This research was conducted by RRS on behalf of the Materials Recovery for the Future (MRFF) project, a collaborative project hosted and managed by The Foundation for Chemistry Research and Initiatives at the American Chemistry Council (ACC). We gratefully acknowledge Emily Tipaldo for her assistance in managing this project and Jeff Wooster, MRFF Steering Committee Chairperson for his leadership. We also appreciate the hard work of the consumer packaged goods companies, resin producers, manufacturers, and trade association representatives who contributed materials, technical expertise, and even extra labor in waste sorts.
