Kärnkraftens värde i framtiden : en jämförelse med kraftvärmeteknologi från biobränsle
The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable.
The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

The region of interest, north Dalarna, was visited twice to obtain the specificconditions that Pilotprojekt Drevfjällen have. The interviews revealed positive attitude to theincreased dialogue and cooperation that Pilotprojekt Drevfjällen has meant for theparticipants.
Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative
The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.
An assessment of public procurement of timber buildings : a multi-level perspective of change dynamics within the Swedish construction sector
The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.
Mozzarella : En djupdykning i ostmassan
Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.
Charterturismens sociala effekter på lokalbefolkningen : Svenska charterresenärers medvetenhet om de sociala konsekvenser som drabbar lokalbefolkningen på olika turistdestinationer.
In this essay we have been trying to get an understanding of what Swedish charter tourists cares for when they are going on vacation. The Tourism industry is a major field with a lot of winners, but it also comes with consequences. The purpose with this essay is to get an understanding of how aware the Swedish charter tourists is of these consequences. We would also like to get a perception of how the tourists themselves believe that their presence effects the locals at the destinations they are visiting (if they assume that they are). There are several different types of consequences that can appear in the context of tourism, but we have decided to focus on one kind.
Jämförelse av solhybrider
Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.
Conqueror för Indigo
Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.
Optimerade material för optiska komponenter i koncentrerande solfångare
The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.
Ekosocial välfärd : En kunskapsöversikt
There seems to be a consensus in the world that the climate is changing, bringing unpredictable and severe consequences for both humans and nature. The feld of social work is known for helping misfortunate individuals and groups, and is said to deal with people in their environments. Yet there seems to be a lack of giving these environments meaning as also something natural. This thesis has the purpose of exploring the connection between social work and the physical environment made by research literature, using the methodology of literature review. The questions asked is in which ways the physical environment can be connected to human welfare; if so, what implications are there for the feld of social work, and fnally how can the discussion be understood using a typology over environmental sustainability presented by Andrew Dobson.
Ekologisk och småskalig uppfödning av slaktkyckling och kalkon i Sverige :
In Sweden in January 2005, there is only one producer of organic broilers and
none of organic turkeys. But there are, on the other hand, a few small-scale
producers whose housing systems to some extent are similar to what is stipulated
in the organic standards. The aims of this work are to investigate what housing
systems are used by the Swedish small-scale producers of broilers and turkeys,
what main challenges they are confronted with and if there is an interest and a
possibility for a change-over to organic production.
For the first part of this work a literature study was performed with the
purpose of detecting the main health problems in conventional as well as smallscale
production. A special focus was on coccidiosis and leg weakness as those
were considered to be of particular importance.
A study was made of Swedish small-scale poultry production units. In two
groups of broilers from the same producer and in three flocks of turkeys the level
of Eimeria oocysts in faeces and litter was investigated.
Methane emission from nitrate-treated tannin rich feed for cattle in Vietnam
In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.
