Energy efficiency in practice

The two sites Greiner Bio-One in Kremsmünster and Greiner Packaging in Wartberg are veritable prime examples of energy-efficient activities. The following measures were carried out pursuant to the Energy Efficiency Act (EEffG).

Greiner Bio-One, Kremsmünster: Replacement of fluorescent lights with LED in hall lighting

The production site Kremsmünster (Austria) produces innovative medical products for customers in the health sector all round the world. Energy efficiency is an important topic at the Kremsmünster production site since this is among the biggest at Greiner Bio-One. In 2018, a total of 470 old fluorescent lamps were replaced there by a rail system with 273 LED lamps.

Thanks to this measure, the energy consumption was reduced by 196,308 kilowatt hours per year, the CO2 emissions were reduced by 54.97 tons per year and an annual cost saving of over 15,000 euros was achieved. With this project, we have been able to take another step in the direction of improved energy efficiency and reduction of emissions.

Greiner Packaging, Wartberg: Reduction of system pressure in the compressed air network

The production site Wartberg (Austria) produces plastic hollow parts (bottles and canisters) for customers from different industry sectors. To make sure the plastic parts maintain their desired shape, compressed air at various pressure levels is needed to inflate them. The production of compressed air is very energy-intensive and therefore expensive: the higher the network pressure, the higher the costs.

As the pressure in the high-pressure network was reduced from 40 bar to 33 bar, the option arose to also reduce the pressure in the low-pressure network, which produces the majority of the amounts required, from 12 bar to 10.6 bar. In this way, energy consumption could be reduced by 269,409 kilowatt hours per year, and CO2 emissions by 43.64 tons per year, and an annual cost savings of nearly 25,000 euros was achieved.
