What idea will you
contribute to a
zero-waste future?
grand finals

Join us at the Grand Finals!

6 months ago, 190 students from 33 different countries started their journey with the ReThink Waste Challenge to come up with a circular and biobased innovation to reduce, reuse or recycle waste. After two milestone reports, entrepreneurial trainings and several workshops, only 46 of them are still in the competition. The top 10 teams will face the Jury during the Grand Finals.

Join us on 21 June in Omnia to meet the young entrepreneurs, innovators and companies leading the transition towards biobased economy! You will witness the reveal of the winner, vote for your favourite team and engage with keynote speakers Ugne Dirdaite (EU Bioeconomy Youth Ambassador) and prof. Cees Leeuwis (WUR) to make the transition happen. We promise you fun, inspiration and goosebumps from excitement.

Meet the participants

More than 190 students from 72 Universities in 33 countries are participating in the ReThink Waste Challenge. Their goal? To come up with a business idea or a prototype that contributes to a circular biobased economy.

It could be anything from a new material made out of biomass or a new technology to extract valuable products from biomass residue, to a more efficient production process or services that bring a zero-waste future one step closer.

From January until June 2023, with the support of top experts, they will develop their idea into a solid business proposition, ready to pitch to the jury and potential investors. Curious to learn more?
