3 smartphone apps helping reduce food waste around the globe

Food waste is a mounting problem globally. About a third of the world’s food is wasted or lost, according to the WWF, with huge impacts for people, the planet and the economy.

More than 800 million people go to bed hungry every night, according to the United Nations World Food Program.

And the 931 million tons of food that’s wasted every year creates between 8 percent and 10 percent of global carbon emissions, the UN Environment Program estimates.

So what can be done to tackle this issue? Technology is one solution. Around the world, smartphone apps are encouraging people to shift their approach to food waste. Here are three of them.

1. Half-price food at a click

In Egypt, an app called Tekeya lets bakeries, restaurants, grocery stores and dessert shops sell their fresh unsold food at half price. It means bargain food for shoppers, who use Tekeya’s free app to browse and buy discounted food near them.

It also means more profit for the shops and restaurants, by increasing their sales and reducing waste processing costs. Tekeya users can also use the app to donate free meals to charities.

In 2021, Tekeya says it managed to save around 40,000 meals, which is equivalent to 85 tons of CO2.

2. Surplus food scooped up

In the United Kingdom, a similar app called Too Good To Go lets shoppers buy and collect surplus food at discounted prices from local restaurants, bakeries, grocery stores and food manufacturers.

Food is sold in mixed bags. “You won’t know exactly what’s in your order until you pick it up — it’s all part of the surprise,” the company says.

More than 20,000 food outlets are using the app to cut their food waste and almost 9 million shoppers are using the app to buy discounted food, with 12 million bags of food saved from going to waste so far, Too Good To Go says.

Run by Mette Lykke, a World Economic Forum Young Global Leader, the company is also trying to educate people on the difference between “best before” and “use by” labels on food, to prevent unnecessary wastage.

3. Neighborhood food sharing

Olio is a free app that lets you share food with your neighbors, instead of wasting it. This might be food that needs to be eaten before a holiday or leftover catering supplies, for example. Edible food that’s within its “use by” date can be shared.

App users post a photo and details of food they don’t need, and can also browse other listings. Olio says almost 6 million people in more than 60 countries have so far used its app to share more than 52 million portions of food.

What else can we do about food waste?

Not buying too much food is one way we can all reduce food waste, suggests BBC Good Food. Only buy what you can eat before the use-by expiry date, it suggests.

The BBC also advises that leftover food can be used to make new dishes. For example, using old bread to make a breadcrumb topping.

With food waste globally costing $1 trillion a year, governments are starting to take action, according to Winnow Solutions, a technology company that helps commercial kitchens cut food waste.

For example, in 2018, Australia pledged to half its food waste by 2030. Funding food rescue charities was a key part of its policy.

In France, new laws have been introduced to reduce food waste. These include mandatory recycling for any business producing more than 10 tons of organic waste a year.

And in South Korea, food waste in the capital Seoul fell 10 percent — 300 tons of food a day — over four years after a new policy was introduced to charge homes for recycling based on how much food they throw out.
