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. The two plants cover ten thousand square meters of production space and are expected to reduce the iron foundry’s natural gas consumption by up to 25 per cent by 2024, says Emil Brodersen, energy specialist at BIRN Group.

“We are constantly looking for ways to streamline our energy processes and optimize resource consumption and heat recovery has proven to have enormous potential for our company. The two plants have been in operation for just over two months and in that time have already saved us around 55,000 cubic meters of natural gas, so it’s a very interesting case for us – both from a sustainability and economic perspective,” Brodersen explains. BIRN expects to invest in a third heat recovery system in the spring, which will be connected to the foundry’s furnace filter, and a fourth recovery system in the summer of 2024. Through ongoing investments in recovery systems, among other things, BIRN hopes to eventually phase out the use of natural gas completely.
