Stockholms Energiframtid : En backcastingstudie för ett fossilbränslefritt Stockholms län 2050

This study concerns the energy future of the county of Stockholm up until 2050 and describes how the energy consumption can be compared to today with the use of scenario methodology. Within energy future studies the backcasting approach is well known and has been put to use in this study. Due to the characteristics of backcasting the study is self-fulfilling, i.e. the future energy scenarios presented in this study satisfy the targets set up in this study. In the light of what may be the largest challenge of our time ? the climate change - the aim of this study is to describe how the energy consumption in a fossil fuel free Stockholm county in the year of 2050 may be.

Uthållig sanitet : en förstudie i staden Picota, Peru

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

The state of the Latvian wood pellet industry : a study on production conditions and international competitiveness

In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production. The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.

Industriell symbios som affär : Hur kan ett återvinningsföretag facilitera utvecklingen av regionala industriella ekosystem?

Addressing increasing global environmental problems requires greater resource efficiency, and one way of working towards this is through industrial symbiosis. Industrial symbiosis means that companies collaborate through sharing of resources for collective benefits. The documented benefits of working with industrial symbiosis indicate that there is potential for companies to operate commercially with facilitation of industrial symbiosis. An interesting company to study within this context is Econova. Econova operates within the recycling and gardening industry and has been identified as a possible catalyst for industrial symbiosis.

Post-harvest losses in fruit supply chains : a case study of mango and avocado in Ethiopia

Food insecurity is a great problem worldwide and Ethiopia is one of the sub-saharan countries that are suffering from poverty and food insecurity and a large part of the population are living in a state of undernourishment. To reduce these problems, a successful horticulture production can be an important factor. Compared to other crops, fruit production in Ethiopia has not been a large part of the agricultural sector. However, the demand on the domestic market is increasing as well as the production for avocado and mango. To increase food security it is important to focus on ways to decrease post-harvest losses of food products and not only have the productivity of agriculture in focus.

Utmaningar och hinder i gränsöverskridande transportinfrastrukturplanering : En studie av TEN-T med Nordiska triangeln som exempel

Flera saknade länkar i Europas transportnät definierades på mitten av 1980-talet som nödvändiga att bygga för att bidra till att uppnå de EU-politiska målen om fri rörlighet inom gemenskapen, större och jämnare transportflöden inom och mellan medlemsstaterna, ekonomisk tillväxt, en friktionsfri och välfungerande inre marknad, hållbar utveckling samt territoriell, social och ekonomisk sammanhållning.EU och medlemsstaterna initierade mot denna bakgrund transportinfrastrukturprogrammet "Trans-European Networks for Transport", eller det transeuropeiska transportnätverket (TEN-T) på svenska, som en följd av Maastrichtfördraget 1992.I Norden ska den s.k. Nordiska triangeln, som både har pekats ut som ett särskilt prioriterat transportinfrastrukturprojekt i de nu gällande och sannolikt inom kort i de nya EU-riktlinjerna för TEN-T, bidra till att uppnå de ovanstående politiska målen. Syftet med projektet är att sammanbinda Norge, Sverige, Danmark och Finland via uppgraderade och gränsöverskridande vägar, järnvägar och maritim infrastruktur. Förutom att projektet anses förbättra förbindelserna för gods och passagerare inom Norden, skapas bättre möjligheter för större och snabbare transportflöden till och från Centraleuropa, Ryssland och de baltiska länderna.Det västra benet i den Nordiska triangeln, dvs. korridoren Oslo-Göteborg-Köpenhamn, har varit föremål för diskussion sedan 1980-talet då en högklassig motorväg, järnväg samt en fast förbindelse över eller under Öresund och Fehmarn Bält föreslogs av "European Round Table of Industrialists".Syftet med infrastrukturpaketet var att förbättra transportinfrastrukturen inom korridoren samt få en fast förbindelse till kontinenten.

An assessment of public procurement of timber buildings : a multi-level perspective of change dynamics within the Swedish construction sector

The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.

Humanurin till åkermark och grönytor : avsättning och organisation i Göteborgsområdet

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

Johannishusparken : historia, nutid, framtid

Summary The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding Infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.

Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.
