Eco-Cycle innovates, implements, and advocates for local and global Zero Waste solutions to foster a more sustainable, regenerative, equitable and climate-resilient future. Our niche is in leadership—demonstrating what’s possible for Zero Waste in terms of policy, infrastructure, programs and culture change. We work in collaborative partnerships within every sector of the local community--residents, businesses, non-profits, schools, government-- to develop and prove Zero Waste solutions in Boulder County. We then disseminate that model by establishing Zero Waste leadership in other communities, and providing them with the organizing and communications tools needed to replicate our Zero Waste success as quickly as possible. Eco-Cycle is one of the largest non-profit recyclers in the USA and was established in 1976 by everyday residents who had a passionate belief in conserving our natural resources,, making Boulder one of the first 20 communities in the U.S. to offer curbside recycling. We continue to be driven by these same passions and innovative actions.
Founded in 1969, the Ecology Center is a nonprofit organization located in Berkeley, California that focuses on improving the health and the environmental impacts of urban residents. We address critical issues through a model of education, demonstration, replication, and advocacy. We envision a world where human activity nurtures the ecosystems that we all depend on — a world of sustainable cities; empowered, resilient communities; zero waste and zero toxics; equal access to healthy food; sustainable resource use; and a safe and stable climate.
Eureka Recycling is a 501(c)(3) nonprofit social enterprise based in the Twin Cities of Minnesota, with over 100 employees and $14 million per year in revenue. Eureka Recycling’s mission is to demonstrate that waste is preventable, not inevitable. Operating as a Zero-Waste Laboratory, Eureka is working to bridge the gap between our vision for a Zero Waste future and the realities of today with tangible, real-world solutions. We’re modelling that systematically addressing the way we manage our resources offers solutions to the most pressing issues of our time, including addressing the climate crisis, building strong local economies, and supporting healthy equitable communities. With key recycling contracts servicing the cities of Minneapolis and St. Paul, Eureka operates a collection fleet and 100,000 tons per year single stream MRF with a mission driven, triple-bottom-line focus that balances environmental, social and economic benefits. Examples include; living wages and paid time off for employees, city revenue sharing models, data transparency, composition studies, a focus on material quality and low residual rates, material marketing for highest and best use, education and technology. Our business units aim to advance the mission and demonstrate ways in which recycling can be an effective cornerstone of a truly regenerative economy that supports a shift towards source reduction and zero waste.
Founded in 1977, Recycle Ann Arbor (RAA) is nationally recognized as a leader in providing community-based recycling services. RAA started the nation’s fourth curbside recycling program in 1978, and RAA currently operates the state’s most comprehensive community drop-off station, a ReUse Center, curbside recycling program, Zero Waste special events programs, and a Construction and Demolition Material Recovery Yard. RAA provides living wage, union-represented jobs to over 45 FTE staff; has an annual operating budget of approximately $7.5 million; services a population of approximately 121,000 and 47,500 households; and has a geographic reach of approximately 100 square miles. RAA has been a contracting partner with the City of Ann Arbor for over 35 years. Additionally, Recycle Ann Arbor provides outreach and education services to all Ann Arbor residents and businesses who currently have curbside recycling or who want to further explore waste diversion solutions.

Michael Garfield has worked for health, environment, and justice in Michigan for over 30 years, and has served as Executive Director of the Ecology Center since 1993. He’s been one of Michigan’s leading voices on environmental issues, and an architect of some of the state’s most ambitious municipal initiatives in land use, transit, and solid waste.

Under his leadership, the Ecology Center has grown from a primarily local organization focused on Washtenaw County into a regional innovation center with a national reputation. Over the past two decades, the Ecology Center spearheaded a statewide campaign that closed all of Michigan’s medical waste incinerators, established the Midwest’s largest locally funded land preservation program, created the country’s premier consumer product toxic testing service, and won the nation’s Top Community Recycler award. The Ecology Center has offices and facilities in Ann Arbor and Detroit, and is the parent organization of Recycle Ann Arbor.

Garfield’s advocacy work has specialized in environmental health, climate, zero waste, and land use policy. He was one of the principal architects of Ann Arbor's nationally regarded recycling program, leading campaigns that funded major public investments in the program’s infrastructure. Between 1999 and 2005, he led or co-led six successful ballot campaigns that are preserving over 10,000 acres of land in southeast Michigan, including campaigns that created the Washtenaw County Natural Areas Program, and the Ann Arbor Parks and Greenbelt Program. He was one of the leaders of the 2014 ballot campaign to expand transit service in Washtenaw County. He’s testified before congressional, state legislative, and local committees, and served on numerous nonprofit and public boards and commissions.
