The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

During the past decade environmental challenges have been intensified and given increased attention. This implies that businesses in all sectors strategically need to manage these challenges. The service sector is often considered as a sector with a low environmental impact if the direct environmental aspects are assessed. Still, it has been argued that the environmental impact that the sector gives rise to can create severe indirect environmental impacts. The products and services that are produced by this sector have a relatively limited use of physical resources which may make the environmental impact challenging to visualize. Banks belong to the service sector and it is partly banks that make the development of societies possible.

I arbetet undersöks hur kunskap om systemtänkande och ekosystemtjänster kan användas vid utformning av ett produktionslandskap ansluten till fjärrvärme i området Elleholm i Karlshamns kommun. Anledningen till arbetets fokus är slutsatser om utbyggnad av resurshushållande växthussystem i Elleholm som drogs under masterkursen Energy Landscapes, våren 2014. Målet med examensarbetet har varit att bidra med djupare analys av växthusutbyggnad utifrån teori och att med en landskapsarkitektonisk vinkling rekommendera placering och utformning av utbyggnad inom ett avgränsat projektområde. Systemtänkande och ekosystemtjänster undersöktes först teoretiskt i en litteraturstudie och applicerades sedan praktiskt i en fallstudie. Litteraturstudien visar att systemtänkande baseras i en vetenskaplig teori, systemteori, som influerat flertalet discipliner och även påverkat teori inom landskapsarkitektur. Landskapet kan ses som ett komplext och öppet system med flera subsystem och systemnivåer. Begreppet ekosystemtjänster (ekosystemens direkta och indirekta bidrag till människors välbefinnande) har i sin tur uppkommit för att försöka påverka och styra samhällsplanering mot beslut som möjliggör ekosystem att fortsätta ?ge? människan ekosystemtjänster. Ekosystemtjänster kan ses som komponenter i ett landskapssystem. I fallstudien applicerades teori kring landskapssystemets nivåer och ekosystemtjänster för att få kunskap om system inom projektområdet i Elleholm.

Den textila industrin, en egen värld, är nu under rampljuset som en av de största miljöpåverkande industrierna. Precis som i fallet med många andra industrier så måste textilbranschen intensivt arbeta med att minska sin negativa påverkan på miljön. Slutmålet måste vara att helt balansera uttagen och insättningarna så att man skapar en bransch som blir klimat- och miljöneutral. I denna rapport har en livscykelanalys gjorts på en underställströja från Helly Hansen tillverkad av 99 % polypropylene. Inom denna livscykelanalys har vi noggrant studerat och undersökt fakta för att hitta de processer som har den största påverkan på miljön.

The crucial factor for successful municipal climate work is that there are driving forces. Most importantly is that the senior officials and politicians in the municipality are dedicated to the cause considering that they have the power to influence and make a change. Besides proactive and committed individuals, it is necessary that the work is organized and anchored by clear and concrete documents and control systems. It is also important that the work is continuously monitored and evaluated. To collaborate with other municipalities, authorities or participate in various networks is another factor contributing to the improved climate work in the form of exchange of information, knowledge and experience.A major driving force for municipalities to improve themselves is the distribution of state aid and grants.

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

The use of fossil fuels such as coal and gas are a contributor to the global warming. The climate change is a worldwide problem with far reaching consequences that is believed to be very expensive. The United Nations has been introducing a framework convention on climate change. One component of the convention is the Kyoto protocol. The protocol is obligating the developed countries to decrease their emissions of greenhouse gases by 5.2 percent during the time period 2008-2012.

De internationella klimatförhandlingarna handlar om att hitta lösningar för att stabilisera halten av växthusgaser i atmosfären och att uppnå tvågradersmålet. För att uppnå målet finns olika utsläppsmål att sträva mot. Ett är ett utsläppstak där varje land inte får släppa ut mer än 2 ton CO2-ekv/capita per år för att tvågradersmålet ska uppnås. Ett annat utsläppsmål är att minska de nationella utsläppen med en viss procentsats. EU:s del i minskningen ligger på 80-95 % till 2050.Som en del av arbetet mot målet presenterade EU i mars 2011 en färdplan för ett utsläppsnålt samhälle.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

In organic animal production, synthetic amino acids are not allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as nitrous oxide (N2O), which is a very potent greenhouse gas. The emission of N can be reduced by e.g.

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.
