This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.

Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

Denna rapport innefattar ett examensarbete av Manne Hellsing, studerande på Mälardalens Högskola inom Ingenjörsprogrammet, Innovation och produktdesign.Uppdraget har utförts för och på företaget Calesco i Kolbäck och utfördes mellan den 1/4-2013 och den 13/6-2013. Det uppdrag som delades ut av Calesco bestod av att konstruera en ny typ av vattensängsvärmare, med någon form av trådlös styrning. I detta arbete ingick att undersöka vilken väg som var den rätta att gå med framtidens vattensängsvärmare samt att skapa en prototyp av konceptet.För att kunna angripa problemet på rätt sätt utfördes noggranna förstudier i början av projektet. Med hjälp av undersökningar av befintliga produkter i Calescos sortiment och undersökningar av konkurrerande produkter skapades ett bra grundmaterial för att kunna fastställa vad problemet faktiskt var och i vilken riktning projektet borde gå. Nuvarande produkter undersöktes med en bred grund där all information snappades upp, oavsett hur viktig eller oviktig den till synes var.

The running of gas turbines with low emissions causes high pressure pulsations to arise in the combustion chamber. These pulsations are high amplitude sound vibrations. At some frequencies these are harmful to the gas turbine. Hence these pulsations are monitored to avoid operating conditions where pulsations are specifically harmful. It is necessary to expose the system of known pulsations to verify the functionality of the monitoring process.

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.

Denna studie avser att ta reda på om någon förändrad effekt kan fås gällande bränsleförbrukning och emissioner då dieselolja strömmar igenom ett magnetiskt fält innan det förbränns i en dieselmotor som driver en generator. Utrustningen som ger upphov till magnetfältet har tillhandahållits av ett kommersiellt företag. Studien består av två delar, en teoretisk del och en praktisk del. I den teoretiska delen presenteras tidigare vetenskapliga studier inom ämnet samt hur tillverkaren av utrustningen menar att tekniken fungerar. I den praktiska delen har tester gällande rökgasemissioner och bränsleförbrukning gjorts.

The society of today can?t manage without transportation. We need transports to getfood, to go to work and to create new products. The transportation ofgood is thus an important part in the function of the society and they?ll increase, bothin number and in amount.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

In the last few years the environment becomes more watchful, even for us farmers. All agricultural enterprises that exceed 200 animal units must be tested according to regulation of environment. A farm business with 200 animal units and more is classed ?environmentally hazardous activities? and has to make an environmental impact assessment for the business you have today, and the activity after expansion. Before you can construct a building and expand the numbers of animals is a lot of applications to make. I have in this project restricted me to establish a environmental impact assessment and a consultation foundation. To make a environmental impact assessment is the big part of the application. The environmental impact assessment take a lot of time and you need skills for all the rules in the environmental code to be abele to make an environmental impact assessment approved. The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws. The purpose of the environment code is to promote sustainable development which will assure a healthy and sound environment for present and future generations. Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall mean the discharges of wastewater, solid matter or gas from land, buildings or structures onto land or into water areas or ground water.

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.

AbstractThe indoor environment affects the human performance. Noise pollution, poor lightning and coloring are some of the factors that affect our work performance. The human is also affected by the air change and temperature, these factors are in most buildings possible to adjust and through this make economic savings. To find out about the indoor environment in the O-building a questionnaire was handed out, measurements/surveys and an interview was also made. 108 questionnaires where handed out to employees and students.
