U of T Trash Team

Increasing Waste Literacy to Fight Plastic Pollution

Unless someone like you cares a whole awful lot, nothing is going to get better. It’s not.”
Dr. Seuss, The Lorax

Who we Are

The U of T Trash Team is a science-based community outreach group made up of undergraduate and graduate students, postdocs, researchers, local volunteers and staff all working together with a common goal to increase waste literacy in our community while reducing plastic pollution in our ecosystems. We were founded in 2017 in collaboration with the Rochman Lab, part of the Department of Ecology and Evolutionary Biology at the University of Toronto.

Our Mission

We aim to connect people and increase literacy concerning material consumption and waste with fun, creative and practical actions. We use education, public outreach and scientific research to deliver evidence-based solutions to decrease solid waste and promote a circular economy.

Our Vision

We envision a fun and engaged waste-literate community actively working to protect people, wildlife and the planet through the intersection of science, policy, community engagement and innovation that promote waste reduction.

Our Values

We are team-oriented, collaborative, fun, creative, positive, inclusive, respectful, supportive and non-judgmental.

In our community, everyone is treated as an equal and with respect.

How we Work

Our local projects use research to inform policy and management, and education and community outreach to increase waste literacy, engage the public and implement effective solutions. 

Solutions-based Research

Data-driven projects to help inform solutions.


Elementary classroom programs and ongoing public education, for all ages.

Community Outreach

A range of programs including cleanups and presentations throughout the year.

Founding Members and Program Leads

Chelsea Rochman
Head of Operations and the Program Lead of Scientific Programming and Application

Chelsea has been researching the sources, sinks and ecological implications of plastic debris for more than a decade. In addition to research, Chelsea works to translate science beyond academia. For example, she presented her work to the United Nations General Assembly and at the US State Department. Moreover, she has served as an expert witness for both the Canadian and United States government.

Susan Debreceni
Program Lead of Volunteer Engagement and Community Programs

Susan received her BSc in Zoology with a minor in Psychology from the University of Guelph and a certificate of Ecosystem Management Technology through Fleming College. She also received a certificate in the Fundamentals of Volunteer Management through Humber College. She is passionate about connecting individuals with meaningful opportunities and spent over a decade supporting a national network of community volunteers through the Great Canadian Shoreline Cleanup

Rafaela Gutierrez
Program Lead of Social Science and Educational Programs

Rafaela received her PhD in Science and Technology Policy from the Institute of Geosciences, UNICAMP, Brazil. Rafaela Gutierrez is a social scientist with expertise in waste policy. She has a keen interest in up- and downstream processes for plastic recycling. Over the past decade, she has studied, advocated and worked with low-income communities in Brazil focusing on how to improve the socio-productive integration of waste pickers into formal recycling streams.


Cassandra Sherlock
Community Outreach and Research Specialist

Cassandra received her Honours BSc from U of T in Spring 2020, specializing in Ecology and Evolutionary Biology. During undergraduate, she was a Research Assistant in the Rochman Lab, assisting with projects and leading her own honours thesis project investigating microplastics in tree swallow nestlings. Cassandra focuses on our Solutions-based Research programs, specifically Fighting Floatables in the Toronto Harbour and the Great Lakes Plastic Cleanup.

Our Volunteers

With a small support staff, our volunteers fuel the organization with new ideas, positive energy, passion and talent. They are empowered to co-create meaningful experiences and programs on waste literacy. Our team is made up of undergraduate and graduate students, postdocs, early-career researchers, and members from outside the U of T community. These volunteers are predominantly young adults, gaining experience and expertise to be the next leaders in our environmental movement.
