The process of organizational change in Food Waste Management in the Food and Beverage production industry in Thailand:  From the lens of loop learning

Berne, Tiffany C., Zekaria, Sheyima Zeidan January 2023 (has links)
Thailand is called the kitchen of the world; the country produces food and beverage products and exports around the globe. According to previous studies, there is not enough data on food waste in Thailand and worldwide. This study aims to analyse the characteristic of the loop of learning in assisting the process of organizational change and explain how it can support sustainable change in Food Waste Management. Even though a loop of learning is used frequently to develop changes in organizations, the relationship between organisational learning methods and organisational change is still not yet identified.  The qualitative method, particularly a case study, was used to accomplish the aim. The case study focuses on how production companies develop their organisational change toward sustainable Food Waste Management in Thailand by aligning the management's thinking level with a loop of learning. The data collection method is a semi-structured interview with 12 managers of different food and beverage manufacturing companies. The results show that current actions are 1) following the existing regulation and finding solutions for challenges, 2) developing better methods and re-using waste, and 3) setting new strategies to achieve sustainable Food Waste Management. Thus, those actions have the quality of single, double and triple-loop learning.  Furthermore, the research findings indicate that changing norms with environmental concerns can influence other factors, such as laws and stakeholder expectations. The organizational change process must involve continually thinking in the loop of learning from an individual and organisational perspective. These authors conclude that the nature of loop learning is a process that individuals and organizations can use to identify and reclaim problems; this process assists organization to realise the need for changes and continue developing solutions for those matters. The outcomes of continuous thinking will present changes in action which reach organisational change.

Re-defining data visuals for an efficient and sustainable food waste management

Singh, Suhas January 2017 (has links)
The use of visual data representation is increasing the possibilities to exchange information and communicate indifferent contexts all over the world. Communicating food wastage visually to influence consuming patterns isone of these possibilities. Food wastage is currently a much-prioritized topic in Sweden as well as globally due toits negative impacts on society, environment and the economy, and therefore there is much need to bringinnovative solutions supporting reduction of food waste. This thesis presents a qualitative research based on a casestudy of food waste management at Sala municipality in Sweden while exploring the current visual datarepresentation techniques and its further potential to make food waste management more sustainable. The researchframework used in this thesis is based on visual rhetoric and the innovation theories. The thesis analyzes foodwastage from an international perspective, its connection to sustainable development goals and how MatomaticAB uses a visual data representation tool to address food wastage.The thesis further explains how the users associated with Sala municipality interpret the existing tool, thechallenges they face and review their expectations to build a new visual data representation model. The results ofquestionnaires filled by user’s, state that 50% of the respondents understand the current tool to its full capacityand only 50% of the respondents are satisfied with the overall tool. When it comes to the choice of datapresentation 67% of the users showed interest in use of infographics instead of the conventional bar graphs, andtherefore some parameters like, making the tool more interesting using infographics, user friendly by limiting thedata displayed and interactive by giving user options to explore further as per their liking, were thought whiledesigning the new visual data representation model.

Food Waste Management - Perceptions, Decisions, and Actions: The case of Guatemala City Department Restaurants

Monzon Santos, Juan Luis Andre January 2017 (has links)
Food waste has implications for the people, the planet, and profits. It presents a global problem which normally requires a local solution. Around 6% of the global food loss occurs in Latin America. However, the region lacks a clear strategy to address the issue, which is also true at the national level for countries such as Guatemala. Furthermore, the perception of different actors in the country towards food waste and its management remains unknown. The aim of this research is to explore on the attitudes towards food waste that might exist in the country by focusing on the restaurant sector with the objective of producing a holistic understanding of the issue. Concentration on the restaurant sector provides additional information of the matter, on a sector that shows limited research on it. To fulfill this objective, a case study was conducted, one that involved the participation of three actors directly related to restaurants as either managers or owners and an actor involved in the Municipality of Guatemala City. The research utilized semi-structured interviews and a review of the literature available on the subject as means of data gathering. The analysis was supported using the Triple Bottom Line Framework, a Positional Analysis ideology, the Sustainable Development Goals and the EU Waste Framework Directive. The results showed varied perceptions from the actors on the categorization of food waste, although impacts on an economic, environmental, and social dimension derived from food waste were acknowledged by all of them; being the latter the most prominent. For the actors, the generation of food waste was significant at the customer level, but was also influenced by the type of service provided by the restaurants. Additionally, the approaches selected by them to either directly or indirectly manage food waste covered a vast range of actions. Finally, the actors understood as key for addressing the food waste issue, the raising of awareness on the subject.

Environmental education through sustainable school food waste management in the Vhembe District, Limpopo

Maphaha, Matodzi Hellen 08 August 2020 (has links)
This qualitative case study focuses on identifying factors that could either enable or constrain sustainable food waste management as a form of environmental education (EE) in the participating schools. The study was motivated by the observation that the National School Nutrition Program (NSNP) that was introduced by the Department of Basic Education to support learners from disadvantaged backgrounds with nutritious food was causing pollution in some schools due to inadequate discarding of food leftovers. The purpose of the study was to develop recommendations towards a sustainable means of managing this food waste in the schools. As an Agricultural Science educator, I wanted to explore the possibilities of enhancing environmental education in schools through sustainable food waste management. While research has been conducted about food waste management and how this is an environmental concern, little has been written about it as it relates to environmental education and sustainability in schools. Hence, this study sought to contribute knowledge to this gap. To achieve this aim, this study followed a descriptive case study design, framed by the value-belief-norm (VBN) theory. Three schools in Vhembe district, Limpopo, were conveniently selected, and the NSNP food coordinator of each selected school, one food handler, two learners, two educators and two SGB members from each sampled school were purposively sampled to get rich information from them about sustainable school food waste management. Data were collected through semi-structured, face-to-face interviews and observations. The findings indicate the various ways in which food waste could be managed in these schools, such as recycling through composting, reusing by community farmers, and reducing the amount of possible food waste. The study also found environmental education to be a key element in which the schools could invest to sustainably and effectively manage food waste. / Educational Studies / M. Ed.

Ecological food sense : connections between food waste flows and food production in Enkanini Informal Settlement, Stellenbosch

Mollatt, Michelle Claire 04 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2014 / ENGLISH ABSTRACT: In situ Informal Settlement Upgrading (ISU) was explored in this thesis, focussing on its relevance to waste service upgrading options immediately available and practically implementable for residents of Enkanini, a poorly serviced township (slum) in Stellenbosch, South Africa. Household food waste (kitchen scraps) was chosen as a key point of entry for exploring the context and viability of in situ improvement of solid waste management services in the area. This was done by investigating ways biological and social aspects of soil quality and food waste management can be incrementally improved in the settlement. Transdisciplinary methodology, Participatory Action Learning and Social Learning perspectives, combined with ecological thinking were used to explore different methods of managing food waste in Enkanini. A food waste collection pilot project was initiated in Enkanini by the Stellenbosch Municipality in 2012. The project was modified and continued in 2013, which served as the case study for this thesis. In 2013, food waste was collected by 56 households over five months. It was treated with Bokashi Effective Micro-organisms (Bokashi EM) containing yeasts, lactic acid bacteria, actinomycetes and photosynthetic bacteria. The Bokashi EM partially fermented the waste before it was used for composting or feeding to Black Soldier Fly (Hermetia illucens) larvae. Laboratory testing of food waste, compost, soils and larvae waste residue determined the safety, potential and sustainability of food waste for recycling and contribution to local urban agriculture by closing the organic waste loop, and for generating an income stream. A total of 5851kg food waste was collected, saving 6m3 landfill space. Households generated 5,2kg - 9,6kg food waste per week. Extrapolating this lower figure for all of Enkanini (about 2400 households), about 50,2 tonnes of food waste could be generated per month. If this were collected and recycled or composted, this would save 51,2m3 landfill space per month. The most commonly cited benefit of food waste collections by participants was reduction of vermin in or around their homes. Laboratory testing indicated that some samples had high levels of Escherichia coli (E. coli) bacteria. No traces of Salmonella were found in food waste, compost and soil samples, and most were within acceptable limits for heavy metals. It was cautioned that vegetables grown on soils or compost with high E. coli be washed or cooked before consumption. Following socially and ecologically sustainable management of Enkanini’s food waste requires a combination of waste management methods. Options include localised composting - burying EM treated food waste in soil; in situ container composting of waste and adding this to soil; processing of EM treated food waste by Black Soldier Fly larvae (and their subsequent use as feed for chickens or fish); and finally by anaerobic digestion for generation of biogas and effluent fertiliser in local biodigestors. The thesis showed that biological elements (such as bacteria and soil nutrients) have impacts on residents in communities and these need to be considered significant. The thesis suggests ecological elements be considered as indicators or building blocks for ISU locally, nationally and internationally. Keywords: in situ incremental upgrading, food waste management, Effective Micro-organisms, social learning, urban agriculture, closed-loop systems, organic waste management, informal settlements. / AFRIKAANSE OPSOMMING: In situ Opgraderingsprojek vir Informele Nedersetting (OIN) is in hierdie tesis ondersoek, met die fokus om die relevansie van afval diens opgradering opsies prakties te implementeer vir die inwoners van Enkanini, Stellenbosch, Suid Afrika, 'n gemeenskap met swak dienslewering. Huishoudelike kombuis voedselafval is gekies om die konteks en lewensvatbaarheid van in situ verbetering van vaste afval bestuur dienste te ondersoek. Dit is bereik deur maniere te ondersoek om die biologiese en sosiale aspekte van die kwaliteit van grond en voedselafval bestuur in die nedersetting te verbeter. Transdissiplinêre metode, Deelnemende Aksie Leer en Sosiale Leerprosesse, gekombineer met ekologiese denke, is gebruik is om verskillende metodes van die bestuur van voedselafval in Enkanini te verken. 'N Enkanini voedselafval versamelingsprojek is in 2012 deur die Stellenbosch Munisipaliteit begin. Dit is in 2013 aangepas en vir hierdie studie gebruik. Gedurende vyf maande in 2013 is voedselafval deur 56 huishoudings ingesamel. Dit is behandel met Bokashi effektiewe mikro-organismes (EM Bokashi) met gis, melksuur bakterieë, aktinomisete en fotosintetiese bakterieë. Die Bokashi EM het die afval gedeeltelik gegis voordat die afval gebruik was vir kompos of voeding aan Swart Soldaat Vlieg (Hermetia illucens) larwes. Voedselafval, kompos, grond en larwe oorskot laboratourim toetse het die veiligheid bepaal, asook die potensiaal en volhoubaarheid van die afval vir herwinning en die bydrae tot die plaaslike stedelike landbou deur middel van die organiese afval siklus, en vir inkomste generering. 5851kg voedselafval is ingesamel en 6m³ se opvullingsruimte bespaar. Die huishoudings het 5,2kg – 9,6kg voedselafval per week gegenereer. Die laer syfer in aggeneem, kan sowat 50,2 ton voedsalafval per maand in Enkanini (ongeveer 2400 huishoudings) gegenereer word. As dit ingesamel, herwin of gekomposteer was, sou 51,2 m³ opvullingsruimte per maand bespaar word. Die belangrikste voordeel van die voedselafval versamelings was die vermindering van knaag en aasdiere rondom wonings. Laboratoriumtoetse het hoë vlakke van Escherichia coli (E. coli) bakterieë in sommige monsters gevind. Geen spore van Salmonella is in die voedselafval, kompos en grondmonsters gevind nie en meeste was binne die aanvaarbare perke vir swaar metale. Die gemeenskap is gewaarsku om groente wat in die grond of kompos gekweek is voor verbruik in chloorwater te was of kook. Die sosiale en ekologies volhoubare bestuur van Enkanini se voedselafval vereis 'n kombinasie van afval bestuursmetodes. Opsies sluit gelokaliseerde kompos - begrawe EM behandelde voedsel afval in die grond; in situ houer kompos afval en die toevoeging van hierdie tot die grond; verwerking van EM behandelde voedselafval deur Swart Soldaat Vlieg larwes (en hul daaropvolgende gebruik as voer vir hoenders of vis); en uiteindelik deur mestvergisting vir die generasie van biogas en kunsmis in biovergisters. Die tesis toon dat biologiese elemente (soos bakterieë en voedingstowwe in grond)'n impak het op die gemeenskap se inwoners en as n belangrik faktor beskou moet word. Die tesis dui ekologiese elemente as n toekomstige aanwysers aan indien OIN plaaslik, nasionaal of internasionaal oorweeg word. Sleutelwoorde: in situ toenemende opgradering, kos afval bestuur, effektiewe mikro-organismes, sosiale leerproses, stedelike landbou, geslotestelsel-sisteme, organiese afval, informele nedersettings.

Food corporations and government rethinking food waste strategies in Johannesburg City

Pheto, Bokang January 2018 (has links)
Global nations are awakening to the realisation and manifestation of actual food insecurity. Voices which advocate for food security have always been there but were overshadowed by corporate ignorance and overpopulation. Corporate food waste plays a major role in contributing to food insecurity although the spotlight is hardly put on them. As the economic hub of South Africa, the City of Johannesburg (CoJ) must take the lead in rethinking food waste reduction strategies in food corporations selling fruits and vegetables where the most waste occurs in the country. The level of fruit and vegetable wastage should decline in order to counter the adverse effects of food waste. The aim of this study is to establish strategic ways to decrease fruit and vegetable wastage at corporate level in the CoJ. This is achieved by determining contributing factors to food waste including improving food waste reduction models with the intervention and collaboration of food and wholesale stores as well as government. Face-to-face interviews, online surveys and a case study were methods used to answer the study objective. Responses from the field work show that many fruit and vegetable customers opt for conventional or ‘ordinary’ looking foods than ‘wonky’ looking ones. Also, many of the food stores do not have food waste reduction models to guide them, leading to a lot of food being dumped. Furthermore, the food health and safety criteria seem to be a leading contributor to food waste. These results indicate that food waste reduction is also important at pre-consumer stages. On this basis, it is recommended that a solid partnership between food corporations and Johannesburg city is formed in solidarity against food waste. Serious measures must be put in place in order to minimise fruit and vegetable wastage on both sides. These changes have potential to have an immense impact on the economy, environment and society. Further research should be undertaken to identify other factors that could be helpful in the quest to limit food waste in food corporations. / Development Studies / M.A. (Development Studies)
