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.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

In modern society globalisation is a fact within all industries, the textile industry included. Due to improvement in areas such as logistics and communication international trade have developed fast. As changes occur rapidly on the global market and companies must adjust and revise their processes in order to stay competitive.Because of the global price reduction consumers around the world expect low-price products, which mean that the companies have to find new ways to produce in a cost-efficient way. To maximize profit most of the textile production is situated in low-cost countries due to its labour-intensive character. It is crucial for fashion companies to allocate their activities in their value-chain effectively in order to reduce lead-times.

Under de senaste decennierna har fokus riktats mot att effektivisera de utgående transporterna, vilket gjort att de inkommande transporterna kommit i skymundan. Företagen har dock på senare tid kommit till insikt om den potential som finns i att även förbättra de inkommande transporterna. Syftet med rapporten var från början att studera hur de inkommande transporterna fungerar samt ur ett kostnadsperspektiv utvärdera potentialen för förbättring. Under studiens gång skedde dock en syftesförskjutning på grund av problem vid fallstudieföretaget. Arbetet kom att fokuseras mer på kartläggning av inkommande transporterna, än på metoder för att förbättra konkurrenskraften, då detta område visade sig vara ett större problem än väntat.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Public concern and the need of responsible way of doing business have brought forward the issue of sustainability at the forefront of discussion in the last decade. Even though, food retailers are playing an important role in the economy, they are exposed for criticism by media and consumers for any socially and environmentally irresponsible business practices because, the potential environmental and social impacts from their operations are significant. These impacts need to be recognized and properly addressed. The main objective of this study was to assess the sustainable business management of a cooperative food retail business in Sweden, known as Konsum Värmland (KV). The necessary data and information on history and status of KV, and its practical activities concerning the implementation of sustainable development programs as well as the motivation and challenges encountered by KV during the implementation were gathered via reviewing different documents, research papers and press releases; interviewing decision makers and other personnel in KV and other researchers from Swedish University of Agricultural University who have investigated KV.

This bachelor?s thesis is a study that examines cactus groups in Sweden from a heritage conservation perspective. Through interviews and an analysis of both historical and modern literature, the research explores why cactus groups became popular and what is required to preserve those still in existence today. A recurring challenge has been the lack of comprehensive source material, leaving some questions open for further research. The study focuses on four cities?Norrk?ping, Skellefte?, Varberg, and V?xj??that have maintained their cactus groups for nearly a century.

Alien plants that have intentionally been introduced to an area for cultivation in public or private gardens constitute the primary pathway of introduction for invasive alien species that spread into nature. Garden owners want species that have satisfying characteristics, these characteristics are often also linked to plant invasiveness. Thus, the horticulture industry plays an important role by making scientifically based decisions and phasing out invasive plants and replacing them with alternative species with satisfying characteristics, but low risks of becoming invasive. This thesis aimed to examine the sale of and the attitudes towards alien plants in the horticulture industry in Sweden. Alien terrestrial plants identified to have a severe risk, high risk or potentially high risk of spreading and becoming invasive according to ArtDatabankens assessment, were examined to see if they were for sale.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

Background and problem: In Croatia, the hotel industry has undergone difficult and unstable conditions since the 90s. Since 2001, however the results in the sector has improved due to increased investment in the renovation of facilities and construction of new hotels.Purpose: The study aims to examine hotel operations on the Makarska Riviera on the basis of tourist business perspective, and examine its quality, service and accessibility.Method: In this study we used a qualitative approach. The survey was conducted through structured interviews and a non-participant observation.Result and conclusions: Satisfied and fulfilled employees, in turn that the hotels will have satisfied customers and may have profitable operations.

When measuring customer satisfaction, many hotel owners felt that the service is good and that they have received a good response from their guests.

In order to suggest improvements for the logistics of STARKA, we felt that we had to analyze all the activities which were related to STARKA's logistic processes. Our primary analysis consisted of a rough but comprehensive description of different functions in the company, and the relationship between them. This was performed by following a typical order through the company to see which functions were affected by the order.Since we needed a more thorough view of the company, we decided to analyze the different products STARKA currently has on the market, focusing on economic data such as turn-over, profit, profit margin, deficiency cost and cost of warehousing. We also analyzed the company's choice of manufacturing processes, organization, warehousing processes, strengths and weaknesses.These analyses gave us a clear understanding of the company and its processes. STARKA is a small, function oriented company with a wide range of products.

Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.

Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.

The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.
