investor Forum promises an inspiring two-day programme highlighting how Sustainable Chemistry can drive transformative change across industries and regions. Visitors will discover a range of innovations advancing climate change mitigation and adaptation – from chemical recycling of hard-to-recycle plastics in Luxembourg and Japan, to climate-smart building panels in Azerbaijan, long-range electric vehicles in Bangladesh, and women-empowering biomass solutions in Zambia. Other breakthroughs include bio-butadiene production (to produce synthetic rubber, plastics, and everyday products) in the Netherlands, low-carbon concrete in Ghana, renewable aviation fuels in Germany, and soil-enhancing nanofibers in the United Arab Emirates (UAE).
Harnessing Impact Investment for Sustainable Chemistry Innovation
The ISC3 Investor Forum connects start-ups, scientists, investors, and decision-makers to foster collaboration and investment in Sustainable Chemistry. “We are excited to host the ISC3 Investor Forum at Impact Festival for the second time," said Dr. Alexis Bazzanella, Director of the ISC3 Innovation Hub. "With this year’s topic, ‘Sustainable Chemistry and Climate Change,’ the forum showcases start-ups tackling challenges like waste, energy supply, and carbon emissions, providing innovative solutions for a sustainable future.”
Over two days, visitors can look forward to pitches from ten global start-ups, an investor talk, and a masterclass on Identifying Sustainability in Chemical Innovation.

About ISC3
The International Sustainable Chemistry Collaborative Centre promotes Sustainable Chemistry for a sustainable world. ISC3 supports the chemical industry and chemical-related sectors in their transformation process through sustainable, innovative approaches from Sustainable Chemistry. The goal is a circular economy that integerates multiple aspects of sustainability throughout the entire product life cycle and encourages a shift in stakeholder behaviour. To advance the dialogue between different sectors and actors worldwide, including Europe and other regions as well as emerging and developing countries, ISC3 follows a multi-stakeholder approach with the networking of policymakers, public and private sectors, education, science and society. It contributes to international chemicals policy, develops professional and academic training programs, advises companies, and promotes start-ups and research. Founded in 2017 by the Federal Ministry for the Environment, Climate Protection, Nature Conservation und Nuclear Safety (BMUKN) and the Federal Environment Agency (UBA), the centre is implemented by the German Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ; Englisch: Society for International Cooperation) and supported by the Society for Chemical Engineering and Biotechnology (DECHEMA e.V.) as ISC3 Innovation Hub. www.isc3.org
