Auchan, Aldi Harness Technology To Reduce Food Waste

Auchan Retail Portugal and Portuguese non-profit organisation Dariacordar have launched a new mobile app that calculates food waste.

The Calculadora Contra o Desperdício Alimentar (Calculator Against Food Waste) app is designed to help consumers understand the amount of food that they waste and the environmental and economic impact of their actions.

Auchan seeks to help consumers make more informed and conscious decisions about food waste through this initiative.

It was developed in collaboration with Portuguese consumer protection organisation Deco Proteste. It is available free of charge to all iOS and Android users and can be accessed directly through the website.

The app is easy to use and provides users with personalised information about their food waste patterns. Users can track the amount of food they waste by weight and cost, and the app calculates the environmental impact of this waste. The app also provides users with tips on how to reduce food waste.


Auchan Retail Portugal has a solid track record in combatting food waste and has already donated €1.7 million to 149 social-solidarity institutions across the country in the first half of this year.

Auchan has reaffirmed its commitment to sustainability and an awareness of the importance of reducing food waste at all stages of the production and consumption chain. It also gives priority to social responsibility and solidarity with those who face hunger.

Aldi Spain

In neighbouring Spain, Aldi has launched a new platform, called Sabrosas Sobras (Tasty Leftovers), to help reduce food waste.

The platform uses AI to generate recipes based on the ingredients that users enter, helping to use leftover food, rather than throwing it away.


The recipes are varied and creative, so users can find something to please everyone.

The launch of the platform is part of Aldi’s commitment to sustainability and reducing food waste.

In 2022, Aldi prevented the wastage of more than 6,595 tonnes of perishable products through a variety of measures, including direct food donations to social entities and discounts on items with preferential consumption or that were near expiration.

The discounter also applies a 30% discount on certain items with a best-before or near-expiration date.

In addition, Aldi implements measures that allow food waste to be avoided indirectly, such as improvements in logistics processes, the redesign of packaging, and the optimisation of orders at the point of sale.
