BEST PRACTICE
Leiber GmbH, Bramsche/ Germany
EXECUTIVE SUMMARY
The Leiber GmbH is a modern biotech company and one of the leading producers of yeast for the food and
feed sector. The company develops, produces and distributes dried brewer’s yeast and yeast extract and is
currently developing products for the health and cosmetics sector.
GBE FACTORY MODEL
The company installed a new wastewater
treatment plant which also
produces biogas. The biogas fuels a
Combined Heat and Power Plant (CHP)
which produces electricity and heat
(CHP output: 190 kW electrical power/
240 kW thermal power).
The company cannot only meet it’s own
heating needs but also sell part of the
heat produced to a neighboring
company.

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.
