Carbon Capture Study (CONT’D FROM PAGE 16)
used to make paper can be used as biogenic fuel. Feeling Salty A saline aquifer is a geological formation made of po- rous rocks and brine — water that is too salty to be used for agriculture or drinking — deep below the earth’s sur- face. Pressurized CO2 can be injected into saline aquifers, according to the Massachusetts Institute of Technology. There, the CO2 could dissolve over time, react with the minerals in the aquifer or become trapped in rocks’ pores. PCA identified four of its mills that are located on or near saline aquifers that can be used to permanently store the carbon dioxide they produce: Counce, Tennessee; De- Ridder, Louisiana; Jackson, Alabama; and Valdosta, Geor- gia. These mills emitted a combined 4.5 million metric tons of biogenic CO2 during the 2021 baseline year.

The company explored multiple technologies before landing on an amine-based solvent approach that involves capturing CO2 from post-combustion flue gas emissions from a biogenic boiler at the mill. PCA received the test unit in pieces that were delivered in 12 shipping contain- ers, and after an eight-week build it stood 15-stories tall. What's Next Now, PCA is working on its seven- to nine-month engi- neering and design study for a possible large-scale CCS facility; it’s slated for completion in early 2026. While PCA’s longer-term plans involve expanding CCS to multiple sites, it acknowledges in the sustainability re- port that there are risks to pursuing this: technologies do not always advance or become commercialized on ex- pected timelines, and it might not be able to incorporate the technologies in an efficient or cost-effective manner. Even so, the company is “looking for opportunities to integrate the system more efficiently within our existing mill operations — particularly around heat recovery and energy optimization. Of course, financial viability will be key, as these systems require significant investment,” Lit- zenberg said. PCA indicated in its most recent report to the Task Force on Climate-Related Financial Disclosures that it stands to receive tax credits for CCS projects of up to $85 per metric ton, which makes the project financially viable. Reducing tax incentives beyond that amount could slow the rate of technology deployment or make such projects unviable. Visit packagingcorp.com for more information.
