Borne by the desire to preserve the life's work of her husband Josef Grünbeck, namely his company, and at the same time to safeguard the location and jobs, Loni Grünbeck set up the “Loni and Josef Grünbeck Foundation” in 2010. The institution pursues solely and directly charitable and benevolent goals. The foundation also holds majority non-saleable shares in the Grünbeck company, and therefore plays an important role in securing the company's future.
The foundation's goal focuses on Grünbeck's core business activity: water treatment. The foundation therefore primarily promotes research, development and education in the field of water treatment. The foundation also helps the company's employees and citizens who live in the town where the company is based, Höchstädt a. d. Donau, who are experiencing health or financial problems. Specifically this targeted support of people in their direct vicinity was always a matter close to Josef and Loni Grünbeck's hearts.
The foundation's executive board includes the director Dr. Günter Stoll. The board of trustees, which advises and supports the board, consists of the members of the Grünbeck Wasseraufbereitung GmbH advisory committee.
