In its own words
What could break it.
Commodity & input dependence
- wood fiber, natural gas, pulping chemicalsmedium
Fiber (virgin wood + recycled) is the largest raw-material cost for containerboard; mills also consume purchased natural gas (26% of fuel) and chemicals (starch, calcium carbonate, caustic soda, sodium chlorate), exposing PCA to input-price inflation.
“Fiber is the largest raw material cost to manufacture containerboard. We consume both virgin wood fiber and recycled fiber in our containerboard mills, and all of our fiber comes from renewable resources.”

Regulatory & policy
- EPA Pulp MACT / NESHAP residual-risk reviewmedium
EPA is revising Pulp MACT/NESHAP standards for chemical-recovery combustion sources; PCA was one of seven companies required to respond to an EPA questionnaire, with pollutant testing at five PCA mills scheduled to begin Spring 2026, potentially raising compliance costs ($64M spent in 2025).
“In November 2024, PCA was one of seven companies selected by EPA to respond to a questionnaire about operations and equipment to support EPA's requirement to revise existing Pulp MACT standards. As part of the questionnaire, EPA is requiring companies, including PCA, to undertake pollutant testing scheduled to begin Spring 2026. Five of PCA's mills will participate in the risk assessment.”
