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.

In order to highlight and specify how these factors can be applied on a specific company Thule has been our focal point. Thule.

The purpose of this study is to examine in what way a strong corporate culture can have an effect on the ways that individuals perceive their own identity based on different social aspects, thereby meaning the influence of personalities in relation to the environment. In this essay I have used the theory of employer branding in an analysis of the corporate culture at Ikea Barkarby, with the purpose to answer the following questions: How does the relation between the employee and the corporate culture appear from an identity perspective, i.e can an individual?s identity be affected by the influence of a strong corporate culture? If the corporate culture has an influence on the individual?s identity, what rhetorical tools are part of this? How can the surrounding corporate cultures possibly influence the employee?s process of becoming a part of the corporate culture? The method of research that was used in this study is a framing analysis and a semistructured interview method. In the discussion of the influence of social environment on identity I have used the rhetorical term doxa. The material that was examined was an advertisement for employment from the Ikea Barkarby website as well as the response from my interviews of some of the employees.The result of the analysis shows that it is possible for an individual to negotiate with himself about his identity in relation to the actual situation and environment, meaning a possible transformation of the individual?s behavior in different social contexts, in this example the corporate culture at work.

Background: Research results show that the potential of corporate social responsibility (CSR) has increased. That means there is a growing pressure on Swedish companies to act with responsibility: general public has a positive attitude towards companies that communicate their CSR. Advertising agencies have been criticized by their way to manage the question of social responsibility. One of the characteristics of an advertising agency is their anonymity; even though their products are extremely visible, it is rarely clear who gave rise to an advertising production. If this is put in relation to CSR in general, we find ourselves in a contradictory situation when CSR in many cases is about exposure of the responsible corporation.

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

The report contains three parts. The first part is a summary and overall presentation of thermalcracks and preventing measures against such cracks. This is a theoretical part where theinterested designer can get acquainted with various alternatives, be guided to more detailedliterature, and receive some practical information regarding the design of the respectivemeasures.The second part deals with calculation of the risk for thermal cracks and design of water coolingas a limiting measure. Two complementary methods are reviewed for efficient calculation:?the handbook method CraX1(by Lulea University of Technology) is used for quickverification?finite differential analysis in the calculationtool ConTeSt Pro for more precise projectingHere is also presented a development of existing standards through design of the cooling systemby means of the Bernoulli equation.

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

If Swedish companies are to compete with companies in low-cost countries they have to achieve a more efficient production. The purpose of Total Productivity Maintenance (TPM) is to increase the company's profitability by increasing the productivity. TPM is a method that involves all employees and aims to prevent failures in order to increase the availability of existing equipment.The aim of this paper is to evaluate the implementation process of TPM and give recommendations for the further implementation process. The conclusion and the analysis are based on a case study done at a production department at ABB Cewe-Controls facilities in Nyköping. The case study consists mainly of qualitative data from participation observations, surveys and interviews.Commitment of the management is a key factor in the implementation process of TPM.

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

This thesis explores how the city of Gothenburg integrates and use social capital, defined through factors such as trust and cooperative networks, in its crisis preparedness strategies and how this can enhance the city's collective resilience. The study aims to contribute to the understanding of how social capital can be leveraged to strengthen crisis management and resilience in urban environments. The research analyzes existing quantitative data from the SOM-Institute regarding residents perceptions and self-reported preparedness actions and reviews Gothenburg's official civil defense plan for 2024?2027. By examining various aspects of social capital, including levels of trust and cooperative networks across different city districts and age groups, the analysis focuses on how social bonds and community contexts are considered in planning for handling and recovering from potential crises.

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.
