In dialog on energy
efficiency and cli-
mate protection


When it comes to energy efficiency and renewable energies, “hot air” is all too often the only end result. In contrast, Geberit achieves tangible results by means of strict targets and the step-by-step successes set out in the sustainability strategy – plus groundbreaking pioneering projects. 2012 was another positive year in this regard.

“Geberit is continuously seeking
greater energy efficiency.
A block heating station operated
by biogas was therefore a logical
step for us in our efforts in climate
protection and CO2 reduction.”
Markus Heim, Head of Production at Geberit Pfullendorf (DE)


“What’s special about our coop-
eration is the fact that we produce
biogas while also satisfying the
most stringent sustainability crite-
Ulfried Miller, BUND Union for the Environment and Nature Conservation Germany


“The cooperation with Geberit is
of vital importance to us. Without a
reliable partner who supported us
from the outset and provided as-
surances for use of the biogas, we
would never have dared to con-
struct this plant.”
Georg Rauch, farmer and operator of Energiepark Hahnennest (DE)

After discussions with farmers and environmental experts, Geberit built a block heating station at its largest production site in Pfullendorf (DE). This block heating station is entirely supplied by a biogas plant under the ownership of four nearby family-run farms.

The Pfullendorf plant requires process heat all year round, thus offering ideal conditions for operating a block heating station. As a result, Geberit carefully examined the farmers’ proposal for a biogas plant, recognized the huge potential and set itself the goal of exceeding the minimum ecological requirements – not least in light of the fact that electricity generated from biogas is often the subject of heated debate. The result is a ten-point program that sets out all aspects required to ensure that biogas is produced in an environmentally and nature-compatible manner.

This pioneering project proves that Geberit knows how to reconcile ecological and economic concerns. It also represents a further step towards the optimization of energy management at all Geberit production plants and an active contribution to climate protection.

Im Dialog: Der Landwirt Georg Rauch
In dialog: Farmer Georg Rauch is one of the co-founders of Energiepark Hahnennest (DE). He is proud of his plant, which produces around 45 GWh of biogas a year.
Schritt 1: Rohgas
Step 1: In the fermenters, liquid manure, agricultural waste and plant substrates ferment, producing raw gas.
Schritt 2: Veredelung
Step 2: The raw gas is then refined into biogas in the gas processing plant and fed into the nearby natural gas pipeline.
Schritt 3: Stromerzeugung
Step 3: The block heating station at Geberit Pfullendorf (DE) produces a total of around 3.5 GWh of green electricity and uses an additional 4.1 GWh of waste heat for internal processes. This results in an impressive efficiency level of 81%.

Efficiency level


Roland Högger, Leiter Umwelt und Nachhaltigkeit
“What’s unique about this project is that
three completely different partners – namely
farmers, environmental experts and
industry – got together to work jointly on
finding the ideal solution. There is some-
thing symbolic about this partnership – after
all, sustainability is always about reconciling
various positions with one another.”

Roland Högger, Head of Environment and Sustainability


Excerpt from the ten-point program

  • At least 50% liquid manure or agricultural waste
  • No monocultures, meaning the proportion of corn is limited to 35%
  • No genetically modified organisms
  • 10% ecological compensation areas
