The City of Tacoma Environmental Services Department’s Solid Waste Management Division, in partnership with Prairie Robotics, is launching a two-year pilot project to help reduce contamination in the residential recycling stream. Funded by a $1.8 million grant from the Environmental Protection Agency’s Recycling Education and Outreach Grant Program, the project aims to educate residents about what can and cannot be recycled in Tacoma’s curbside program.
The pilot will use smart camera technology to detect contamination in residential recycling as it is collected. When contamination is identified, residents will receive educational postcards highlighting which items are not accepted in Tacoma’s curbside recycling system.
“Contamination impacts how we can deliver services and the cost of those services for all residents,” said Solid Waste Management Division Manager Lewis Griffith. “Educating residents on what is accepted in our curbside program, and reducing contamination, can have positive impacts on the program for all residents of Tacoma.”
Prairie Robotics, a Canadian software development and engineering firm, was selected to support the project. Their artificial intelligence-powered platform is already in use with waste providers and municipalities across the U.S. and Canada, including Waste Connections, GFL, and the cities of Greensboro, N.C., and East Lansing, Mich. The system provides real-time feedback to residents, helping them recycle more accurately.
“We are thrilled to partner with the City of Tacoma on this project and believe that our platform can help to reduce contamination in recycling across Tacoma,” said Prairie Robotics CEO Sam Dietrich. “We look forward to continuing to work with the City as this pilot evolves to ensure that our services meet the need of Tacoma residents.”
The pilot will roll out to residential recycling routes in phases over the next year. Residents in selected areas will begin receiving postcards starting this month. As this is an educational initiative, no fees or penalties will be issued for contamination identified during the pilot. The project will continue through the life of the grant and is expected to be reviewed in June 2027.
