Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

Konsumentbeteenden och h?llbarhet. En kvalitativ studie av hur konsumentbeteenden p?verkar h?llbarhetsaspekterna av online f?rs?ljning av kosmetiska produkter, inklusive returer

The ever-growing e-commerce brings many opportunities for society's consumers and businesses. Digitization has strongly contributed to these opportunities and has, among other things, facilitated the search for information and increased the range for the customer. While the opportunities are many, the increased consumption has also brought consequences. The increase in consumption contributes, among other things, to quantities of deliveries and returns as well as increased waste, all of which results in environmental destruction. The issue of sustainability is very topical today and is influenced by almost everything today. In connection with the markets changing, the consumers' behaviors and expectations also change.

Den nya marknaden i Japan : En fallstudie av svenska cleantechföretags möjligheter på den japanska markanden

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Laktester för riskbedömning av förorenad mark :

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

Linderödsgrisen : en inventering av populationsstruktur och produktionsnivå

In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.

Kompostering i kommunal regi: en fallstudie i Arvika Parkf?rvaltning

Arvika Fastighets AB is a municipal subsidiary tasked with managing all green areas in the municipality, with a strong focus on the City Park and plant beds in the city centre. These areas generate large amounts of green waste, which is currently transported to the municipality's composting area at Lycke. Currently, the material is piled up and turned once a year without using the resulting soil for flowerbeds, lawns, and shrub/tree plantings. The purpose of the study is to determine if Arvika can compost the green waste in a more efficient manner and produce weed-free soil ready to be mixed into various substrates for different purposes. Interviews with the Swedish Church and several municipalities in Sweden have been conducted to learn from their experiences and knowledge of how they make their composting work.

Kan implementering av Lean leda till effektiviseringar i skandinavisk sjukvård?

AbstractOur purpose for making this study is to study the implementation, the use of and the effects of Lean within our case objects.  We chose to make this thesis by case studies. The three themes mentioned above is also the main research questions that we aim to find an answer to by this study. We have chosen to do a cross section analysis where we conducted structured interviews to find answers to these questions. The theoretical reference frame consists partly of traditional theoreticians within Lean but also more recent research within the subject as well as theory specifically for Lean within the Health Care sector.The result of this study shows in all our case studies that the Management has been supporting the implementation, but that the implementation process proceeds faster if also the professionals are involved in the process.  To succeed with the implementation there is a great need for good reasons and strives that can benefit the professionals. By the use of Lean our case studies have evaluated its processes, with the main intentions being to reduce waste activities and to create flows with ?pull systems?.

Fröodling av Raj- och rörsvingel i Sverige

Festulolium (Festulolium) and tall fescue (Festuca arundinacea) has not been grown inSweden over a longer period. So far there is no greater area cultivated, but the area isincreasing. Festulolium and tall fescue are expected to eventually replace meadowfescue in many leyseed mixtures to dairy cows in southern and central Sweden. Tallfescue has in recent years become popular again. Festulolium is a hybrid betweenryegrass and fescue.

Betesdrift vid automatisk mjölkning i ekologisk produktion :

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

Samhällsekonomisk analys av ett djupförvar för använt kärnbränsle i Forsmark :

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.
