Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

Societal expectations of responsible corporate conduct are currently a fact. It is manifested ina corporate need for limiting and managing external effects, such as environmental impact.An environmental management system is a tool for organizations to structure theirenvironmental work and increase their efficiency. Managing the corporate operations toaccommodate to environmental objectives requires an organizational understanding of theobjectives as well as the procedures. A condition for a successful implementation is the coworkers´ willingness to participate and collaborate.A study made on the co-workers attitude towards the ISO 9000 standard (i.e. qualitymanagement system) reveals that the earlier positive findings are not completely true.

Assessment is considered one of the most important tools used today by people in almost everything they do and learn. This also applies to school, where assessment is considered as a constant companion to teaching and used in order to develop students' learning and skills. Assessment is also an educational necessity which has different purposes and therefore different consequences.                                                                                                                        The idea of ??this thesis was on the basis of the interviewed teacher's perspective to investigate what role the formative assessment has on the development of pupils' learning and knowledge in mathematics for primary education, and explore how the teacher can, according to my informants, work with this assessment practice in the classroom so that it promotes the learning of the students in the best possible way.                                                                To carry out this study, I used qualitative research studies, the interview method, and also talked to five different teachers in the lower school ages on their view at the work of the formative assessment. Theoretical basis of the thesis is also based on the research that says that the assessment can be used to promote student learning and knowledge, but also the teacher's learning?s in the educational process: assessment can and should be an assessment for learning.

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

With increasing energy prices and increased focus on the environment we saw the need for companies to get control over their energy use and their emission of carbon dioxid. An analysis tool that integrates both these areas is, with our knowledge, not available on the market today. Therefore, our project became to develop such a tool.By doing this degree project we would like to clarify that energy consumption and environmental impact are integrated. The less energy consumed by today?s society the smaller the environmental impact will be.

[?If we zigzag in the middle, it?s OK?] The purpose of the following study is to examine the relationship between tourism and religion in a Balinese context. We look specifically at changes in religious practice, culture and mentality, as well as how religious philosophy is used as a tool for limiting the negative impact of tourism. The methods used are semi-structured interviews and participant observations. Central themes in the following essay are globalization in the form of tourism, westernization, subsystem theory and capitalism, which also make up the theoretical framework.

Much due to the fact that the company?s impact on nature only has little to do with how the staff evaluate its ?greenness?.

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Environmental issues are global problems and they are a major challenge for any successful organizational business worldwide. Many challenges and opportunities emerge during the certification process of an EMS. Therefore it is interesting to contribute in understanding these emerging problems during this process.The aim of this study is to explore how the environmental objectives could be achieved at preschools in Uppsala, investigate the perceived challenges and opportunities and to identify the outcome of implementing the ISO 14001, Green Flag at such set up.A qualitative method is used and three Green Flag certified preschools, affiliated to the Uppsala Municipality and located at different geographical location were selected. A structured interview with the environmental representatives from the preschools and the municipality was completed. The so-called PDCA-cycle as a method of evaluating sustainable development and analysing the imperial data is used.The study showed that environmental certification constitutes a great challenge for the municipality of Uppsala.

Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

The purpose of this paper is to investigate some aspects of teaching environmental issues, as they are manifested in another culture. In this paper, I will discuss how you teach environmental issues, how the teaching environment is formed, and what an environmental issue means to a South African teacher, as well as, if there are any cultural aspects to what an environmental issue is. Seven observations were made and qualitative interviews with four teachers teaching Life Science in Cradock, South Africa - The results showed that these South African teachers, independent from each other, followed a similar pattern in their teachings. These patterns contain gathering information concerning environmental issues in the immediate surroundings, as well as using the text book and teaching environmental issues through lectures. It was not possible to draw a conclusion about the cultural aspects in association to environmental issues.

Sweden experienced a decline in exports of 16 percent in the period after the financial crisis. The decline has created a lot of question marks regarding the traditional exports which has started a process with the aim of finding Sweden?s next cash cow in export.Sweden adopted stringent environmental laws early which positioned them as a strong nation in environmental awareness. The stringent environmental legislation meant that the Swedish companies were required to minimize the environmental impact, which created a demand for eco-efficient products. Despite the early demand for eco-efficient products, the international success of the Swedish cleantech companies has been modest.The government can increase firms international competitiveness by encouraging, supporting and promoting activities on the domestic market.

Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the contaminated sites. This builds on the ?Method for Inventories of Contaminated Sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.
