Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter presents the methodology employed for the Integrated Socio-Economic Assessment (MISEA) of different designs of Multi-Use Offshore Platforms (MUOPs). The methodology allows for the identification, the valuationand the assessment of the potential impacts and their magnitude. The analysis considers a number of feasible designs of MUOP investments, and the likely responsesof those impacted by the investment project. The approach provides decision-makers with a valuable tool to assess whether a MUOP project increases the overall social welfare and hence should be undertaken. This is performed under alternative specifications regarding platform design, the discount rate and the stream of net benefits, if a Cost-Benefit Analysis (CBA) is to be followed or a sensitivity analysis of selected criteria in a Multi-Criteria Decision Analysis (MCDA) framework. Themethodology can support the implementation of policies aiming at achieving a goodenvironmental status of the EU’s marine waters and the protection of the resource base upon which marine-related economic and social activities depend.

Tidskriftsartikel (refereegranskat)abstract
- The ForMAX beamline at the MAX IV Laboratory provides multiscale and multimodal structural characterization of hierarchical materials in the nanometre to millimetre range by combining small- and wide-angle X-ray scattering with full-field microtomography. The modular design of the beamline is optimized for easy switching between different experimental modalities. The beamline has a special focus on the development of novel fibrous materials from forest resources, but it is also well suited for studies within, for example, food science and biomedical research.

- The effects of surface roughness on production of steel sheet are critically reviewed. New developments in the measurement and characterisation of surface roughness seem likely to improve our understanding of its effect on sheet metal production. Much useful information can still be acquired by 2D techniques but increasingly the evidence is that sheet metal surface roughness is better measured and characterised by 3D methods. The facility for direct surface visualization in 3D is shown to be particularly helpful. When measuring 3D the measurement area size and sampling space are critical and for evaluation the filtering of surface data into roughness and waviness is more complicated than for 2D profiles.

On-line estimation of nitrification and denitrification capacity at Avedøre wastewater treatment plant
- 2004
-
Konferensbidrag (refereegranskat)abstract
- In this paper, on-line nitrification and denitrification rate estimation in an alternating wastewater treatment plant is discussed. The nitrification/denitrification rates are estimated on-line using continuous measurements of ammonia and nitrate. From the rate estimates, the plant capacity is derived. This information is useful in various ways: for early warning to prevent severe disturbances such as nitrification inhibition; for optimising phase lengths and distribution of the phases in the alternating operation; and directly for the control system of the treatment plant. The estimation is based on the derivatives of the measurement signals combined with a simplified model of nitrogen dynamics of the plant. In the paper, we show examples of a successful application of the estimation methods to full-scale operation of the treatment plant and are today incorporated in the control system.

Tidskriftsartikel (refereegranskat)abstract
- European seas are encountering an upsurge in competing marine activities and infrastructures. Traditional exploitation such as fisheries, tourism, transportation, and oil production are accompanied by new sustainable economic activities such as offshore windfarms, aquaculture, and tidal and wave energy. One proposed solution to overcome possible competing claims at sea lies in combining these economic activities as part of Multi-Use Platforms at Sea (MUPS). MUPS can be understood as areas at sea, designated for a combination of activities, either completely integrated in a platform or in shared marine space. MUPS can potentially benefit from each other in terms of infrastructure, maintenance, etc. Developing MUPS in the marine environment demands adequate governance. In this article, we investigate four European sites to find out how governance arrangements may facilitate or complicate MUPs. In particular, we apply a framework specifying policy, economic, social, technical, environmental, and legal (PESTEL) factors to explore governance arrangements in four case study sites in different sea basins around Europe ( the Mediterranean Sea, the Atlantic Ocean, the North Sea, and the Baltic Sea). The article concludes with policy recommendations on a governance regime for facilitating the development of MUPS in the future.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- A 600 MW offshore wind farm is under construction in the Netherlands Exclusive Economic Zone at a site called Gemini situated 55 km north of the Wadden Sea island of Schiermonnikoog and 85 km from the nearest Dutch port ofEemshaven. This chapter investigates the option of introducing a multi-use design for the Gemini site by adding mussel cultivation (48 kt wet weight per year) andseaweed cultivation (480 kt wet weight per year) to the wind farm. An institutional analysis indicates a political will in the Netherlands to support the development ofadding uses to offshore wind farms, but a number of implementation obstacles are also identified. Those obstacles include an absence of licences for multi-use production and legal restrictions against third-party access to wind farms. There istherefore a need for a regulatory framework for multi-use and trust-building amongactors involved in multi-use installations. A financial and economic assessment,and a cost-benefit analysis also taking into account monetized changes in CO2 emissions, indicate that adding mussel cultivation to the wind farm is likely to be both financially and socio-economically viable. Including a seaweed cultivation function is probably not financially and socio-economically viable under currenttechnical and economic conditions. Knowledge gaps and uncertainties in these assessments with respect to, for example, missing site-specific data and non-monetizedexternalities suggest further research, also including pilot cultivations of mussels and seaweed in planned single-use or multi-use installations.

Cirkulär hantering av förorenade massor. Utveckling av metod för ökad återvinning

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Land development, land remediation and infrastructure projects deal with large quantities of contaminated soil masses. Only a small part of the masses is recycled after treatment and a large part is deposited. At the same time, large quantities of new soil and rock materials must be quarried for construction work. An increased recycling of contaminated masses that is environmentally sound and safe from a human health perspective would make an important contribution to the improved resource management that characterizes a circular economy. This would lead to reduced transports, reduced volumes of deposited waste and a more sustainable management of contaminated masses. The project has analyzed various instruments in society with a view to examining the obstacles and opportunities for increased recycling of contaminated soil masses. The socio-economic benefits to society with an increased recovery of contaminated soil masses have been described in general terms. A method has been developed to provide different actors with a tool for classifying the suitability of soil masses for environmentally- and health-safe reuse. Such a method provides greater competitiveness of entrepreneurs with the ability and knowledge to carry out such recycling. The overall conclusion of this work is that there are significant potential socio-economic benefits from an increased recovery of contaminated soil masses. Several possible measures have been identified that could be useful to lead to an increase in the recovery of contaminated soil slabs in society: • Better adaptation of the environmental quality requirements of soil masses to the actual land use of the area where recycled masses can be potentially used • Reduced administration for using recycled masses • Increase the allowed storage time before disposal • Increase the requirements for treatment of masses before disposal • Introduce taxes on masses that are possible to pre-treat before disposal • Introduce landfill tax and increase landfill fees for inert soil masses • Increased on-site treatment (in situ and ex situ) • Introduce more innovative procurement and choice between execution or turnkey contracting • Calculate key figures for the recycling of contaminated soil masses • Develop and apply a standardized and well-founded classification of different the environmental and technological potential of masses for recycling. A proposed method has been developed and described in this study. Recycling of soil masses thus requires consideration of a variety of factors. The focus of the classification methodology developed here is on the environmental and technical characteristics of the soil mass. However, as described above, for the soil mass to be recycled also conditions other than the environmental and technical characteristics of the masses need to be fulfilled. We therefore propose that the classification of soil masses be seen as part of a step-by-step process in which different actors in society must act in order for increased recycling to be possible. We propose that the step-by-step process of circular management of contaminated masses, as well as for other types of waste, should, as far as possible, be based on the so-called “waste hierarchy”. In order to promote an increased degree of recycling, some efforts have been proposed that different actors can implement within the different levels of the waste hierarchy. It has not been possible to carry out a full analysis of opportunities for the various actors, but the proposals should be seen as a basis for a further development.

What's the point? The contribution of a sustainability view in contaminated site remediation

Tidskriftsartikel (refereegranskat)abstract
- Decision support tools (DST) are often used in remediation projects to aid in the complex decision on how best to remediate a contaminated site. In recent years, the sustainable remediation concept has brought increased attention to the often-overlooked contradictory effects of site remediation, with a number of sustainability assessment tools now available. The aim of the present study is twofold: (1) to demonstrate how and when different assessment views affect the decision support outcome on remediation alternatives in a DST, and (2) to demonstrate the contribution of a full sustainability assessment. The SCORE tool was used in the analysis; it is based on a holistic multi-criteria decision analysis (MCDA) approach, assessing sustainability in three dimensions: environmental, social, and economic. Four assessment scenarios, compared to a full sustainability assessment, were considered to reflect different possible assessment views; considering public and private problem owner perspectives, as well as green and traditional assessment scopes. Four real case study sites in Sweden were analyzed. The results show that the decision support outcome from a full sustainability assessment most often differs to that of other assessment views, and results in remediation alternatives which balance trade-offs in most of the scenarios. In relation to the public perspective and traditional scope, which is seen to lead to the most extensive and expensive remediation alternatives, the trade-off is related to less contaminant removal in favour of reduced negative secondary effects such as emissions and waste disposal. Compared to the private perspective, associated with the lowest cost alternatives, the trade-off is higher costs, but more positive environmental and social effects. Generally, both the green and traditional assessment scopes miss out on relevant social and local environmental secondary effects which may ultimately be very important for the actual decision in a remediation project.
