Author(s) : GUILPART J.

Summary

Refrigeration preserves our food by preventing its rapid and uncontrolled evolution. It also indispensable to the production of some of today’s processed food. Thus, it permits to dramatically reduce the food waste, while enabling the supply for an ever growing populations living in cities becoming larger and larger. According to these statements, it is commonly accepted that the development of refrigeration is indispensable to the sustainable development of our world.
On the other hand, the refrigeration technologies are based on compression – expansion cycles with phase change of a refrigerant. Most of the refrigerants used have a direct effect on the environment, depreciating the sustainability notion related to sustainability of the food cold chain.
These compression cycles are energy consumers, and in most cases, this energy consumption will increase by using new synthetic refrigerants with a low direct environmental impact: another negative point regarding sustainability.
Therefore, the food cold chain has to be thought with a new sight, integrating its role on the food providing to the world population and its global impact on the environment, in order to put it back is an overall sustainability context.
This presentation aims to address the sustainability of the food cold chain by trying to integrate all these dimensions.
