Crowdfunding since 2010
Undune is a documentary about an alternative place to do your “business”, the resurrection of an ancient method from the Amazons region and the battle of a few innovative people to dry up the wasteful culture of water toilets: Instead of using drinking water to flush away and destroy our manure, it can be transformed into a valuable resource - black soil or terra preta.

Nachdem Undune nun fertig ist, haben wir es endlich geschafft die T-Shirts, Beutel und Poster drucken zu lassen. Jetzt sind wir damit beschäftigt sie zu verpacken und zu versenden, so dass ihr sie bald in euren Händen halten könnt. Wir haben auch noch ein paar Beutel und Poster übrig. Falls noch Interesse besteht, schreibt uns einfach.

[English Version]

Since Undune is ready, we got enough time to order t-shirts, bags and posters. Now we are packing and shipping them for you to hold them in your hands as soon as possible. We have still some spare bags and posters. If some of you are interested, please, send us an email.
