Food Residue Study 2022
A food residue study was conducted in November 2022 to learn whether foodservice packaging (such as take-out containers, cups or pizza boxes) set out for recycling were more contaminated than food contact packaging (such as peanut butter jars, cans or pasta boxes) that has traditionally been accepted at single-stream material recovery facilities (MRFs). This study served as a follow-up to two previous studies conducted in September/October 2013 and July 2014.
