Anna Sacks - who goes by the name 'thetrashwalker' on Instagram and TikTok - has been recording her 'trash walks,' where she roams Manhattan's streets and sifts through garbage bags, since 2018. Some of the videos show mountains of garbage bags full of unopened food and sealed disposable products from places like Party City that can still be eaten or used. In the video, she found full garbage bags of unopened M&Ms, Lindt chocolates, heath bars and other candies. Much of Sacks’s videos focus on waste from major corporations like CVS, Party City and Starbucks, but she's rummaged through residential and schools' waste in in the Upper West Side of New York City.
