CBS Day and More
at the 2023 ASABE Annual International Meeting

Join Us
Plan to attend the ASABE 2023 annual meeting, July 9-12, in Omaha, Nebraska, for a variety of events that will advance ASABE's CBS initiative:
  • Plenary sessions with invited speakers
  • Roundtable discussions
  • Technical and poster sessions
  • Social hour
  • Technical tour
Mark your calendar for the July 9 program and other events. We encourage your participation and welcome your contributions to the dialogue.
Submit an Abstract 
We encourage your abstract proposals as we explore ways of addressing the multiple challenges of transitioning to circular bioeconomy systems.
What to Expect
  • Informative events around the cross-cutting concepts and solutions for circular bioeconomy systems
  • Increased awareness and participation in CBS activities by scientists and engineers internal and external to ASABE
  • A defined action agenda for the CBS initiative, working with partners, to support transformations to circular bioeconomy systems

Calls for Abstracts

CBS Logo CircleAfternoon Concurrent Sessions

Education and professional development materials for circular bioeconomy systems
Jointly sponsored by ASE-16
Educational material, courses, and interdisciplinary experiences for undergraduate, graduate, and post-graduate levels. What are the needs and opportunities? What educational resources currently exist that teach CBS principles and approaches? What educational resources are envisioned and what is the target audience? How can these be included in design classes? What approaches can be used to give students experience in interdisciplinary teams? Who might develop needed materials?

Advancing metrics, sensor systems, and standards for circular bioeconomy systems
What capabilities currently exist regarding sensing variables important for CBS? What is needed and for what purposes? What methodologies are available to quantify CBS and contrast among alternative designs? What is the status of standards that might benefit CBS and lead to more widespread adoption?

Integrating social and policy issues in developing circular bioeconomy systems
What changes are needed to enable implementation and acceptance of solutions that lead to a more circular bioeconomy? What approaches are used to characterize economic and social impacts of current and more circular systems? What scales of analysis are appropriate and for what purposes (e.g., farmers, businesses, policy makers)? How can socioeconomic benefits and tradeoffs be assessed as they interact with environmental and natural resources goals?

Testbeds for innovating, evaluating, and demonstrating CBS technologies and systems
How can Farms of the Future, infrastructure for processing food and other biomass products, controlled environment production systems, etc. be used in research, evaluation, and demonstration of alternative circular bioeconomy systems? What existing testbeds could be used to advance CBS development, evaluation, and demonstration? Are more needed to address the various constituent systems involved in CBS?

Advances in analytical methods for circular bioeconomy systems across value chains
Topics of interest could include life cycle assessment, techno-economic analysis, process modeling, digital twin development and use, artificial intelligence, analysis of tradeoffs among goals for circular bioeconomy systems, scaling methods for assessing circularity at different spatial scales, and integrating different methods to address CBS questions across value chains or constituent systems.

Synthetic biology innovations contributing to CBS
Presentations could be on innovative processes for producing bioproducts that are shown to increase circularity in bioeconomy systems, including biotechnology targeting plant or animal production or processing, changing the soil microbiome or improving soil health, or developing new biomass-based materials.

Characterizing circularity of entire bioproduct value chains
Presentations can include existing and future alternatives in value chains aimed at increasing circularity. Systems and approaches for closing the cycles of key resources across value chains. Challenges and opportunities for increasing circularity of value chains.

Enhancing bioeconomy circularity through technology and design across value chains
This could include papers submitted from any community that demonstrates use of CBS principles in increasing circularity in these selected systems.

Technology and methodology advances for more sustainable circular bioeconomy systems
Abstracts for posters are requested for any constituent systems of production, processing, packaging, and supply of bioproducts, entire value chains, and waste recovery and use, including examples that describe work completed or analyses of proposed systems that would increase circularity relative to existing systems.
