Having grown up in a family-run construction company, Franz had the opportunity to learn various trades and to delve deeper into the subject of “construction”. To scientifically underpin his technical knowledge, as well as his great interest in nature, he studied extra-occupational cultural engineering and water management and environmental engineering. Therefore, he can draw on more than 20 years of experience in the construction industry. His studies also aroused his interest in the topics of sustainability, ecology and circular economy, which ultimately led him to his thesis topic “Greywater Treatment Performance in Living Walls”. The topic did not lead him past alchemia-nova, where he now supports various projects from the technical side.
