How to Reduce Food Waste?
Sensing CO2, Humidity and Temperature in Cold Chain Logistics
The Food and Agriculture Organization of the United Nations has found that one third of all food is wasted. For fruits and vegetables it is even more tremendous as 45% of all fresh products go to waste. All this totals in a yearly loss of $85 billion in the United States alone. In addition to the loss of the food, all resources (land, water, energy) required to produce this food are lost as well. The related greenhouse emissions are so immense, that it would be the world's 3rd largest emitter if it were its own country. On top of all that, these food losses have a major impact on the food security and hunger in the world’s poorest countries. Clearly there are more than enough reasons to reduce food waste!
To achieve a reduction of food waste it is crucial to consider the entire supply chain from farm to fork. Many fruits and vegetables, such as bananas, are transported and stored in a controlled atmosphere (CA) to preserve freshness. CA parameters are carbon dioxide (CO2) as well as humidity and temperature (RH/T). The exact conditions depend a lot on the exact commodity, with typically a low temperature, high humidity and CO2 concentration somewhere between 1% and 20%. Proper monitoring and controlling of the transportation conditions allows to prevent losses by proactive action and improve the quality of the supply chain. Sensirion has just the right sensors for the job!
