Los residuos sólidos de las industrias de productos hidrobiológicos como lo son las cabezas de los langostinos generan la posibilidad de obtener subproductos como harinas que pueden ser empleados como materia prima para la alimentación de animales debido a que poseen un alto contenido de proteínas, carbohidratos, grasas, pigmentos, minerales, quitina, entre otros, las cuales son atractivas a la hora de la formulación de nuevos productos alimenticios. Con respecto al primer objetivo, concerniente al estudio de mercado, se indagó sobre demanda y oferta del producto, logrando descubrir la insatisfacción del mercado, obteniendo de esta forma la demanda del presente trabajo. Asimismo, el segundo resultado enfocado al diseño de la planta, se instituyó las disposiciones idóneas para alcanzar el rango de producción esperado. Se evaluó y seleccionó la ingeniería requerida para el procesamiento de la harina a partir de las cabezas de langostino. Por último, el tercer resultado consiste en la valoración económica- financiera. Se logró resultados financieros planificados (estados de ganancia y pérdida, flujos de caja y balances en general) apoyados en indicadores como el valor anual neto (VAN) y la tasa de interés de retorno (TIR), por lo cual se logró comprobar si en términos financieros el proyecto es admisible. Relacionando a este proyecto el VAN ascendió a un monto de S/ 3 418 734,36 y el TIR que nos arrojó un 47% respectivamente. / The solid residues of the industries of hydrobiological products such as the heads of prawns, generate the possibility of obtaining by-products as flours that can be used as raw material for feeding animals since they have a high content of proteins, carbohydrates, fats, pigments, minerals, chitin, among others, which are attractive when formulating new food products. For the first objective that is the market study, the demand and supply of the product was investigated, in this way the unsatisfied demand of the market was calculated and thus the demand of the project was obtained. Regarding the second result that is the design of the plant, the necessary guidelines were established to achieve the level of production required, the evaluation and selection of the necessary engineering for the flour process from the shrimp heads. To finalize the third result, which is the economic-financial evaluation, the projected financial results (profit and loss statements, cash flows and balance sheets) were obtained with the help of indicators such as net annual value (NPV) And the Return Rate (IRR), with which it was possible to determine if the project is economically acceptable. In the case of this project, the NPV amounts to a positive amount which is S/ 3 418 734,36 and the TIR, which yielded 47 %, respectively.

Social media has recently become an essential component of our daily modern life, with platforms like Facebook, YouTube, and Twitter serving as popular venues for people to share their opinions on various topics, including sustainable food. The interest in consumer sentiments towards sustainable practices has increased particularly after Covid-2019. This study investigates the attitudes and needs of Swedish consumers regarding sustainable food consumption as reflected in their social media interactions using 4588 comments from Facebook and YouTube. The methodology used are sentiment analysis and topic modelling with VADER and Latent Dirichlet Allocation (LDA) respectively. The results reveal a generally strong positive attitude toward sustainable food. However, the study observes further a decline in positive sentiments over time, indicating changing consumer opinions. The primary topic identified is market challenges, such as high pricing. Furthermore, health concerns and environmental considerations are identified both as important factors influencing the choice of sustainable food. The findings highlight the necessity for policy interventions to enhance the affordability and accessibility of sustainable food, as well as the effective use of social media for raising consumer awareness.

The aim of this study was to explore consumers’ descriptions of sustainable food consumption. The concept of sustainability can be difficult to grasp, but is often defined in terms of three pillars; environment, society and economy. Prior research of sustainable food consumption have often focused on one of the pillars rather than all of them together in relation to consumers understandings of sustainable food consumption. Notwithstanding, previous research have mentioned that in order to fully comprehend sustainability it is essential to take all of the three pillars into consideration. Therefore, this study acknowledged this gap, as it focused on the three pillars of sustainability as a base, and further connected the three pillars to the four food concepts; organic, Fairtrade, sustainable diets and waste, in order to fully understand consumers descriptions of sustainable food consumption. The study was conducted using a qualitative approach, and the data was collected through semi-structured interviews with a sample of students and employees at Linnaeus University in Sweden. The interviewees gave varied and interesting answers, which later were analyzed in comparison to the theory on the subject. With the answers from the interviews it was concluded that environmental and social sustainability were prioritized to economic sustainability among participants. As the participants’ descriptions of sustainable food consumption was varied, and all of the four concepts in relation to three pillars were analyzed, a framework was developed in order to clarify how the consumers describe sustainable food consumption. The study also presents a number of implications for further research as well as managerial implications.  Keywords Sustainable food consumption, consumers description, three pillars of sustainability, economic sustainability, environmental sustainability, social sustainability, organic, Fairtrade, sustainable diets, vegetarian, locally produced, waste reduction, food waste

With a total of 164 community supported agriculture programs (CSA), Vermont is leading the "locavore" movement in the United States, ranked number one in the country with the most CSAs and Food Hubs per capita. ("Locavore Index," 2013) CSAs have a large positive impact on reducing carbon emissions, advancing local economic growth, and promoting healthy lifestyles of consumers. The purpose of this study is to explore the overall experience of individuals in comparison to their current social norm, individual attitudes, identity, and intentions of change, and understand any change overtime in their individual attitude and behavior. Attitude change was measured by conducting pre and post surveys of the Intervale Food Hub UVM student members, as well as regression analysis to understand any possible indicators of chance. The data analysis provided understanding of the impact of the Intervale Food Hub's CSA membership on individuals' attitudes, norms, and identity. Survey questions, based on the theory of planned behavior, inquired about individuals' preferences, skills, and behavioral intentions. Because of the complexity of food and human relations, this data was be supplemented by collecting qualitative data to more richly understand the relationship between individuals and their Intervale Food Hub food shares. The conclusion of this study will advance understanding of one form of community supported-agriculture and its impact on human attitudes. Study findings will also aid the staff of the Intervale Food Hub in understanding their customers and implementing more efficient practices.

Alternative food systems (AFS) projects are designed to address issues of environmental justice, food security and insecurity, community health disparities between the affluent and the poor, and access to healthful foods in distressed urban areas. Past research has questioned the efficacy and long-term viability of such interventions, particularly in distressed primarily Black urban areas. The purpose of this intrinsic case study (ICS) was to understand the ways in which local governmental entities collaborated with each other and with nongovernmental partners to help develop an AFS in South Florida through the creation of a market garden called the PATCH. Critical race theory was the framework for addressing the challenges associated with community health, empowerment, and socioeconomic issues pertaining to AFS. A critical case sampling strategy was employed in order to study the selected site. Transcribed data from interviews with 6 key informants, observational notes, and publicly available document searches were coded using a thematic posteriori strategy and analyzed diagrammatically. Results revealed 4 primary drivers for the effective creation of AFS including collaboration and partnerships, community empowerment, community involvement, and the leadership role of government. The concept of transcommunality played an integral role in how these primary drivers could be applied between local governmental and nongovernmental partners. Knowledge gleaned from these results can inform the development of effective community and culturally specific AFS that can help address the disparities that race and socioeconomic status play in providing access to healthful foods in South Florida, thereby creating the basis for positive social change in distressed urban areas.

To address the negative environmental, political, and social consequences of the dominant, industrialized global food system, communities around the world have developed goals and values underlying a sustainable food system. Conceptualizing food production, distribution, and consumption as systems helps clarify the ways food affects social and natural environments, with the distribution element as the critical juncture where the product reaches the consumer. Urban food systems are a particularly important environment in which to study movements toward sustainability. This paper focuses on the movement for a sustainable food system in Portland, Oregon, with particular focus on the city’s markets for food acquisition – food retail, farmers’ markets, community supported agriculture endeavors, restaurants, food service and distribution companies, institutional purchasing programs, and community gardens, as well as the organizations that support the work of these businesses and programs. Leaders in the field of sustainable food systems are now beginning to operate with a strategy for change that emphasizes incorporating sustainable food products and sustainable food system values into mainstream food markets instead of remaining in niche, alternative markets as has occurred in the past. This notion is supported by economic and social theories including the consumer information model, stakeholder theory, social movement theories of change, and network theories. This paper explores the extent to which Portland food distribution businesses, programs, and organizations attempt to fulfill the goals of a sustainable food system movement with moving from niche to mainstream in mind. The fact that the movement is in fact acting according to new strategies for change emphasizing the mainstream is indicated by the movement’s extensive consumer education and creative use of marketing, strong social and business networks, and organized local policy influences.

Visualizations, web technologies and mobile devices are subjects which are trending nowadays in the world of technology and many research projects are tackling different issues. The originality of the thesis is in the aspect of bringing all these mentioned subjects together and providing findings that will help web designers when implementing visualizations for mobile phones. The thesis explores the use of web technologies for the visualization of complex data for mobile devices, both looking at the technical state of the art and capabilities, and at the difference in information needs for users in a mobile usage context. The first part deals with an in-depth research of the existing projects that deal with similar issues, analyzing the official documentation of the technologies and the community of developers. The other part of the research is focused on providing insights on the required changes for adapting to the needs of mobile device users by doing a usability testing on a specific visualization. The results provide information valuable for adapting visualizations, such as font sizes, color combinations, animation complexity and data simplicity. The use case that is used for feeding the visualizations with data belongs to the domain of eco visualizations, in particular dealing with sustainable food consumption.

The purpose of this thesis is to explore if consumers evaluate CSR more into their purchase criterion compared to before the Covid-19 pandemic. CSR activities, consumer buying behavior, and CSR as a purchase criterion were combined in a conceptual framework. The consumer decision-making model was used as a framework in consumer buying behavior. In CSR as a purchase criterion, three factors were used to conclude if consumers started to evaluate CSR more as a purchase criterion. The empirical data was collected through two semi-structured focus groups. Group A was ensembled through a convenience sampling method but evolved to a snowball effect. Group B was ensembled through a purposive sampling method. The findings indicated that consumers did not start to evaluate CSR more as a purchase criterion. The main reason was the financial situation. However, consumers have started to buy more sustainable food, especially locally produced during the pandemic which indicated an increased awareness towards CSR as a purchase criterion. The findings also showed that the Covid-19 pandemic influenced consumers' awareness of CSR but the implemented safety precautions in grocery stores had a limited effect on consumers. The research field of consumer buying behavior in the context of CSR can be complemented with the findings in this study. This study contributed to a deeper understanding of consumer buying behavior and if they value CSR in their purchases during the Covid-19 pandemic.

Today communication on social media takes place with a wide reach and from several different sources. This has made it more difficult for the user to perceive credibility than before. A current issue today is how we should consume food more sustainably because both humans and the environment are threatened. The study examined how the various components of credibility are perceived by a specific type of user on Youtube. The purpose was to contribute with an understanding of the extent to which a user with knowledge about sustainability perceives Youtube content about sustainable food as credible. Furthermore, the study aimed to highlight credibility in communication about sustainable food. The study applied a qualitative research method with collected empirical data from six semi-structured interviews. The Source of Credibility Model was used as a theoretical framework to contribute the study to investigate the dimensions within the perceived credibility from the user's perspective. Results of the study display that the perceived credibility of Youtube content are affected by various factors and that they can have an individual impact on the user. Honest, realistic, and relatable content enhances credibility. Furthermore, content based on facts and content from a person with experience are factors that increase credibility as well. The user's perceived credibility is also based on the person speaking in the video. In communication about sustainable food, credibility is increased if content comes from a relevant Youtube channel. / Idag når content på sociala medier ut till en bredare massa än tidigare och från flera olika avsändare. Det har lett till att användaren upplever svårigheter med att bedöma information som trovärdigt eller inte. En aktuell fråga idag är hur vi skall konsumera mat mer hållbart eftersom både människans och planetens miljö är hotad. Studien undersökte hur en specifik användare upplever content på Youtube sätt till trovärdighet. Syftet var att bidra med förståelse hur trovärdigt användare med kunskap inom hållbarhet upplever content om hållbar mat på Youtube. Vidare syftade studien till att belysa trovärdighet inom kommunikation om hållbar mat. Studien tillämpade en kvalitativ forskningsmetod med insamlad empiri från sex semistrukturerade intervjuer. The Source of Credibility Model användes som teoretiskt ramverk för att bidra till undersökning av faktorerna inom den upplevda trovärdigheten utifrån användarens perspektiv. Utifrån analys och diskussion av studiens resultat drogs slutsatserna att den upplevda trovärdigheten av Youtube content påverkas av olika faktorer och flera av dem kan ha en individuell påverkan för användaren. Vidare förhöjer ärligt, realistiskt och content som går att relatera till trovärdigheten. Ytterligare är faktabaserat content samt content från en person med erfarenhet faktorer som förhöjer trovärdigheten. Användarens upplevda trovärdighet är inte endast baserat på informationen i sig utan även på personen som talar i videon. I trovärdig kommunikation om hållbar mat förhöjs trovärdigheten om content kommer från en Youtubekanal med relevant inriktning.

Food production has been shown to have considerable negative impacts on the environment. A means to reduce this is to choose organic products when shopping for food. Through the case of the EcoPanel, a web application prototype that visualises the organic proportion of the household’s food shopping, the thesis explores the intersection between design, reflection and sustainable food shopping practices. In order to contextualise the role of the EcoPanel, the text discusses the concept of food shopping practice, both from the perspective of social practice theory (SPT), and the more focused food choice perspective. The studies show that it is fundamental to understand the complexity of choosing food, and the habitual aspect of practice, in order to understand the role of reflection in food shopping practice, and consequently the role of a tool for reflective decision-making, like the EcoPanel. We have used a research through design approach to develop the EcoPanel prototype. In an iterative process we probed how the EcoPanel could be designed to be as relevant and accessible for the users as possible. Essential in the process were the iterative user feedback sessions. The way in which the users answered the questions from the sessions formed the guiding principles for the development of the design. A central question in the thesis is to explore in what ways the users’ access to their individual sustainable grocery data provided by the EcoPanel affects their food shopping practices. The studies include monitoring sixty-five users of the EcoPanel over five months, a survey regarding aspects of lifestyle and attitudes to food, and interviews with ten of the users. The long-term study shows an increased organic purchase level (17%) for the EcoPanel users in comparison to the reference group. We also see that when the users receive feedback on their organic food purchases through the EcoPanel, they can make more reflective decisions. This is shown to be highly relevant and creates meaning for the users in several different ways. From this result, in combination with the result of the long-term study, we can conclude that the EcoPanel contributes with support for more sustainable food practices. The last question in the thesis is to understand how SPT can be useful for design practice. SPT shows a view that goes beyond the traditional interaction perspective, and points to the importance of approaching complex issues, such as sustainability challenges, with an awareness that also includes social and cultural aspects of the context. As well as this view being pertinent when approaching sustainability issues, it also provides value to designers in their emerging roles of dealing with more socially embedded concerns, such as social innovation and design for public policies. / <p>QC 20160311</p>
