This week, Trellis Group brings its annual circular economy conference to Denver. At Circularity 25, leaders from corporations, startups and nonprofits will explore ways of doing business at scale that eliminates waste from the equation, starting with product design.
“The circular economy requires a fundamental change to business, not just incremental steps or bolt-ons,” said Trellis Circular Economy Director Kori Goldberg.
The event is built to provide pragmatic knowledge and practical tools for circularity practitioners. (I’ll definitely check out the sheets of fungus-based “leather” dripping from the ceiling of the bar at the “carbon positive” Populus Hotel, near the event at the Colorado Convention Center.)
The full program is here. Below are key moments to watch, according to members of the Trellis editorial team and event organizers.
