RBI’s Annual Workshop Fosters Collaboration, Innovation for Pulp and Paper Manufacturing
Primary tabs
The Renewable Bioproducts Institute (RBI) 2025 Spring Workshop, held May 12–13, brought together leading researchers, industry professionals and students to explore innovations in pulp and paper manufacturing. Hosted at the Kendeda Building and the Paper Tricentennial Building, the event opened with remarks from Carson Meredith, RBI executive director, and featured presentations on energy and resource efficiency, carbon accounting and competitiveness.
Highlights included talks on membrane separations, electrochemical processing and low-carbon fuels, with contributions from experts such as Chris Luettgen, Jose Gonzalez, Sankar Nair, Marta Hatzell and Dave Beck.
Insights from the 2025 RBI Spring Workshop
- Revolutionizing Kraft Pulping with Graphene Oxide Membranes
Georgia Tech’s rGO membrane technology is transforming the kraft pulping process. These membranes enable efficient black liquor dewatering, organic acid recovery and lignin fractionation—leading to significant energy savings, water recycling and new revenue streams from bioproducts. - North America’s Dual Challenge: High Emissions, High Opportunity
While North America remains a pulp and paper powerhouse (15% of global capacity), it also has one of the highest carbon intensities. This presents both a challenge and an opportunity to lead in emissions reduction through asset renewal and innovation. - Biogenic CO₂: From Emission to Asset
Kraft pulp mills emit large volumes of biogenic CO₂—an untapped resource. With carbon capture and utilization (CCUS), mills could generate up to $300 million annually in carbon removal credits, turning emissions into economic value. - Integrated Biorefineries: The Future of Pulp Mills
The vision for pulp mills is evolving—from single-product facilities to multi-product biorefineries. Innovations like lignin-based materials, organic acid conversion to biofuels and advanced nanofiltration are paving the way for circular use of carbon in manufacturing. - Decarbonization Is a Strategic Imperative
With increasing regulatory and consumer pressure, especially from global brands targeting Scope 3 emissions, pulp and paper producers must act. Embracing technologies like rGO membranes and CCUS is not just sustainable—it’s essential for competitiveness. - Electrochemical Carbon Capture and Conversion for On-Site Fuel Production
Hatzell’s lab is pioneering the use of bipolar membrane (BPM) electrolysis to convert captured carbon (from bicarbonate solutions) into valuable fuels like CO and H₂. This approach enables:- 100% carbon utilization with more than 70% Faradaic efficiency for CO production.
- Integration with pulp and paper processes to valorize CO₂ emissions instead of storing them.
- Use of acid-stable single-atom nickel catalysts to improve selectivity and efficiency.
- The PAPER-ZERO Initiative
This initiative explores transformative pathways to decarbonize the pulp and paper industry by:- Evaluating scenarios that eliminate combustion of black liquor and waste wood.
- Investigating renewable energy integration and alternative uses for black liquor.
- Assessing the cost, energy and environmental trade-offs of emerging technologies.
The workshop also featured a student poster session, networking opportunities and updates on APPTI collaborative projects. The event concluded with a meeting of the RBI Industry Advisory Board, reinforcing the institute’s role as a hub for partnership and innovation in renewable bioproducts.
“We’re grateful to our industry member partners for sharing their time and expertise,” said Belinda Vogel, research engagement manager. “The advisory board meeting highlighted how essential collaboration is in advancing basic science and renewable bioproduct manufacturing.”
