London Wider Waste Strategy - London - Greater London Authority

authorities did operate a facility; these were UAs who each operated a waste transfer stations.
Two of the five waste transfer stations were on the river (Northumberland Wharf and Walbrook
Wharf).
The collection authorities were then asked about how waste is transported. Of the 17
authorities that answered this question, over half (i.e. 13) used exclusively diesel fuelled lorries.
(8 WCAs and 5 UAs). However, four authorities used alternative fuels to a greater or lesser
extent as follows:
• One WCA used exclusively LPG fuelled lorries.
• One UA used up to 25% LPG and remainder was diesel.
• One UA had up to 10% of its wastes transported by a combination of LPG and
battery fuelled vehicles.
• One WCA used up to 5% of vehicles fuelled by LPG.
Respondents were then asked to provide information on waste tonnages for commercial and
industrial wastes collected within their borough in 2002/3. Two authorities did not answer this
question. The information is summarised in Table E4 below.
Table E4: Tonnages of Commercial and Industrial wastes collected by
responding London Local Authorities
Authority Minimum Maximum Average Median Totals
WCA 600 28,544 14,209 14,280 127,885
UA 8,000 141,349 45,941 22,000 321,588
Totals 600 141,349 28,092 16,612 449,473
Base: this question was answered by 16 authorities (nine WCAs and seven UAs)
From Table E4, it can be seen that the Authorities that we surveyed collect just under 450,000
tonnes of commercial and industrial wastes. Just over two thirds of this was collected by the
UAs and just under a third by the WCAs. Our survey results suggest that the commercial and
industrial wastes collection services operated by the WCAs are of a much smaller scale than
those operated by the UAs; the WCAs have a lower range, a lower average and a lower median.
Of those authorities that collected industrial as well as commercial wastes, most respondents
provided a combined total to the question on tonnages. Therefore, it was not possible to
provide a breakdown between commercial and industrial wastes from a tonnage perspective.
This question also asked for tonnages for materials for recycling and composting. Just one
authority (UA) gave a recycling figure of 3,129 tonnes whilst a WCA noted that they collected a
negligible amount which was not measured separately.
The questionnaire then proceeded to ask authorities if they could estimate how much of the
total commercial waste arisings collected for or on behalf of the WCA for non-household wastes
could fall into the categories in the table below. A number of the authorities were unable to
provide approximate proportions of these commercial wastes, with eight giving no response to
this question. Five were able to provide data, with the majority of wastes coming from offices,
hotels and retail premises for most of these respondents. However, one authority only gave a
