Den textila industrin, en egen värld, är nu under rampljuset som en av de största miljöpåverkande industrierna. Precis som i fallet med många andra industrier så måste textilbranschen intensivt arbeta med att minska sin negativa påverkan på miljön. Slutmålet måste vara att helt balansera uttagen och insättningarna så att man skapar en bransch som blir klimat- och miljöneutral. I denna rapport har en livscykelanalys gjorts på en underställströja från Helly Hansen tillverkad av 99 % polypropylene. Inom denna livscykelanalys har vi noggrant studerat och undersökt fakta för att hitta de processer som har den största påverkan på miljön.

The purpose of this study is to create a method that can be used to produce decisionsupport data for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make longterm projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal. Public reporting of energy use and climate impact has been studied in order to examine the nature of indicators and accounting figures that are commonly used in the field and how long-term forecasts are formulated. In connection to this, the type and sources for the kind of data needed was also examined.

When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method. The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.

Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.

The use of fossil fuels such as coal and gas are a contributor to the global warming. The climate change is a worldwide problem with far reaching consequences that is believed to be very expensive. The United Nations has been introducing a framework convention on climate change. One component of the convention is the Kyoto protocol. The protocol is obligating the developed countries to decrease their emissions of greenhouse gases by 5.2 percent during the time period 2008-2012.

Studien handlar om förklaringar av förändring hos några av de forskare med historiematerialistiska inslag som hade en framträdande roll på 1970- och 1980-talen. Övergången från feodalism till kapitalism och industriarbetarens roll i arbetsprocessen var två fält som var på tapeten under denna period, som kan härledas ur den radikala 68-rörelsen. Med sociologen Piotr Sztompkas systemmodell som teoretisk ram undersöktes Christer Winbergs, Maths Isacsons, Anders Floréns, Lars Olssons och Lars Ekdahls avhandlingar samt ett verk av Alf Johansson. Syftet var att utforska de teoretiska utgångspunkterna och slutsatserna i alstren. Svar söktes på vilka drivkrafter författarna anger till förändringarna i sitt material; var i systemet på mikro-, meso- eller makronivå dessa förändringar inträffar; och vad förändringarna leder till.

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Sweden currently has no legislated regulation of lobbying, but the professional lobbyist can voluntarily subscribe to, among others, the professional code of standars created by the trade association of Public Relations, Precis. There is an ongoing discussion in Sweden to regulate lobbying, both in mass media and in politics. This study examines this debate and focus on which arguments there are for and against lobbying regulation in Sweden. It also attempts to identify the differences, if there are any, between left and rights parties with regards to their views on regulation of lobbying.Tha main method used was document analysis of parliamentary bills which have been raised concerning a lobbying regulation in Sweden. In the theory section, I include four different types of requirements placed on democratic lobbying (se for example Jaatinen 1998, Kitchen 1999, Larsson 2005, Möller 2009 and Naurin 2001).

De internationella klimatförhandlingarna handlar om att hitta lösningar för att stabilisera halten av växthusgaser i atmosfären och att uppnå tvågradersmålet. För att uppnå målet finns olika utsläppsmål att sträva mot. Ett är ett utsläppstak där varje land inte får släppa ut mer än 2 ton CO2-ekv/capita per år för att tvågradersmålet ska uppnås. Ett annat utsläppsmål är att minska de nationella utsläppen med en viss procentsats. EU:s del i minskningen ligger på 80-95 % till 2050.Som en del av arbetet mot målet presenterade EU i mars 2011 en färdplan för ett utsläppsnålt samhälle.

Användandet av etiska standarder som inbegriper sociala, miljömässiga och ekonomiska värden har blivit allt mer vanligt under de senaste åren. Detta på grund av en större efterfrågan från konsumenter. En av de branscher där intressenter efterfrågan ett större samhällsansvar (CSR) är inom livsmedelsbranschen. Ett företag som idag erbjuder certifieringar i Sverige inom livsmedelsbranschen är Kiwa Sverige. Företaget har känt av en ökad efterfrågan av CSR-standarder från sina kunder.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.
