The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

In many European countries there is an increasing concern about the occasionally high concentrations of nitrate and pesticides in drinking water. The advent of the EU Water Framework Directive particularly highlights this. The directive states that all large drinking water sources should be identified and protected from pollution before 2009 and that by 2015 all water bodies should reach a 'good status'. In Sweden about 60 percent of the drinking water sources have protection areas. This means that about 700 new water protection areas need to be designated before 2009. This will affect many farmers, restricting their farming practices. The purpose of this study was to investigate which methods are used in other countries concerning nitrate and pesticide pollution from agriculture. From this, the expectation was to generate ideas on what could be undertaken in Sweden when designating new protection areas.

Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions.  Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

This study focuses on small scale hydropower in Sweden. This means plants with a capacity of up to 10 MW. The study has a special focus on plants with a capacity up to 2 MW. The study has three aims. It strives to describe the small-scale hydroelectric industry in Sweden.

The aim with this essay is to look into what literature has been published in 2006 and 2007 for boys between the ages of twelve and sixteen in order to analyse six of the titles. Our two main questions are as follows:?How is the teenage boy depicted in six of these books? - To what extent is the teenage boy depicted in a gender stereotypical way?.We chose the titles for analysis based on our mapping of the published literature and took into account the authors? gender and age as well as the main themes of the books. As theoretical base for our analysis we used Marias Nikolajeva?s table of gender stereotypes in literature.

Introduktion:Att hållbarhetsredovisa efter GRI:s riktlinjer är idag en standard bland multinationella företag världen över. Vi anser dock att det är mer givande för intressenter att placera företaget i ett större sammanhang och för att se hur mycket företagets miljöpåverkan kostar samhället årligen. Sportsko- och klädesföretaget Puma har i en resultaträkning monetärt uppskattat hur mycket miljöpåverkan från deras leverantörer och egna aktiviteter kostar samhället varje år. Den kallas för Environmental Profit & Loss Account och fungerar som ett transparens-, strategi- och riskhanteringsverktyg.Syfte:Den här uppsatsen syftar till att beskriva hur EP&L kan användas i framtiden.Problemformulering:1. Hur används EP&L som strategi- risk- och transparensverktyg?2.

This report is the documentation of a project in the education Master of Science in Mechanical Engineering. The project was carried out at Alfakonsult AB. The purpose of the project was to map out the transference of information between the different operators in the supply chain of medicine in Sweden and to analyse this in order to reduce lead-time and the total throughputtime. The supply chain of medicine in Sweden consists of producers, distributors, one wholesaler, prescribers and patients. The mapping of the transference of information showed that most operators in the supply chain have done well introducing technical aids to facilitate the transference of information.

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

Today's climate and environmental issues have now been up for discussion for quite long. Various environmental measures have been taken, but it is not always certain that those measures actually are for the better because of the complexity of our environment. Therefore, studies of whole life cycles are very important even if they are time and resource intensive.Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are therefore of great importance.

Målet med denna studie är att framställa en modell för sannolikheten för skred i Cuenca del Arga i Navarra, Spanien, med hjälp av GIS och oskarp logik. Utifrån denna modell framställs en karta som visar områden där det finns sannolikhet för skred. Övergripande har metoden skett i fyra steg. Först har en skredindexkarta framställts, sedan har medlemsfunktioner skapats utifrån dessa med hjälp av skredriskparametrar. De ingående parametrarna har varit sluttningsvinkel, topografisk fuktighetsindex, avstånd till vattendrag, jordmån och markanvändning.

Uppsatsen behandlar styrningsverktyg i arbetet mot ett ekologiskt hållbart samhälle, av kommuner nyttjade styrmedel och de boendes uppfattning av dessa. Fokus ligger på de boendes respons på miljömål i uppbyggnaden av den ekologiska stadsdelen Hammarby Sjöstad i Stockholm.Med hjälp av kvalitativ metod och djupintervjuer med 14 boende studeras de styrmedel som används för att påverka och förändra de boendes miljöbeteende, de boendes inställning till dessa samt vilka drivkrafter som finns bland de boende för att agera miljövänligt.De aktuella styrmedlen; regleringar, ekonomiska styrmedel och informativa styrmedel presenteras med hjälp av citat från intervjuerna och redovisas utifrån strukturell, positionell samt individuell nivå. Dessutom redovisas meso-kontextens påverkan samt individens egna drivkrafter för miljöbeteende.Teorier som tas upp och relateras till det empirirska materialet är makt, governmentality samt relevant urban- och miljöforskning. I resultatet framkommer exempelvis att de boende efterfrågar inbyggda lösningar för ett miljövänligare samhälle. I diskussionen resoneras bland annat kring den krock som kan finnas mellan de olika diskurserna; miljövänlighet och senmodernitet..
