For this festive episode, Claudi visited Julian Lechner who is the founder and inventor of Kaffeeform - a Berlin backyard startup that is producing reusable coffee cups from recycled coffee grounds. The idea and the story behind it is so brilliant and unique that Kaffeeform is getting a lot of attention and requests from all over the world, from Oslo to Korea.

​Julian started his business Berlin style: Without money, from a garage, pretty DIY - but with a big portion of passion and belief in his idea. He gave me a tour of the Kaffeeform headquarters in a Kreuzberg backyard and showed me how the production works.

​And how it works is so simple, yet fascinating: he goes around some local Kreuzberg coffee shops, collects their coffee waste, then dries it in little ovens, vacuum-seals it, sends it down to Southern Germany where the it gets molded with organic bio-polymers - no plastic, no toxics, no waste.

The result is one-of-a-kind: a beautiful, chocolate brown cup which is reusable and pretty much break proof. That’s what it means to go zero-waste, that’s what lies ahead of us.

I’m pretty sure you’ll enjoy this episode. If you love coffee - this is a whole new level. And if not, I promise you’ll still be inspired and get lots of good stuff out of it!

Hi Claudi, I love how insightful this podcast is.I own a Social coffee shop in Bucharest ,Romania and I would really want to do more for the local community: go zero waste and create more working place for disatvantaged people. Can we just visit Julian’s business and see more? Or can you help me with contact details? Wrote the address advertised on his site,but no answer.
Thanks a million !!!

Hey Andra – glad to hear you liked this episode! Kaffeeform is definitely one of my favorite zero waste projects in the city. Sounds great what you are up to as well. The contact on the website is right, but because the project is so awesome, they’re also very busy. Maybe try to send a little reminder?

andra November 19, 2018 at 8:43 am

Hei Claudi,

Thank you so much for your answer. Well it would be my 3rd reminder so most likely I’ll end up on a harassment list :)) My next option is to jump on a plane and visit them unannounced but I am thinking it would be a bit too much…again big chances of harassment charges :)) I’ve understood from the podcast they practice this knowledge sharing with people visiting them, but he did not mention how to schedule a visit. I’ve explored your podcasts more and it’s awesome the direction Berlin takes. I would love to bring this to Bucharest. Unfortunately consumerism is here way too powerful…and also harmful 🙁

Claudi November 26, 2018 at 5:50 am

Hey Andra, I’m sure it’s just a very busy time for them at the moment, Christmas is around the corner and there’s lots of exciting new things in the making. And about consumerism being too strong – be trustful and focus on those people who are doing the right thing and producing amazing eco-friendly alternatives. We still got a long way to go, but things are changing for the better, especially if people understand that being “green” doesn’t have to mean that they can’t live a nice lifestyle or buy beautiful things anymore from time to time 😉

Hello, I am a college student majoring in industrial design. The new recycling material that I thought of in the eco-friendly contest was already commercialized because you thought of it. I really think you are great and I applaud you. Can I explain your material on the page to explain the material in the contest for various uses of your kaffeefoam material?
