SPECIFIC
WATER USE
As a manufacturing company, we require heat both for heating
our buildings and for our production processes.
Compared to 2017, our specific heat consumption at the Bruckmühl site has risen by 12%. The reason for this increase was the
fact that we added a new building, which now also requires
heating. Heat recovery was first used in late 2020.
To reduce the amount of fossil fuels used, we rely on heat
recovery systems across the company. In 2020, our new build
ing started operating a low temperature heating concept, in
accordance with which 80-90% of all heat required comes from
waste heat from production. Just like in the existing buildings,
all ventilation systems in the new building feature heat recovery.
This makes it possible to save 400,000 kWh of gas.
The Schoenenberger Magstadt site also has energy-efficient ventilation systems with 90% heat recovery in place. This translates
into annual gas savings of up to 300,000 kWh. Waste heat from
pressurised air and steam production is fed into a large buffer
storage with a capacity of 16,000 litres and fed back into the
heating or hot water system when required.

Next step: 100% renewable heat supply at the Bruckmühl site
Almost all options for heat recovery that are technically feasible
at the moment have already been used to save heat. As a result,
the next step to be taken at the Bruckmühl site will be to switch
from natural gas to self-produced heat.
Since 2008, two thermal solar energy systems for hot water
supply have been used for the laboratories and administrative
buildings and also feed into the building heating system.
It goes without saying that we are committed to using water sparingly — from
the sanitation facilities and the manufacturing process to the cleaning of machines
and equipment. If possible, water is used
more than once: For example, the cooling
water required in production is re-processed and re-used for hot water supply.
We plan to erect our own biomass heating plant on our premises
in 2023, which will produce heat for our production (steam) and
generate renewable heat for heating purposes.
