En jämförande studie mellan två socioekonomiskt skilda bostadsområden, Araby och Söder i Växjö
… panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis. The increasing emissions of carbon dioxide are connected to …
… requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in …
En studie, ur livscykelperspektiv, av energianvändning och växthusgasutsläpp
… large amounts of energy and contributes to 22-31 % of all greenhouse gas emissions occurring in Europe. More than one third of the produced food is discarded instead of consumed, and food waste make up about 30 % of the waste generated by households. 60 % of this food waste …
- Strategier för systematisk luftkvalitetsmätning
… product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may …
En undersökning av polyesterplaggs fiberutsläpp vid hushållstvättning
… syftar därför till att klargöra vilka egenskaper som påverkar mängden emission av polyesterfiber vid hushållsnära tvättning. Detta uppnås genom experimentella undersökningar av olika materialkombinationer som tvättas under lika omständigheter. Tvättvattnet analyseras och …
In January 2005 the emission allowance system was introduced within the European Union and the first period ends at the end of 2007. The system was introduced in order to decrease the wastes of carbon dioxide and the system is a part of ratifying the Kyoto ?protocol which first …
… construction period the flow equalization will be very limited. Therefore an emission forecast with respect to organic matter was performed comprising the construction period during the years 2005, 2006 and 2007. This to estimate the safety margin to the emission standard during …
effektivt styrmedel mot koldioxidutsläpp? : En studie av kostnadseffektivitet, transaktionskostnader och teknisk utveckling
… public procurement (GPP) can be used as an instrument to reduce carbon dioxide emissions, and consideration of environmental aspects within public procurement is becoming more common in Sweden and internationally. Two product groups that have been pointed out as especially …
… a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed. This reference project was designed both with Swepave and the traditional way. It’s only the construction phase that has been examined, therefore the parts …
En backcastingstudie för ett fossilbränslefritt Stockholms län 2050
… Stockholm county in the year of 2050 may be. The need to reduce the carbon emission to the atmosphere is extensive and of immediate urgency. One part of reducing carbon emission is to relinquish the fossil energy use which is attained either by reducing the energy consumption or …
… 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 …
effekt på mjölkavkastning och betesbeteende hos mjölkkor
… spent grazing and ruminating. Since ruminating animals give rise to methane emissions, methane emissions from the different feed ratios were estimated using equations obtained from the literature. In the trial 27 lactating dairy cows (Swedish Red Breed) were blocked by parity …
effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable …
… förbättring av den lokalamiljön, men den medför också miljöpåverkan i form av emissioner till luft med ursprung frånt.ex. de arbetsmaskiner som kommer att användas för genomförandet av saneringen. Syftet meddetta examensarbete har varit att uppskatta den miljöpåverkan, i form av …
… methods that is the base in our thesis. The amount of energy use or the emissions are not analyzed for neither the Swedish road administrations nor Svevias construction models. Our thesis has compared these two models of constructing a road to evaluate what affects the climate …
