The scope of our work is on the bioeconomy—the economic sector that produces and supplies food, feed, and fiber and biomanufactures other products from agriculture, forestry, and aquaculture. 

The goal of the Circular Bioeconomy Systems Institute (CBSI) is to create a more sustainable, resilient, and environmentally friendly bioeconomy sector that not only produces and supplies food and other bioproducts but also regenerates natural resources, minimizes losses and wastes, and mitigates the environmental impacts of bioproduct supply chains. It represents a shift away from the linear "take-make-dispose" model to a more circular and restorative approach.

CBSI embraces collaboration and participation across expertise and disciplines. The Institute is open to ASABE members and non-members of other professional societies and stakeholders.

I invite you to join in our effort to develop innovative solutions that lead to a more circular bioeconomy.

NIST to Host Workshop on Food Waste

Virtual Event
December 5–7, 2023

NIST Workshop on Food Waste NIST, the National Institute on Standards and Technology, is hosting a workshop to deterine how the agency can serve the food and organic waste community in their efforts to reduce and repurpose the waste.

NIST's Circular Economy Program is supporting the nation’s transition from a linear economic model to a cyclical one, where the materials we mine/farm/extract from the environment remain in the economy as long as feasibly possible and are not discarded after use.

Topics for the free workshop may include:

  • Current and Emerging Technology
  • Characterization & Contamination
  • Data, Measurement, and Modeling
  • Legal and Regulatory Barriers and Opportunities

Join a CBS Working Group

How can you be a part of this important initiative? Stay up-to-date with news and conversation by joining the mailing list.

We also invite you to join one of the the three working groups. Review their charges, below, to find the group that best fits your interests, then contact the group lead for more information.

Task Force Leader: Jim Jones

Working Group 1
Contact: Joe Sagues
Create messaging materials and documents (including PowerPoint presentations) with succinct information to educate, engage, and recruit ASABE members, students, and leaders of public-private sectors who will contribute to the CBS initiative to build a more circular bioeconomy.

Working Group 2
Contact: Sue Nokes
Develop engaging activities and mechanisms within ASABE that advance CBS and for building circular bioeconomy systems

Working Group 3
Contact: Brahm Verma
Draft a plan, by considering inputs of a stakeholder engagement group, for connecting and bringing together professional societies into an alliance that includes collaborative mechanisms (activities, programs, projects and services) and features to develop convergent science and engineering knowledge to transform systems that underpin a new circular bioeconomy.

Introduction to Circular Bioeconomy Systems

Learn about the initiative, and about the principles behind circular bioeconomy systems.

NAE Focus on Complex Unifiable Systems

NAE Logo

ASABE Fellows James Jones, R. Paul Singh, Sue Nokes, and Brahm Verma, as well as ASABE member Bruno Basso, are among the presenters and moderators for the Virtual Forum on Complex Food and Agricultural Systems: Engineering for Sustainability and Resilience, hosted by the National Academy of Engineering.

The forum will review characteristics and challenges of existing systems and the need for various engineering disciplines to converge to lead the transformation of current mostly linear food and agriculture into circular and resilient systems. The forum will also explore needed progress and investment in education, R&D, modeling and analytics, public-private collaboration, and other dimensions.

The forum will take place September 9, from 11 am to 4 pm (eastern time). Registration is free.

ASABE is proud to be a major sponsor for this event.
