In order to serve the customer, support the community and protect natural resources, Interstate Paper needed to find a way to develop environmentally friendly energy, maximize efficiencies and still produce a competitive product.


Interstate Paper has been improving their sustainable efforts for years. They’ve consistently reached past the “good enough” benchmark by constantly re-evaluating and adjusting their environmental focus and initiatives. These ongoing endeavors consist of maximizing current infrastructure and resources, investing in continuous improvements, and committing to future modifications.

Here’s a quick snapshot of successful initiatives toward safeguarding the environment:


  • Late 2003, Install Bubbling Fluidized Bed (BFB) Boiler

    - Provides 62% reduction in mill wide fossil fuel consumption
    - Supplies 45% of steam for mill
    - Utilizes a variety of non fossil fuels
    - Bark, wood waste
    - Green chips (pine plantation thinning)
    - Tire derived fuel (shredded discarded tires)
    - Sludge derived from recycling boxes / old corrugated containers (OCC)
    - Uses less than 10% fossil fuel for start-up, shutdown and stabilization

  • 2007, Upgrade BFB

    - Improves air system, fuel feed system and ash handling
    - Provides improved boiler efficiency
    - Reduces fossil fuel an additional 39% compared to the previous best in 2006

  • 2009, Upgrade Recovery Boiler Burner Management System

    - Improves boiler reliability
    - Provides 55% of the mill steam from black liquor (a tree by-product of producing pulp)
    - Uses less than 2% fossil fuel for start-up, shutdown and stabilization
    - Provides steam for the mill and recovers chemicals

  • 2010, Super Heater Replacement Project

    - Improves reliability
    - Initiate project in 2009 with 2010 Installation


  • Fossil fuel, 78% reduction since 2003
  • Water, 14% reduction (9 ½ million gallons of water a day from 11 million gallons a day
  • Electricity, 40% from biomass
  • Sulfur dioxide (a major contributor to acid rain), 60% reduction since 2003
  • Steam reduction
  • Particulates emission (tiny solid particles), 38% reduction due to:
    - Better BFB air pollution controls
    - Ability to run the mill without the Power Boiler

Being a privately owned paper mill provides the opportunity to focus on investments for long-term growth and to aggressively pursue environmental sustainability improvements. This is truly a biomass driven paper mill since 2003, with less than 14% fossil fuel used to make steam.
