How Paper Mills Are Going Sustainable

The hulking pulp and paper mills built many decades ago in Wisconsin, Michigan and other Midwestern states have had their share of environmental impacts.

But the mills were decades ahead of the game in adopting technology now seen as an effective tool to fight greenhouse gas emissions and environmental impacts. That would be the use of combined heat and power (CHP, also known as cogeneration), promoted by President Obama with a 2012 executive order and lauded by environmental and energy efficiency advocates.
