Walmart recently announced an intelligent quality management system is being used throughout Walmart supply chains and distribution centers to reduce waste and increase quality of fresh produce.
The quality management system, called Eden, utilizes machine learning and temperature monitors to predict the freshness (ie. shelf life) of a variety of commodities, ranging from bananas to apples to tomatoes. Eden aims to track freshness throughout the supply chain, which empowers informed decision making based upon the remaining freshness of a shipment of product. Making supply chain decisions based upon the freshness allows for optimal routing and rotation of fresh produce, which in turn will reduce waste and increase quality, which is win for all stakeholders.
For example, if Eden sees that the temperature on a pallet of bananas has increased beyond an optimal threshold, the smart system can judge that the quality has degraded, and re-route that shipment to a closer distribution center or store.
The proliferation of technology to fight food waste (and increase the bottom line) has been long overdue. Though Eden is an internal Walmart initiative, other companies provide similar products in the fight against food waste.
Verigo’s Pod Quality system operates on similar principles to Walmart’s Eden. Pod Quality is the first temperature data logger smart enough to continually translate monitored temperature data into actionable freshness scores of produce in transit.
The key to the new Pod Quality monitoring device is the Quality Analysis engine it contains which translates raw sensor data into a single, actionable metric called Product Life. This metric results from the analysis of a number of variables -- commodity type, initial quality, and product temperature -- and translates them to display the number of days of actual remaining shelf-life of that product. Leveraging over 30 years of research from the USDA and studies with growers such as Driscolls and Berry World, Verigo has developed a growing library of unique Product Life Profiles which each characterize the degradation characteristics of a particular commodity, from Asparagus to Zucchini.
Verigo "smart" pallets will record, analyze, and continuously communicate temperature and remaining Product Life to any phone or tablet within ~15 meters. At any point in the chain, staff can use the Verigo mobile app to view the quality and history of the products onscreen, without having to install any infrastructure of antennas, readers, or gateways. And as long as the phones and tablets used by staff have an internet connection, all data is automatically sent to the Verigo Cloud platform and is visible to management anywhere in the world.
For the first time, it is now possible to do much more than monitor temperatures. With access to information about the shelf-life of individual pallets, stakeholders are empowered to make informed decisions that will reduce shrink by 20-40%. Growers can now see when post-harvest, cooling, and packing operations are degrading shelf-life more than planned, and take corrective action. Wholesalers can see the remaining life of pallets in the warehouse, and prioritize the inventory rotation and routing of pallets to minimize rejections. And receivers can begin evaluating the integrity of the products arriving at the dock before an inspection.
“This concept [smart shelf-life management] has been around for a long time, but it has never actually been developed and released as a usable product. Now that it’s here, we have an opportunity to change how quality is managed to prevent millions of dollars in shrink, and provide unprecedented quality to consumers. It’s truly a win-win.” states Verigo CEO Adam Kinsey.
