Welcome to the Kerry
Food Waste Estimator

Millions of tonnes of food are thrown away each year. And this not only costs money, but water, energy, labour, CO2 emissions – and food that other people need.
Whether you’re a food manufacturer or a concerned consumer, use our calculator for a guide to what you could save, for yourself and the planet.

Manufacturers

Estimate food waste reduction
from shelf-life extension

Here are the inputs that you will need

  • Product type (from selection)
  • Region (from selection)
  • Volume produced
  • Current shelf-life days
  • Extra shelf-life days to simulate waste impact
  • Current waste statistics (across entire supply chain)*

Consumers

Calculate the impact of a % food
waste reduction in your home

Data you’ll need:

  • How many people live in your home
  • Your region
  • % waste reduction you would like to achieve
  • Average weekly spend on groceries*
* Optional - all others are required inputs

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:

  • Improved efficiency for sustainable growth
  • Reduced returns
  • Your production reaches more people
  • Fewer deliveries
  • Increased consumer satisfaction
  • Full valorisation of raw materials
