Learn how to build a composting toilet with artistic bottle masonry elements
09. + 10. July at Rummels Bucht beer garden in Berlin
Composting toilets with urine diversion are an ecological and sustainable solution for collecting human feces and feeding nutrients back into their natural cycle. They work without water and help turning humanure, kitchen scraps and other organic matter into beautiful fresh humus. The collected urine is fermented by adding lacto-bacilli and then can be used as a potent fertilizer and composting agent.
In this workshop you can learn lots about humanure composting, terra preta and how to build a simple composting toilet on your own, manual included. On top we show you how to add some beautiful bottle masonry elements to the structure with self-made bottle bricks from recycled bottles and mud.
The workshop runs for two days. Two delicious, healthy, organic, vegetarian meals (lunch + dinner) are served both days. Accommodation is NOT included – if you do not live in Berlin and need a place to stay, please let us know. Spoken language is English (unless all participants speak fluent German). Both instructors are native German speakers and fluent in English.
The workshop fee is €150,-. Number of participants is limited to 12. We have a sponsorship program in place in case €150 is way too much for you. Just fill in what you can contribute in our registration form and we’ll see what we can do 😉
