Building a Circular Bioeconomy Ecosystem in Wisconsin (Madison)

This is one of two workshops next in a series exploring the development of a circular bioeconomy ecosystem in which renewable and waste resources are used as raw materials, substituting biomass-based and recycled carbon for fossil carbon in energy and products. Developing these bio-based production chains and businesses could create jobs, help decarbonize Wisconsin industries, and promote statewide rural economic development. Renewable Natural Gas, Carbon Management, and Sustainable Aviation Fuels and Biobased Chemicals will be discussed.

Workshops on Renewable Natural Gas, Carbon Management, and Sustainable Aviation Fuels and Biobased Chemicals have been held so far. Gaps and opportunities in each of these areas of the bioeconomy have been identified set the stage for future discussions regarding how to advance the bioeconomy in Wisconsin.

Join us in-person on either Thursday, May 25 in Madison or Wednesday, June 21 in Appleton to review and prioritize recommendations for these major areas of Wisconsin’s bioeconomy, connect with other stakeholders, and discuss ongoing strategies to build a bioeconomy ecosystem, including a possible membership organization. There is no cost to attend and breakfast and lunch will be provided.
