2.600 kwP - one of the biggest photovoltaic power plants in Austria

In 2021, nearly 8,000 photovoltaic modules were installed on selected roof areas of Laakirchen Papier in cooperation with Heinzel Energy.
The photovoltaic power plant delivers 2.6 GWh electricity annually - enough to supply up to 600 households with electrical energy. In addition, nearly 700 tons of CO2 are saved every year.

In summer 2019, the "Danzermühl" hydropower plant went into operation after a 2.5 year reconstruction in cooperation with Heinzel Energy. The plant produces 45 GWh of sustainable electricity for our paper mill every year. This corresponds to an annual electricity requirement of over 11,000 households.

45 GWh of electricity from hydropower plant

The reconstruction of the hydropower plant has many ecological and economical advantages. On the one hand, the merging of the two barrages "Danzermühl" and "Kohlwehr" resulted in a yield increase of 150%. This measure increased the drop height of water by 2 meters. As a result, we reduced our CO2 emissions by around 11,000 tons per year compared to purchasing the same amount of energy from the current local electricity mix.
Furthermore, by merging the two barrages, the free flow of the river Traun was extended which improves the habitat for many fish species. A fish ascent and descent enable fish and small animals to swim unhindered along the Traun. The near-natural design of the underwater area also serves to improve the living conditions for the aquatic organisms in the Danzermühl hydropower plant area.

About 750,000 tons of waste paper are processed on site using a special technology each year.

Valuable raw material: paper for recycling

Conservation of valuable primary resources such as wood.
According to the latest findings, the fibers gained from waste paper can be reused up to 25 times.
Lower energy consumption and use of chemicals through the use of secondary fibers (waste paper).
When cleaning waste water, high-quality biogas is created for heat generation (saving natural gas and CO2).

Paper recycling

Wastepaper as raw material for sc paper production is processed in the deinking plant.
Wastepaper as raw material for containerboard production is processed in the RCF plant.

Efficient energy management

When cleaning the waste water (RCF system), high-quality biogas is created for heat generation. This helps to save natural gas and CO2.
The gasturbine co-generation plant enables 2/3 of the energy supply and a complete heat supply of the plant.

Wastewater treatment plant

We guarantee the excellent water quality of the river "Traun" by our extensive wastewater treatment. Additionally, we secure an ecological habitat for fish and small animals.

Thermal treatment of product residues

Residues are recycled in a fluidized bed boiler. We work 99% waste free.
