To fight food waste, Carulla Supermarket came up with an innovative and accessible tool that helps shoppers better understand how best to store fruits and vegetables. Endorsed by expert nutritionists, "Fresh System" considers the ethylene level of each fruit and all the combinations of fruits and vegetables that people could buy and need to store at home, and easily maps out the best storage for each shopper. When utilized properly, the Fresh System ensures freshness and, crucially, reduces waste.
