Uppvärmning och miljöpåverkan : -en jämförelse mellan fjärrvärme och bergvärme i villa
Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..
Att måla läppstift på grisen: En fallstudie om den interna interaktionen mellan Inköp och Miljö i arbetet mot hållbar utveckling
During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.
Arboga Mekaniska Verkstad : Förslag på saneringsåtgärder gällande gjuteriet och plåtverkstaden
The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.
En socialpsykologisk studie om personers upplevelser av Rehabvistelsen Första Steget på Kurorten i Varberg
The purpose with our research in Varbergs Kurort is to study how persons that have been a part of the individual adjusted rehabilitation program First Step have found their stay during their program. The program holds a team of professionals that together work with the individual?s physical and mental health. In our study we have included eight women and to men in the age between 35-65 years who all suffered from a slight mentally illness. Out of a social psychological perspective we have based our study from the social and room environment and how their self-recovery has affected their wellbeing during their rehabilitation.
Att fråga eller inte fråga, det är frågan : En studie av frågor mellan lärare och elever under kemilektioner
This report presents the use of questions by both teachers and students in chemistry class. Both students and teachers have been observed during 24 lessons, both theoretical and practical. In addition, interviews have been made with the teachers and the students have answered a questionnaire. The result show that a high number of questions are asked, more than one per minute and that both teachers and students ask the same amount of questions. This contradicts earlier findings were teachers questions dominate.
Svenska miljömål på byggprogrammet? - Ett sätt att integrera hållbar utveckling i karaktärsämnet
Syftet har varit att undersöka om de Svenska miljömålen kan vara ett sätt att göra hållbar utveckling synlig för elever på byggprogrammet. Det har också varit att ta reda på vilka mervärden som kan skapas genom att hållbar utveckling synliggörs genom att miljömål integreras i undervisningen. Delmålen är verklighetsnära och direkt kopplade till byggbranschen, vilket kan medföra ett ökat engagemang och vilja till att medverka till förändring.Resultatet visar att yrkeslärare, elever och platschefer på byggföretag inte hade kännedom om miljömålen. Svenska miljömål behöver integreras i karaktärsämnena på byggprogrammet för att politiskt fattade beslut om vad som krävs för att vi ska kunna nå hållbar utveckling förmedlas till de elever som skall ut i yrkeslivet, så att de kan komma ut med en handlingskompetens som kan leda till förändring. Nästan samtliga var överrens om att det skulle kunna ge mervärden att ha kunskap om hur de i sin vardag kan arbeta med hållbar utveckling.
Detaljhänsyn efter slutavverkning : kvantitet och inverkan på framtida produktion hos SCA i Västerbotten
According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.
Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik
Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water.
Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.
På jakt efter miljörörelsens sångtradition
Is there a specific tradition of songs within the swedish environmental movement? What kinds of music has been performed in different situations and what does it mean to the movement and its inner life? The essay deals with a town meeting and action against plans of establishing passenger flights at a former military airport in Uppsala, looking at the action as a performance and as a ritual. The second part of the essay is built on interviews of three veterans of the movement's organisations one of which is as a singer-songwriter originally active in the peace movement of the 60's. The paper is about the songs and the situations in which they were sung, concluding that there is, the limited material considered, little evidence of considerable transfer of songs within the movement, though some coherence exists. The connection to between environmental movement and the swedish radical music movement of the 70's is also slightly mentioned.
Växjö - "Europas grönaste stad" : En undersökning av motiveringarna bakom en "grön" kommuns miljösatsningar

The aim of the essay is to be theory-testing as to see how a municipality/city which promotes itself as being ?green? motivates its efforts in the environmental area. Växjö city promotes itself as ?The greenest city in Europe?, an award appointed to the city by BBC and other international media.
Anställningsintervjun och dess personbedömningsmetoder en jämförelse mellan internrekryterare och rekryteringskonsulter
The employment interview is an important part of the recruitment process because the recruiter then has a chance to form an opinion about the applicant as a person. The purpose with this study has been to examine if there are any differences between inhouse-recruiters and recruiting consultants concerning the employment interview and its assessment methods. Five inhouse-recruiters and five recruiting consultants have been interviewed on the basis of a manual. There are differences between the groups in 6 of the 17 themes that have been examined: purpose with the employment interview, private-, double- or panelinterview, length of the interview, personal chemistry, appearance and objectivity in the assessment. Many of the differences are caused by the fact that inhouse-recruiters recruit for their own organisation and recruiting consultants recruit for a client.
Miljöbedömning av mark- och vattenresurser i kommunal översiktsplanering : en fallstudie av en del av planprocessen i Tierps kommun
This paper describes the integration of environmental assessment in Swedish municipality
comprehensive planning through a chosen case study. The implementation of a new EGdirective in Swedish law, concerning Assessment of the effects of certain plans and
programmes on the environment, should lead to some changes in the way Swedish
municipalities' deals with environmental issues in their comprehensive plans. This could later on lead to new preconditions for municipality comprehensive planning.
The purpose of this study was to investigate how the planning organisation in the municipality adapts to new regulations for impact assessment of comprehensive plans required by the Planning and Building act. Secondly the purpose was to partly participate in the early stages of the planning process and thereby indicate and identify possible environmental impacts regarding the aspects of land and water. This was done as a case study in a well defined part of the process.
Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

Their goal is to accredited according to the ISO 14 001 certificate.
Implementeringen av miljöansvarsdirektivet i den svenska rätten : En europarättslig studie om förvaltningsförfarandet vid miljöskador utifrån principerna om god förvaltning och processuell autonomi
The aim of this thesis is to examine how the EU directive 2004/35/EC on environmental liability impacts the Swedish administrative legal order. The thesis examines the directive through two main EU principles - the principle of good administration and the principle of procedural autonomy. The EU principle of good administration as a concept contains various procedural and substantive obligations that make up the subject for examination of the directive, both as regulated in the directive and as general principles of EU law. The directive is analyzed using a comparative method to determine to what extent the procedural and substantive principles of the directive impacts the Swedish administrative law, and weather or not the Swedish regulations comply with the EU principle of good administration.The results of the study shows that, althought there?s a general principle of national procedural autonomy, the EU principles of good administration do affect the Swedish administrative regulation in various aspects, through the implementaion of the directive on environmental liability as well as general principles of EU law.
