Each year, a large amount of food is wasted due to inefficiencies in managing food waste at the store level. This not only contributes to the ongoing climate crisis—accounting for 6%-8% of human-caused greenhouse gas emissions—but also adds to the increasing financial strain on households, with grocery prices in Spain rising by 38% over the past three years.
