Idag ställs stora krav på företag att vara miljömedvetna och resurseffektiva i sin verksamhet. Vid mjukpapperstillverkning används stora energimängder och inom industrin har det under många år funnits en strävan att energieffektivisera processer och att tillvarata spillenergi, bland annat genom värmeåtervinning. Valmet Tissue Technology Center i Karlstad har idag en pilotmaskinen utan värmeåtervinningssystem. Den här undersökningen gjordes i syfte att ta reda på hur stor återvinningspotentialen är för värmeväxling i pilotmaskinens torkpartier, bestående av Yankeekåpan och TAD-cylindrarna. Tre maskinkoncept undersöktes: DCT®, NTT? och TAD.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

Syftet med rapporten var att studera möjliga återvinningstekniker för Ragn-Sells. För detta användes litteratursökning och intervjuer. Återvinningstekniker som studerats är mekanisk bearbetning, mekanisk återvinning, kemisk återvinning och viskostillverkning. Flera underklasser till dessa metoder studerades också, liksom flera sätt att tillverka återvunna produkter. Rapporten nämner ett urval av återvinningstekniker och försöker inte nämna alla tillgängliga återvinningstekniker.Återvinningsteknikerna har sorterats enligt prioriteringen i EU:s återvinningsdirektiv (2008/98/EG).

SammanfattningEn ånganna monterades i EGR (Exhaust Gas Recirculation) slingan på en 12,7 liters Scania Euro V motor (DC1306). En modell som beskriver Rankine cykel togs fram med vatten som köldmedium i simuleringsverktyget GT-Power. Ångpannan i GT-power modellen kalibrerades m.h.a experimentell data.Simuleringarna visade att det optimala ångtrycket, det trycket där högst effekt kan erhållas från expandern, är beroende av EGR temperaturen. Det innebär att ju högre EGR inloppstemperatur desto högre optimalt ångtryck. EGR temperaturen i punkt 2 i ESC cykeln är 514? C för denna motor, vilket resulterar i ett optimalt tryck på 120 bar enligt simuleringen.

I detta kandidatarbete skapas en animation för att visualisera användarinstruktioner för en balpress. Förberedelser utförs i 3D-CADprogramvaran Geomagic Design 2014 innan arbetet med animeringen påbörjas i programmet SimLab Composer Animation. I förberedelserna rensas modellerna och modifieras. Modeller som saknas skapas. I detta förslag på visualisering av ett moment i användning av balpressen är i syfte att underlätta för brukaren hur den snabbt kan använda maskinen. Användarens perspektiv sätts i fokus hur den kan tänkas betrakta och uppfatta maskinen genom instruktionerna i animeringen.

The ever-growing e-commerce brings many opportunities for society's consumers and businesses. Digitization has strongly contributed to these opportunities and has, among other things, facilitated the search for information and increased the range for the customer. While the opportunities are many, the increased consumption has also brought consequences. The increase in consumption contributes, among other things, to quantities of deliveries and returns as well as increased waste, all of which results in environmental destruction. The issue of sustainability is very topical today and is influenced by almost everything today. In connection with the markets changing, the consumers' behaviors and expectations also change.

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

Arvika Fastighets AB is a municipal subsidiary tasked with managing all green areas in the municipality, with a strong focus on the City Park and plant beds in the city centre. These areas generate large amounts of green waste, which is currently transported to the municipality's composting area at Lycke. Currently, the material is piled up and turned once a year without using the resulting soil for flowerbeds, lawns, and shrub/tree plantings. The purpose of the study is to determine if Arvika can compost the green waste in a more efficient manner and produce weed-free soil ready to be mixed into various substrates for different purposes. Interviews with the Swedish Church and several municipalities in Sweden have been conducted to learn from their experiences and knowledge of how they make their composting work.

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

AbstractOur purpose for making this study is to study the implementation, the use of and the effects of Lean within our case objects.  We chose to make this thesis by case studies. The three themes mentioned above is also the main research questions that we aim to find an answer to by this study. We have chosen to do a cross section analysis where we conducted structured interviews to find answers to these questions. The theoretical reference frame consists partly of traditional theoreticians within Lean but also more recent research within the subject as well as theory specifically for Lean within the Health Care sector.The result of this study shows in all our case studies that the Management has been supporting the implementation, but that the implementation process proceeds faster if also the professionals are involved in the process.  To succeed with the implementation there is a great need for good reasons and strives that can benefit the professionals. By the use of Lean our case studies have evaluated its processes, with the main intentions being to reduce waste activities and to create flows with ?pull systems?.
