Waste Assessment 2017 Auckland’s Waste Assessment 2017 The preparation of the waste assessment has relied on information from multiple sources, including SWAP analysis, reporting of domestic waste data under the licensing requirements of the Solid Waste Bylaw 2012, contracts, consents, and annual reports. The accuracy of these sources is contingent on the best information available at the time and the degree of disclosure from the waste industry. It is not possible to calculate, with precision, up-to-date tonnage and composition of waste being disposed to landfill in the Auckland region without mandatory industry disclosure. Information has also been sought from landfill and refuse transfer station operators, who have no obligation to supply the requested information. In some instances information has been voluntarily provided, however on others the requests have been declined to supply information for this purpose. Financial analysis and modelling has relied on the best financial information available at the time of drafting of the waste assessment.

This study aimed to quantify retail food Food waste waste in New Zealand (NZ) and identify key drivers for food waste reduction, using a mixed-methods, ob- Sustainability servational study design that consisted of three parts: onsite food waste audits undertaken in 16 selected stores Compost (complete data from 11 stores); semi-structured interviews with key retail staff from each store; and obtaining Supermarket existing data from retailers. Retail food waste in NZ was estimated at 13 kg/capita/year for all food waste and Retail store diverted product (i.e. all food not sold or utilised at a retail level), which included 5 kg/capita/year designated as Food loss Landfill food waste (i.e. food directed to landfill, protein reprocessing and compost), with 3 kg/capita/year of this sentto landfill. Fresh vegetables (27%), bakery (23%), meat and fish (19%) and fresh fruit (17%) contributed themost to discarded product. The motivators for encouraging food waste reduction were: concern for the environment; making profit; caring for the community; and doing the ‘right’ thing. The barriers to food waste reduction were: training and educating staff; food safety concerns; quality standards; availability and capacity of waste diversion avenues; and lack of available resources.

We estimate that in 2018 New Zealand generated 17.6 million tonnes of waste, of which 12.7 million was disposed of in landfills including farm dumps. Some areas are facing urgency to invest in new solutions as the waste flow has increased, severely shortening the projected life of existing local landfill. One solution proposed to reduce the amount of waste going to landfills is Waste to Energy (WtE). WtE is the process where waste is incinerated to generate heat and electricity. In May 2018, the Ministry for the Environment through the waste minimisation portfolio adopted a circular economy policy approach.

  • Report 6 the State of Deconstruction in New Zealand
    REPORT 6 THE STATE OF DECONSTRUCTION IN NEW ZEALAND Authors: John B Storey, Morten Gjerde, Andrew Charleson, Maibritt Pedersen (Centre of Building Performance Research, Victoria University, Wellington, New Zealand) ABSTRACT: This paper discusses the state of deconstruction in New Zealand. It outlines specific circumstances in New Zealand which affect deconstruction and materials reuse. The paper details techniques, strategies and examples of deconstruction in New Zealand, and provides an overview of legislation, guidelines, governmental bodies and industry organisations that are associated with construction and demolition as well as waste minimisation in New Zealand. The key document relating to the potential for wide spread implementation of deconstruction and other materials reuse strategies in New Zealand is the recently published a strategy document ‘The New Zealand Waste Strategy – Towards Zero Waste and a Sustainable New Zealand 20021, which sets the nation a target of reducing construction and demolition waste going to landfills by 50% of the 2005 figure by 2008. Half of the Territorial Authorities in New Zealand have set themselves the even more ambitious target of zero waste by 2015.

  • Tu Kaha: Stand Tall Fronting up with Wicked Solutions
    2017 EIANZ ANNUAL CONFERENCE Tu Kaha: Stand tall Fronting up with wicked solutions Life cycle-based environmental management of food-related waste in a student dining hall Sarah Sandilands1 and Sarah J. McLaren1,2 1 IAE, Massey University, Palmerston North 2 New Zealand Life Cycle Management Centre. C/O Massey University, Palmerston North INTRODUCTION Environmental problems require forward thinking and innovative planning to deliver robust and effective solutions to stand the test of time. Food waste (FW) quantification, behaviour and insight is largely focused on consumers, particularly households, as they are viewed as the biggest FW producers along the supply chain (Visschers, Wickli, & Siegrist, 2016). In this Figure 1: Interior of student dining hall at Massey University context, this paper discusses relevant FW management technologies, provides a stimulating approach in waste minimisation utilizing the nudge theory, and helps develop a better understanding of the environmental trade-offs between compostable containers and reusable plates in the student dining hall at Massey University, Palmerston North (Figure 1). SYSTEMATIC REVIEW With many existing life cycle assessment (LCA) studies for FW management, it was determined that a systematic review would be beneficial in providing insight and recommendations for FW in the student dining hall. Zumsteg, Cooper, and Noon (2012) defines a systematic review as an organized evaluation of existing literature with the objective of answering a specific research or application question with a mixture of the best available evidence and data. This review methodology has proved important in producing robust synthesized results from existing research which would otherwise prove difficult due to inconsistent methods and differing assumptions that can affect the outcome found in individual studies (Heath & Mann, 2012).

  • Moving Toward an Integrated System for Waste Reduction in Hamilton
    MOVING TOWARD AN INTEGRATED SYSTEM FOR WASTE REDUCTION IN HAMILTON Howard Mitchell Gavin Bush Environmental & Refuse Manager Central Region Manager Hamilton City Council Waste Management NZ Ltd SETTING THE SCENE The management of waste in New Zealand has evolved during the last twenty years into an extremely complex and interwoven mix of issues. Public concern about environmental pollution has been linked to waste disposal and the consumption of resources, however there is an ongoing desire for economic growth, which is at odds with the minimisation of waste. The participants include service providers in the public (local authority) and private sectors (waste companies), waste generators (the entire community) and regulators (local, central and regional government). Their operations are not well co-ordinated. In an attempt to co-ordinate a national approach to waste, the Ministry for the Environment presented the NZ Waste Strategy in March 2002, which set long term goals and expectations. The Waste Management Institute of NZ has developed the LifeAfterWaste (LAW) principles, which aim to move the problem “up the pipe” and to harmonise the activities of resource use and waste management in a way that will ensure a better environment. LAW recognises that without a high quality environment and a truly integrated and sustainable approach to resource use, consumption and disposal, there can be no long term improvement in the quality of life. On top of all that, service providers strive to be customer focused in delivering what customers want at a price that is acceptable, while governmental agencies strive to educate the consumer to take a considered approach to resource use.

  • Is Voluntary Product Stewardship for E-Waste Working in New Zealand? a Whangarei Case Study
    sustainability Article Is Voluntary Product Stewardship for E-Waste Working in New Zealand? A Whangarei Case Study Vicktoria Blake 1,*, Trisia Farrelly 2 and Jonathon Hannon 3 1 Faculty of Primary Industries, Science and Environment, Toi Ohomai Institute of Technology, Tauranga 3110, New Zealand 2 School of People, Environment, and Planning, Massey University, Palmerston North 4442, New Zealand; [email protected] 3 School of Agriculture and Environment, Massey University, Palmerston North 4442, New Zealand; [email protected] * Correspondence: [email protected] Received: 30 April 2019; Accepted: 20 May 2019; Published: 30 May 2019 Abstract: New Zealand currently manages its annually-generated 99,000 tonnes of e-waste via voluntary product stewardship schemes. Limited data is available to determine the success of this approach. This lack of data is cited as the logic preventing the declaration of e-waste as a priority product by the Minister for the Environment which would trigger the enforcement of mandatory product stewardship. This case study involved an online survey of 264 Whangarei District householders asking questions about e-waste creation and management, as well as analyses of local services, and local and national policy. It found that only 1.8% of the estimated e-waste created in the district is recycled by municipal services, with the ‘cost to recycle’ and ‘a lack of knowledge’ presenting barriers to engagement in these services. The ‘lack of ability to repair/the cost to repair’ was found to be the most significant driver for e-waste creation. The adoption of mandatory product stewardship for e-waste was recommended to ensure robust and transparent data collection, see recycling services become more accessible, and raise awareness of these services, thus reducing the value-action gap.

MUNICIPAL SOLID WASTE MANAGEMENT STRATEGIES: IMPACT OF WASTE GENERATION BEHAVIOURS IN RURAL AND URBAN COMMUNITIES. by LONE MORRIS JORGENSEN A Thesispresented inpartial :fulfilment of the requirements for the degree of Doctor of Philosophy ID Environmental Technology MasseyUniversity, Pa1merston North,New Zealand. 1996 To my husband Jens. A patient and supportive partner. ABSTRACT The waste generation characteristics of households was investigated in relation to waste management principles and philosophies in urban and rural New Zealand, to evaluate current practices regarding municipal solid waste at the national, district- and city council leveL Two selected councils, one rural and one urban, were studied in detail. A household sample from each council was surveyed to establish the trends in household waste generation. The results from these surveys were compared using statistical analyses. The initial results suggested that rural and urban households show significant differences. Further analysis, involving a detailed case study of a rural settlement, suggests that these differences arise from the economic signals received from the council and not from population structure and culture, although some subgroups in the population appear to ignore these signals. A householders' survey analysis of waste designated for recycling proved to be unreliable and difficult to interpret This was caused by the public's general inability to interpret plastic recycling numbers for correct sorting, and to measure volume and weight correctly.
