Throughout the last years, numerous unique businesses have been formed in Sweden to offer suboptimal food both online and in physical stores. Still, Swedish grocery stores stand for 30 000 tons of food being wasted which is directly linked to the still evident unwillingness to offer, purchase and consume suboptimal food.
