Special packaging that is used to extend the shelf life of fresh products can also contribute significantly to reducing CO2 emissions. This contribution can be especially important if the products are transported by sea instead of by air, where the special packaging ensures that they are still fresh upon arrival. Researchers at Wageningen UR reported these results as part of an assignment from the Israeli packaging company StePac LA Ltd, producer of Xtend ®.
Moreover, the researchers at the Agrotechnology & Food Sciences Group of Wageningen UR calculated that the CO2 emissions can also be reduced during truck transport if no ice has to be used to keep the products fresh. Larger quantities of product can then be transported with each shipment.
The researchers made the calculations with various transport scenarios, using examples such as white asparagus from Peru, mangoes from Israel and cherries from Chile. The special packaging allows the producer to transport the products by sea instead of by air because it significantly extends the lifespan of the perishable products. Sea transport not only greatly reduces shipping costs, but also reduces CO2 emissions; it therefore has a beneficial environmental effect. For all scenarios in which sea transport was used exclusively, the calculations indicated a reduction in CO2 emissions of more than 90%. For combined transport using both sea and air transport, the reduction was still more than 30%.
The special packaging also makes it possible to avoid using ice in waterproof cardboard boxes with a wax layer; this method is used to transport fresh products such as broccoli by truck. In this scenario as well, the special packaging not only reduced costs but also cut CO2 emissions by as much as 40%.
