Nabolagshager first invited Compostier to Norway for a lecture in the winter of 2018. After seeing the worm hotel at Circl, Amsterdam, Helene Gallis asked Rowin to come to Oslo and talk about the composting solution at their event.
This resulted in a nice collaboration and a first international pilot for Compostier in the summer of 2019. Together with youth from the neighbourhood Grønland in Oslo Compostier built three worm hotels to be tested in Oslo.
Joeri Bleumer made this short documentary about the pilot: http://bit.ly/OsloWormHotelCompostier
