Directly relating and supporting Sustainable Development Goal (SDG) 12.3, to halve global food waste at consumer and retail levels by 2030. This research was done by analysing appropriate literature exploring food and organic waste management strategies in national and international hospital service sectors and systems, further using the Food Recovery Hierarchy as a framework, which ranks the effects of these strategies when looking at them financially, environmentally and socially. Furthermore, this research looks at the barriers and enablers of the suggested organic waste management strategies. A food waste audit was conducted at Dunedin Public Hospital to assess and quantify the current organic waste within the system. The key questions of this study are: How do we prevent organic waste in the first place (preparation strategies)? What can we do with the organic waste produced to prevent it from going to landfills? What items in the food system are the most wasted? How much Greenhouse gas (GHG) is produced by this organic waste going to landfill? Organic waste produces methane, occupies land mass and has the potential for groundwater contamination. Ten per cent of total global GHG Emissions come from food waste, 22% of which is occurring at the consumption level. The key impact of this research is to mitigate organic waste going to landfills to reduce further climate change, thus benefiting environmentally, socially and economically.\u0000Supervised by: Ray O'Brien & Craig Cliff, Sustainability Office, University of OtagoScholarship funded by: Te Whatau Ora Southern","PeriodicalId":313856,"journal":{"name":"Pūhau ana te rā: Tailwinds","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125785437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This project is helping the University of Otago decrease its impact on the environment by reducing the amount of LPG emissions by 36%. To do this I have found a more sustainable solution to the LPG boiler by choosing electrification instead. Electrification allows us to decrease carbon emissions with the electricity used in New Zealand today which consists of 80% renewable energy sources.The data from previous years showed that consumption of LPG is much greater than what was expected due to a last min change in the building. Thus, my job is to research the best option for an LPG boiler replacement in the Eccles building as now the building has been operating for long enough that it is now known what the changes are, as well as the resources now becoming available for this project to be undertaken.By looking at the requirements of the building, I was able to see which energy sources were appropriate and was able to find the right size energy source that the Eccles building needed to install. I was able to collaborate with the Department of Physics, Sustainability Office and Property services to get the relevant information needed which allowed me to make an informed decision on what the best outcome would be.\u0000The Key impact of this research was to implement new alternative will reduce emissions at Otago University so they can achieve their goal of being net zero by 2030.\u0000Supervised by: Dr Arjan Abeynaike (Physics Department) & Craig Cliff (sustainability Office), Univerity of OtagoScholarship funded by: Te Ngaru Paewhenua scholarship","PeriodicalId":313856,"journal":{"name":"Pūhau ana te rā: Tailwinds","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129220029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a truly sustainable community is active in social and environmental sustainability. To enable social sustainability, having a reliable transport system is fundamental, especially accessible public transport. However, in Dunedin, there is a significant demographic gap in taking public transportation. According to the 2022 student travel survey, 50.1% of Otago University students own a Bee Card (public transport user card). However, 84.2% of students have never taken a bus. This report aims to delve into the transportation needs of Otago University students via the use of persona archetypes and evaluate the current transportation system with student needs and concerns. Through the use of personas, and running them through the Dunedin Bus system, there is an argument that the existing public transport system is not accessible to university students and thus needs a revamp to enable social sustainability within the university student population. University-run shuttles influenced by Penn State and the University of North Dakota and creating a student-friendly bus environment are some proposed changes needed to allow student engagement in the Ōtepoti community.\u0000Supervised by: Ray O'Brien & Craig Cliff, Sustainability Office, University of OtagoScholarship funded by: Otago Regional Council","PeriodicalId":313856,"journal":{"name":"Pūhau ana te rā: Tailwinds","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123620279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With New Zealand investing heavily in the development of green hydrogen, the importance of public perception is only going to grow over the coming years. Using articles from New Zealand’s various online news sources, this talk uses a sociolinguistic framework to investigate the way green hydrogen is represented in New Zealand online media. By analyzing online articles through a combination of media analysis and critical discourse analysis, we can begin to understand the way green hydrogen is being framed within the discursive environment of New Zealand. \u0000New technologies do not enter the public eye as isolated instances of innovation and are instead tied into a complex network of larger discourses, political, economic, historical, scientific, and emotional. Critical discourse analysis allows us to consider how these various contexts relate to both the creation and consumption of media surrounding green hydrogen. Using various linguistic frameworks, such as positioning theory, and capital D discourse theory, articles can be deconstructed and related to the various larger narratives which surround green hydrogen, such as sustainability, economic stability, and energy independence. \u0000Supervised by: Abbi Virens, Centre for Sustainability, Univerisity of Otago","PeriodicalId":313856,"journal":{"name":"Pūhau ana te rā: Tailwinds","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124258591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have suggested that this is because there is a great reliance on private cars with reduced incentive to use public or active transport. This research project looks at the current commuting habits of University of Otago employees and the potential barriers or facilitators surrounding a change in travel mode. This will be done by analyzing relevant academic literature which looks at barriers surrounding public transport use nationally and internationally. Data will also be obtained quantitatively through a survey which is sent to all university staff, and qualitatively through focus groups. The three research questions that this study will be conducted through are: What proportion of university employees use different travel modes and what are the reasons for this? What is the potential for mode shift? What are potential barriers or facilitators? Three major themes came up throughout this study and they relate to the frequency of service, waiting time, and travel time. This research seeks to find out how University of Otago staff could be encouraged or facilitated to use public or zero-emission transport.
