Mill Operations: Green Bay Mill

A continuous commitment to our customers, quality and the environment

A fully integrated pulp and paper mill manufacturing recycled containerboard; the Green Bay Mill Division is committed to continuous improvement. In fact, this mill has set industry standards with a completely closed process water system, dual industry certification, and by earning recognition as a Wisconsin Green Masters company.

Today a 100% post-consumer recycled mill, the Green Bay Mill was built in the 1940s as a 100% virgin corrugating medium mill, the world’s first to use the NSSC pulping process. This process allowed corrugating medium to be manufactured using northern hardwoods in place of straw, which was the industry standard. Research & development by mill visionaries in a quest for continuous improvement, led to the incorporation of recycled fiber to the raw material mix in 1957.

In the late 1980s, the recycled content was up to 50%. Between 1989 and 1991, the facility was completely redesigned, rebuilt, and converted into the state-of-the-art recycled containerboard mill it is today.

Closed-Water-System

In 1992, the Green Bay Mill became one of the first linerboard mills in the world to institute a totally effluent free (TEF) water system. No direct discharge of process waste water is sent into the adjacent river.

Recovery-Recycle Closed-Loop System

Because Green Bay Packaging is continuously improving our sustainability efforts and embracing greener supply chain management, we partner with customers to optimize the collection of OCC recovered in their recycling processes. That effort regenerates corrugated shipping containers with fewer resources while reducing our carbon footprint. Using post-consumer waste is an innovative best practice for supply chain sustainability.

FSC® and SFI® Chain-of-Custody Certified

The Green Bay Mill is certified by the FSC® (Forestry Stewardship Council™) and SFI® (Sustainable Forestry Initiative®) Chain-of-Custody since June 2008, making it one of the first in North America.

Our certifications prove we’re dedicated to promoting Sustainable Forest Management. The Green Bay Mill is audited yearly by an independent third-party to ensure compliance with the certification standards.

Green Masters

On Dec. 8, 2010, Green Bay Packaging became one of the first to be recognized as a Green Masters company at the Wisconsin Sustainable Business Council Annual Conference, a first for a corrugated box company. In fact, we scored in the top 20 percent of the points-based program.

The Wisconsin Sustainable Business Council launched the Green Masters program as a way to recognize and support Wisconsin businesses and institutions that are committed to sustainability. As a pilot company, Green Bay Packaging has helped the Green Masters program evolve into a valuable tool for companies and their sustainability goals.
