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.

Mapping of carbon emissions

In 2022, BIRN has partnered up with ReFlow. The purpose of this collaboration is to map carbon emissions from our processes and products. The collaboration is part of the sustainable strategy for the entire BIRN Group and will help set even more ambitious and realistic goals in the future.

We have achieved our goal of establishing comparable and in many places automated data collection, so we have an overview of how our carbon emissions are distributed in the three different scopes.

Energy consumption

Optimising our energy consumption is one of the areas in which we can actively reduce our climate footprint. This applies especially to the electricity we use for melting, hot holding, casting and treatment of cast iron.

Natural gas consumption

Every year, BIRN casts about 45,000 tonnes of cast iron and accounts for the vast majority of our natural gas consumption in BIRN Group.
Our goal is to become independent of fossil fuels by 2040. We have made investments in alternative forms of energy to this end, and we have a focus in all factories within the BIRN Group on increasing the share of renewable energy in our energy mix.

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.
