Bioenergy from the forest ? a source of conflict between forestry and nature conservation? : an analysis of key actor?s positions in Sweden
Bioenergy from the forest has been heavily debated in Sweden for several decades due to the interest of society to decrease dependence upon fossil fuels and limit the effects of climate change. The actual use of bioenergy from the forest has shifted over the years but increased during the last decades. Private actors within forest and nature conservation sectors play an important role for the development of bioenergy from the forest as well as for the debate and the implementation of political goals. Forestry in Sweden is characterised by ?freedom under responsibility? for private actors and the perspective of governance is valuable for studying actors and discourses.
Doing well by doing good : Hur kommunikation och anpassning av CSR skapar värde
Background: Today, It?s not uncommon that international companies and organizations have a higher turnover than the GDP of developing countries. Consequently, this may suggest that the choices companies make in the context of their business has a great potential to influence the world from an economic, but also from a social and environmental standpoint. From this the notion emerged that companies have a responsibility, referred to as Corporate Social Responsibility (CSR). A clear definition of the CSR concept is difficult to find, more than 37 different definitions has been identified.
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
Hållbar utveckling i värdekedjan
Detta är ett examensarbete inom textil produktutveckling som har sin grund hos uppdragsgivaren Bellaobastian. Syftet med rapporten är att ge en inblick i miljöarbetet i värdekedjan hos mindre konfektionsföretag, vilka svårigheter som kan förekomma och hur den hållbara utvecklingen kan effektiviseras. Vi vill ge mindre svenska konfektionsföretag råd och förslag om hur de kan uppnå en tillfredställande nivå på deras miljöarbete utan tillgång till enorma resurser.Vi har utfört intervjuer, litteraturstudier samt jämförelseanalyser mellan företagen H&M, ACNE och Lindex. Vid diskussion och analysarbetet var det tydligt att miljöarbete i värdekedjan är en komplex process och att det är flera aspekter som spelar in.Vi har kunnat identifiera åtgärder som företagen kan utföra i hopp om att uppnå en mer hållbar utveckling, både specifika som tex, materialval men även mer övergripande som att ändra sitt synsätt. Åtgärderna vi kunde påvisa kretsar kring:- Minska överkonsumtion och effektivisera resurssparandet- Minska koldioxidutsläppen- Använd miljöledningssystem och märkningar- Ändra företagets synsättEn av slutsatserna vi kunnat konstatera genom våra undersökningar är att det inte räcker med att åtgärda problemen.
En studie av miljöfaktorers betydelse för förekomsten av Francisella
This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .
Sustainable shopping : consumer behavior in purchasing and donating secondhand clothes
Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.
Manliga veganer : En narrativanalys om manliga veganer och maskulinitet
The purpose of this essay is to investigate the subject field of male vegans and masculinities through empirical method interviews and narrative analysis. The starting-point for this essay is animal ethics, feminist ethic vegetarianism and theories that suggest that eating meat is one part of the social construction of masculinities. The problem formulation is such as follows:How do male vegans construct masculinity? In an attempt to answer such a question there are three problem formulations:What do male vegans think about the connection between manhood and eating meat?How do male vegans relate to the norms in society?What do male vegans think of stereotype conceptions about vegans?I will come to the conclusion that male vegans think that eating meat, as well as drinking beer, is one part of the social construction of masculinities. Male vegans are aware of norms in the surroundings and the strong attachment of meat normativity in the western culture.
Some people get it. Others are assholes. Kontradiskurs, subversiv potential, hegemonisk makt och performativ marginalitet utifrån tre nivåer av skräpkultur.
Sustainability work is something that is emphasized more and more. Corporate Social Responsibility, CSR, is discussed and the question of how much responsibility companies should really take is frequently in the news. Companies tend to ask themselves how much responsibility they should take. CSR is a common concept of companies environmental and social work and a concept we tend to see here and there in our modern society. CSR includes companies? social responsibilities, both in terms of carbon footprint, working conditions, social responsibility and more.
Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Utomhuspedagogik i skolan
Nature is in many ways considered a source to both physical and mental health among people. Trends in today?s society reveal that children become more distanced to nature. Seen from the perspective of sustainable development this trend is considered crucial: it is of importance that children in their early ages experience nature positively in order to develop a dedication towards environmental issues as adults.The purpose of this study is to investigate how teachers use outdoor learning as an educational tool. Research data were collected through a series of interviews.
Miljö- och hälsorisker med konstgräsplaner
In Sweden today many municipalities and sport clubs chooses to build artificial turfs becauseof the increased period of using the turfs during the year and less maintenance requirementsthan for natural grass fields. What could be problematic with artificial turfs is the rubbergranules used as infill material in the turf matt. The rubber granules are often made fromrecycled tires, which may contain for the human health and the environment, harmful substances.This was the reason why the Swedish Chemicals Agency commissioned a statusreport in 2006 which, among other things, concluded that the environmental and health risksassociated with granules made from recycled tiers in artificial turf fields were small, but thatthere could be a local environmental hazard. The purpose and objective of the risk assessmentwas to identify how artificial turf plans granules can affect recipients in the area closeto the pitches and provide input to reduce the spread of metals and substances harmful forboth human health and the surrounding environment. The work was divided into three parts:(1) the construction of artificial turf pitches and their material content, the spread of granulatesoutside the fields and disposal of artificial turf pitches.
Teknikimplementering vid muddringsprojekt : Viktiga faktorer vid teknikval samt olika aktörers betydelse i processen
There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.

Invasions- och insatsförsvaret : En professionsteoretisk jämförelse
This essay is on the subject of the changes that the Swedish military is undergoing. This essay will take the old ways of alignment thinking, were the military was to protect the nation against an invasion and compare it to the newer way of alignment thinking, where the military is to go abroad and do peacekeeping operations as there main objective. This comparison will be done by using Bengt Abrahamson theory about professions. He uses three parts one is specialised theoretical knowledge, another is ethics and the last is corps spirit. This theory will then be connected to four interviews.
Analys av artificiella marktyper vid vatten med hjälp av GIS, Värmlands län 2007
On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).
