TAPPICon 2025, organized by the Technical Association of the Pulp & Paper Industry, returns as an in-person event 9-12 March at the Georgia World Congress Center in Atlanta. Designed for mill managers, process engineers, R&D directors, suppliers, and sustainability officers across pulp, paper, tissue, packaging, and converting, the conference delivers more than 100 technical sessions, 12 peer-reviewed short courses, and a 200-booth exhibition. The 2025 program is built around six tracks: Papermaking, Tissue, Packaging & Specialty, Energy & Sustainability, Digitalization & Automation, and Workforce Development. Keynote speakers include IKEA’s chief sustainability officer who will outline the retailer’s 2030 fiber-sourcing roadmap, and Procter & Gamble’s VP of R&D for paper who will share consumer-driven innovation strategies. Daily plenaries explore decarbonization funding available under the U.S. Inflation Reduction Act, the EU’s forthcoming packaging regulation, and AI applications for predictive maintenance. Technical highlights feature mill case studies on retrofitting existing machines to produce lightweight containerboard, closed-loop water systems that reduce fresh-water intake 40%, and pilot data on enzymatic refining that cuts energy demand 8%. A new “Net-Zero Mill” spotlight session gathers suppliers offering heat-pump drying, green-hydrogen burners, and carbon-capture integration. The Tissue Track focuses on through-air-dried energy optimization, while the Packaging Track dissects fiber-based barrier coatings as an alternative to PFAS. Hands-on workshops cover fundamentals of paper machine clothing, wet-end chemistry control, and safe handling of nanocellulose. Networking events include the Welcome Reception in the exhibit hall, the annual inventors’ breakfast honoring 25 new U.S. patents, and mill tours to a nearby 100% recycled linerboard facility. A career center matches students from nine North American universities with recruiters, and a 24-hour “hackathon” challenges teams to reduce broke waste using supplied mill data. TAPPICon 2025 offers 16 professional development hours for licensed engineers and publishes proceedings open-access after the event.
