Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Odlingsstrategier på organogena jordar : en studie om beslutsfattande bland KRAV-anslutna lantbrukare
This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.
Samband mellan anknytning och självkänsla hos ungdomar. En pilotstudie
Background:When the patient is critically ill the family is in a vulnerable position. The nurse's role is to support and help the family to find meaning in the difficult situation and to provide realistic hope. Balancing between the patient's and the family's needs is difficult. Knowledge about how nurses experience difficulties in the interaction with family is required in order to grant good care too critically ill patients and their family-members.Aim:To describe nurses' perceived difficulties in the interaction with family-members of critically ill patients.Method:The study is a qualitative literature-based study based on qualitative research. Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.
Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Hållbar utveckling: Hjärtefråga eller nödvändigt ont? ? Miljöarbete hossvenska SME-företag i konfektionsbranschen.
The aim of this thesis is to give an insight to how work is being pursued within Swedish SMEin the clothing industry. Furthermore we investigate how efforts can proceed withenvironmental questions in a quest for sustainable development and bring clarity in thedifficulties that occur. Through the use of company examples and a description of how theywork we wanted to give stakeholders knowledge in what resources and procedures that areused today on the market. The function of the report is moreover to provide Swedish smalland medium-sized clothing enterprises suggestions and directions of how to advance withinsustainable development.In our theoretical frame we have chosen to administer the theories that we found suitable forour study. Seen from a perspective of sustainability we have thus applied the theories ofstakeholder and legitimacy, an analysis model for a company?s actions in environmentalquestions and the theory of SME which describes a small or middle sized enterprise?s fivecompetitive variables.The empirical frame we acquired for this thesis is presented in three chapters.
Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt
ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
Livsstilar kommer och går, men valen består?
ABSTRACTTitle: ?Lifestyles come and go but your choices remain?? (?Livsstilar kommer och går, men valen består...?)Number of Pages: 42 (45 including enclosures)Author: Jenny RydqvistTutor: Göran SvenssonCourse: Media- and Communication Studies CPeriod: Autumn term 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The aim of this essay is to make a study of how young adults between 19-25 years are influenced by commercials.Key Questions: How are students in Uppsala influenced by commercials? Do the commercials influence the consumptionbehaviour? Do the commercials influence the lifestyle? Do the influences of the commercial construct the individual lifestyle? In which extent is it social related?Material/Method: Together with literature studies, a qualitative method has been used with 5 interviews with young adults in the age of 19-25 in Uppsala. I have compared these five interviews with earlier results and research.Main Results: I have found out that these young adults don?t want to admit being influenced by commercials even if they know they are. These young adults have also formed consumptionbehaviour after the commercials, which they show in for example their way of shopping and their way of acting afterwards.
Hållbar avfallshantering : Ur ett ekonomiskt- och miljöperspektiv
Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.
Engagerade ungdomar : en hållbar energistrategi
The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a).
The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.
Politiskt organisationsbyggande : Om ungdomars inflytande i Rädda Barnen
?Have the young members? of Save the Children Sweden got increased possibilities to influence the organization since the founding of the youth-organization?? The purpose with the thesis is to investigate if the founding of a youth-organization by Save the Children Sweden has led to increased possibility for the young members to influence the organization. I have two research assignments; change since the founding of a youth-organization? politically since the foundation of a youth-organization and how?Did the norms and values in the organizationand Did the organization change I have analyzed protocols from the general assembly between 1997 and 2008 and how the rules in the organization have changed over time. I have also interviewed four board members to get a more diversified view of how the board meetings proceed.
En strategisk planeringsmodell: Att införa medborgarkontor i ett folkbibliotek med hjälp av strategisk planering
This Masters thesis is concerned with the complex planning process of setting up a citizen bureau in a public library. The aim is to find out how citizen bureaux are designed and to suggest a simplified model of strategic planning. The planning process is studied from a business perspective in the library context, and this perspective is also used to study citizen bureaux and their written plans elsewhere. A combination of qualitative methods are used: observations, focus group discussions and interviews. Observations in the public library showed a great need for an environmental analysis as well as structure to the planning process.
Bibliotek och bokhandel som litteraturförmedlare: En användarundersökning på ett bibliotek och i en bokhandel
The purpose of this study is to examine what readers of fiction literature are influenced by when they choose books. What libraries and bookstores do to influence readers in their choice of literature and how readers perceive the librarys and the bookstores influence on them in their choice of fiction literature. We have also studied which factors outside the library and the bookstore that readers are influenced by when borrowing or buying a certain book and to what extent readers are influenced by the books appearance. To answer our questions we chose a public library and a bookstore, where we interviewed six persons in each place. We have interviewed a librarian and a bookstore manager for information about how these two cultural institutions work with marketing of their fiction literature.
Produktkvalitet på svenskt nötkött : en kartläggning av kvalitetsfaktorer inom IP Sigill
Sigill Quality Systems has been certifying beef since the autumn of 2006 using the brand
name label Swedish Sigill. IP Sigill (the certifying system for integrated production)
encompasses the values: animal ethics, food safety, free range and environmental concerns. Product quality is not yet one of these values, and there is a variation in the quality of Swedish beef. Swedish Sigill wanted to investigate the factors that influence product quality, review which of the present regulations that have an influence on product quality and formulate new regulations with the purpose of enhancing the product quality (sensorial, technological and nutritional quality).
A survey of quality parameters and factors that influence product quality was done in order to establish a scientific foundation to work from.
Etisk Shopping : En studie av unga mäns tankar kring etiska dimensioner av klädkonsumtion
In contemporary public debate there is currently a great deal of focus attached to environmental problems and social responsibility. This trend is noticeable within the clothing industry, where it has become increasingly popular for new brands to market themselves with an environmental and ethical profile. An anthropological approach has been used to investigate how individuals understand ethical dimensions of clothing, and relates to the consumers? ideals that are pronounced by clothing companies with an environmental and ethical profile. Interviews have been conducted with young men, a group often absent in accounts of ethical consumption.
