Environmental activities are regulated by the Environmental Code, which applies in parallel with other laws. This report is an environmental review for Bräcke Diakoni. The report aims to find out how much environmental impact Bräcke Diakoni has.
Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management
AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.
Matavfall från livsmedelsbutiker : - En analys av den kommunala hanteringen i Sverige samt en detaljstudie av förhållandena i Umeå kommun
Food waste from grocery stores - An analysis of municipal management inSweden and a detailed study of the situation in Umeå municipalityThe objective of this thesis was to analyze the municipal management of food waste fromgrocery stores in Sweden in general and in Umeå municipality in particular. Furthermore theobjective was to account for the different waste treatment methods that can be used and toevaluate them from an environmental perspective. In order to analyze the municipalmanagement a survey was sent to all of the municipalities/municipal waste companies inSweden. A general comparison of treatment methods was carried out on the basis of ascientific review and a system analysis was performed in order to compare three differenttreatment alternatives for the food waste generated in grocery stores in Umeå. The surveyshowed that the legal definition of food waste from grocery stores is unclear and variesbetween municipalities.
Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi
AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.
Adaption och subversion : Återbruk, mening och nonsens i Block av Ulf Karl Olov Nilsson
The Swedish contemporary poet Ulf Karl Olov Nilsson (UKON) creates his poems by recycling and manipulating existing material. Though the overall opinion of his work has been positive, the idea that experimental poetry focus shape on the expense of content has led critics to either interpret the nonsensical and absurd aspects of UKON?s poetics as a consequence of the technical methods he uses to create his poetry, or to look beyond the nonsensical and absurd aspects to focus the fact that the poems creates meaning at all. The poems of UKON?s sixth collection of poems, Block (2005), differ from each other in many ways: some poems are lists and other revolves around a person ? their content and construction vary and they can hardly be read as an expression of one persons thought.
Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation
The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.
Sustainable shopping : consumer behavior in purchasing and donating secondhand clothes
Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.
Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn
The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.
Ledarskap och utveckling i en internationell kontext: en empirisk studie av tre svenska chefers ledarskap i en polsk arbetskontext
Världen idag kännetecknas av att vara en global arbetsplats där landsgränser inte utgör ett hinder för att människor från olika kulturer ska kunna samarbeta med varandra. Vi ser det som intressant att behandla den internationella arbetskontexten utifrån ett ledarskapsperspektiv och se på hur man som chef kan behöva anpassa sitt ledarskap till en ny kultur.Syftet med denna uppsats är att analysera hur tre svenska chefers ledarskap fungerar i och har behövt anpassas till en polsk arbetskontext. Utifrån tre svenska och tre polska chefers utsagor undersöker vi hur förberedelserna inför deras uppdrag gått till, vilka kulturella skillnader som cheferna har stött på samt vilka lärdomar de svenska cheferna tar med sig från sitt uppdrag.Uppsatsen är en empirisk studie som ägt rum inom företaget Stena Recycling AB. Metoden har varit kvalitativ och det empiriska materialet har samlats in genom semistrukturerade intervjuer med tre svenska och tre polska chefer.För att ledarskapet för en svensk chef i en polsk arbetskontext ska fungera behövs förmågan att kunna anpassa sitt perspektiv på organisation och ledarskap samt sin människosyn för att kunna hantera den nya situationen. Inför ett internationellt uppdrag är det viktigt att lära sig om den kultur som kännetecknar ens nya arbetsplats.
Ett hållbart kretslopp? : Förutsättningar för återföring av näringsämnen i humanavlopp till odlad mark; Norrköpings kommun som exempel
Studien undersöker om återföring av näringsämnen, huvudsakligen makronäringsämnena kväve och fosfor, från humanavlopp i Norrköpings kommun kan komma att ske på ett sätt som är i linje med naturvetenskapliga kretsloppsprinciper.Frågan om återföring av näringsämnen och dess problembild är av stor vikt då dagens flöden leder till både resursslöseri och miljöproblem som övergödning. Anledningen till att näringsämnen inte recirkuleras måste bero på någon form av oförmåga hos aktörerna att ta i tu med problematiken.Studien analyserar olika aktörers perspektiv. Aktörerna beskrivs dels i ett nationellt perspektiv men den huvudsakliga fokuseringen ligger på kommunal nivå. Detta på grund av att kommuners roll inom området innebär att de är ytterst ansvariga för utformningen av avloppssystem. Aktörer som agerar i förhållande till kommunen har därför undersökts närmare genom intervjuer med olika representanter för aktörerna.
Development of green space in Dar es Salaam, Tanzania
In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements.
The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today.
The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.
Buskröjning längs skogsbilvägar : en produktivitetsstudie av två kättingslagor
To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.
Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR
The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.
