Gimo bruksområde - inventering och riskklassning enligt MIFO fas 1 :

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

MÄN MED KLASS - En jämförande studie om maskuliniteter och klass

The focus of our dissertation is masculinity which is often a topic of debate in today?s society concerning areas such as violence, sport and paternal leave. Male studies are a relatively new field which means there is a lot remaining to be explored. We have chosen to explore how social class reflects on male identity. The reason we have chosen social class as a variable is due to a focus in the general debate of identity amongst the social sciences towards identities formed through consumption in the world of global mass-media.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Hur miljövänlig är dagens optikerbutik, och hur miljövänlig kan den bli?

SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

Biogas på Wapnö : Analys av framtida energisystem

Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.

"Jamen jag då" : Heterosexualitet och tvåsamhet i Gun-Britt Sundströms Maken

This essay is investigating heterosexuality in Gun-Britt Sundströms Maken. With help from the queer theories of formost Judith Butler, but also to some extent the ideas of Michel Foucault, I have tried to answer the question of which norms are becoming clear and which are being broken in the novel. I have also looked at a few of Gayle Rubin?s opposites in her sexual value hierarchy. Some of the norms that are brought to light in the essay revolves around faithfulness, lust towards the ?right? person and for the ?right? reasons.

Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

Projektledningsmetoders syn på slöseri inom mjukvaruutveckling : Vad är slöseri inom mjukvaruutveckling och hur kan det minimeras?

SammanfattningBegreppet slöseri, av engelskans waste, är en term som i dagsläget saknar en klar och entydig definition inom mjukvaruutveckling. Denna rapport har skrivits vid Kungliga Teniska Högskolan i Stockholm och syftar att klargöra termen slöseri och vad den innebär men hjälp av olika projektledningsverktyg från IT-branchen. Det har framkommit att förtag sällan jobbar med en och endast en projektledningsmetod inom mjukvaruutveckling utan det blandas verktyg från olika metoder. Det är ofta brist på kunskap om valda verktyg och hur de ska användas samt vilka olika verktyg som kompletterar varandra eller ej är kompatibla med varandra. En ökad medvetenhet kring valda modeller och verktyg skulle leda till ökad effektivitet och minskat slöseri.

Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

Gräset är apoteksgrönt eller var går gränsen för ett gränslöst språk : om nationell identitet i svensk språkpoesi

Based on the on the assumption that the two recent Swedish poetry collections mil by Anna Hallberg and mallamerik, mallamer, malameri, mallame, amerik, mallameka, merikka, by Lars Mikael Raattamaa, are constructed with theoretical questions about identity, national identity, language hierarchy and power in mind, this study aims to investigate the ways in which these issues come to expression. Simplified, the term language-poetry, or språkmaterialism, can be used to describe a language-philosophical poetry that aims to eliminate the hierarcic structures between writer and reader in a text and invite the reader to become the co-worker of it. The study shows that by different ways of eliminating the centre of the text, the text is made democratical. But one question that this study asks is how can a nation's conventional and standardised written  language ? the language of the centre ? be used to write itself out of this centre into the margin? Stepping from a theoretical background of postcolonial theories on identity and national identity, including reflections as those given by Benedict Anderson, Madan Sarup, Timothy Brennan, Stefan Helgesson and Mia Cuoto, the analysis points out how this poetry laborates with the terms bugging, repetition, national language identity, and space as poetic material, in order to work in line with ? and contrary to - conceptions of a unified and shared language.

Vindkraftens framtida scenarier

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a Waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

Tillståndsprövning - för lantbruk med djurhållning : en intervju undersökning med länsstyrelserna i Kalmar- och Hallands län.

The task of making a correct application for B- activities is the foundry time consuming task. Information and facts concerning your entire business activity shall be attached into a description of environmental consequences, which will be the basis for the decision making whether the activities shall be granted a permission to practise environmentally hazardous actions or not. When the Environmental Act were established 1999, the permission process became more extensor. With this study I want to give an insight about how these applications are made. The methods I have used to collect information are a study literature where the Environmental Act has been the focus, and qualitative interviews with two County Administrative Board. I used the Environmental Act to understand why permission is needed and the interviews to give me insight in how the work is done. My conclusion is that it is very unusual that an application is granted without complements.

Biogaspotential vid samrötningav mikroalger och blandslam från Västerås kommunala reningsverk

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.
