Cleanliness has seen a rapid increase in both developed and developing countries, along with a parallel rise in not only water and energy but also cleaning products consumed. Water and energy supply as well as dealing with waste are environmentally critical in securing a sustainable future. This dissertation aims to contribute to sustainability by providing new insights around how conventions chan
Background Clinical health promotion significantly improves treatment outcomes in hospitals and health services on both long and short term. Therefore, the World Health Organization (WHO) and the International Network of Health Promoting Hospitals & Health Services (HPH) developed and validated three easy-to-use tools that have been implemented by many national, regional and local health care
World electricity consumption is drastically increasing. One of the most common ways of producing electricity is to use the chemical energy of fossil fuels. This can be done in thermal power plants in which the chemical energy of fossil fuels such as natural gas is converted to mechanical energy and finally to electricity. Extracting the chemical energy of fuels is done through combustion of the
Reduced emissions and environmental burden from shipping are an important aim of tightening emission regulations and ambitious climate change strategy. Renewable methanol produced from biomass or from other renewable sources represents one option to face these challenges. We studied the potential of renewable methanol to offer such benefits in diesel operation in a Scania ethanol engine, which is
Even though Central Asia is water rich, water disputes have characterized the region after crumbling of the Soviet Union in 1991. The uneven spatial distribution and complex pattern of transboundary water sources with contrasting national water needs have created an intricate water dilemma. Increasing national water needs, water claims by surrounding countries, uncertainties in renewable water vol
This thesis is based on nine papers, all concerned with parameter estimation. The thesis aims at solving problems related to real-world applications such as spectroscopy, DNA sequencing, and audio processing, using sparse modeling heuristics. For the problems considered in this thesis, one is not only concerned with finding the parameters in the signal model, but also to determine the number of si
The paper deals with accuracy problems when heat energy consumption in district heating (DH) systems is calculated by measuring the DH water ow rate and its cooling. An investigation on the in uence that sizing of ow meters used has on the accuracy of DH water ow mea- surements in a typical DH subscriber station is presented. Furthermore the consequences of the choice of ow meter size on energ
There has been much debate on the topic of whether stricter environmental regulations can promote environmental performance and economic performance at the same time. Different researchers have used different indicators to measure environmental performance and economic performance in their empirical studies. However, it is a surprise that few studies have checked the relationship between environme
Housing has a rich and decades-long body of scholarship, yet geographers have only recently begun to dissect environmental and power relations in/through the home, an urgent task due to growing carbon reduction and energy efficiency targets at the heart of climate-related housing action. This paper elaborates four interconnected conceptual pathways to unpack the uneven socionatural power relations
Heat exchanger network synthesis is an essential optimisation tool for Process Integration, particularly in energy-intensive industries. Proper design or retrofit of heat exchanger network can enable energy conservation, efficiency improvement, and process debottlenecking. Many earlier pieces of research have focused on the impact of the network structure and process features such as network topol
In recent years, there has been a paradigm shift in the building sector towards more sustainable, resource efficient, and renewable materials. Bio-based insulation derived from renewable resources, such as plant or animal fibres, is one promising group of such materials. Compared to mineral wool and polystyrene-based insulation materials, these bio-based insulation materials generally have a sligh
While ecosystem service (ES) assessments become a more and more important source of knowledge, there is a need for synthesis approaches that make the results usable to support decisions. Effective synthesis approaches can reduce the information burden produced by multiple ES assessments and help decision-makers to compare alternative options and to assess their impacts. In this review, we focus on
Industrial lignin such as kraft lignin is an abundant feedstock for renewable chemicals and materials. In this study, a process was developed for depolymerization of kraft lignin followed by an upgrading separation step and further bioconversion of the obtained monoaromatic compounds to muconic acid. First, industrial kraft lignin, Indulin AT, was processed into a guaiacol-rich stream using base-c
Biofuel is a crucial renewable and environmentally friendly energy source for addressing greenhouse gas emissions and other energy-related issues. Biodiesel and butanol, among alternative biofuels, possess complementary physical and chemical properties, offering multiple possibilities for their use in existing internal combustion engines. However, biodiesel's distinctly different physical and comb
With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. These undesirable consequences of fossil-based plastics have sparked a significant interest in develo
