Alfred Zbären

Executive Director

On my own behalf: After more than 28 years of research and development (R & D) in the phytosanitary sector, I finished my employee relationship with one of the leading companies in the crop protection industry, to a long-cherished desire to fulfill and to become coworker and partner of the own company.

The personal interest in the issues of sustainability, the fascination for specialized yet simple products led me to Martin Burch AG, Humax® Bohrsonden.

I am very pleased that, together with my experience and the mentioned business, the basis for a new venture could be built. The business areas are now under the umbrella of GreenGround AG and will be led into the Future.
