The Atlanta Journal-Constitution said Monday that its printing plant became the nation’s first newspaper press to win the U.S. Zero Waste Business Council’s Gold level certification for diverting waste from the environment.

The Gwinnett plant, which prints the AJC and other newspapers for local distribution, was awarded the certification for diverting nearly 99 percent of its waste — more than 5,000 tons annually — from landfills or incineration.

The reductions come through recycling, reusing, composting or reducing usage of materials.

“As a Cox company, the AJC is proud to participate in the Cox Conserves sustainability program,” said AJC Publisher Amy Glennon. “The AJC is committed to operating in ways that reduce our environmental impact, as well as reporting on the environmental issues that touch our community.”

The AJC is part of Cox Media Group, a publishing, digital media and broadcasting subsidiary of Atlanta-based Cox Enterprises.
