Recycling
BIRN’s iron foundry is a large recycler. The raw material we use in the product is steel scrap, which is melted down using electricity and made into cast iron in various alloys. The molten steel scrap is converted into castings on Disamatic moulding systems using moulding sand. The moulding sand and used moulding sand are made up of a mixture of quarry sand and beach sand, together with bentonite (clay), coal dust and water.
In cooperation with the environmental authorities among others, it has been demonstrated that used moulding sand can be utilised in building and construction work. For example it can be added to asphalt and grey cement. Work has been done in cooperation with the Danish Environmental Protection Agency to develop new technology so that auxiliary materials can be used for longer in production before being recycled in another industry.

External environment
Over the years the business has made a number of very substantial environmental investments with a view to improving both the external and internal environment. In order to reduce dust emissions, ten highly efficient bag filter systems have been installed and connected to chimneys measuring 40-50 m in height. In the new environmental approval, the limits for atmospheric emissions have been changed to 10 mg/m³. BIRN’s emissions are below 3 mg/m³.
Noise levels have been reduced by replacing and enclosing fans and plant. Odour pollution has been cut by installing a washing system to remove most of the amines that cause odours in the atmospheric discharges.
Internal environment
The internal environment includes hot, dusty and noisy processes. At BIRN we are investing continuously in cleaner technology with a view to reducing energy consumption, noise and waste.
Influencing the attitudes of the workforce and making ongoing improvements in health and safety throughout the business are helping to limit the number of industrial injuries and the incidence of absence owing to illness caused by industrial injuries. Working groups involving both management and employees have also been working continuously on workplace assessments as a natural part of BIRN’s safety work and in order to ensure that health and safety continue to improve
