Biogasrötning av socker- och foderbetor : Jämförelse av färska, stuklagrade samt ensilerade betor i laboratorieskala
Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.
Människan, kalven eller gödselbrunnen? Mjölkens destination och fördelning - hos mjölkbonden
A variety of food is produced and passes the whole chain by processing, transport and trade and finally it ends up with the consumer. But in many cases, the food is disposed before it is eaten. Some of the produced food does not even pass the whole entire chain before it turns to waste. The question about food waste in debates is a case of access to food for every human beeing. It is question of consumption of the resources, waste management and an issue of environmental impact.
Karaktärisering av avfallsbränslen
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.
Miljöcertifierade byggnader Värde för investeraren
This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

Generella åtgärder, vilket gäller i samtliga förslag, är betydelsefulla lösningar för att växa mot rollen som ett hållbart bostadsområde.
Materialspill i byggnadsproduktionen : Waste of Material in the Construction Industry
This report deals with issues related to construction waste. Building material that has not been built into the project is defined as construction waste. Cost of construction waste amounts to 4-12 % of the total cost of the project. Moreover, cost of construction waste is 1-3 % of the production cost. The aim of this study is to increase knowledge about the main causes of waste within the construction industry.
Uppfattningar om tryckved bland träbearbetande företag i Sverige :
The primary purpose of this study has been to investigate the Swedish timber industry?s
perception of compression wood. A secondary aim has been to describe particular areas
within the production process where compression wood is likely to cause problems.
This study has mainly been carried out as a questionnaire. In order to connect the findings to current research, additional information has also been collected by means of a literature review. The questionnaire has been intended for sawmills and wood-manufacturing companies from various production classes and owner categories, as well as from different parts of the country.
Stereotyper i toner : Musikens roll i konstruktionen av stereotyper i svensk film under 1990- och 2000-talet
The aim of this paper is to investigate what part film music plays in the creation of stereo-types in the production of Swedish cinema, in the 1990s and early 2000s. This period of Swedish cinema was largely defined through the visualization of life in the smaller provinces of the country. The results were reached through the analyzing of four important works of this era, representing different provinces and genres. The examined movies have shown frequent use of extreme characters and a somewhat hostile environment in search of an interesting story. The music is used in ways of describing class differences amongst the inhabitants and to set the gen-eral mood of the concerned provinces: an agent often working in the unconscious of the viewer in order to affect the final results..

EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO
The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.
Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager
It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006). Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.
Den ekologiskt hållbara staden : en diskursanalytisk studie av styrningspraktiker i Hammarby Sjöstad
This study focuses on the politics around ecological sustainable development in Sweden today, with emphasis on urban development, building and living. The starting-point for this study is the environmental adapted city district of Stockholm, Hammarby Sjöstad. The primary focus of the study is to investigate what means of control the environmental investment in Hammarby Sjöstad is expressing, and to elucidate their ideological, political and social implications. The empirical material is primarily based up on the local Hammarby Sjöstad environmental program along with qualitative in-depth interviews with citizens of this district. The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.
Ett planeringsverktyg för TV-postproduktion
This report describes the process of outlining a design proposal for a resource planning tool for TV post-production. A feasibility study in form of a participant observation has been carried out on-site, which has resulted in a requirement specification. Based on the requirement specification, mockups have been created to illustrate the functions and features that a final planning tool should have. In addition to developing a design proposal, an evaluation of the existing resource planning tool Ganttic has been conducted. Ganttic has been reviewed based on how well it meets the list of requirements.
BIM förändrar produktionen
Because society?s demand for quality, efficiency at low cost is constantly increasing, companies are increasingly choosing to invest new methods to achieve these points. Those who manage to find ways to improve their processes are often the companies that have the greatest chance of becoming a winning player in the market. BIM is a new method that can reduce the internal costs while increasing communications between different parties. However there is disagreement about what BIM is and its purpose.
Prestation och belöning : En studie av meningsfullheten i den svenska industri- och hantverksbranschen.
Abstract: The purpose of this study was to examine the Swedish industry- and craftmanship trade, specifically the relationship between effort and reward and how it affects the meaningfulness during labour hours. Also, what are the possible effects on production efficiency as a whole? Discussed and analyzed through empirics and previous research.38 workers filled out a survey and two interviews were conducted to get a more analytic depth to the data.The results showed that there is little to no reward for high effort during labour hours on the evaluated workplaces, combined with low commitment and meaningfullness. My conclusions are that more ways of effort-based rewards would likely have a positive effect on meaningfulness and thereby the production as a whole. I also show that the theses of Karl Marx are still plausible and relevant in modern day industrial- and craftsmanship trades in capitalist countries..
