Integrering av pelletsfabrik med Rya kraftvärmeverk i Göteborg : en teknisk och ekonomisk utredning

Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

Energi- och bullerlösningar för fastigheter i tågtrafiken

An environmental review has been carried out at FORIA AB, a transportation- and machine service company, to analyze the company?s environmental aspects from the transportation segment. This report describes the essential background and the methods of identifying and evaluate the environmental aspects. It also describes how the work with the environmental aspects often vary between different actors. The design of the ISO 14001 is intentionally broad in order to apply on all sorts of activities and organizations.

Effekter av ett informationsintensivt material- och produktionsstyrningssystem

We were assigned to do this master thesis by Husqvarna AB who at the time for this thesis just had implemented a new material and production planning system called Replenishment system. Husqvarna AB wanted us to examine the effects of their new planning system to see if it was profitable or not. Husqvarna AB had for a time considered their delivery and supplier service to bee their biggest problem and they wanted to solve this problem by improving the communication with all involved actors in the logistic chain, which they hoped would result in a better mix of products in their warehouses. The aim of this report was therefor to analyze eventual effects for Husqvarna AB when changing from a traditional material- and production planing system to a more information intensive one. The result of this report showed effects on decreasing administrational routines and improved flexibility and lead-times.

Förklaringsmodell för cykelresor i Trondheim : Fysiska och demografiska faktorers betydelse för det geografiska resmönstret

The work examines geographical variations of bicycle use in Trondheim municipality with the aim to create an understanding of what influences the use of bicycles and explain the geographical travel pattern for cycling. The work focuses on the how physical structures generates different transports effects. Where bicycle travels in Trondheim municipality are undertaken is described by using network analysis in ArcGIS, based on aggregated data from the travel habit survey (RVU) in 2009/2010. Trondheim municipality is divided into smaller geographical units (zoner) whose characteristics are described by 19 variables, categorized into 6 groups; Distance, Land use, Topography, Bicycle Facilities, Road characteristics and Demographic factors.By linear regression analysis in SPSS and ArcGIS Spatial Analyst, an explanatory model is elaborated. The variablesdistance to the regional center, workplace density, percentage separate bike paths and hilly terrain explains 78 percent of where cycle journeys are undertaken.

Spårtrafik i norra Stockholmsregionen

Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.

Varför miljöredovisning? : en undersökning av lastbilstransportbolag

Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.

Alternativa drivmedel i den svenska vägtrafiken år 2030 : En utvärdering av den svenska regeringens målbilder

The Swedish government has set up the overall goal that no net emissions of greenhouse gases can occur after 2050. A sub-target has been developed for road transports which states that the use of fossil fuels must be reduced with 80% to 2030 in order to be completely abolished to 2050. A public inquiry mapping how this can be achieved was handed in to the government late in 2013. The use of alternative fuels for road transport, both biofuels and electricity, is expected to give the biggest contribution to the reduction of the use of fossil fuels. The inquiry sets up a number of goals for how much the use of alternative fuels must increase to 2030 in order to reach the overall goal and which instruments that are needed in order to do so.The aim of this thesis is to evaluate how these goals can be reached and what the most likely obstacles that may hinder the reaching of these goals may be.

En analys av TPL-företag och deras samarbete med kunder

AbstractThe purpose of this paper is to analyze TPL companies, and their collaboration with their customers from a TPL perspective. The paper intends to get a bigger understanding of their collaboration, advantages/disadvantages and how the collaboration can be improved. The foundation for the paper is obtained through questions that have been created from the chosen theories about supply chain, third part logistic (TPL) and lean production. We have had open interviews with five different conveyers where we have had our questions prepared and during the interviews asked new questions to get more distinct answers. When we subsequently analyzed the empirical material and by chosen theories we have been able to confirm that the collaboration between the TPL companies and their customers is more of a partnership character.

Regeringens transportinfrastruktursatsningar : En studie av tågtrafikens utrymme i regeringsanslagen för transportsektorn

In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

MON En mittpunkt i periferin

This thesis takes its starting point in the humanistic cultural-geographical concept of place, with the aim of achieving a greater understanding of what constitutes the place Mon today. Mon is located in the northwestern part of Dalsland. Until 1879, the area was described as outlying land, but with the extension of the railway between V?nern and the Norwegian border, Mon's station community emerged. In the mid-20th century, all activities in Mon were phased out, and since then, the place has been inhabited by only about 10 year-round residents.

Energieffektiv Linjesjöfart Till Och Från Gotland

The ferry traffic to Gotland is essential for the island?s ability to live and develop. Yearly, it transports 1,6 million passengers, 500 000 personal vehicles and 750 000 lane meters of freight with four Ro-Pax ferries. The traffic is controlled and subsidized by the Swedish government since 1971 in order to guarantee the inhabitants and industry of Gotland a satisfactory transportation service. As a consequence of the past decades increased traffic quality, mainly due to a decrease in crossing times, the traffic?s environmental impact and costs has also increased.The Master Thesis proposes a new energy efficient traffic arrangement that satisfies the users? preferences in the same extent as today.

Avfallsförebyggande arbete i Norrbottens läns kommuner : En studie om kommunal avfallshantering och avfallsdirektivets påverkan

This study aims to evaluate the waste management in Norrbottens municipalities in key areas such as possibilities to reach the two national waste goals, information to the public, the effect of legislation, future of waste management and differences in geographic- and demographic areas. The Waste Framework Directive (WFD) issued by the EU and incorporated into Swedish law plays a major part in waste management by defining a hierarchy in five steps how waste should be treated. Interviews conducted with each of the fourteen municipalities aimed to find out what step in the hierarchy they are at and what effect the implementation of EU-legislature into Swedish law has had. Based on the interviews a diverse range of answers was found in relation to the questions asked, generally the more populated municipalities saw a more positive future of waste management, mainly because more developed infrastructure to handle waste is already in place. However the smaller the municipality is the harder it is to allocate resources for waste management and problems arise in the form of expensive transports of waste.
