Building Circular Supply Chains: Turning By-Products into Value

​How can waste streams become valuable resources? This interactive workshop brings together innovators from the fields of biogenic CO₂ recovery, bio-based packaging, and fermentation biomass waste valorization to explore practical approaches for building circular value chains. Through real-world examples, participants will discover how by-products from agriculture, food processing and fermentation can be transformed into high-value products and services, including renewable CO₂, sustainable packaging materials, and future functional ingredients. The session will highlight the technological, economic, and collaborative conditions required to scale circular solutions and accelerate the transition towards aregenerative and circular bioeconomy.
