Maxim graduated with an MSc in Urban Environmental Management from Wageningen University, and an Engineer degree in Cadaster from Omsk State Agricultural University. He co-developed an entrepreneurial cooperative Metabolic, consulting and venture-building company; and a living lab De Ceuvel, city playground for innovation and creativity in Amsterdam. Recently he joined Delft University of Technology and Amsterdam Institute for Advanced Metropolitan Solution, with ambition to co-develop a decision-making environment, and tools for circular design.

Kees Roest completed his MSc in medical biology and his PhD in environmental sciences, focused on the microbiological aspects of anaerobic wastewater treatment systems (combining culture-dependent and culture-independent approaches). As a Marie Curie research fellow, he arranged new microbiology laboratories for the investigation of environmental bioreactor processes in Spain (Department of Chemical Engineering and Environmental Technology of the Universidad de Valladolid) and in the UK (Sustainable Environment Research Centre (SERC) of the University of Glamorgan). Currently he is working as a scientific researcher at KWR Watercycle Research Institute in Nieuwegein, the Netherlands. His research focuses mainly on innovative wastewater & reuse concepts and technologies. Furthermore, he is also the program coordinator of the KWR watertechnology projects supported by the Dutch governmental top sector policy.

Bastian Etter has worked on nutrient recovery from urine for the past decade. At Eawag, the Swiss Federal Institute of Aquatic Science and Technology, he first started on a nutrient recovery project in Nepal, and then joined the VUNA Project as its coordinator from the very beginning in 2010. The VUNA Project develop a system, which recovers valuable nutrients as a complete liquid fertiliser named 'Aurin'. In the meantime, Bastian has started up the company Vuna, which commercialises nutrient recovery and water recycling technologies. Part-time, he still works at Eawag, as the coordinator of the Water Hub in NEST, an experimental building and living lab near Zurich. Bastian holds an MSc Environmental Engineering from EPFL, the Swiss Federal Institute of Technology Lausanne.
