Less food waste: Supermarkets can save money by giving surplus food away

Phys.org: According to the study data, most product groups generate a net financial gain of around €0.3–0.8 per kilo when prices are reduced, because more items are sold instead of ending up as waste.

For fresh meat, fish and processed meat products, the benefit can be even higher—in some cases exceeding €1.3 per kilo…

…While it typically costs retailers around €0.27–0.36 per kilo in waste and handling costs to dispose of food, donation costs on average about €0.14–0.23 per kilo. This represents a saving of approximately €0.10–0.20 per kilo for most product groups.

My Opinion: Instead of simply disposing of expiring foods at supermarkets, it is more profitable to sell them at a discount just before expiry, or donate them to charity. I don't like wasting food. There is no reason for anyone to suffer from malnutrition. You can both increase your profits, and make cheap or free food available to the poor.
