Interstate Resources has published a series of PDF files about the U.S.corrugated manufacturing group's sustainability efforts. Download this story at www.interstateresources.com/PDF/Interstate-Resources-Reduction-for-Fossil-Fuels.pdf.
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.
