Hundreds of people visited the new store since its grand opening that took place in Copenhagen on Monday. The new store, called WeFood, will be selling a variety of products that would otherwise end up in the trash because of damaged packaging or because they are past their expiry dates. The prices are 30 percent to 50 percent lower than those in regular shops.

The store was officially inaugurated by Denmark's Princess Marie and the minister for food and environment.

"WeFood is the first supermarket of its kind in Denmark and perhaps the world, as it is not just aimed at low-income shoppers but anyone who is concerned about the amount of food waste produced in this country.

"Many people see this as a positive and politically correct way to approach the issue," Per Bjerre, the leader of the project, said at the opening.

The Danish food minister also praised the initiative.

"It's ridiculous that food is just thrown out or goes to waste. It is bad for the environment and it is money spent on absolutely nothing. A supermarket like WeFood makes so much sense and is an important step in the battle to combat food waste," Eva Kjer Hansen said.
