QR Codes Show Promise In Reducing Food Waste
What’s more, consumer are more likely than not to feel that QR codes help with decision-making processes, says Forrester Research, which found in its 2022 study that 61% of U.S. online adults who have used a QR code agree that QR codes on product labels offer excellent depth of information. More than half (55%) said they scan QR codes on products in stores to help them make purchase decisions, and just 29% of consumers who use them reported being often disappointed with the content after they scanned a code.
Looking ahead, the Cornell study researchers noted the QR codes have the potential to communicate with smart refrigerators to inform consumers when they need fresh milk, as well as suggest recipes using ingredients that are nearing the end of their shelf life — combing for a new digital food system infrastructure to reduce food waste.
Dairy products are among the top three food groups with the largest share of wasted food in the United States, according to Samantha Lau, the Cornell doctoral student in food science who conducted the study, with fluid milk accounting for 65% of dairy product food waste because of consumer confusion about when to discard products. This in turn results in nearly $6.4 billion in losses annually, she reported in a related study.

Consumer goods companies are exploring their use across a range of use cases, drawn by both the promise of consumer engagement and an ability to collect valuable first-party data. Mondelēz International, for example, leveraged them in two different food traceability pilots last year. One provided detailed ingredient origin information to U.S. consumers who scanned the code on a Triscuit box, while another in France also leveraged used blockchain technology to trace the journey of Harmony wheat from the field to shelf.
Campbell Soup Company, meanwhile, partnered with Universal Music Group to create curated playlists of newly recorded music with specially marked soup cans — executed as part of larger efforts to modernize the Campbell’s brand.
While Forrester reports that consumers find QR codes to be most helpful for redeeming coupons and promotions while shopping, making smart purchase decisions in a grocery store is the second most-cited choice.
