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 biologisk mångfald ökas i ett avsatt skogsområde? : skötselplan för Storskogsberget på Holmen skogs marker, distrikt Umeå

The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.

För Sverige i rymden : Fuglesang, föreställningar om rum och svenskhet

The senior essay examines the geographical imaginations, notions of Self and community that were mobilized in the media and by the government in conjunction with an event, namely, the space voyage of Christer Fuglesang ? the first Swedish astronaut in space on December ___ 2006. The study is a critical investigation of media discourses, representations of space, and geographical imaginations that were triggered by the event. The specific issues addressed by this study are (a) which representations of Sweden were mobilized in narrating the event? (b) In what ways has Fuglesang´s space voyage influenced the image of Sweden? (c) How was the event rallied vis-à-vis discourses of entrepreneurial culture and neoliberal growth by the government? (d) Which themes and clichés were mustered in the media dramaturgy of the event? (e) Which topics were excluded in media narratives and representation of the event? (f) Have familiar geographical imaginations, notions of Self and community been reconfigured? If so, how?The present study analyzes narratives of the event in the two largest newspapers in Sweden - Aftonbladet and Dagens Nyheter, as well the two biggest TV-channels ? Swedish Television and TV4.

Stadsrum och stadsliv - Bebyggelsestrukturers inverkan på kvalitet och innehåll i det offentliga

ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.

Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :

Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse. This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.

Skillnader i vatten- och avloppshantering inom EU : En jämförelse mellan Slovakien och Sverige

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

We are dependent on PPPs - A case study on Public-Private Partnerships

I olika perioder har ämnet våld inom psykiatrin lyfts fram i media, ofta i samband med att ett våldsdåd har begåtts av en ?våldsam psykpatient?. Varken i media eller i den tidigare forskningen är det vanligt att ämnet blir belyst ur ett patientperspektiv. Denna kvalitativa studie försöker fånga ett inifrån-perspektiv och tar sin ansats i att försöka beskriva vad som kan leda fram till att det uppstår konflikt- och våldssituationer på en sluten psykiatrisk avdelning. Studien har genomförts med hjälp av samtal med sju personer med erfarenhet av våld under sin vistelse på en sluten avdelning.

World Trade Center : ett arbete om hur myten påverkar oss

Det här arbetet fokuserar på den profana och religiösa människans omedvetna arketypiska arv som vi fått genom myterna, och vidare på hur detta påverkar oss i särskilda situationer. Som exempel har jag fördjupat mig i terroristattacken mot World Trade Center den 11 september 2001.I min första del beskriver jag myterna och olika mytkriterier, hur de är uppbyggda och vad de innehåller. Gemensamt för de olika myterna visar sig vara kampen mellan kaos och ordning och/eller det onda och goda, där harmoni måste råda på det jordiska planet såväl som på det gudomliga. I denna del tar jag också upp tidens betydelse och hur både den profana och religiösa tiden är av cyklisk natur där nyåret och återupprepning av högtider är av stor vikt för den psykologiska bearbetningen och personliga existensen.I min andra del beskriver jag staden New York och dess betydelse för innevånarna själva och omvärlden, som en stad med grandios arkitektur som själv talar om sig som en stad som symboliserar absolut frihet, välgång och tillväxt. Jag beskriver också tvillingtornen i World Trade Center som en axis mundi, ett mänskligt strävande åt det gudomliga, i världens navel, den absoluta mittpunkten.

Malmö Kommunala Bostadsbolag Fastighets AB owns and administrates Örtagården housing estate in Rosengård which is a characteristic million programme housing area. Örtagården is densely populated which naturally creates an environment that is exposed to wear and tear. The area is today undergoing a change where new proposals and strategies are to be designed for further development of the inner yards. MKB also wishes to develop the park area which is centrally situated in Örtagården. The purpose of this study was to make an analysis of the development of Örtagårdsparken from when it was planned and constructed up until the state it is in today.

Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?

Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.

Påverkan på Valboåsen från verksamheter inom Svedens industriområde samt närliggande områden : hot mot grundvattnets kvalitet och kvantitet?

The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasin

Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.

Om förtryckande strukturer

This paper is a critique of an article in the Swedish magazine Filosofisk Tidskrift (Philosophical Magazine), in which professor Per Bauhn maintains that there is something wrong with having a group perspective in moral and political matters. In this article Bauhn makes three conclusions. The first one is that you violate Hume's law if you draw the conclusion that something is an oppression only from descriptive premises, which for example communitarians does according to Bauhn. He argues that ?oppression? is a normative term, and therefore it requires at least one normative premise.

Strömmar av vatten och politik - en studie om policyprocesser och anpassning.

One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.
