the kerbside refuse and the overall waste stream to landfill. Plastics are the second largest component of bothwaste streams.4.3 Comparisons with other districtsThis section provides comparisons of several kerbside metrics between the Waikato district and neighbouringHauraki and Matamata-Piako districts. The data from the other districts is taken from those councils’ jointwaste assessment.4.3.1 Council market share of kerbside refuse servicesIn all three districts included in this comparison, kerbside refuse collection services are provided by both thecouncil and private waste operators. While the councils’ services are used primarily by residential properties,anecdotal evidence suggests that the private waste operators’ services are also used by a significant proportionof commercial properties.A council’s market share of kerbside refuse collection services affects the financial parameters of the council’scollection and may affect the success of council’s waste reduction initiatives. Householders using a private userpaysMGB refuse collection service have no economic incentive to reduce the quantity of refuse they disposeof through the service. On the other hand, householders who use the user-pays council bag services can savemoney by reducing their waste to landfill.Each of the three councils’ market shares of the kerbside refuse market are calculated in Table 14. Theestimates for Hauraki and Matamata-Piako districts are considered to be more reliable than that for theWaikato district, as the information provided by the private waste industry in those districts was more detailed.Table 14: Council Market Share of Kerbside Refuse ServicesTonnes per annum Waikato district Hauraki district Matamata-PiakodistrictCouncil kerbside refuse 9,849 1,262 1,078Private kerbside refuse 1,464 1,224 4,093Total kerbside refuse 11,313 2,485 5,171Council market share 87% 51% 21%Whereas the council’s kerbside services account for nearly 90 per cent of the total kerbside refuse market,Matamata-Piako District Council controls slightly over 20 per cent. Hauraki’s kerbside services account for 51per cent of all kerbside refuse services.These differences are associated with the different proportions of properties receiving kerbside refuse services.Waikato District Council provides kerbside refuse services to a high proportion of properties, which providesprivate waste operators with less of an opportunity to establish an economically-viable collection service.Geographical factors must also be taken into account, as sparsely-populated areas or those with difficult terrainare less economically viable and hence less attractive to private waste operators.4.3.2 Kerbside refuse as a proportion of waste to landfillKerbside refuse services are used primarily by residential properties, with small-scale commercial businessescomprising a much lower proportion (on the order of 5-15 per cent, typically). Larger commercial andindustrial operations use other types of refuse collections, such as stationary compactors, front-loader skips,or gantry bins. As a result, in districts with a relatively low level of commercial/industrial activity, such as ruraldistricts, kerbside refuse services represent a larger proportion of waste to landfill than districts with higherlevels of commercial/industrial activity.Another factor determining the proportion of waste to landfill comprised of kerbside refuse is the relative usageof private wheelie bins. Households that use private wheelie bins tend to set out greater quantities of refuse28
than households that use refuse bags. Table 15 shows the proportion of waste to landfill comprised of kerbsiderefuse.Table 15: Kerbside refuse as a proportion of waste to landfillWaikato district Hauraki district Matamata-PiakodistrictTotal kerbside refuse 11,313 2,485 5,171Total waste to landfill 29,794 6,202 13,234Kerbside as % of totalwaste to landfill38% 40% 39%In the Waikato district kerbside refuse accounts for a very similar proportion of total waste to landfill as Haurakiand Matamata-Piako districts.4.3.3 Per capita waste to landfillThe quantity of waste disposed of to landfill in a given district is related to a large number of factors, including:1) The level and nature of economic activity2) The relationship between the costs of landfill disposal and the value of recovered materials3) The extent of resource recovery activity4) Seasonal fluctuations in population5) The affluence of the population.By combining Statistics NZ population estimates and the landfill waste data in section 4.2.1, the per capita perannum waste to landfill can be calculated as in Table 16 below.Table 16: Waste disposal per capitaWaikato district Hauraki district Matamata-PiakodistrictPopulation 58,459 17,190 30,483Total waste to landfill(tonnes per annum)Tonnes/capita/annum ofwaste to landfill29,794 6,202 13,2340.509 0.361 0.434The estimated per capita waste disposal is higher in the Waikato district than the other two districts.4.3.4 Per capita diverted materialsBy combining Statistics NZ population estimates and the combined council and private diverted materials datain section 4.2.2, the per capita per annum collection of diverted materials can be calculated as in Table 17below.It should be noted that ‘diverted materials’ in this context only includes the commodity-type materials, primarilypaper, kraft, glass, and plastic and metal containers. Council kerbside recycling collections, transfer stationrecycling drop-offs, and transfer station greenwaste drop-offs are also included.Waikato District Council waste assessment 201129
