Local Authority Municipal Waste

General description

Data on municipal waste was collected using an online reporting system for waste data called 'WasteDataFlow'. In Wales, this is managed by Natural Resources Wales.

There is an apparent discrepancy between the total waste figures given for the 'Waste managed (tonnes)' table and other tables. This is because there is a slight mismatch between the amount collected and the amount treated. This can be a matter of timing if, for example, authorities stockpile waste for later treatment. There may also be some inconsistencies in the measurement since the waste is weighed when collected and again when it is sent for treatment.

Data collection and calculation

Natural Resources Wales validate all local authority returns and require that the difference between the amount collected and the amount sent for treatment must not differ by more than 10 per cent in any quarter.
