To celebrate the release of The Cat in the Hat join the EWWR to discover sharing, creativity and making the most of what we already have to prevent waste.
What if you could have more fun without buying more things?
For this edition, the European Week for Waste Reduction is teaming up with The Cat in the Hat to inspire children, families and schools to rethink how they use the things around them.
Inspired by the upcoming animated film, the “Share your Things, reduce waste!” competition connects the Cat’s adventures with this year’s EWWR focus on Material Sufficiency: making the most of what we already have, sharing with others and discovering new uses for existing things.
Through playful activities, creative challenges and school initiatives, we can all learn that preventing waste starts with a simple idea: we don’t always need something new to have fun!
