Ecological, practical, good.
He grew up on chocolate. With renewable energy sources he has become an eco-manager. All in all, Alfred T. Ritter is a versatile man. In 1986, he and his sister took over the management of their parents' chocolate factory. A well-known brand, with the slogan: quadratisch, praktisch gut (square, practical, good). Its name: Ritter Sport

The Chernobyl catastrophe took place later that year. For Alfred Ritter, like many others, a defining moment: "I couldn' t simply carry on the way I had before." The consequence for Ritter: he further increased his dedication to the environment, and in 1988 founded a company which would soon develop into a leading organisation for ecological heating systems: Paradigma Energie - und Umwelttechnik.

In 1997, Ritter himself was declared “Eco-Manager of the Year" by the “WWF and the magazine “Capital". This was followed by the Prognos Future Awards Special Award. But more than anything, Alfred T. Ritter has always remained loyal to one thing: the environment.

"Art possesses the capability to stimulate our imagination. We believe youth is a valuable investment for the future, therefore we foster the promotion of young artists."
Marli Hoppe-Ritter

Passion for art has a long tradition in the history of the family Ritter. Thanks to Marli Hoppe-Ritter, an enthusiastic amateur artist and collector of constructional-concrete art, a close bond between the family business and art was established since the late 70's.

In 1985, she began to support young artists and to acquire modern art together with her husband Hilmar Hoppe. Since the opening of the MUSEUM RITTER in Waldenbuch in 2005, their collections, as well as temporary exhibitions of geometrical-abstract art, are open to the public.

Environmentally responsible action begins in-house, for instance, with the energy supply of the MUSEUM RITTER. Sustainability has the highest priority and hence the museum facilities are supplied with innovative renewable energy sources such as solar, biomass and geo-thermal energy, contributing to the reduction of CO2 emmissions.

A solar energy system of 47 CPC evacuated tube collectors is installed on the roof of the museum. It has a total output of 100 kW, covering 40% of the overall heat demand. Moreover, a wood pellet combustion unit works with four Paradigma Pelletti pellet boilers with a total output of 120 kW.
