Challenge 4: Food Waste and Safety
Moving from middleman to the last line of defense.
Traditionally, cold storage warehouses have functioned as upstream stops on a long journey ending at grocery and retail stores and ultimately, the consumer. The buffer between production and consumption distributed responsibility of food safety between all parties involved in the product’s journey. The growth of business-to-consumer (B2C) direct delivery companies, however, circumvents traditional supply chain workflows and shifts direct customer contact further upstream. These days, a frontline worker at a warehouse could be the last line of defense for somebody’s dinner.
“Now, what we do impacts somebody at their home. There is no middleman. We have to have the highest level of efficacy and attention to detail because we’re the final quality check.” – Dr. Stephen Neel, Lineage Logistics Director of Food Safety
Doing our part to reduce food waste.
There are many factors that can cause food waste – from spoilage and disruptions in temperature regulation to package damage. Even relatively small differences in temperature can mean a big difference in the quality of perishable foods. Maintaining the quality of perishable foods is difficult, especially when multiple players are handling and moving the product. Lack of visibility and human error are the two most common causes of food spoilage during transportation, processing and storage.
According to the Boston Consulting Group (BCG), the amount of food waste created in the supply chain will rise by 1.9% annually from 2015 to 2030. You may think this is a small growth, but when put into perspective, the current 1.6 billion tons wasted every year will increase by 30.4 million tons (Abecasis, Alexander, Meyer zum Felde, Pralle, 2020).
The Food and Agriculture Organization of the United Nations reports that nearly $1 trillion of food is lost or wasted every year worldwide. This figure includes food wasted by retail chains or consumers along with food that is lost, damaged or expires as it makes its way through the supply chain. It’s enough food to feed nearly 2 billion people. There are 1 billion undernourished people in the world (UNWFP, 2021). Optimizing the cold chain and dynamic routing can simultaneously decrease waste and undernourishment (Leonard, 2019).
Solution: Optimize food quality and minimize waste with automated, yet agile, workflows.
In the food supply chain, maintaining fundamental compliance through the entire food journey is the primary goal. From there, companies need to decide between merely meeting the minimum standards or going above and beyond, developing best-in-class practices of combining quality and maximization into food safety.
Automation in both decision-making and material handling enables best-in-class practices. Computers can make decisions on the basis of more factors and more information than a human ever could and provide traceability that human decisions cannot. Automated material handling systems put the pallet exactly where the control systems direct it; there is no possibility of a pallet getting lost if it’s been placed by a robot.
Automation removes human error and allows you to focus on optimizing quality. Maximizing quality requires understanding thermodynamics, biology and our customers’ products. Data collection, data analysis and automation ensure that the highest quality of food is available to consumers, while surpassing standard industry guidelines.
Automation in action: Blast freezing line
Blast freezing, the energy-intensive process in which freshly produced perishable goods are safely and rapidly chilled to below-freezing temperatures to retain freshness, is a critical part of the cold chain process. Blast freezing is what makes food frozen prior to storage and shipping.
Lineage’s Data Science team has studied and improved the existing blast freezing designs throughout its portfolio. By utilizing techniques, such as computational fluid dynamics (CFD) and finite element analysis (FEA), we have created and patented new blast freezer designs with improved freezing airflow, which results in higher product freeze quality and enhanced energy efficiency. The newer designs are able to freeze products in as little as half the time of a traditional blast freezer while still being 20% more energy-efficient. Getting perishables to the correct temperature in half the time is just one of the ways that Lineage is maximizing quality.
Lineage’s advancements in blast freezing have not gone unnoticed. We received the Department of Energy’s Better Plants Better Project Award in 2020 as a result of this research and implementation. (In addition to the same awards in 2019 and 2021 for different energy-related innovations.)
Achieving food optimization through automation.
The evolution of the cold chain increased the prominence of the warehouse worker; She or he is front and center as the last line of defense between the consumer and potentially harmful food. Changes in the food supply chain increase the stakes for the cold chain; it must ensure food safety and maximize quality.
We must elevate food safety standards while simultaneously reducing food waste. From an industry and humanitarian viewpoint, the amount of waste in the cold chain adversely affects economies and communities around the world. Eliminating waste in the cold chain is an essential step toward a more sustainable future.
The most-direct path to achieve food safety and food optimization while concurrently reducing food waste is through automation. Automation is essential, not only for the efficiencies that it brings to the industry but to also continuously improve food quality. As consumer demand escalates and changes in ways that provides fewer buffers between the producer and the consumer, weaving in automation with traditional warehouse operations is the only answer for safely keeping up with demand.
Over the last several weeks, we’ve covered numerous challenges facing the cold chain in our series Automation Is. Whether addressing labor shortage concerns, increased consumer demand, sustainability or food optimization, it is clear that automation, A.I., and the I.o.T. are the surest and most efficient methods to achieve our shared industry goals.
For a practical overview of Lineage’s automation philosophy, look for our next series of blogs when we examine automation’s place in the cold chain. We will explore the flexibility of these new technologies and how they can seamlessly integrate into current workflows. We will also assess how to effectively integrate proprietary software throughout your operations and what to expect during the experience. Finally, we will cover ways to merge your team members with these new technologies.
Ultimately, automation in the cold chain is fluid. We are continuously investing in process improvement, and as we unlock new and more effective ways of delivering food to the world, we’ll share these developments with you.
