Världen krymper i och med ökad globalisering, ska vi kunna leva tillsammans på ett hållbart sätt måste vi alla ta vårt ansvar, stora som små, företag som privatpersoner. Detta medför starka argument för att ta fram lättanvända metoder för hållbarhetsgranskning. Sustainable Sweden Southeast AB (SSSE) är ett nätverksföretag som samlar och marknadsför sina delägares miljöteknikkompetens under ett gemensamt varumärke. SSSE har ett hållbarhetsråd som hjälper till att granska nya potentiella delägare, dock saknas i dag en fungerande metod för detta. På uppdrag av SSSE:s VD har en ny metod för granskning arbetats fram, en checklista med hållbarhetskriterier, vilket också är detta examensarbetes syfte.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.

An old and well known problem in sawmilling is to determine which dimensions /products those are most profitable to produce. Existing optimization models maximize the value of the log. In other words, based upon the market prices of the dimensions the models calculate the best way to split the log. Yet there is a great uncertainty if the most well paid dimensions really are the most profitable to produce. The costs of the process from lumber to sawn products are hard to determine and are therefore often left out from the optimization process. In this study the economic contribution of different dimensions/products are analysed.

Syftet med denna studie har varit att undersöka hur planerare i svenska städer kan arbeta för att minska invånarnas bilresande. I studien har Umeå kommuns arbete med hållbara resor analyserats genom att studera olika plandokument som tagits fram för att vägleda den samtida och framtida planeringen.Tidigare studier visar att det finns ett antal gemensamma nämnare för städer som visar på goda resultat för invånarnas val av hållbara resandet.  Planerarna har haft olika angreppssätt på prioriteringen av trafikstrukturen i dessa städer. Det gemensamma för städerna med goda resultat är att de har planerat långsiktigt, med ett hållbart resande i fokus.Av Umeå kommuns planeringsdokument framgår att visionen för tätorten har många delar gemensamt med dessa städer, varav målen för hur bilberoendet i staden ska byggas bort är det tydligaste. Efter att ha studerat Umeå tätorts nuvarande markanvändning, uppsatta planeringsmål och politiska beslut framgår det dock att översiktliga planeringsdokument och faktiska resultat ligger relativt långt ifrån varandra.

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

Communication of sustainable development has become an increasingly important part of organisation?s corporate branding. Consumers demand more transparency from businesses and want to know more about how they work with these issues. An important part of how internal communication can be used to reach organisational success involves organisation?s employees.

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

Due to the technical development the enterprises of today are forced to creative thinking when it comes to marketing of their products. An example of one of these new methods are the development of product placement which has come to an interesting turn namely advertiser funded programming (AFP). Instead of the product just being a small part of the storyline it has become the story itself. The purpose of this study is to analyse how the advertiser funded tv-production Roomservice, a Swedish home styling program, communicates with it?s viewers as well as how they perceive the message.

The Natura 2000 Network is one of the European Unions many tools concerning nature conservation, and is without comparison the premier contribution when it comes to halting the loss of biodiversity. This essay is a case study on how the regional work with the Natura 2000-network has been carried out in four different counties. These counties are Södermanland, Västernorrland, Jämtland and Örebro. They have been compared based on the theoretical concept of sustainable development. This essay describes how the officials in the County Administrations view the regional implementation of Natura 2000 when it comes to the selection of Natura 2000-sites with forest habitats and the creation of an additional protective measure.

Horse keeping is gaining an increasing interest in Sweden. During 2004 to 2010 the number of horses increased with 10 - 20 %, and was estimated to be 362 700 in 2010. Julmyra Horse Center (JHC), situated in Heby municipality, is a gated community for people sharing a large interest for horses and a vision of a sustainable horse management has been formulated. This study evaluates how the horse keeping of today at JHC, and how an expansion of the horse keeping may affect the risk of enhanced phosphorus load to the nearby lake system Vansjön ? Nordsjön.
