Net-Zero Water validation achieved by Green Bay Packaging

Green Bay Packaging has confirmed that its mill achieved Net-Zero Water in its production of 100% recycled containerboard paper, the first-ever UL with validation of this environmental claim.

“Environmental sustainability has always been at the core of Green Bay Packaging’s values,” says William Kress, President and CEO. “Our goal is to operate the most environmentally friendly mill system in the United States, with water quality in our communities a primary focus.”

The Net-Zero Water system at the Green Bay mill reduces water demand through use of reclaimed water and alternative water sources, offsetting the need for freshwater consumption. The goal in achieving ‘net-zero water’ is to transform a water-intense process into a more efficient process, returning more water to the water source than has been removed.

“Green Bay Packaging has been a strong stakeholder in developing a rigorous procedure for assessing site water balance,” said William Hoffman, research scientist in UL’s Retail and Consumer Products group. “By achieving Net-Zero Water Use based on the UL Environmental Claim Validation Procedure, Green Bay Packaging has demonstrated a strong commitment to sustainability and preserving water resources for future use. “

UL established the first industrial global standard of its kind with the UL 1397, Environment Validation Claim Procedure for Net-Zero Water, published January 27, 2022. Green Bay Packaging’s implemented water-use strategy to minimize the impact of water use on the watershed and increase water resiliency, parallels the net-zero concept.

“The net-zero water system is an investment in water technology that benefits community water resources while providing sustainable product innovation for our packaging customers and consumers. Establishing a reclaimed water loop with the local municipal wastewater utility is an integral circular economy innovation into our papermaking process,” says Lisa Bauer-Lotto, Director of Environment and Sustainability, Green Bay Packaging.
