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.

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.

Vem tar ansvar? : En kvantitativ innehållsanalys av hållbar utveckling i läroböcker för fysik A och Fysik 1

För att åstadkomma en hållbar utveckling lyfts utbildning, av internationella policydokument för en hållbar utveckling, fram som mänsklighetens bästa hopp och mest effektiva medel[1]. Därför intresserar denna studie sig för hur svensk skola tar ansvar för att den potential som utbildning bär på skall utnyttjas. Studieobjektet i denna studie är läroböcker för den inledande fysikkursen på svenska gymnasieskolan, fysik A eller fysik 1. Vidare har undersökningen, med stöd i forskning om undervisning för hållbar utveckling, avgränsats ytterligare genom att endast rikta sig mot de uppgifter som finns i böckerna. Metoden som använts är en kvantitativ innehållsanalys där frågor om någon, och i så fall vilka, aspekter av hållbar utveckling och vilka kunskapsemfaser som betonas har ställts till böckernas samtliga uppgifter.

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.

Hållbart ansvarstagande för ett medelstort byggföretag i Sverige - En analys av värdeskapande aktiviteter som bidrar till hållbar utveckling.

This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.

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..

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.

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.

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.

Interviews have been conducted with young men, a group often absent in accounts of ethical consumption.

Det kan vara farligt att ligga lågt - om stadsplanering inför stigande vattennivåer : Exempel från Göteborg, Kristianstad och Arvika

In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.

Beräkning av massbalanser för metaller i vatten samt miljöriskbedömning av Nerån vid Österbyverken i Östhammars kommun
