Too Good To Go, an app operating in the UK, allows users to order leftover food at a discount from restaurants, according to the website. The goal is to help cut food waste.

Users simply log in, pick a restaurant, pay through the app and then pick up their food at a set time—usually around closing or after peak meal times. Orders through the app cost between 2 British pounds ($2.60) to 3.80 British pounds (about $5). Users aren’t able to pick the food items, but they get an idea of the type of food that will be available, according to Business Green.

Users also have the option to give meals to people in need by donating 1 British pound or more through the app. More than l, l00 meals have been donated so far.

To ensure the entire experience is super eco-friendly. Too Good To Go provides recyclable takeout packaging to participating restaurants.

Restaurants using the app make extra money by selling food what would otherwise have been throw away. And Too Good To Go itself makes money by taking a fee from participating restaurants on each sale.

Founded in Denmark last year. Too Good To Go launched this year in the UK and is expanding to other countries. The app is available in Brighton, Birmingham, Manchester and Leeds, and will be in London later this month.

“Food waste just seems like one of the dumbest(愚蠢) problems we have in this world,” co-founder James Crummie told Business Green. “The restaurant industry is wasting about 600,000 tonnes of food each year, and in the UK alone there are one million people on emergency food parcels from food banks. Why do we have these two massive social issues that are completely connected, yet there is not much going on to address them?”

Too Good To Go has already helped cut a significant amount of waste. So far, the app has saved 600 meals from landfills in the UK, reports Business Green.
