My name is Evert Hagen (1967), born and raised in Amsterdam, Netherlands. Since my childhood I was interested and fascinated in the world of garden design and landscaping and this has become a recurring theme in my life. In 1991 I finished my studies at the Agriculture and Horticulture. In this period I have done at several renowned gardeners and garden designers and landscape architects study traineeships. After finishing my studies I took several specialist training and courses in the field of landscape architecture, culture, technology and management. In 1991 (simultaneously with training and courses), I started my construction company in Garden Design, Gardening & Maintenance. In this period I have realized and designed many beautiful projects in cooperation with well-known Dutch landscape architects, architects and interior designers. As of 2003, after many intense and busy years, I was ready for a new challenge and I decided to quit, partly due to the changing market in the field of sustainable development and innovation in the green sector in 2005. Since 2005 to 2013 I went to work for the largest Dutch company and landscapers. In this period I have occupied myself especially with sustainable innovation in the green sector.
In 2001 I came into contact with sustainable development in the areas of water, green and energy. The subject fascinated me and I have studied it further. As a result, I came into contact with BioNova. The product of BioNova intrigued me; purify pool water without the input of chlorine or chemicals. In addition to my active career, I have a seat in the technical committee for BioNova where I am primarily engaged in design, development, construction and realization. I also studied the field of green roofs and vertical greenery, whether or not in combination with solar technology, and in the area of water storage for reuse.
