progressing vehicle.
As a comparator to the system with a pass rate of 300 households per day, we
modelled an alternative option whereby all households on the collection route utilised
the collection system. Effectively, this gives a comparison between the two situations
of “Competition in the market” (collecting from one in 5 households) and
“Competition for for the market” (collection from all households). In other words, in the
model we assumed to increase the number of households setting out bins in any one
street by a factor of 5. This leads to much greater numbers of households served by
each vehicle each day. Headline results are shown in Table 64-9.
These figures correlate well with the examples provided from Northern Ireland in
Section 64.3.3 of the Annexes. They show that the simple fortnightly collection service
is achievable at a little over €50 per household per year. The more rapid collection
operation when collecting from house to house will also be better utilising the driver
plus two staffing levels on the vehicles.

64.6 Costs of Adding in ‘Brown Bin’ Collections
A more thorough service including weekly food waste collection may be expected to
significantly increase the total capture of materials for recycling, and without
increasing the quantity of waste collected. Disposal costs will also be reduced. As
such, as long as the costs of treatment of the collected food waste lie below those of
treating or disposing of residual waste, then the avoided disposal cost savings will
help to fund the provision of such services. Furthermore, the introduction of food
waste collection services allows for a reduction in frequency of residual waste
collections. This is extremely important.
In Ireland, there has been much made of the contrast between weight-based systems
and other forms of PBU charging. This has been motivated, in part, by a desire to
understand the performance drivers for better performing systems. What this tends to
