Enna Klaversma finished her master Environmental Technology at Wageningen University in 2006. After that, she started at Waternet, the public water cycle company of Amsterdam and surroundings. There she worked on topics like sludge treatment and energy production. To help Waternet in making sustainable choices, she made life cycle analysis and carbon footprint calculations, e.g. for different types of activated carbon or methods to recover phosphorus. Since 2017 she works part-time as research coordinator for the Energy and Resources Factory (EFGF). The EFGF is the collaborative network organization of the Dutch water authorities that stimulates the recovery of valuable materials from wastewater.
