Table 4.6: Number and weight of samples for commercial wastes for the SWAP
report (based on SWAP report 2001)
Sector Total number of samples Total weight of samples (kg)
Offices 4 2,141
Retail 11 1,317
Hospitality 26 9,059
Total 41 12,517
4.33. As can be seen from this table, the number of samples for the office sector in particular
is very small, and there are also relatively few for the retail sector, although a higher
weight of samples has been recovered from the former. In comparison, the hospitality
sector has been subjected to a more detailed survey, both in terms of number and
weight of samples.
4.34. The results from the SWAP survey, and particularly for the office and retail sectors,
should be regarded with a certain level of caution due to the relatively small sample
number and weight. Nevertheless, these waste streams are not necessarily expected to
vary a great deal. Further, the survey is recent and detailed in terms of the categories of
waste that it covered. It also was carried out over a year which allowed temporal trends
to be captured. It is the most useful compositional survey that was identified during our
study and hence a summary of the results is presented in Table 4.7 below.
