Our Circular Economy Research Assistants are currently supporting the organization's work on sustainable waste management across four key streams: textile, organic, electronic, and construction & demolition waste. In this role, they are meeting with industry leaders to gather insights, visiting active work sites to observe processes firsthand, and conducting individual research projects tracing the full lifecycle of each waste stream. Alongside this work, they are completing their True Advisor Credentials, developing the expertise needed to advise on circular economy practices.
This work is made possible through the generous support of the Pinkerton Foundation, PENCIL Inc., the Hyde & Watson Foundation, and the North American Association of Environmental Education.
