Nettingsdorf supplies environmentally friendly district heating

A showcase project in terms of environmental protection and energy efficiency.

Less than a year after commissioning the new energy plants, Smurfit Kappa Nettingsdorf already has the next major project in the starting blocks. In cooperation with the Bioenergie Group, the leading corrugated base paper producer is building a plant at the Nettingsdorf site to generate environmentally friendly district heating from up to 25 megawatts of waste heat. Completion is planned for autumn 2022.

Sustainability in every (paper) fibre - this is the goal that Smurfit Kappa Nettingsdorf has been pursuing for many years with commitment and imagination. In cooperation with the Bioenergie Group and the municipality of Ansfelden, the company is building a plant to generate environmentally friendly district heating from waste heat by September 2022. Up to 25 megawatts of waste heat can be utilised in the process.

Smurfit Kappa Nettingsdorf's latest project is another milestone in the leading corrugated base paper producer's efforts to strengthen sustainability in production. In the production of the product Kraftliner - a packaging paper that in and of itself already internalises sustainability because it is made from renewable raw materials and is practically 100% recyclable - the company has been concerned for some time with making the manufacturing process as sustainable as possible.

Efforts began with measures that led to a significant reduction in the energy consumed in production - mainly electricity and heat (in the form of steam). After that, all energy generation at the site was made as efficient and environmentally friendly as possible. The Future Energy project with the construction of a highly efficient lye combustion boiler, where energy is generated from waste lye and from the wood components that cannot be used for paper fibres - i.e. biomass - is the lighthouse project in this area. Both lead to a strong reduction in the use of fossil fuels at the Nettingsdorf site. CO2 emissions per tonne of paper produced have been reduced to about 1/10 since 1990 - the beginning of international efforts to reduce CO2 emissions.

"The current project, which we are implementing together with the Bioenergie Group, is another important step towards promoting sustainability. We are making waste heat that could not be used in our production process, or only very poorly, available for the operation of a district heating network, thereby enabling massive CO2 savings effects for the heat consumers," Günter Hochrathner, CEO of Smurfit Kappa Nettingsdorf, explains the current construction project. This also significantly reduces the discharge of heat into the environment via exhaust steam and cooling water, which in turn supports Smurfit Kappa Nettingsdorf's decades-long efforts to reduce the pollution of air and water to a minimum.

The implementation period for the Nettingsdorf district heating project is very ambitious at 18 months. However, a quick implementation of the project is in the interest of all parties involved, because the funding pots for investments in sustainable energy supply are currently well filled. After all, Austria has set itself sustainable climate targets until 2030, and the federal government even wants to achieve climate neutrality by 2040. Waste heat projects like the one in Ansfelden are an important pillar of this strategy.
