In this ESL lesson plan for adults and teens, students watch a video and do a listening exercise about a startup in Berlin which is turning coffee grounds into reusable cups and saucers. It includes discussion questions, conversation, and other activities about coffee. Students also learn some important vocabulary terms, expressions, and phrases from the video. The grammar exercise features defining and non-defining relative clauses. There is also a quiz & review section with a bonus activity.

Kaffeeform, a Berlin-based start-up, has been creating coffee cups from recycled coffee grounds for the past three years. With the help of courier services, the company picks up used coffee grounds from cafés all across Berlin to create these eco-friendly cups.
