Food waste puts a large burden on the finances of each household and local councils in the UK; wasted food is estimated to cost each British household £250–£400 per year, accumulating to £15,000–£24,000 over a lifetime. This comes from the total purchasing cost of the food against what is thrown away uneaten. Additionally, households pay for the collection and disposal of food waste by their local council in the form of council tax. For councils, the cost of food waste comes from its collection and disposal as a part of the waste stream; this is especially an issue for councils that run separate food waste collections.
