Societetsparken i Norrtälje : nulägesanalys och utvecklingsförslag
The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.
Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie
The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.
Påverkar tidighetstyp fiberhalten hos rödklöver?
The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.
Fr?n rapportering till transformering: H?llbarhetskonsulters perspektiv p? CSRD:s potential till h?llbar verksamhetsomst?llning
Humanity faces a major challenge with the climate and environmental crisis, largely driven by
reckless recourse use and greenhouse gas emissions by corporations. The EU?s Corporate
Sustainability Reporting Directive (CSRD) aims to standardise corporate sustainability
reporting, making practices more transparent and comparable. This directive seeks to enhance
sustainability practices and guide market forces towards sustainability, supporting the EU?s
goal of net-zero emissions by 2050.
Vem köper KlimatEl och varför? : Kvantitativ undersökning av Kalmar Energis elhandelskunder
Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.
Den svenska kärnkraftsdebatten i skuggan av Fukushima : En studie i hur svenska kärnkraftsförespråkare i maktposition använder argumentation och auktoritet
Aim: The nuclear accident in Fukushima, Japan, raised global criticism against nuclear power. In Sweden, the criticism has not been very visible and the government now allows a renewal of the nuclear power plants. The purpose with the study is to have a closer look on how Swedes in position of power motivate their positive attitude to nuclear power and how they conduct themselves to each other and to their opponents. The rhetorical perspective will be in focus for the analysing.Method: Four different artifacts represented by Swedes in position of power having a positiveattitude to nuclear power were chosen. Three rhetorical theories (the rhetorical arena, stasis andethos, pathos and logos) were used with the research question in focus.Result & Conclusions: The analyses resulted in conclusions about the strategies used by the participants such as: the importance of contexts, meaning for example that the greenhouse effect legitimizes nuclear power as a source of energy with important benefits.
Gaspotentialen i en deponi, idag och i en framtid :
Deposited waste material degrades within a short period in anaerobic environments. The
methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas.
In this thesis the amount of produced methane gas at the landfill at Örebro has been
calculated. Estimations have also been made of the amount of methane gas that might be
produced in the landfill in the future.
En studie om konflikten mellan företags affärsstrategi och CSR-arbete i lågprishandeln
A wish for a higher standard of living has driven the rate of consumption in Sweden. Mainfocus in business is on a higher growth and profitability where some companies use a lowprice strategy to win competitive advantage. The positive consumption pattern spiral is oftendiscussed in media, while criticism is limited and often refers to the environment. In order toreduce our ecological footprint we should consume more sustainably. More and morecompanies implement CSR (Corporate Social Responsibility) in their business strategy tobecome more sustainable.
Energibalansen för ett nytt flerbostadshus i Mellansverige : Beräkningar intervjuer och analys av energikraven i Boverkets Byggregler
Abstract This degree project comprises 30 credits, i.e. 20 weeks of work. The work mainly deals with the energy balance for a multi-family house in Västerås and the requirements for energy conservation in the Swedish building code, BBR. Calculations of the energy balance are supplemented by a number of interviews. Energy conservation in general has become more important in recent years and the subject is in line with increased public awareness. This importance and attention is explained by environmental problems in general and global warming in particular, but also by rising energy prices.
The efficiency of the newly launched predatory mite Amblydromalus limonicus : biological control of thrips in cucumber
In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been
examined for its potential to use as a biological control agent in cucumber production. A. limonicus
can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci.
Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the
southern part of Sweden. The basic control agent used against thrips was the predatory mite
Amblyseius swirskii. In selected areas, additional A.

To practice corporate responsibility : a study of how Swedish food retailers practice strategic corporate responsibility for image differentiation
Due to the increase of the emission of greenhouse gas and climate changes more and more customers demand environmentally sustainable products. The increased demand of sustainable products from cradle to grave is something that has affected the food sector. Many retailers within the food sector feel that they are less or more forced to be environmentally friendly. Nowadays many retailers have chosen to show customers and stakeholders that they want to ?do good? by publishing annual sustainability reports.
The Swedish food market has been one of many markets investing in being environmentally friendly.
Användarrelaterad energieffektivisering : En studie på länssjukhuset i Sundsvall
Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.
