ENVIRONMENTAL &
ECONOMIC SUSTAINABILITY
The company had a really integrated approach to
adress the issues, not only focusing renewable
energy sources but also addressing the topics of
waste management and the use of chemicals in the
production process:
- integrated innovative waste-water treatment with
lower energy consumption, less waste and lees
need to use chemicals
- utilization of the biogas produced during the
waste-water treatment in a Combined Heat and
Power Plant (CHP)
- Induction of the electricity produced into the
public grid according to the regulations on the
feed-in tariffs
- utilization of the heat produced by the CHP plant
in the company’s own production as well as in a
neighboring plant
LESSONS LEARNT
This is a god example how different needs within a
company can be dealt with: the need for an new wastewater
treatment plant led to the increased use of
renewable energies not only to generate electric power
but also to meet the demand for heat.
