Oelofse and colleagues measured the actual amount of food waste disposed of into municipal bins by households in the City of Johannesburg and Ekurhuleni.

The food disposed of amounts to 12kg per person per year in Johannesburg and 8 kg in Ekurhuleni – a contribution of about 51000 tonnes in Johannesburg and 25000 tonnes in Ekurhuleni to the municipal solid waste disposed of on already stressed landfills.
