Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

ABSTRACT Skånskt Naturbeteskött is a group of approximately 30 beefproducers in the south of Sweden, who sell their products on the local market. They are certified with Svenskt Sigill, an organisation that works with animal welfare, environmental responsibility, safe food, open landscape and independent qualitycontrol. These producers have to fulfil certain demands regarding pasture and quality of the meat. For this essay I did a market investigation in which I wanted to find out what qualities the Swedish market and the consumers want in their beef. The purpose was to find out what Skånskt Naturbeteskött could do differently to satisfy the market for locally produced beef in the south of Sweden. In the investigation I turned to those responsible for the beef in 12 supermarkets, 4 selling Skånskt Naturbeteskött today, 4 that sold it before but quit, and 4 that never have sold it but might be interested in the future.

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

This study has been done in order to map the supply of vegetarian and vegan food products in Sweden for business clients and consumers. A total of 665 food stuffs were found and classified into six categories. The biggest category was meat substitutes with 302 products and the second largest category was sandwich spreads with 150 different products. Within the remaining categories a varied number of products were found; 86 beverages, 64 cooking accessories, 34 milk free ice creams and 29 plant based yogurts. Of the meat substitutes were 28 only available for business clients.

Russian comfrey, Symphytum x uplandicum, was tested as a plant nutrient source in a trial with tomatoes. Comfrey liquid was produced by Stiftelsen Holma i Höör. Tomato plants of the cultivar Aromata planted in a medium of soil:peat (1:1) enriched with organic nutrients and lime, were fed with comfrey liquid plus Biofer, in three different concentrations. Two different concentrations of BioRika were used as comparison, along with an unfertilized control group. In the comfrey treatment I a total amont of 1g N, 0,23 g P, 0,84 g K, was given to the tomatoes.

This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping. Studies in England have shown that skylark reproduction can be greatly improved within conventional fields, at a low cost, by establishing patches of bare ground (skylark plots). Within conventional farming, herbicides can be used in case a weed problem arises due to implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers. The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.

The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.

All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

The purpose of this study is to examine a brand?s green marketing and its consumers? perception of it in order to compare these views. The idea is to find a potential gap and what effect it may have on the brand. A case study has therefore been made with the grocery market brand Coop with focus on organic food. The material used consists of texts from Coop?s website to represent their brand.

In 2007 Swedish Meats, the dominant Swedish meat-producers cooperative sold its slaughtering and processing industry. The goal of a producer cooperative structure is to create value for members through vertical integration, and to strengthen members? market position. When Swedish Meats sold the slaughtering and processing components, it ceased in some respects to serve the function of a cooperative. This is a lost opportunity for both members and non-members, because Swedish Meats as a functioning cooperative could have exploited its dominant market position to positively effect producer?s prices.

In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead. This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.

Bakgrund: Vi äter allt mer kött. Tidigare forskning har visat på samband mellan högt köttintag och bland annat hjärt- och kärlsjukdomar och cancer. Information om skyddsfaktorer som minskar risken för folksjukdom är begränsad. Forskning om hälsa och sjukdom hos kvinnor är begränsad och därför behövs kvinnors hälsa lyftas fram. Syfte: Litteraturstudiens syfte var att undersöka huruvida ett högt köttintag kan påverka risken för folksjukdomar hos kvinnor.
