Deep dives
The Shipping Container Revolutionizes Global Trade
The invention of the shipping container in 1956 by Malcolm McLean revolutionized the way goods are transported. It eliminated the need to unload and reload goods from one container to the next, making the process faster and more efficient. As a result, the shipping industry became more streamlined, with fewer workers required. However, the shipping container was initially not suitable for perishable products, which continued to be transported using bulk cargo. This led to market flooding and wastage. Eventually, in the 1970s, refrigerated containers, known as reefers, were developed to address this issue.
The Research Journey to Improve Reefer Technology
Barbara Pratt, a physics graduate, got involved in a research project in the 1970s to understand the problems with shipping perishable goods. She and her team built a mobile lab inside a shipping container to monitor produce from farm to destination. Their research led to groundbreaking insights, such as mapping airflow in reefers and determining the optimal capacity for produce. They also influenced new packaging and preparation methods for better product preservation. Their work contributed to the availability of fresh produce year-round, allowing global access to fruits and vegetables.
The Impact and Future of Reefer Technology
Reefer units are now controlled by microprocessors, enabling real-time monitoring of temperature and conditions. High-tech reefers have become reliable and affordable, even for fragile products like fish and flowers. The improved technology has reduced the reliance on air cargo and the need for special ripening facilities. It has also facilitated the global market access for small farmers and allowed consumers to enjoy a wider variety of fruits and vegetables throughout the year. While challenges and environmental concerns persist, reefers have played a significant role in changing the way perishable goods are shipped and consumed.
There are around 6,000 cargo vessels out on the ocean right now, carrying 20,000,000 shipping containers, which are delivering most of the products you see around you. And among all the containers are a special subset of temperature-controlled units known … Continue reading →
