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.
