SOUTH TARANAKI DISTRICT COUNCIL WASTE ASSESSMENT 2018 1 Introduction The Waste Minimisation Act 2008 (WMA) requires territorial authorities (TAs) to review and implement Waste Management and Minimisation Plans (WMMPs). The WMMPs are intended to be the guiding documents for TAs to promote and achieve effective and efficient waste management and minimisation within their District. The Waste Assessment (this document) establishes the planning foundation for the WMMP by providing background information. The TAs in the Taranaki region (the South Taranaki, New Plymouth and Stratford District Councils) are committed to collaborating regionally to achieve efficiencies and effectiveness in waste management. The Taranaki Regional Council (TRC) hosts the Taranaki Solid Waste Management Committee (TSWMC), on which each TA has a sitting member. The three TAs, New Plymouth (NPDC), South Taranaki (STDC) and Stratford (SDC) district councils and the TRC, contribute to funding a Waste Minimisation Officer (WMO) who serves the Committee and is central in implementing the Regional Waste Strategy and the WMMPs. The region has a single landfill and the TAs have awarded a single contract for the residential kerbside waste and recycling collection for the region. In continuing with this regional approach to waste management and minimisation, this Waste Assessment has been developed with input by the three TAs. A regional Waste Assessment template has been developed and regional waste data and regional options are considered where applicable. 4|

SOUTH TARANAKI DISTRICT COUNCIL WASTE ASSESSMENT 2018 1.3 Structure of this document This Waste Assessment has been prepared in accordance with Section 2 section 51 of the WMA and follows the guidelines provided by Where Do we Want to Be? the Ministry for Environment2 (MfE). This section documents our vision, goals, objectives and targets. A gap analysis between this and our waste situation is provided.

SOUTH TARANAKI DISTRICT COUNCIL WASTE ASSESSMENT 2018 1.5 Completeness and Accuracy The Council has a responsibility to plan for all waste generated within the District when considering waste infrastructure and services. It has detailed information on the collection and facilities operated by it or on its behalf. This includes Council-provided kerbside collection services, transfer stations and the landfill. However there is a range of private companies involved in the collection, diversion of waste and alternative disposal (e.g. cleanfills) within the District and wider region, from which information is more difficult to capture. Surveys have been undertaken to gain a wider understanding of waste quantities and their destination, and this data is used where applicable. However it must be noted that the response rate from the surveys is generally low (less than 15% response rate) and the data is therefore only an estimate. Initial consultation with the community and commercial sector was held during the development of the waste assessment to gain a broader understanding of behaviour and perceptions with regard to waste. This, in combination with the surveys and Council data is sufficient to identify the areas that should be prioritised, and to outline the role that the Council could potentially play in resolving the issues relating to both Council and non-Council controlled waste. Targeted consultation to confirm the appropriateness of the proposed options is prudent and will be sought through the Special Consultative Procedure, which is required as part of the development of the WMMP. |7
SOUTH TARANAKI DISTRICT COUNCIL WASTE ASSESSMENT 2018 2 The Waste Situation This section contains information about waste and diverted material in the Taranaki region and in the South Taranaki District that is generated, recycled, recovered, treated or disposed of to landfill. The information includes waste infrastructure and services, and data about quantities, trends, composition, source and destination of waste and diverted materials. This information provides the basis for projecting future demand for waste management and minimisation services, as presented at the end of this section. Data has been collected from the following sources: • landfill and transfer station weighbridge quantities; • the findings from a landfill and transfer station solid waste analysis protocol (SWAP) conducted in September 2016; • a kerbside SWAP conducted in November 2016, December 2016 and January 2017; and • surveys of industries. 2.1 Solid Waste Framework 2.1.1.

SOUTH TARANAKI DISTRICT COUNCIL WASTE ASSESSMENT 2018 2.3 Existing Waste Services and Infrastructure A variety of stakeholders is involved in waste management and minimisation services within the region and the District. The three TAs in the region have a joint regional contract for the collection of urban residential kerbside refuse, recycling, and greenwaste; and the operation of key transfer stations. A number of private service providers offer waste services to the rural community, the commercial sector, and residential customers paying for a collection service. A growing number of community sector organisations are also involved in waste services TABLE 1 - SUMMARY OF WASTE INFRASTRUTURE AND SERVICES IN TARANAKI Infrastructure/Service Council Provided Other Providers REDUCE Education/ Regional education strategy and campaigns* Taranaki Environmental Education Trust behaviour TRC Education Officer available for waste Enviroschools change lessons Taranaki Conservationists (across waste Regional Waste Minimisation Officer.

KERBSIDE WASTE QUANTITES The three TAs in the region provide a kerbside refuse and recycling collection for urban residential households. The quantity of kerbside waste collected in the South Taranaki District between 2010 and 2016 has remained reasonably stable at around 3,600 tonnes per year (Table 6). 2.5 Waste Generation per Capita Waste per capita is an indicator for waste generation that looks at the total amount of waste produced, divided by the total number of people in a defined area. It is an indicator of average waste production on a per person basis, but is not directly equivalent to the amount of waste an individual throws away each year, as much of the waste is produced from commercial sources. The per capita disposal figures for kerbside refuse can be influenced by: • Changing proportions of the population serviced by Council collections. • Different levels of commercial and industrial activity (a greater level of commercial and industrial activity in South Taranaki influences the per capita rate for this location). • Missing data (private collectors may not be separately accounted for at transfer stations). • Unknown cross-district waste movements, e.g. New Plymouth total waste per capita is higher than the other two districts but does not necessarily comprise waste sourced only from the New Plymouth District. Many of the private waste service providers may service the whole Taranaki region but, as they are based in New Plymouth, the waste is recorded as being sourced from within the New Plymouth District. It is difficult to determine any cross-district waste movements. The waste per capita for kerbside collection and for the total amount landfilled from waste collected by the Council were calculated using 2009/10 and 2015/16 data. For South Taranaki, kerbside waste sent to landfill remained constant while the waste per capita for total waste to landfill reduced from 0.4 to 0.32 T/capita/annum (Table 7). Once again, the lower volumes received at the transfer station since October 2015 explain the decrease in total waste per capita.

SWAP RESULTS 1% 3% A SWAP survey was conducted in 2016 to analyse the composition of 23% waste disposed of to landfill, at the main transfer stations and via the 5% Councils’ kerbside collection services. Landfill The SWAP survey analysed the composition of waste sent to the 6% Landfill (Figure 8). Organic material was the largest component of the overall waste to landfill in 2016, comprising 23% of the total, by 16% weight. Timber was the second largest component, comprising 16% 10% of the total. Paper, plastic and rubble comprised similar proportions, from 10% to 14%. 11% Most waste streams reduced in weight between the 2010 and the 14% 2016 surveys, but as a proportion of the composition, organic waste entering the landfill showed the biggest reduction between 2010 and 1% Nonferrous metals 6% Textiles 2016, declining by 7% of the overall waste (Figure 9).
