Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Challenges and incentives for sustainable manure management in Russia

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

EU ger eko bland korna - från uppbundet till lösdrift :

ABSTRACT For hundreds of years there has been a tradition with tethered dairy cows in Sweden. The last decades the old fashioned way to hold cows have been questioned and the number of dairy cows in loose housing has been increasing. Last year (2004) 19 percent in total of all farms with milk production in Sweden had their cows in loose housing. Because of EU-legislation concerning all organic production no farms are allowed to build tie stalls any more and after 2010 all organic dairy cows are supposed to live in loose-housing systems. The aim of the thesis was mainly to find out the number of farms with tethered organic dairy cows and if they will continue after the year 2010. Furthermore the purpose was to study if there are any regional differences, how countries similar to Sweden interpret the EU-decision about tethered cows and differences in buildings between organic and conventional farms and the reasons to them.

Ensiling wet brewer's waste in peri-urban areas of Kampala, Uganda

Ett av de vanligaste fodermedlen hos jordbrukare i Kampala är drav, en biprodukt vid ölframställning. Hög efterfrågan, dyr transport samt dålig lagringskapacitet leder till att tillgången på drav begränsas. Ett sätt att lagra drav och således förbättra tillgängligheten är genom ensilering. Denna studie genomfördes som en Minor Field Study, och var en del i ett projekt mellan SLU och Makerere University, ?feed for livestock in urban/peri-urban areas of Kampala?.

Värdeflödesanalys och förbättringsförslag på Pallco AB : Value stream mapping and improvement proposal at Pallco AB

This report is a study made at Pallco AB. Pallco is a subcontractor that is specialized on steel and aluminium components.The aim of the report is to show an improvement proposal that leads to a reduction of the storage and improve the flow through the production of one item that is a part of a product that Pallco manufactures.With the increasing competition from other countries who can manufacture with lower costs must Swedish companies try to make theirs manufacturing as efficient as possible and remove all waste. By using the tools of Lean Production it is possible to reduce the costs and increase the efficiency.The method we used is value stream mapping. A map of the present condition has been made and then different improvement proposal were discussed. A map of a future condition has also been designed..

Nacka golfklubbs avfallshantering

Sedan Nacka golfklubb införde källsortering år 2003 har golfklubben funderat över hur deras sortering och avfallshantering egentligen fungerar. I samband med den miljöcertifiering golfklubben ansökt om att få via Golf Environment Organization (GEO) skall ett flertal områden på golfklubben ses över, varav avfallshanteringen är ett av dessa områden.Syftet med examensarbetet är att undersöka hur Nacka golfklubb idag avfallshanterar och ta fram ett underlag för den certifiering golfklubben ansökt om inom det givna området. Underlaget för certifieringen ska baseras på certifieringens krav och rutiner för förbättring ska baseras på kunskap, hantering samt minimering. De metoder som använts är litteraturstudier, intervjuer, studiebesök samt en analys utifrån Sustainable Development Records (SDR).Resultatet av SDR gav en generell bild av golfklubbens effektivitet, sparsamhet och marginal. Genom SDR kan golfklubben i framtiden fortsätta att mäta och jämföra sina resultat för att se om verksamheten går mot en mer hållbar utveckling och avfallshantering men för att göra detta måste en grundligare undersökning i framtiden genomföras i samband med en avfallsrevision.Utifrån det rutiner golfklubben har rekommenderas ett flertal förändringar för att golfklubben ska få en bättre standard inom sin avfallshantering.

Varför handla svenskt kött? : en konsumentundersökning

The background to the work bases on the consumers view around Swedish and foreign meat products, and how the attitude around the meat products is pursued in the shops. The consumers request high meat quality and security . Many consumers value local produced and ecological meat products but the price is too high. We have done verbal interviews with consumers on three different shops, where we asked questions and had dialogues around Swedish meat products where the consumers have told us their arguments and opinions about Swedish and foreign meat. The result shows that the majority of consumers consider that it is important to know that meat is produce in Sweden.

Dried distiller?s grains with solubles and Swedish grown soya beans as protein feeds for dairy bull calves

The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.

Hjortpark, kronoskog och ladugård : En bebyggelseundersökning av Skyttsie Hage på Skanörs ljung

This essay is about a deserted medieval habitation called Skyttsie Hage which is located in the south of Sweden in the Scania province where it lies on a moor on the Falsterbopeninsula. Remains of five to six larger buildings have been found here with a surrounding earthwork, although it's not known for sure what kind of habitation they have been part of. Local folklore from the 17:th century states the area as a place where pirates lived, and that this was the reason for it's devastation. Another says that there once stood a breedingfarm belonging to the danish crown. Archaeologists have made several speculations which includes a deer park, a royal estate, an isolated farm or a smaller village.

Arbetsprestation, samarbete och sammanhållning i påfrestande arbetsmiljöer: en fallstudie inom beroendevård

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.

Kvävemineralisering från stallgödsel beroende på olika grad av inblandning i mark

The impact of the distribution in the soil volume of two farm manures on the net mineralization and immobilization processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil (MIX). During the two weeks of incubation, few significant differences in net mineralization were seen between TOP, MID and MIX. However, there was a tendency that MIX led to a larger net immobilization of N than placement at one point (TOP and MID). This is also the result in the literature.

Rolf Edberg : En studie av ett miljöfilosofiskt författarskap

In this essay I have tried to present the ideas and thoughts of the Swedish author Rolf Edberg (1912-1997), journalist, ambassador and county governor. By many regarded as an environment philosopher and the introducer of deep ecology into Sweden. The essay emphasizes Edberg as a modern renaissance man of important knowledge with a rhetorical force to present and generalize the problems the planet Earth is meeting. The paper compares him with Henry Thoreau but also finds a close but perhaps unintended relationship with the German philosopher Ernst Haeckel although Edberg himself claimed to be a Darwinist at heart.The essay stresses on four characteristic features in his authorship namely 1) a holistic view of nature and man, rejecting dualism for monism; 2) a cosmic relationship within the whole universe and also between organic and inorganic matter; 3) the planet Earth is in a crisis due to an uneven and unjust distribution of the resources of the Earth, the nuclear weapon threat and the overpopulation; 4) the evolution and not the religion has the answer to our existential questions..

Slam ? en outnyttjad resurs i skogsbruket

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

Miljöarbete i försäkringsbranschen : Agria Djurförsäkringar AB

It has become more and more common that companies in the service sector are beginning to understand their own effect on the environment and thus the need to contribute to a sustainable development through acting in a deliberate way. Serious environmental work can help a company to improve their image and in that way win competitive advantage that leads to improved profitability. In a short time perspective, adjustment to the environment is an opportunity to gain competitive advantage and an opportunity to develop a profile. In a long time perspective it is about survival. The environmental work has become a sequel to the work with quality.
