In Pursuit of Polystyrene: Preventing Polystyrene Foam Pollution in Lake Ontario

On Tuesday November 18, 2025 from 1:00-2:00pm EST,  PPG will be hosting a webinar in partnership with the University of Toronto Trash Team, a collaborator of the Toronto Inner Harbour Floatables Strategy. In Pursuit of Polystyrene: Preventing Polystyrene Foam Pollution in Lake Ontario is a multi-phase Pollution Prevention Project led by the University of Toronto Trash Team focused on addressing polystyrene foam pollution at its source. Key findings from the project will be presented, which explores the problem and assesses levels of awareness regarding foam insulation and other construction materials leaking into our local environment. A project conducted in collaboration with local construction companies will also be discussed, testing the effectiveness and feasibility of practical solutions on-site to reduce plastic pollution. 

This work was done in collaboration with Partners in Project Green (a program of Toronto Pearson and Toronto and Region Conservation Authority) and the Ontario Ministry of the Environment, Parks and Conservation, and contributes to the Toronto Inner Harbour Floatables Strategy.
