For this edition we spoke to Ariane Krause, engineer, researcher, and founding member of KAnTe (Kollektiv für Angepasste Technik - in English, “Collective for Appropriate Technology”) about their work around sustainable technologies. Focusing primarily composting, charcoal and favourite topic, compost toilets, they host workshops and produce educational materials as well as coordinating larger projects. We take a deep dive into their ongoing efforts to bring activists, small companies, and researchers together for collaborative research to lay the groundwork for a campaign to change the legal framework around waste processing in Germany that blocks more widespread use of compost toilets.
