The nations of the world produce enough food to feed their populations. Still, food waste and food loss have become a global crisis. One-fifth of the world’s food is lost or wasted every year. This food loss or waste not only leaves many people hungry but also causes significant economic losses. There are several reasons for food waste. One reason is that the crops get spoiled before they can be harvested. Climate change and greenhouse gases also lead to food being wasted.
The food that is produced travels through the supply chain to reach the consumer. This also means that food gets wasted in the supply chain at different points. One point in the supply chain where food is wasted is at the consumer and retailer levels. This happens when food purchased for resale is wasted because it has expired or because more food was bought than needed. Another point in the supply chain where food is wasted occurs before it reaches the retailer. This can happen during crop harvesting, during the transport of food, or when food is processed or stored. This happens because of poor infrastructure and a lack of proper processing and storage facilities.
It is important that the problem of food waste or loss is addressed so that people do not go hungry and resources are not wasted. One of the solutions to the problem of food waste or food loss is the use of cold chain logistics.
What is cold chain logistics, and how can it handle the problem of food waste?
Cold chain logistics are popularly used in the supply chain to keep perishable food safe. In cold chains, temperature-controlled, coordinated processes ensure that perishable food materials are not wasted at any point in the supply chain. The supply chain uses this type of logistics from food production through transportation, packaging, and storage to delivery to consumers. In effect, when consumers receive these food products, they are safe and not wasted in any way.
Cold supply chains use specialized equipment and technologies at every step to keep food safe and fresh. During the packaging stage, the cold chain uses gel packs, insulated materials, and smart containers to package food with care. For storing perishable food items, cold chains make use of cold rooms and refrigerated warehouses. During food transportation, cold chains use refrigerated trucks and containers, along with real-time temperature monitoring technologies, to avoid food waste.
Advantages of cold chain logistics
Cold chain logistics offer several benefits in addition to helping solve the food waste crisis, including:
- Since cold chains ensure that perishable products are maintained at regulated temperatures, there is less loss, as food is less likely to spoil or degrade.
- With the help of cold chains, several industries can enhance the shelf life of their products. When food products are stored and transported at controlled temperatures, their shelf life is extended, allowing consumers to get fresh, high-quality products.
- The food products that consumers receive through cold chains are safe, as regulated temperatures help prevent bacteria and pathogens from adversely affecting the food.
- Beyond food safety, cold chains also support economic efficiency by reducing financial losses for farmers, distributors, and retailers. When less food spoils during transit and storage, businesses save money while more people gain access to nutritious meals.
To sum it up
One of the most effective ways to address the global food waste problem is to use cold chain logistics for storing, packing, and transporting food. This ensures that consumers receive fresh, high-quality, and safe food products, thereby reducing food loss and waste.
