The linear economy serves as the basis for how the majority of our products are designed and manufactured today. Yet, this “take, make, waste” approach to production and consumption is the driver of many of the ecological crises we face: climate change, pollution, and biodiversity loss. Circularity, also known as the circular economy, offers an alternative framework to eliminate waste and pollution, keep products and materials in use, and regenerate nature. Supply chain disruptions during the COVID-19 pandemic pushed many businesses to consider circular economy principles as a means to improve supply chain resiliency. More recently, uncertainty around global trade agreements has had a similar effect. 

This discussion will dive deep into the circular economy. We’ll learn about real-world examples of how circular economy principles are being put into practice; look at the market and geopolitical trends spurring circular thinking; understand what factors decision-makers are weighing when incorporating circularity into their value chains; and look at how policymakers, at both the global and local levels, are incentivizing circular practices. 

This panel is co-hosted in collaboration with The Carbonauts and Idealist, and will feature the following experts:

  • Danielle Holly, Executive Lead for North America, Ellen MacArthur Foundation
  • Samantha Wittchen, Co-founder,  iSpring and Circular Cities Network
  • Katie Durham, Co-founder & CEO, Supra Elemental Recovery, Inc.
  • Moderated by Mikaela Ringquist, NY Chapter Lead, Women in Cleantech & Sustainability
