Half of all food waste is caused by food reaching its use-by date. By adding shelf-life days, you can cut waste. In turn this can reduce emissions linked to climate change as well as make the planet’s resources available to feed more people.
There are also cost savings and benefits to uncover from longer shelf life and the associated waste reduction at different stages of the supply chain such as:
