All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

With the collapse of the Soviet Union and the 9/11 attacks, the landscape of the freedom of religion has changed. The issues now facing freedom of religion varies greatly from the issues that the drafters of the universal declaration of human rights faced after World War II.In the light of the new issues that States face in the intersection of religion and societal interest, scholars have criticized the European Court of Human Rights to give too much leeway to the States in determining how the human rights should be implemented, by using the doctrine of margin of appreciation. Critics of the margin of appreciation claim that it is based on culture relativism and that the doctrine undermines the universality of the human rights. In order to decide if the margin of appreciation has indeed led to a relativization of the human rights I compared it to the jurisprudence of the UN Human Rights Committee and its use of the Syracusa principles. My conclusion is that the jurisprudence of the European Court of Human Rights cannot be considered to be based on culture relativism.

This paper aims to explore the phenomenon urban wind energy, its visual effect on built environment and the factors that affect the opinion towards new elements in the city. A place study of the city Gävle serves as a complement to the theoretical part of the paper. The theoretical discussion opens with an account for the technical and economical conditions of urban wind energy. It presents the technical basics, different types of turbines and a discussion occurring wind related techniques in built environment. Today, the knowledge of how the wind moves and acts in the rural landscape is quite good.

As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

This essay examines the environmental ideological direction of the Swedish parliamentary parties through the private members motions directed to the committee of industry and trade and the committee of environment and agriculture during the governmental time from 2002 to 2006.The environmental ideologies explained is anthropocentrism, ecocentrism and biocentrism. Based on the ideas of these three ideologies main points the private members motions directed to the committee of industry and trade and the committee of environment and agriculture, also matching the search words environment and energy, was compared and analysed.What has emerged is that all parliamentary parties express a desire to create an energy production and producing guide lines which are stringent environmentally and matches the safety requirements. Although the approach to environmental and safety standards differ significantly between them. Basically all Swedish parliamentary parties are more or less anthropocentric in its arguments, which in short terms means that they estimate natures and animals value through their usability for humans or based on their contribution to human feelings of wellbeing.The Centre Party and the Green Party shows hints of weak ecocentrism because in many cases they put animal intrinsic value high, but the human value higher. Moderates are predominantly anthropocentric but they also express some hint of biocentrism in one statement concerning research in order to reduce and rebuild environmentally destroyed areas.

Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.

För att en kvalitativ och driftsäker kraftomvandling från vind till elkraft skall erhållas ställs krav på en mängd olika faktorer. Klimatologiska och tekniska faktorer kräver korrekt dimensionering och anpassning av omvandlingstekniken för att största möjliga energimängd skall kunna omvandlas på ett driftsäkert och energieffektivt vis som vindkraftsägare, nätägare kräver. Vinden är som bekant en oberäknelig kraftkälla. Variationerna i styrka och tid kan innebära en hel del driftoptimeringsproblematik med efterverkningar för vindkraftsverket, nätet och belastningen. Konsekvenserna kan bero på vilken typ av teknik som är installerad i de olika delarna av energisystemet och i områdets elnät.

The equine hoof is often manipulated in purpose to achieve a better stride or to reduce the weight on damaged tissue. The living tissue in the hoof can?t store energy as glycogen and is therefore depending on a continuous supply of glucose for its energy production. The purpose of the study was to determine if wedging (i.e. elevating) the heel could influence the hooves glucose and lactate consumption/production. Five standardbred horses were trained to trot on a treadmill without getting physical or mentally tired.

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

The thesis hears content-error in relation to agreements closed by electronic means. The purpose of the thesis is to elucidate how the rules in 32 §(1) AvtL apply to agreements closed by such means and to evaluate its suitability. The elucidation is done on the basis of, the rules? adequacy in relation to their objectives in collaboration with a comparative view on a selection of international legal framework under private law, such as DCFR, UNCITRAL Model Law, UNIDROIT Principles and CISG.Since Sweden lack a specific regulation for electronically closed agreements, all modern closing methods will be evaluated from the dated outlook of the Swedish Contract Act. In relation to entirely automated processes which results in the closing of an agreement, particular difficulty arise in correlation with prerequisites, which requires a human stance.

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.
