In an era when artificial intelligence is rapidly reshaping industries across the globe, Walmart, a titan in the retail world, is not merely adopting new technologies—it is actively forging a new path. This is not just about incremental improvements; it is a profound digital transformation on a large scale, impacting everything from back-of-store operations to the very freshness of the produce nestled in your shopping cart. The vision is clear: leverage cutting-edge AI to enhance efficiency, empower workers, and ultimately deliver a superior customer experience, proving that the future of retail has arrived, and it is smarter than ever before.
One of the most compelling narratives in Walmart’s AI journey addresses a challenge that has plagued retailers for generations: perishable goods. Stores like Walmart and Costco have long grappled with the disheartening sight of “humongous quantities of food, clothes, beverages, and other items rotting in front of their eyes.” This not only results in significant financial losses for warehouses and stores but also represents a staggering amount of waste. Walmart, however, is tackling this head-on with an ingenious, AI-driven solution.
The core of this innovation lies in new AI-driven scanners designed to provide store employees with real-time, actionable insights into product conditions, especially for sensitive items like fruits. Imagine a device that instantly informs associates when fruits, such as bananas, are on the verge of spoiling, prompting them to sell them before they rot. This precision extends beyond the produce aisle; the technology also advises workers on the optimal time to initiate apparel sales, a critical capability given the sudden shifts in fashion trends.

This revolutionary AI tool eliminates the guesswork in crucial decisions for associates. As Swati Kirti, Senior Director of Data Science at Walmart International Tech, eloquently puts it, “This AI tool essentially assists associates in offloading the decision – making process and enables them to know precisely what to do with that product at that specific time.” Beyond indicating ripeness or fashion urgency, the device also offers recommendations on whether products require a price adjustment or even a complete replacement due to deteriorating quality, and it issues warnings if items need to be returned to the vendor. All this is accomplished through a specialized scanner that effortlessly captures and processes relevant details from each item.
The potential impact on waste reduction is monumental. Consider the fashion industry: if AI can conduct mid – season quality checks on clothing, the enormous problem of cloth wastage can be dramatically reduced, which directly translates into significant cost savings. Walmart’s versatile scanner is designed to be applied across all store items, making it a comprehensive waste management solution. Currently in its testing phase, this AI – driven program is set to undergo trials in Canada, with aspirations for a broader international rollout.
The statistics underscore the urgency of such innovations. Recycle Track Systems reports that the U.S. alone discards approximately 60 million tons of food annually, accounting for about 40% of the nation’s total food supply. Walmart’s own data reveals a substantial contribution to this issue, with the company wasting around 3.5 million tons of food in 2018 alone. The strategic importance of this new tool is championed by Sravana Karnati, Senior VP and CTO for Walmart International Technology, Walmart Global Tech, who states, “Using tools like our AI – powered waste management system helps reduce our environmental footprint, requiring fewer societal resources and, at the same time, helping to reduce our own operating costs.”
