Environment
Reducing consumption
At BIRN , we want to show responsibility by minimising our negative impact on the environment. We are therefore working proactively to reduce our energy consumption and increase our recycling of natural resources and surplus heat, and we are investigating how we can contribute positively to our surroundings.
As a result of energy-intensive processes at high temperatures and large consumption of raw materials, the world’s iron and steel production accounts for a large share of global emissions of greenhouse gases. As one of the largest foundry groups in Northern Europe, and thus an emitter of greenhouse gases, we are committed to continuing our work to reduce emissions connected with our operations and to share our results with stakeholders.
BIRN GROUP
Sustainability Report 2025
For the fourth year in a row, we are publishing a sustainability report for the entire BIRN Group.
Mapping of carbon emissons
In close collaboration with PwC, BIRN has prepared a double materiality analysis. The analysis gives us a 360-degree view of the entire group in relation to the impact we have on the outside world, and how external factors impact us as a group. It’s a powerful starting point for defining concrete goals for how we can minimise our negative impact on the climate and environment, and identifying focus areas that are beyond our own control but which we need to take into account in our business operations.
In relation to the climate and environment, it is particularly BIRNs consumption of electricity, natural gas and resources and our production waste that have a significant impact on our surroundings, making these also the key areas to work with to minimise negative impacts.

Energy consumption
Electricity consumption is rising throughout society, and one way to cater to the increased demand is to improve the balance between demand and production. This applies in particular to the power we use for melting, holding furnaces, casting and the machining of cast iron.
Foundry as industry frontrunner in the EU
The consumption of electricity is increasing throughout society and one of the ways to meet the increased demand is by regulating the consumption of the power sent out to consumers such as industrial companies.
Melting furnaces to help improve energy efficiency
BIRN has recently completed an AI-project in cooperation with pour-tech AB to optimize dosing of molten iron from casting machines into molds to reduce energy consumption.
Natural gas consumption
BIRN Group has a goal of using no natural gas, in line with our customers’ expectations. Therefore, we have made investments in alternative forms of energy, and have a strong focus on increasing the share of renewable energy in our energy mix
BIRN Group continues to phase out natural gas
At BIRN in Holstebro, where natural gas is primarily used for comfort heating, consumption has already been significantly reduced. Over the past three years, natural gas consumption has halved as a direct result of targeted investments and a systematic approach to energy efficiency.
Surface treatment plant markedly reduces natural gas consumption
Since 2021 BIRN has been treating components in a new surface treatment centre where new technology makes it possible to coat castings with a water-based ED paint, rather than the solvent-based paints used previously.
BIRN reduces natural gas consumption by 25% using heat recovery
BIRN aims to reduce its natural gas consumption by around 25 per cent by 2024. The reason is the recirculation from two new heat recovery plants that utilize the excess heat from parts of BIRN's production to heat the rest of the company.
Resource consumption
Circular Business Model
The BIRN Group’s business model is based on a circular economy mindset. For us, it has long been common sense to consider how we use and consume the planet’s resources.
Recycling of scrap
We are committed to reducing our negative environmental impact, and recycling scrap is a crucial factor in this.
Recycling of casting sand
We use large amounts of sand in the casting process. All sand is reused several times. To ensure good sand quality, two per cent of the casting sand is replaced with new sand on a daily basis.
