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.

In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

With the starting point in UN peacekeeping operations, this essay investigates the participation of the Swedish armed forces and how the Swedish soldiers perceive their role in those operations. The aim of the study was to explore different perceptions about the Swedish soldiers in international operations. Partly from the Swedish soldiers perspective and how they perceived their own role as soldiers. Partly from the perspective of civilians, like Swedish aid workers, and how they perceive the Swedish soldiers. The third perspective was from a person with mixed experiences from both the military and the civilian work.

Extreme Production Makeover? fångade vårt intresse för en tid sedan, strax innan vi skulle börja skriva vår C-uppsats. Metoden går ut på att under mycket kort tid förändra och effektivisera en produktionslina för att höja produktiviteten. Vi blev genast nyfikna på om Extreme Production Makeover? skulle gå att omsätta i administrativa flöden och tjänste-flöden med ett informationslogistiskt perspektiv.Inom produktion finns det en lång tradition av att arbeta med effektiviseringar och förbättringar.

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder. Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3.

This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

[Abstract: This study examines the observed difference between Swedish and foreign owners when it comes to nominating committee participation. The background to the study is that foreign owners seem to participate in Swedish nominating committees to a lesser extent than their Swedish counterparts. The focus is on institutional owners and the companies studied are all listed companies who follow the Swedish code of corporate governance. Particular attention is paid to perceived differences in behavior that can be explained using the common corporate governance related theories of Exit, Voice and Loyalty as well as Agency Theory. These explanations are chiefly related to differences in attitudes regarding insider information, different knowledge levels regarding the purpose and workings of nominating committees of the Swedish kind as well as differences due to home market biases.].

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.
