Milestone Study on Paper Waste Management in the US and Canada — Full Report

November 18, 2024 143 pages Sustainable Living and Economies

The CEC has commissioned this series of three milestone studies as part of its “Transforming Recycling and Solid Waste Management in North America” project, with the goal of supporting Canada, Mexico and the United States in their efforts to promote circular economy and sustainable materials management approaches to encourage eco-design and increase product and material reuse, recovery and recycling rates.

These studies aim for better understanding of the opportunities in the recycling sector and secondary material markets for plastics, paper and bioplastics waste. These studies focus on Canada and the United States, and a separate set of studies focused on Mexico will be available in the coming months. Building on the results of these milestone studies and on input by key actors, a joint pilot project is currently underway in Canada and the United States with the purpose of assessing the feasibility of innovative technologies, policies and practices that can be adopted at scale across North America.

The complete report is available in English only, but you can consult the executive summary in English, Spanish, and French.
