Sustainability and Responsibility
We at Wenner acknowledge our entrepreneurial responsibility for active environment protection. The careful use of natural resources and the reduction of CO2 emission are the enter point of our internal environmental protection.
Covering 25 % of power consumption through photovoltaics
We rely on a photovoltaic system to produce approx. 25 % of our entire power consumption ourselves. 2,158 solar modules with a total rated output of 465.4 kWp serve to produce approx. 400,000 kWh of electric energy. This amount of energy roughly corresponds to the annual consumption of more than 130 average households. This means a yearly reduction of approx. 320,000 kg of CO2 emission to the environment. A display panel in the foyer of the administration building serves to impressively inform you about the capacity of our plant.
The utilization of renewable energy is common practice at Wenner.
Thermal solar systems - Hot water without CO2 emission
The Friedrich Wenner GmbH maintains a solar collector surface of 12 square meters for hot water generation through solar energy. Due to the change-over of the heating system approx. 3,000 kilowatt hours of oil / natural gas can annually be saved. This corresponds to CO2 reduction of approx. 2,100 kg per year with view to hot water generation alone.
Waste Management
The majority of the waste generated by Wenner consists of cardboard and paper. The waste paper is separated and collected from the residual waste for and transferred for recycling. Wherever possible, we try to economically use resources in order to avoid the generation of waste at an early stage.
Rainwater Utilization
Our modern rainwater utilization plant provides large amounts of rainwater. The rainwater running down from the roof is passed through a filter and collected in a rainwater storage tank. The rainwater is free of charge and need neither be treated nor transported over long distances. Saving rainwater is an important contribution to the careful use of precious resources.
Every citizen of Germany uses approximately 125 liters of drinking water per day. Flushing the toilet requires up to 40 liters alone. In industrial plants such as the Friedrich Wenner GmbH plenty of drinking water is used. This fact and our sensitivity for this precious resource caused us to install a rainwater utilization system.
