The smart store scale Grönsaksrabatten

Bachelor thesis by Isabelle Kjellström, Simon Dybeck, Jonas Larsson, Oliver Palmberg, Filip Sperr and Wilhelm Wessblad in collaboration with WhyWaste AB.

Grönsaksrabatten is a store scale where fruits and vegetables can be scanned in order to receive a discount for extra ripe greens. The store scale consists of a modified scale where camera technique and well-thought-through packing surfaces simplify the interaction with the customer.

The concept goal is to influence consumer’s and store owner’s view on extra ripe greens into something positive. In addition, the concept is also meant to save time and resources for the staff who spend hours sorting out overly ripe greens, as well as to reduce the producers’ and the stores’ food waste.
