The least wasted food? It's frozen food

Research by Waste Watcher for the Istituto Italiano Alimenti Surgelati (Iias): only 15 grams per week against a total of 667

Every week, on average, every Italian throws away almost 7 ounces of food. To be precise, according to the estimates of the International Waste Watcher Observatory, this is 667.4 grams of food per head, a quantity unfortunately growing by almost 18% in the last year. Frozen food, however, does not seem to follow this trend: according to the same Observatory, which carried out an analysis for the Istituto Italiano Alimenti Surgelati (Iias), this is only 14.9 grams, just 2.2%.

Not only that: in the last five years, the consumption of 'frozen food' has increased, but this growth has not been matched by a similar increase in its wastage, which from 2021 to 2025, has remained stable (just over 2%), "confirming the valuable waste-saving virtues of these foods," emphasise Iias.

Frozen foods are in the top 10 of the least wasted foods: their wastage is 37.6% less than that of fresh vegetables and 17.4% less than that of non-fresh vegetables and fruit (in jars or pots).

According to the research, moreover 34% of Italians say they never waste frozen products. Among those who do, the most common causes are poor household organisation or interruption of the cold chain.

"Frozen foods are anti-waste champions not only in terms of food, but also in terms of time and cost: unequivocal," emphasise Iaas, "is their convenience, given the sum of time and food saved, as well as the costs of purchasing and preparing the products.

"Food waste," says Andrea Segrè, scientific director of the International Waste Watcher Observatory, "should not be read exclusively as incorrect individual behaviour. Rather, it is an indicator of socio-cultural fragility and educational marginality, and if we want to combat it in a systemic manner, we need to strengthen food education policies, pay greater attention to information on labels, and also promote access to efficient household appliances and smart solutions for managing food in the home, so that Italian families can transform their freezers into smart and sustainable 'food reserve centres'. Our survey, in fact, clearly revealed that frozen food is a valuable ally against waste'.

"In a country like Italy," adds Giorgio Donegani, president of Iias, "where the problem of food waste has taken on worrying proportions, with double-digit growth by 2025, the consumption of frozen products can become an important element in the fight against waste. Not only because we throw away a very small percentage of these products, but because frozen foods are, by their very nature, a waste-saving solution par excellence. Food waste is a social issue that needs to be given serious thought, given that what is wasted worldwide could feed a third of the global population. Wasting not only means not being able to guarantee enough food for everyone, but also losing valuable resources used in production, such as fertile soil, water, energy, fertilisers. Frozen products help in the fight against food waste because they allow optimal utilisation of raw materials that arrive ready for use in the kitchen, maximise production yields, reduce waste throughout the supply chain, and reduce pollutant emissions into the atmosphere'.
