GREEN BAY (From news reports) -- Green Bay Packaging says it's reached a milestone in its commitment to sustainable water use.

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

UL is a global safety leader, establishing the first industrial global standard of its kind.

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

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.
