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.

Wir haben 7 Tage vor dem Ende unserer Kampagne das fehlende Geld zum Kampagne dazugegeben. Das war uns unter anderem deshalb möglich, weil wir von der EM-Scheiz-AG, der Christoph-Fischer-GmbH und der Multikraft GmbH zusätzliche Unterstützung zugesichert bekommen haben.

Vielen Dank an euch alle für eure großartige Unterstützung. Nun können wir damit beginnen unseren Film fertigzustellen. Heute beginnen die ersten Drehs für die letzten Szenen. Ab nächster Woche beginnt die Postproduktion.

7 days before the end of the campaign, we put in the last part of the money ourselves. That was possible because we were assured additional support by the EM-Scheiz-AG, Christoph-Fischer-GmbH and Multikraft GmbH.

Thank you very much for all of you great support. Now, we can start to finish our film. Today start the first shootings for the last scenes and next week we will start with the postproduction.
