Customer Relationship Management perspective is used and Enterprise Resource Planning-systems are the ground for new technology change. The main conclusions are that new technology affects the outcome of companies? relationships towards their customers and suppliers and that the processes and activities between the involved parties are more closely linked. Also involving your suppliers and external actors makes the information handling more effective and companies that do so most likely have a competitive advantage..

Mot en grönare organisation : Niscayah i en säker framtid

 This paper covers how a company must act to become ?greener? and yet still increase profitability with the main emphasis on the inner structure of the company. The research is focused on the Swedish security systems company Niscayah AB, part of the multinational corporation Niscayah Group with approximately 6000 employees. A company can be assumed to consist of seven parts (strategy, systems, structure, super-ordinate goals, staff, skills and style) that have to cooperate for the firm to be able to become more environmentally friendly. Also, the economic performance is of importance and therefore that too is examined.

Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

Fördelning av samkostnader - En studie över hur svenska energibolag fördelar samkostnader mellan el och fjärrvärme i ett kraftvärmeverk

Cost allocation ? a study of how Swedish energy companies allocate costs between electricity and district heating in a combined heat and power plant District heating is today the most utilized alternative for heating in Sweden. In a combined heat and power plant (CHP) electricity and heat are cogenerated. The environmental and economic advantages with this kind of production are high. A problem in a CHP-plant is to allocate costs between electricity and heat since both products are generated in the same process.

Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme

The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.

Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Konstruktion av en fotobioreaktor för odling av alger : ett småskaligt försök

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Livscykelanalys av flerbostadshus ? energieffektiviseringsåtgärder för minskade koldioxidutsläpp

The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.

Funktionell validering av mutation i PUS-1 i en patient med mitokondriell sjukdom

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Naturgas i Australien år 2020 : Framtida konsumtion, export, import och produktion samt konsumtion under inverkan av ett klimatavtal

Australia is one of the largest producers and consumers of fossil fuels in the world. In a society where the effects of fossil fuels on global warming are constantly discussed, the nation?s production and consumption are subject to debate. Problems arise when negative aspects of consumption, such as emissions of greenhouse gases, are put in relation to an increased need of energy and economic growth. However, it is important to distinguish between different types of fossil fuels when it comes to their individual impact on the environment and to analyze the possibilities to increase the more environmental friendly ones.

Livscykelanalys för koldioxidutsläpp från flerbostadshus

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
