A Change of Scenery at Green Bay Broadway
Beginning in October 2019, the silhouette of the Green Bay Broadway (GBB) mill began to change. The first of two 400-foot stacks, a significant part of the Green Bay skyline for decades, started to be removed. The north stack was no longer being used for exhaust after GBB replaced a coal-fired boiler with a new natural gas boiler back in 2015. The mill is installing another natural gas boiler in late 2020 while the remaining south stack is scheduled for removal in 2021. The investment in natural gas boilers, a piece of the $80 million sustainability investments at GBB, helped the mill to decrease its emissions of nitrous oxide by 67 percent and sulfur dioxide by more than 80 percent. When the second natural gas boiler is activated later this year, the facility will be completely coal-free in its operations and will reduce emissions to near zero levels.
