Seattle Circular Marketplace


To help advance Seattle’s transition from an extractive linear economy to a more regenerative, global circular economy with zero waste, thriving industries, and healthy communities.


In 2020, the Port of Seattle awarded the nonprofit organization, Seattle Good Business Network (and its program Seattle Made that supports over 600 urban manufacturers), a seed grant to develop and pilot such an online platform to facilitate business-to-business material transactions of various “waste” products that could be used as material inputs for other end markets. Over a period of nine months, working with a Steering Committee comprised of public and private-sector stakeholders,1  and facilitated by Circular by Design, we have established a beta platform, tracked and facilitated materials exchanged, and identified partners and program elements essential to larger-scale efficiencies that would offer a boon to regional economic development, solve persistent material ‘waste’ stream problems, and help meet our regional equity and climate goals. 


Over the course of this development period, the Committee determined that pursuing a partnership with the United States Business Council for Sustainable Development would accelerate our progress towards a highly functional and scalable online marketplace, which would anchor an ecosystem to include wrap-around advisory services and offline materials-exchange facilitation.

Goals & Objectives

  • Understand and track material flows to help prevent material consumption and waste production
  • Reduce and track GHG emission rates
  • Reduce regional waste streams by facilitating end-market solutions 
  • Identify additional pathways towards equitable economic and workforce development
  • Support organizations, businesses, and emerging entrepreneurs that would like to transition to circular business models.
  • Create distributed and resilient material supply chains for our region

Get Involved!

This work is currently being supported by a dedicated steering committee of 11+ industry stakeholders and public and private partners who help inform and contribute to our strategy and processes of the development and scaling the Seattle Circular Marketplace. This platform is inspired by our collective vision for a global circular economy with zero waste, thriving industries, and healthy communities.
