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.
Handel med utsläppsrätter - hur företagsstrategier påverkas :
Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997.
The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
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.
Framtida turisttrender och landsbygdsturism : en omvärldsanalys av Frölunda-Aspvik Säteris företagsidé
Frölunda-Aspvik Säteri, a company just outside Stockholm within the agriculture and forestry sector, has developed a business idea around countryside tourism as a complement to their existing business. The idea is to offer a high quality and functional way of living in small cottages surrounded by beautiful nature and landscape of cultural importance. There will also be a range of additional activities available such as hunting, canoeing, cycling etc. The project should be done with minimum impact on the surrounding environment and the importance of the ecological system should be at the forefront of all business decisions. At present the company wants to have a better understanding of what the future trends are within tourism, how its business idea fits in with future trends within tourism and how to stay competitive.The purpose of this research paper is to identify the social driving forces that have an impact on people?s lifestyle and choice of holiday destination in the future, and present how these factors affect the travel industry.
Skydd mot nitrat och bekämpningsmedel i dricksvatten : åtgärder och styrmedel i fem länder
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.
Hur ofta bör småhus sotas? : En samhällsekonomisk analys av ändrade sotningsfrister
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.
IT-säkerhetspolicy ? efterlevs den av anställda?
ABSTRACT The main purpose of IT security policies is to protect companies against intrusion and unwanted spread of information. Statistics show that IT related crimes tend to increase and because of that it is important, from the company?s side of view, to be well prepared. The IT security policy is an important part of that preparation. A lot of the crimes related to IT can be deduced indirectly to employees at the companies where the crime takes place.
Ligghallsareans inverkan på beteenden hos högdräktiga ston i lösdrift :
SUMMARY
This pilot study tried to answer the question however the present animal welfare regulations
for horses regarding lying hall area requirements are adequate for horses older than
24 months. The study was carried out at one of the largest stud farms for standard bred
horses in Sweden. Mares in late pregnancy with an initial mean age of 10 years was used
in a behaviour study. The influence of varying space per animal in a loose-housing system
on behaviours like the horses' lying hall use, standing, resting, moving behaviour and
threats was studied. The behaviour at three different horse densities ? 18 mares, 13 mares
and 8 mares (7.4 m2, 10.3 m2 and 16.7 m2 per mare, respectively) ? was recorded by use
of video.
Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader
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.

Fallstudie av Pumas Environmental Profit and Loss Account
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.
Brandväggar för hemmakontor
Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.
Organizing for value creation : a corporate perspective on urban farming
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.
Miljöval för byggnadsmaterial : Med häktet i Helsingborg som referensobjekt
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.
Effektiva styrmedel i jakten på den miljövänliga människan : Miljömål i Hammarby Sjöstad, Stockholm
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..
