What factors correlates with the use of game meat, wild fish, berries and mushroom in Swedish households : urban vs. rural areas
This study was made to see too what extent Swedes uses consumptive resources such as berries and mushrooms, game meat and meat from fish in their household on a yearly basis. I have also looked into the difference between rural and urban areas in Sweden. Further aim was to determine what factors that correlates with the participation in berry and mushroom picking and the use of game and fish meat within the household. The study was conducted in form of a mail survey that was sent to randomly chosen persons in every municipality in the six northern most counties in Sweden and in the county of Stockholm. In addition a sample was sent to randomly chosen persons on a national level.The results showed there is a difference in use between rural and urban areas in Sweden in all 4 investigated consumptive resources.
Garbage to gardens : design proposals for two decentralised waste management units in Pune, India
The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities.
This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.
Föräldraledighetslagen som diskrimineringslag
The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.
Kvinnor som är entreprenörer Bestämningsfaktorer och regional variation
The proportion of women entrepreneurs in Sweden is, as in many countries, smaller than the proportion of men entrepreneurs. Sweden has therefore created political measures with the ambition to increase women entrepreneurship. However, knowledge about the determinants of women entrepreneurship is needed in order to enable the promotion of it and, at the same time one can question the treatment of women entrepreneurs as a homogenous group. The purpose of this thesis is to investigate the determinants of women entrepreneurship and whether these determinants fluctuate regionally. If this proves to be the case, a more spatial/individual approach should be used, when creating measures to promote entrepreneurship.
Biogas : En systemanalys av Solna Stads matavfallsprocess
Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.
Skattereduktion : Bör arbetskostnaden regleras i lag
The Income Tax Act is enacted what criteria must be met to obtain a tax reduction of household work. Household work is the common term for ROT- and RUT-works. The purpose of the tax reduction is to increase job opportunities and to discourage that undocumented work performs.It is only for the labor cost as tax reduction is given for. The concept of labor cost is defined in law as it is not comprised of cost of materials, equipment or travel. The preliminary work provides no closer explanation what the labor cost includes.
Vad påverkar fjärrvärmepriser i Sverige?: En ekonometrisk analys
The purpose with this thesis is to analyse different factors that can explain district heating prices for energy companies in Sweden. We are further interested in examining if the prices is affected by the use of industrial waste heat in their production and the company?s ownership structure. The method applied is a multiple regression analysis using a panel data set of 50 companies over 5 years (2008-2012). The data used is yearly data obtained from the Swedish district heating association.
Peltierelement - spillvärme till el : Peltier element - waste heat into electricity
The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.
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.
Kan perfluorerade ämnen i kläder bidra till förhöjda halter i reningsverk?
Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.
Kartläggning av källor till organiska föroreningar i avloppsvatten från svenska hushåll
At this point seamen have a lot of tasks of administrative character, beyond the traditional tasks aboard a ship. Due to the new conventions that are formed by IMO, more requirements are added which often lead to time consuming administrative tasks and documentation that should be spent on activities which are contributing to the ships safety. The issue has been observed by IMO that has through BIMCO done a study with the aim to identify and reduce administrative burdens at sea.The primary aim of this study is to find out if safety officers aboard Swedish ferries consider that SOLAS Chapter III, 8.3 och 19.5 regulations are administrative burdens, restricted to muster lists and documentation of training aboard the ship.The secondary questions to the study are if it is possible to remove, combine or change the documents and how much time can be saved by doing this. The question about timesaving could not be answered, because the values were scattered and could not be used for further investigation. The observed values were accumulated by a survey and the result indicated that safety officers did not experience the two regulations as administrative burdens.
Ombyggnation, från sågverkslokal till restaurang. antonio ziakoulis
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
Restvärmeåteranvändning från absorptionsvärmepumpar : en kartläggning av möjligheter och begränsningar vid Vattenfall Värme Uppsala Block 5
Vattenfall district Heating power plant in Uppsala produces district cooling with absorption heat pumps which leads to a large amount of waste heat that has to be cooled with evaporative cooling towers. The Environmental Court has ordered Vattenfall to survey the possibilities to recover the heat, which is the focus of this thesis.The study begins with an overview of the system, and conditions and limitations for waste heat recovery is examined. In the next step alternatives to recycle the heat is evaluated, either by direct recovering or by upgrading.First, the technical possibility of each alternative is discussed, and then the operation time and the amount of recovered heat is calculated. Those alternatives which are possible are brought further to an economic analysis.The cost of investment for each alternative constitutes the basis for a present value analysis. The results are put together in a table where the total amount of recovered heat is compared with the present value for the different alternatives.
Work-Life Balance : En kvantitativ studie av könsskillnader bland civilekonomstudenter
Work-Life Balance (WLB) is defined as the ability to manage both work-life and non-work life successfully. WLB can be evaluated by examining individual?s experience of Work-Family Conflict (WFC) and Family-Work Conflict (FWC), both of which can be assessed by a questionnaire developed by Netemeyer, Boles and McMurrian (1996). The aim of this study was to explore if responses to the questionnaire, the amount of time spent on studies, household chores and sick leave, were gender related or not, among civil-accountants students. The survey included 138 respondents (74 woman and 64 men).
Från frihet till fängelse: En studie av klientflödet på Häktet Kronoberg
In the last decades, lean production has proven to be one of the most important organizational paradigms in manufacturing. The lean concept has also spread into the service industry where it is applied within a range of different areas. The wide applicability of lean principles has spurred the authors of this study to apply the principles in the context of the operations of a Swedish remand prison. The thesis examines the process a client of the remand prison Häktet Kronoberg goes through from the time of arrest until he/she is released or convicted and transferred to jail. Based on lean tools and principles, the thesis maps and analyses this process.
