Waste - how to avoid, separate, and recycle it. Which waste belongs in which bin? What is too valuable to throw away? And why is there litter almost everywhere? In this book, children discover what is in waste and where it goes after the garbage truck has emptied the bins. Flaps reveal how compost turns into humus, provide tips on reducing plastic use, and show what happens at a sorting facility. It becomes clear why recycling and incineration do not solve all problems and how to handle waste better.
