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

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?
