Food Waste Innovation people

Food Waste Innovation researchers measure food waste, develop reduction strategies, apply innovative technology, and work to modify producer and consumer behaviour.

Steering Committee

Associate Professor Miranda Mirosa

Department of Food Science

Miranda Mirosa image Associate Professor Miranda Mirosa is Director of Food Waste Innovation, and research leader of the Social Innovations sub-theme.

Miranda’s behavioural research engages knowledge from fields such as marketing and psychology to provide insights and interventions for improved food system sustainability. Her research creates evidence-based solutions to help change peoples’ behaviours (i.e. identify the barriers to achieving a desired activity, design a behaviour change intervention or strategy to overcome the barriers, and pilot the interventions / strategies before broad implementation).

She provides academic consultancy services on food waste to government and businesses and is the author of the Mirosa Report, written for the Parliamentary Environmental Committee who ran a targeted briefing on food waste in NZ, which looks at the current status of food waste in Aotearoa and provides recommendations for action.

She is Co-Chair of the New Zealand Champions 12.3 initiative, a coalition of Champions from our food supply chain who are committed to halving food waste by 2030 and achieving Sustainable Development Goal (SDG) Target 12.3.

Professor Sheila Skeaff

Department of Human Nutrition

Sheila Skeaff imageProfessor Sheila Skeaff is research leader for the Metrics and management sub-theme.

Professor Skeaff's work on waste aims to understand the volume and nature of food being thrown away. Obtaining baseline data, along the food supply chain, are needed to inform food waste prevention strategies that make the biggest impact with the least resources. By using robust, internationally recognised methodology to quantify food waste, the success of these strategies can be evaluated and improved. Her measurement work to date covers a range of sectors including post-harvest and retail.

Exploring barriers to sustainable household food waste practices, MPlan Candidate

My research examines the barriers that exist that prevent households in Dunedin’s tertiary precinct from both minimising and diverting their food waste from the waste stream. The study incorporates considerations of how the built environment plays a role and will offer recommendations on how city planning can help address the issue of food waste in Dunedin.

Impact of COVID-19 on the food recovery sector, BScHons Candidate

I am interviewing people working in New Zealand’s food rescue sector to learn about the challenges and opportunities that COVID-19 posed for their organisations. From these experiences, I aim to provide a framework for sharing these learnings that will strengthen the sector’s ability to prepare and respond to future crises or disruptions to the food supply chain.

The metrics and management of food and plastic waste associated with online food delivery in China, PhD Candidate

My research focuses on a rapidly developing issue in the supply chain – waste associated with the online food delivery sector. The primary purpose of this research is to provide an understanding the type and volume of food and packaging waste produced and to devise and trial interventions to enhance the sustainability of this sector. I will do this by (1) qualitatively understanding Chinese consumers’ perceptions and practices relating to online food delivery and its associated waste; (2) quantifying the volume and types of consumer-level food and plastic waste associated with online food delivery in China; and (3) measuring the effectiveness of interventions designed to reduce food and packaging associated with online food delivery.

Socialisations of norms about perceived edibility of suboptimal foods, PhD Candidate

My research explored suboptimal produce consumption, purchase, and preference from the perspectives of children, thereby also casting light on how these preferences are socialised. The findings inform retailing practices for marketing and selling suboptimal produce. The research also influences how policy makers could implement normalisation strategies for increasing the acceptance of suboptimal produce.

Cost Effectiveness and Social Accountability of Waste Management System of the Supermarkets in New Zealand, PhD Candidate

Globally plastic packaging and food waste have become a substantial problem. The main objective of my research is to identify the food and plastic packaging waste control system introduced by the major supermarkets chain in New Zealand and access the cost effectiveness and social accountability of those system. Along with the main purpose, this study focuses the solid waste reduction strategies that have already implemented or plan to implement in the near future. Moreover, what are their approaches to convert into the circular economy in 2025 with zero plastic waste. Furthermore, identify the key motivations and barriers to food waste reduction in this sector.

Measuring and exploring the drivers for food loss in the horticulture sector, MSc Candidate

I have worked as a dietitian for over twenty years, predominantly with the hospitality sector and other organisations within the food supply chain. I have a passion for supporting a nutritious, sustainable food supply. The implementation of a food waste monitoring programme and the development of a plate waste reduction campaign sparked my interest in reducing food waste.

I am currently completing a Master of Science measuring and exploring the drivers for food loss in the horticulture sector. I enjoy being hands on as a volunteer for a food rescue organisation, helping to redirect surplus food to those in need. I am also a member of the Coeliac NZ Medical Advisory Panel with a particular interest in supporting their Dining Out programme.

Smart (i.e. active, intelligent) packaging to reduce food waste, PhD Candidate

Smart packaging technologies have the ability to improve food safety and quality outcomes for New Zealand food exports, through improving the protection and communication functions of the packaging. However, little is known about how Chinese consumers perceive packaging in general as an influencer in food choice, let alone innovative smart packaging technologies. China is New Zealand’s biggest export partner and offers significant opportunities. So, understanding Chinese consumer perceptions of smart packaging, and what types of smart packaging are preferred allows the New Zealand food and beverage industry to focus their packaging innovation efforts on the product and technology combinations that provide the best advantage in the Chinese market.
