The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.

The usage of temporary work agencies services is increasing in the Swedish labour market and it has also caused some problems. There have been cases where employers have been accused to circumvent the preferential right to reinstatement by using temporary agency workers rather than rehire preference eligible employees during labour need.The purpose of this thesis is to describe, analyse and enhance the understanding of the preferential rights to reinstatement and study when hiring of temporary agency workers, during the period when there is preference eligible former employees, is permitted. The method being used in this thesis has been applied with particular attention to the directives, laws, legislative history and doctrine.The preferential rights to reinstatement in 25-27 §§ of the Employment Protection Act is a protection which states that the employer has to hire employees or former dismissed employees during increased labour needs. The purpose of this right is that an employer should not be able to terminate an employee due to redundancy and then later hire new employees. An employee is entitled to the preferential right as he/she meets the criteria of the Employment Protection Act.

Reptiles and birds are animals that many people don?t have much experience of, so it can be difficult to do a proper animal protection assessment of these animals. It?s hard to determine if these animals is skinny, fat or in good shape, to do that it demands handling of the animal and not many inspectors that works with animal protection have experience of handling reptiles and birds. To see if a reptile or a bird is ill is difficult, when the bird or reptile looking sick it?s often too late to do something. www.blocket.se is a sell and buy page on the internet there many animals switch owner.

There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Chief executives and other persons in management positions are not applicable to the same protection system as other employees. Lagen om anställlningsskydd is not applicable for example. Instead all terms and conditions are in the employment contract, which get increased importance. The employment contract for a chief executive is comprehensive. This essay focuses on employment protection, wages and compensation, loyalty during the employment, secrecy and competitive clauses.

A lot of houses built during the Million Homes Programme are in need of major renovation. Today?s technology and materials are better than in the 60?s and 70?s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality?s construction requirements for new buildings.The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality?s construction requirements.

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

The purpose of the study was to describe the patients? perception of and the dental hygienist students? knowledge regarding bad breath (halitosis) in a University educational clinic in Kristianstad. The study is based on a waitingroom survey (n=100), and a studentpoll (n=40).The result of the patientpoll showed that 58 % felt that they rather would not talk about bad breath, and that 44 % found it that embarrassing to talk about. However 81 % experienced that they were bothered by bad breath from other people. The majority 98 % felt that it was important to smell good from the mouth and 90 % would appreciate if someone could spoke to them that they had bad breath.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

This degree projekt deals with Skanska´s safety at the construction site with focus on personal safety equipment. The purpose of this dissertation is to examine how the rules of personal safety equipment are applied and experienced at Skanska´s construction sites.In October 2004 Skanska started a projekt to make the construction sites more safe. With use of a questionnaire we have made a survey at different construction sites. 80 questionaires have been handed out to Skanska´s employees in the southeast region. While they were handed out we conrolled if the employees at Skanska´s construction sites used head protection, easy visible clothing, safety shoes and identification cards.The result of the survey shows how the rules are applied.
