Industrial design graduate Solveiga Pakstaite’s Bump Mark uses a gelatine-based label to let consumers know when food has passed its prime. This little bump could cut a 4 million tonne mountain of UK food waste and save £12 billion. The result of her work in progress is a label which is attached to food packaging and changes shape when the produce deteriorates. When food is fresh to eat the label is smooth and curved, when it has decayed, a plastic bump emerges. This will not only be a huge aid to those who are visually impaired but will also offer a much more accurate reading which should lead to less waste.
