How A Sustainable Cold Chain Can Be Established In Industry

By Cindy H. Cassidy


Cold chain shipping plays a vital role in the transport of most biological products such as vaccines, and some food products as well. However, one main concern is the impact that this process has on the environment, and what can be done to reduce its overall carbon footprint. In order for organizations to produce a sustainable cold chain, they must closely examine aspects such as packaging, disposal, and waste reduction.

The key is to identify packaging types which both protect the integrity of the products they contain, and also don't place a high degree of stress on the environment in their manufacture, transport, or disposal. "Green" packaging options can be biodegradable, made from sustainable materials, or reusable. If the amount of packaging is also less, this means further saving of resources and reduced transportation needs.

The best way for packaging companies to get a clear picture of how their shipping methods measure up in terms of the carbon footprint they produce is to hire the services of an organization which specializes in this area. These experts will do a comprehensive analysis of the packaging life-cycle used and point out any improvements needed.

Eliminating waste is one useful tactic for increasing the sustainability of the cold chain shipment system. Minimizing the amount of packaging materials not only means that fewer raw materials are required, but also that it can optimize every delivery allowing more to be shipped in one load.

The concept of reusable packaging also lends itself to eco-friendly shipping practices. Packages that can be readily cleaned and returned to the supplier after delivery may initially cost more to develop but in the long run it will end up saving money and resources. Materials used must rank high in durability if they are to be used repeatedly.

The implementation of recycling can also contribute considerably to the green factor where shipping is concerned. When recovered materials are used to manufacture packaging this eliminates the extra energy needed to ship and process new material, cutting down on greenhouse gas production and space that would have been take up in landfills.

In some cases it is unavoidable that packaging materials will have to be send to a landfill, this is why the material selection is so important. Choosing materials which are less destructive to the environment and will not break down to release dangerous methane gas is critical. One example of this is expanded polystyrene which has the added advantage of aerating the soil to stimulate plant growth.
