UMass Amherst Dining Services piloted AI-driven robots that use cameras and computer vision to automatically identify and sort recyclables from general waste. The technology, developed by UMass engineering alumni, lets a single waste bin receive all materials and then sorts them automatically — removing the burden from individual users to sort correctly.

Details

The pilot deployed technology from rStream, a startup founded by UMass Amherst College of Engineering graduates Ethan Walko and Ian Goodine. The robots use computer vision — a form of AI that allows machines to interpret and understand images — to identify materials in a waste stream in real time and route them to the correct processing category. The company secured a $275,000 NSF Small Business Innovation Research (SBIR) grant and $125,000 from the Massachusetts Clean Energy Center's AmplifyMass program to develop and deploy the technology. This represents a campus operational deployment of AI rather than research alone.

Other practices by University of Massachusetts Amherst

OtherUMass Amherst runs a central "AI at UMass" website and a series of cross-campus working groups that coordinate AI research, teach faculty about AI tools, and develop ethical guidelines for how AI should be used at the university. These groups span the arts, computer science, social sciences, and public interest technology.OtherUMass Amherst established a formal university policy on the use of generative AI in academic work. The default rule is that using AI to do your academic work for you counts as cheating — unless the instructor of a specific course explicitly says otherwise. The policy took effect Fall 2025 and was developed by a faculty task force that studied the issue throughout 2023–2024.Customer SvcUMass Amherst computer science students built AI-powered tools for Massachusetts state agencies that help members of the public access government services more easily. Projects completed in 2024–2025 include an AI assistant to help people apply for environmental permits, a caller-routing tool for unemployment assistance, and an HR chatbot for a state technology office.
