from the foundation until today

show History


The principles of our environmental policy are based on a belief in the future and a sense of responsibility towards the natural and built environment, as well as towards our fellow human beings and future generations.

During the planning of construction projects, we examine the specific impact on the environment and prioritize the individual environmental aspects according to the knowledge we gain. Projects that have a significant impact on the environment are designed to be as environmentally friendly as possible, using appropriate planning and construction measures. In the selection of our suppliers, we prefer those who act according to ecological rules and follow our environmental policy.

Rytz AG is committed to sustainable ecology. Energy efficiency is a top priority. 2000 m2 photovoltaic power plant on our production halls covers 40% of the annual energy demand. In addition, the plant feeds the power grid with energy for about 10 single-family homes per year.

An increasing proportion of our vehicle fleet is powered by electricity. Our goal is to equip the entire fleet with electrically powered vehicles in the future.
