Rothaus uses reusable bottles that are filled up to 40 times before they are then returned to the material cycle as used glass.

The aluminium cap of the "Zäpfle" bottle is removed from the bottle in the sorting system using a specially designed machine, pressed and recycled according to type.

In total, an area of almost 1,000 m2 of collector pipework was installed on the roof of the picking hall, the loading hall, the sorting hall and the facade of the sorting hall

This pioneering achievement makes it possible to use the heat generated, for example, in our two bottle washing machines. The use of solar thermal energy leads to a further reduction in the use of fossil fuel energy sources.

In our sewage treatment plant, the used water is brought to almost drinking water quality before it is allowed to flow back into the ecosystem. By adding an anaerobic stage in 2023, we have already saved and will continue to save more than 100,000 litres of heating oil per year (CO2-savings: 270 tons per year).

By the way: In 1988, we needed 10 litres of water from our own sources to produce one litre of beer. In 1998 we only needed 5.9 litres - and today we have reached 4.5 litres.

But that's not all, because in order to achieve the ambitious goal of climate positivity by 2030, we are purchasing two wind turbines from a wind energy park that is being built in the immediate vicinity of the brewery.
