Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

ABSTRACT For hundreds of years there has been a tradition with tethered dairy cows in Sweden. The last decades the old fashioned way to hold cows have been questioned and the number of dairy cows in loose housing has been increasing. Last year (2004) 19 percent in total of all farms with milk production in Sweden had their cows in loose housing. Because of EU-legislation concerning all organic production no farms are allowed to build tie stalls any more and after 2010 all organic dairy cows are supposed to live in loose-housing systems. The aim of the thesis was mainly to find out the number of farms with tethered organic dairy cows and if they will continue after the year 2010. Furthermore the purpose was to study if there are any regional differences, how countries similar to Sweden interpret the EU-decision about tethered cows and differences in buildings between organic and conventional farms and the reasons to them.

The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed. Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

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.

Bakgrund: Den finansiella marknaden och dess tjänster har blivit alltmer komplexa under åren. Utbudet av olika produkter som exempelvis olika typer av fonder och aktier har blivit allt större. Det finns idag många olika handelsplattformar för aktier och fonder. Samtidigt som utbudet av komplexa produkter ökar, läggs mer ansvar på individen i exempelvis hantering av premiepension. Det förutsätter att konsumenten är väl informerad och tar rätt beslut.

Eco certification of small housesTo construct an environmental friendly building and show that as a company you care for the environment, is presently very attractive in the Swedish real estate market.This degree thesis covers the environmental certification called ?Svanenmärkning? the Swan, witch is the Swedish equivalent to the European standard ?the EU Flower?. It is concentrated on the certification process in small houses that the Swedish institute of standard, SIS, has presented. We have worked together with the company Faluhus witch is a Swedish producer of small family houses.Faluhus is located in the town of Borlänge, Dalarna and has produced family houses since the 1950:s. They have a great heritage born in the old Swedish mining culture, with great wooden mansions and country homes.

The purpose of this study was to examine the ways in which the Swedish lifestyle magazine VeckoRevyn construct the sex and love relations of bi- and homosexuals. We analyzed 22 unique texts in magazines, from 2009 to 2014, in order to get a result as current as possible.To represent the magazine overall we have selected texts from various parts of the magazine. With a critical discourse analysis and through relevant and significant theories and perspectives such as social constructionism and heteronormativity, we found that VeckoRevyn represent sex and love relations of bi- and homosexuals through four discourses.The outcome of our study shows that VeckoRevyn only represent a limited part of bi- and homosexuals sex and love relations. In the analysed texts bi- and homosexuals are forced to ?come out of the closet? repeatedly and their sexual relations are rarely represented.

Multi Protocol Label Switching (MPLS) är en routingteknik som blir allt vanligare i dagens nätverk. Vid implementation av MPLS i nätverk är det grundläggande att hårdvaran har tillräckligt hög prestanda för att hantera tekniken. Om så inte är fallet kan det leda till negativa konsekvenser såsom paketförluster eller i värsta fall att routern havererar. Syftet med arbetet var att ta reda på hur processorbelastningen på en router skiljer sig när MPLS var implementerat jämfört med traditionell IP-routing. Routingprotokollen BGP, OSPF och RIP användes tillsammans med de olika routingteknikerna för att se vilket av dessa som krävde minst processorkraft.För att ta reda på hur processorbelastningen påverkades skapades en experimentmiljö.

A great number of empirical researches show that hedging is associated with higher firm value, particularly hedging interest rate and exchange rate. However, there is no clear support for value-added risk management hypothesis in the case of producers of commodities. Moreover, according to Shrand and Unal (1997), there are two types of risks, core business risks (or core risk) and homogeneous risks (or non core risks), which are based on a firm's comparative advantages with respects to the source of risk. Firm can earn economic profits for bearing core risks in which it has a comparative information advantage. Firm earn a zero economic rents for bearing non-core risks, where it has no advantage information than its competitors.

AbstractIn this thesis we analyze how institutions describe the dichotomy between ?problem? and ?resource? when dealing with young adults. We also analyze the consequences of this dichotomy as it involves the younger generation's participation and group identity in today's society. Dichotomies and New Institutionalism Theory is the base for this case study completed in Malmö, Sweden. We have done eight qualitative interviews with politicians and employees in Malmö municipality and a quantitative content analysis of reference documents from both the Malmö and Swedish governments.

Payday loans are becoming a challenge of increasing gravity for society. Statistics show that the number of young adults with financial issues related to such loans has been growing over the past few years. Despite efforts to halt this trend, little is changing. Government mandated warning labels in commercials are typically used to inform about the risks associated with the consumption of certain goods and services, such as alcohol and tobacco. Despite issues related to payday loans, there is currently no legislation in Sweden mandating the inclusion of warnings in marketing of such loans.

The purpose of this thesis is to look into the knowledge city concept and the preferences and requirements of companies on such a city. Furthermore, suggestions of ideal conditions in a knowledge city are proposed. The thesis has been conducted through a qualitative approach where a deductive procedure has been implemented. In order to examine knowledge cities, Barcelona has sketchily been looked at as an early example of a knowledge city, whereas a more exhaustive observation of Copenhagen was conducted. Since the concept of knowledge cities is a rather new phenomenon, models from several disciplines constitute the theoretical framework.

Recently, retailers within the Swedish grocery retail sector have launched lines of products under its own brand, quite often produced by manufactures within the same category of products. The common term of this phenomenon is called private labels. Therefore, private labels could be seen as competitors against branded goods, despite the fact that it is, in several cases, the same manufacturer who produces each of the products.The main purpose of this study is to provide understanding of how the manufacturers choose to position themselves, formulate their strategies and compete on the market among private labels, also to examine the motive behind the manufacturer's choice to produce private labels. The study intends to provide a broader view of how the interaction between manufacturers, retailers, private labels and branded goods appears on the Swedish market. We decided to use a qualitative research method and personal interviews to approach the study.
