    Självkörande bussar i stadstrafik - förstudie2018Report (Other (popular science, discussion, etc.))
    Abstract [en]

    Automated road transport is regarded as a key enabler for sustainable transport. One example is the use of small automated buses as a supplement to already existing public transport services. There are several manufacturers of these kind of buses, and field trials are in progress.

    The goal of the pre-project is to evaluate the feasibility and criteria for transport with automated buses in two middle-sized Nordic municipalities, Lørenskog in Norway and Borås in Sweden, by analyzing at least two different test-cases in each location. Feasibility, adaptation to existing traffic and conditions for public acceptance are described. The pre-project concludes that automated buses are possible in these two municipalities. Further test and demonstrations should be made.

    SARDOS: Self-Adaptive Reaction against Denial of Service in the Internet of Things2018Conference paper (Refereed)
    Abstract [en]

    Denial of Service (DoS) is a common and severe security issue in computer networks. Typical DoS attacks overload servers with bogus requests, induce them to worthlessly commit resources, and even make them unable to serve legitimate clients. This is especially relevant in Internet of Things scenarios, where servers are particularly exposed and often equipped with limited resources. Although most countermeasures focus on detection and mitigation, they do not react to dynamically adapt victims' behavior, while at the same time preserving service availability. This paper presents SARDOS, a reactive security service that leverages detection mechanisms from different communication layers, and adaptively changes the operative behavior of victim servers while preserving service availability. We experimentally evaluated SARDOS with a prototype implementation running on an underclocked Raspberry Pi server. Our results show that, when running SARDOS, a server under attack displays considerably lower memory and CPU usage, while still ensuring (best-effort) fulfillment of legitimate requests.

    Improved glass bonding with plasma treatment2018In: Applied Adhesion Science, ISSN 2196-4351, Vol. 6, no 9Article in journal (Refereed)
    Abstract [en]

    Bonding of automotive glass is generally performed with 1C PUR adhesive on a primedceramic frit or naked glass surface. The aim of this research was to replace the chemistryof the primer with an atmospheric pressure plasma treatment (APPT) with compressedair for cleaning and activation directly before bonding. Characterization of theglass surface was performed with surface energy through contact angle, XPS, TOF-SIMSand adhesive peel bead test. The results show that APPT treatment can clean the surface,improve the wetting, improve the bonding but reduce the number of non bridgingoxygen for the adhesive to bond to. The highest measured spot temperature of theglass during APPT was measured up to 270 °C, but the temperature was depending onprocess parameters. A reduction in non bridging oxygen was also seen during heatingof the reference glass at 100 °C. A further reaction was seen when measured aftera 550 °C heating. A modified APPT treatment with deionized water as precursor wasused. The results show that the APPT with water does not lower the level of non bridgingoxygen and the bonding was further improved.

    New certification system for enhanced fire safety of vehicles2018In: Proceedings of 7th Transport Research Arena TRA 2018, 2018Conference paper (Other academic)
    Abstract [en]

    RISE has initiated and developed a certification scheme for the vehicle industry that will enable manufacturers, operators and service centres (workshops) to certify their fire risk mitigation process. The fire risk management required in the certification is a key safety element, used to identify and evaluate fire hazards. For best results, it is important that manufacturers, operators and service centres are equally dedicated to solve the fire problem. Vehicle fire investigations reveal that design, production, operation and maintenance can all be responsible, however, most important is to ensure that information and experiences from fire incidents and identified fire hazards are linked to relevant personnel, practices, manuals, and quality procedures. The certification cannot guarantee the elimination of vehicle fires, but can ensure that manufacturers, operators and service centres will operate at the front line of vehicle fire safety engineering.

    Metoder för att testa dukar och membran i tunnlar och bergrum2018Report (Other academic)
    Abstract [en]

    Tunnel and rock lining systems are used for drainage and icing protection. These systems can consist of any combination of concrete, metal, plastic or textile. The report summaries the available methods, both for testing and for installation. The large variation in both systems and test methods often make it difficult for constructors or designer to understand the importance of different methods. The report gives indication of what type of linings exists and how to ensure the fire safety of such systems. Fire safety properties can be verified in three different ways: #1 Full systems can be tested in full scale fire tests, #2 a section of the system can be tested in standardized furnace tests, or #3 plastic and/or textile membrane can be tested with regards to requirements on fire spread. It is suggested to require that a fire should not be able to propagate in the system. This can be verified with #3 above requiring class B, C or D according to EN 13501-1. If the lining system offers structural fire protection, it can be verified suing #2 above.

    Analysis of 985 fire incidents related to oil- and gas production  on the Norwegian shelf2018In: Safety and Reliability: Safe Societies in a Changing World / [ed] Stein Haugen, Anne Barros, Coen van Gulijk, Trond Kongsvik, Jan Erik Vinnem, 2018, Vol. 1Conference paper (Refereed)
    Abstract [en]

    Fire is a major threat in the petroleum industry. However, little has been published about the fire related incidents that have occurred in the Norwegian petroleum sector. To gain more knowledge, data from 985 incidents in the 1997 - 2014 period has been analysed. Examples of factors studied are type of facility involved, involved area or system, consequences and severity level. The analysis of the fire incidents reveals that even though many incidents are reported, the large majority of these have not imposed risks for severe fire accidents. It has also provided valuable information regarding possible dangerous situations, commonly in-volved areas, types of equipment as well as types of activity that were involved. Twenty-nine percent of the incidents were false alarms, which must be regarded as a high number in an industry where any production stop could be extremely costly.

    Organic-inorganic hybrid planarization and water vapor barrier coatings on cellulose nanofibrils substrates2018In: Frontiers in Chemistry, E-ISSN 2296-2646, Vol. 6, article id 571Article in journal (Refereed)
    Abstract [en]

    Cellulose nanofibrils (CNF) can be produced in the form of thin, transparent andflexible films. However, the permeability of such materials to oxygen and water vaporis very sensitive to moisture, which limits their potential for a variety of packaging andencapsulation applications. Diffusion barrier coatings were thus developed to reducethe access of water molecules to enzymatically pre-treated and carboxymethylated CNFsubstrates. The coatings were based on UV curable organic-inorganic hybrids withepoxy, tetraethylorthosilicate (TEOS) and 3-glycidoxypropyltrimethylenesilane (GPTS)precursors and additional vapor formed SiNx layers. A total of 14 monolayer andmultilayer coatings with various thickness and hybrid composition were produced andanalyzed. The water vapor transmission rate (WVTR) of the bilayer epoxy/CNF film wastwo times lower compared to that of uncoated CNF film. This was partly due to the watervapor permeability of the epoxy, a factor of two times lower than CNF. The epoxy coatingimproved the transparency of CNF, however it did not properly wet to the CNF surfacesand the interfacial adhesion was low. In contrast hybrid epoxy-silica coatings led to highadhesion levels owing to the formation of covalent interactions through condensationreactions with the OH-terminated CNF surface. The barrier and optical performance ofhybrid coated CNF substrates was similar to that of CNF coated with pure epoxy. Inaddition, the hybrid coatings provided an excellent planarization effect, with roughnessclose to 1 nm, one to two orders of magnitude lower than that of the CNF substrates.The WVTR and oxygen transmission rate values of the hybrid coated CNF laminateswere in the range 5–10 g/m2/day (at 38◦C and 50% RH) and 3–6 cm3/m2/day/bar (at23◦C and 70% RH), respectively, which matches food and pharmaceutical packagingrequirements. The permeability to water vapor of the hybrid coatings wasmoreover foundto decrease with increasing the TEOS/GPTS ratio up to 30 wt% and then increase athigher ratio, and to be much lower for thinner coatings due to further UV-induced silanolcondensation and faster evaporation of byproducts. The addition of a single 150 nmthickSiNx layer on the hybrid coated CNF improved its water vapor barrier performance bymore than 680 times, with WVTR below the 0.02 g/m2/day detection limit.

    Planetary Boundaries analysis for Houdini Sportswear – a Pilot Study: Assessment of company performance from a planetary boundaries perspective2018In: Planetary Boundaries Assessment 2018 – This is Houdini, Houdini Sportswear , 2018, p. 37-66Chapter in book (Other (popular science, discussion, etc.))
    Abstract [en]

    This is to our knowledge the first ever corporate Planetary Boundaries analysis. It is an explorative collaboration between Houdini Sportswear, Albaeco and Mistra Future Fashion with the long-term ambition to create an open-source approach that will provide Houdini and other similar companies with a more holistic view on their sustainability efforts. Albaeco is closely tied to the Stockholm Resilience Centre (SRC), an international research centre for sustainability science at Stockholm University, known among other things for its work on planetary boundaries, resilience and ecosystem services.

    This report aims to operationalize the Planetary Boundaries framework in a business context. The framework was established in 2009 when a group of scientists (Rockström and others, 2009) identified nine global environmental boundaries we should remain within so that our societies can continue to develop in a positive way. As such the Planetary Boundaries provide a holistic way of analysing sustainability that has acquired international recognition and contributed to the UN’s Sustainable Development Goals (SDGs). Rather than a narrow focus on for example water, chemicals or energy use, a planetary boundaries approach implies covering a larger set of critical environmental factors.

    The manufacturing and consumption of clothes, like every other industry, plays a role in relation to all of the nine boundaries. For example, cotton is one of the most pesticide and water demanding crops grown; chemicals used when treating fabrics risk polluting water downstream from factories; and shell layer garments are often produced using compounds that stay in the environmental indefinitely and accumulate in the fatty tissues of wildlife and humans

    Albaeco, Houdini and Mistra Future Fashion believe that analysing the textile industry from a Planetary Boundaries perspective is an important part of a larger ambition to integrate scientific analysis and resilience thinking into projects focused on accelerating business solution for sustainability.

    Possible toxicological effects of nanocellulose: an updated literature study, No. 22017Report (Other academic)
    Abstract [en]

    This literature review covers open publications and reports on the subject of nanocellulose and its possible toxicological effects. There is currently a rather low number of peer reviewed articles on the subject. However, from the articles reviewed, caution of inhalation of nanocellulose would be recommended since in vivo tests have shown immunotoxicity effect on lungs even though residues of other production chemicals, biocides and endotoxins from bacterial contamination might affect the results.

    Drop Performance of Dangerous Goods Packages in the Aspect of Parcel Delivery Standards2018In: Packaging: Driving a sustainable future, 2018, p. 569-577Conference paper (Refereed)
    Abstract [en]

    Requirements for dangerous goods packaging are well known, whatever version are used. The testing circumstances are strictly defined for each transportation method (road, rail, air, sea). But nowadays it is becoming a practice that courier express operators transport dangerous goods as single package. This parcel delivery method means a higher risk for all kind of logistics participants. By this service the packages are delivered fast, but handled more roughly than in comparison to LTL (less than truckload) or FTL (full truck load). Naturally, the parcel delivery sector uses its own suitability testing methods, which are also well defined. These procedures are coming from various standards such as ASTM, ISTA or corporate (FedEx) standards.This paper compares the most common parcel delivery testing conditions concerning the drop test requirements of DGR (Dangerous Goods Regulation) using packaging such as paper bag, corrugated fibreboard box, steel drum and plastic jerrycan, respectively. Then the test results were analyzed to present the differences.

    Water-free bonding of corrugated board2018In: Packaging: Driving a sustainable future / [ed] Wang S-W, 2018, p. 608-616Conference paper (Refereed)
    Abstract [en]

    The "water-free bonding of corrugated board" concept focuses on thedevelopment, waste management and market potential of a new corrugated board production method. It has earlier been shown that by integrating PLA into paper, certain mechanical properties of corrugated board papers can be enhanced. These enhanced papers have been used for producing corrugated board. Corrugated board is usually produced by gluing the corrugated board paper layers with a starch suspension. This process is reducing the mechanical paper strength and is also energy consuming, as the water added by the starch suspension in the process has to be evaporated. In this study, two new water-free joining techniques for corrugated board have been investigated: PLA-welding, which melts the inherent PLA of the paper to create a bond and using PLA as an adhesive. Both techniques have shown promising results and are recommended for further investigation, however, replacing starch glue with PLA seems to be a solution closer to the market. For the material to fit in a future circular economy it is important that the waste is managed in a way that is sustainable for the environment and the society. Repulp ability testing in combination with literature studies indicate that the new material would be possible to recycle, and that the new material could function in every step described in the EU Waste Framework Directive.

    A Study of the Interplay Between Safety and Security Using Model-Implemented Fault Injection2018Conference paper (Refereed)
    Abstract [en]

    The combination of high mobility and wireless communication in many safety-critical systems have increased their exposure to malicious security threats. Consequently, many works in the past have proposed solutions to ensure safety and security of these systems. However, not much attention has been given to the interplay between these two groups of nonfunctional requirements. This is a concern as safety solutions may negatively impact system security and vice versa. This paper addresses the interplay between safety and security by proposing an attack injection framework, based on model-implemented fault injection, suitable for model-based design. The framework enables us to study and evaluate the impact of cybersecurity attacks on system safety early in the development process. To this end, we have implemented six attack injection models and conducted experiments on Simulink models of a CAN bus and a brake-by-wire controller. The results show that the security attacks modeled could successfully impact the system safety by violating our defined safety requirements.

    Separatförbränning av utvalda avfallsfraktioner för ökat resursutnyttjande av aska2017Report (Other academic)
    Abstract [sv]

    Avfall som går till förbränning innehåller olika mängder metaller beroende på vilken typ avfall det är. Idag blandas avfallet innan förbränningen för att ge en bränslemix som erbjuder hög energieffektivitet och hög tillgänglighet på anläggningen. Denna blandning av olika avfall innebär samtidigt att metallhalterna i askorna blir relativt låga, vilket gör det svårt att återvinna dem.

    Genom att ackumulera specifika avfallsfraktioner över tid och kampanjelda dessa ökar möjligheterna att återvinna metallerna i askorna mer kostnadseffektivt. Detta måste dock ske med bibehållen energieffektivitet och tillgänglighet, vilket kräver god kunskap om olika avfallsströmmars egenskaper vid förbränningen. För en av anläggningarna i detta projekt skulle en sådan förändring i driftstrategi kunna innebära en ökad metallåtervinning (Cu, Zn, Mn) med 2400 ton , utan några förändringar i företagets mix av mottagana avfallsströmmar (sett över helåret).

    Olika avfall har olika möjligheter och utmaningar. Exempelvis kan en avfallsström ha höga metallhalter men kan samtidigt förknippas med höga underhållskostnader och driftproblem i form av ökad korrosion och beläggningsbildning i anläggningarna. Under projektet har sådana möjligheter och utmaningar beaktats för ett flertal metallrika avfall som exempelvis kretskort, däck, kompositmaterial, färgrester, returträ, slam, och SLF (en fraktion från återvinning av bilar och vitvaror). De tre sistnämnda pekades ut som extra intressanta ur branschsynpunkt då det finns stora volymer av dem tillgängliga på marknaden.

    När man i projektet har diskuterat möjligheter och utmaningar så har mycket av fokus avseende utmaningarna varit kring bränsleberedning, lagring och förbränning medan möjligheterna främst varit fokuserade på den ökade metallåtervinningen och avgiftningen av askorna (samt även i viss mån de positiva effekterna som exempelvis vissa slam kan ha när de eldas tillsammans med andra avfallstyper). En viktig del för att låsa upp den potential som finns med samförbränningen är också den efterföljande metallutvinningsprocessen. En ansökan om fortsättning har därför lämnats in kring ett innovationsprojekt där fullskaliga förbränningsförsök planeras tillsammans med pilotförsök för själva metallutvinningen.

    Ett tydligt resultat från projektet är att det saknas kunskap om innehållet i många avfallsströmmar, eller kanske snarare just om innehållet av värdemetaller i olika avfallsströmmar. Det finns också brister i kunskaperna kring vilka tekniska utmaningar och risker som kan förknippas med att förbränna en större andel av en särskild avfallsström. Dessa osäkerheter bidrar till trögheten i att förändra driften, då de ekonomiska konsekvenserna av oförutsedda stopp i förbränningsanläggningen kan vara mycket stora.

    HiFi Radar Target: High fidelity soft targets and radar simulation for more efficient testing (real and virtual)2018Report (Other academic)
    Abstract [en]

    The 77 GHz radar is a crucial sensor in the Advanced Driver Assistance System (ADAS) and Autonomous Driving (AD) system due to its ability to detect and track objects at distances up to 200 meters. To ensure high reliability of the radar function, extensive testing with soft surrogate targets is needed. However, the radar response of a surrogate target may differ from that of real targets, causing unexpected reactions of the ADAS and AD functions in real traffic situations. The first project goal was therefore to develop and validate realistic soft surrogate targets, a work which was performed in several steps. First radar reference targets were designed and verified. Secondly procedures for calibration of automotive radars were developed. Finally, a thorough investigation on Radar Cross Section (RCS) characterization methods for large test objects on the test track was conducted resulting in several measurement setups and measurement procedures including uncertainty analysis. Now, with the ability to perform repeatable and reliable RCS characterizations, several real and surrogate targets were characterized and work on improving RCS profile of surrogate targets were conducted.Strong competition in the automotive industry and the need to validate more and more complex functions (including autonomous drive) drives the development of virtual test methods. The ability to test the ADAS or AD functions virtually early in the development will save considerable time and cost. However, there were no such tools available with full radar simulation in-loop available prior to the project, which was the reason for the second goal of this project: an ADAS/AD system simulation tool-chain with radar simulation in-loop.The HiFi Radar Target project (diarienr. 2015-04852) was an FFI project within the Electronics, Software and Communications program. After prolongation it was a 30-month project that started 2015-12-31 and ended 2018-06-30. The project had a total budget of 15.9 MSEK.

    Seafood Life Cycle Inventory database : Methodology and Principles and Data Quality Guidelines2018Report (Other academic)
    Abstract [en]

    An increasing awareness about the important role of food, in particular animal-based foods including seafood, for global environmental impacts has led to a need of producers as well as retailers to communicate environmental impacts of raw materials and products through the food chain. This is demonstrated by new requirements to document the environmental footprints of products, e.g. by certification schemes and policies. The EU policy for sustainable development with its "single market for green products" is one example, aiming for documenting the environmental footprint of products on the EU market according to the Product Environmental Footprint (PEF) method. The goal is to enable consumers, retailers, producer, regulators and policy makers to make conscious choices and establish drivers for reducing environmental impacts throughout product supply chains.

    To be able to live up to these new requirements, representative data of high quality is needed, something which has largely been missing for seafood products. To make high-quality, representative data on the resource use and environmental impacts caused by seafood products (including biomass used directly or indirectly for feed) available, the Norwegian seafood industry initiated a pilot project. The project defined a recommended method and structure for data collection and used this method to collect available data for a number of pilot cases. The method for data collection is presented in this document and can, together with the pilot data sets made available through the project, be used by the industry as a basis for a broader data collection to create an expanded seafood LCI database.

    Screening test methods for determination of fire spalling of concrete2018Report (Other academic)
    Abstract [en]

    The fire resistance of concrete structures is generally good, but for some types of concrete fire spalling can reduce the fire resistance significantly. Therefore, methods are needed to predict whether a concrete will spall when exposed to fire and the severity of spalling.

    The objective of the present project was to develop an intermediate scale test method for the evaluation of the spalling behavior of concrete. The test method shall be cost effective and enable screening of different concretes before a full scale approval test is performed. A number of different intermediate scale test methods have been evaluated regarding the precision to reproduce the spalling behavior of that observed in full scale tests.

    Of the different test specimen shapes and methods, a circular test specimen where the concrete is casted in a steel tube has shown the best correlation to the full scale tests performed. This specimen is easy to produce, and the fire test can be performed on a small furnace.

    Sänkning av kväveoxidemissioner samt förlängd livslängd genom rökgasåterföring i en pelletsbrännare 750 kW2017Report (Other academic)
    Abstract [en]

    The project has been involved in developing a flue gas recirculation system aimed at reducing emissions of NO

    x and dust, as well as extending the life of the material in a pellet burner. Installation of a flue gas recirculation system and combustion tests have been performed in a laundry in Bengtsfors, which has a pellet-fired boiler with two janfire burners of 750 kW each. The results of the tests showed that the flue gas recirculation had an impact on NOx emissions. These decreased by about 17-18% in wood pellets combustion and by 10% in combustion of nitrogen rich agro fuel pellets in comparison to non-flue gas recirculation. With flue gas recirculation, the combustion furnace temperatures decreased by 85-105 oC for wood pellets and about 70 oC for agro fuel pellets.

    Tekniska och ekonomiska förutsättningar för oljeersättning i industrin med pyrolysolja2017Report (Other academic)
    Abstract [en]

    For potential users, especially in the industry, which consider bio-oil as well as pyrolysis oil as a fuel alternatives in the future, in-depth knowledge of its technical and economic conditions in various industrial applications is required. To verify which requirements these oils sets on the combustion technology more combustion tests in potential burners are needed to clarify any technical development. To minimize any problems that may arise with pyrolysis oil, from delivery to storage and combustion, the available knowledge about the use of common bio-oils should be used. The overall objective of this project is to investigate the possibilities to use pyrolysis oil in various industrial applications.

    Fire Safety Engineering for Innovative and Sustainable Building Solutions2017Report (Other academic)
    Abstract [en]

    The Nordic fire safety engineering project for innovative and sustainable building solutions, funded by Nordic Innovation, SBUF (the Swedish construction industry's organisation for research and development) and DIBK (the Norwegian National Office of Building Technology and Administration), started in June 2014 and ended in August 2017. The aim of this project was the production of practical specifications on two areas within fire safety engineering:

    • Standard on Probabilistic Method to Verify Fire Safety Design in Buildings
    • Standard on Control in the Building Process

    What has been developed is tailored for the Nordic context which is a region that has used fire safety engineering for a relatively long time. This project supported Nordic harmonization of fire safety which in the end may facilitate trade of services and products.

    Furthermore, and in order to cover the Nordic context, all Nordic countries have been represented by at least one project partz§ner. The following table shows all the partners as well as their country of origin.

    The ultimate challenge or just common sense : The present practices and future opportunities to increase the utilization of livestock manure as organic fertilizer in North West Russia2017Report (Other academic)

    The ultimate challenge or just common sense

    The present practices and future opportunities to increase the utilization of livestock manure as organic fertilizer in North West Russia

    The risk of nutrient contamination of surface- and groundwater’s from livestock farming has been one of the issues to address in international cooperation initiatives in the Baltic Sea Region during the recent decade. In particular, international initiatives targeting North West Russia in the 2000-2010’s by HELCOM and NEFCO and as bilateral cooperation with Russia by Finland and Sweden have assessed the severity of the threat, have introduced technical solutions to process livestock manure and have explored the market potential for fertilizer products made through processing of livestock manure. However, a comprehensive resolution to the growing problem still remains a long term goal and many of the barriers to increase manure processing and organic fertilization – poor economic incentives and lack of proven cost-efficient technologies – still prevail.

    In Russia, ongoing adaptation of state support to agriculture as part of the WTO membership brings about indirect area-based farm support and increased share of support to investments in farm infrastructure, rural development and in management of health, hygienic and environmental aspects. These represent positive opportunities for increasing sustainable manure management and the proportion of manure-based fertilization. The Technological Regulations (TR) instrument introduced in 2008, enhanced enforcement and systematic introduction of BAT in Russian agriculture, provide a set of management tools which has good potential to be effective for the administration and be accepted by the agricultural companies. At the same time, there is a risk that the increasing concentration of livestock, in particular poultry production in Leningrad Oblast narrows alternative paths for sustainable manure management and is leading to a situation in which only large scale technological solutions may prove to be viable in order to solve the issue on the regional scale.

    This report reviews the current environment in North West Russian Federation to advance sustainable animal manure management and reflects this against the EU context with related examples from Latvia. The report concludes that a sustainable future for North West Russian agriculture relies on the overall sustainability of the enterprises and that regulative and subsidy measures should reinforce the positive link between economic and environmental benefit. Spatial aspects on the territorial level should be

    addressed as the location of agricultural enterprises both relative to each other and relative to human settlements have increasing importance from the perspective of environmental, health and biosecurity implications. Thirdly, Russia’s adaptation to the WTO framework, the process of implementing BAT in agriculture and the TR instrument to support holistic farm specific solutions provide a range of interesting topics for future international cooperation on both technical and policy levels.

    Nya möjligheter att minska mängden deponerat gipsavfall från bygg- och ombyggnadsprojekt2018Report (Other academic)
    Abstract [en]

    Plasterboard is a common building material used in several parts of a building. In the case of retrofitting and demolition a part of the waste consists of components combined with the plasterboards, for example, frame work timber.

    In the case of new construction and retrofitting, construction waste is produced from clean plasterboard boards, either as cut off pieces or as unused whole boards. This waste can be used as raw material to produce new plasterboards. Manufacturers want to use gypsum from wasted boards to decrease the use of primary gypsum from mining and the quality requirements are relatively easy to achieve.

    In this project it has been found that the major construction companies already handle gypsum from new construction separately. This waste fraction could already be used in the production of new boards. Gypsum from retrofitting is usually assembled with other building materials and require more extensive efforts to achieve necessary purity to be used in the productions of new boards. Today, plasterboard waste is deposited or used to improve soil and/or sludge. In order to increase the recycling of plasterboards new inventory routines of rebuilding and demolition projects need to be elaborated. New tools and methods for dismantling plasterboard need to be development to achieve safe working environment and environmentally and economically sustainable recycling.

    Preparation plants producing raw material from plasterboard waste are already in operation. Today the waste mainly is wastage from the production stage. In order to increase the recycling of plasterboards from the construction- and demolition branch new logistic systems need to be developed, for example by creating collection points for gypsum board waste and / or developing new transport vehicles and systems. Prerequisites of changing the system of piece work in the construction industry need to be investigated with the intension to create a more sustainable building industry.

    Brandsäker energilagring - Sammanställning av risker och forskningsbehov2018Report (Other academic)
    Abstract [en]

    There is a large interest in the possibilities in storing produced energy that is not needed at that particular moment or to store energy when the cost for production of electricity is low. For this reason, different types of energy storage systems are used. With a fast development of new technologies and new forms of application for energy storage systems, it is important to also study the existing and potential risks with these types of systems.

    This prestudy describes the field, its risks and needs for research. It focuses on risks associated with fire, including explosions and when relevant the production of toxic gases. Although the main focus of the prestudy is different types of energy storage systems, the report contains information also on risks associated with storage of solid biofuels and waste. This means that the report contains information on risks and needs for research for batteries, hydrogen, biogas, liquified gases, biofuels and waste.

    Outnyttjat ensilage till förnybar energi2018Report (Other academic)
    Abstract [en]

    There are large amounts of unutilized silage from agriculture and from municipalities that harvest meadows and grasslands. This biomass is a disposal problem and a cost. At the same time, there are biogas plants which have an increased demand for substrates that do not compete with the production of feed and food. Unutilized silage can be an excellent biogas substrate provided it is effectively pretreated. This study is conducted as a case study of Jordberga Biogas plant in Skåne (in the south of Sweden), although the results of the project are applicable to other regions in Sweden where unutilized silage exists. The project aim was to study a 20 % replacement

    of today’s crop-based substrates in Jordberga biogas plant with unutilized silage from agriculture and municipalities. The project has been conducted by RISE Agrifood and Bioscience in collaboration with the German Biomass Research Center (Deutsches Biomasseforschungszentrum, DBFZ), Gasum, County Administrative Board of Skåne and Fogda Farm.

    The project was divided into three parts. In the first part the amounts of different types of unutilized silage was estimated, from arable land and forage areas at municipalities and County Administrative Boards, for the area around the Gasum Biogas plant in Jordberga, and for Sweden in total. In a second part the adequate technique for pretreatment was identified and tested in practical trials on different types of unutilized silage. In the third part cost calculations were done for the disintegration of the unutilized silage.

    The study showed that the largest potential for unutilized silage is from forage production. The area of meadows is much less with much lower yield. An assumption was made that 5% of the total amount of unutilized silage bales are available for biogas production. Project calculations showed that 35% of these must be used to substitute 20% of the crop based substrates at Jordberga. Depending on the quality and biogas yield, 12-23 ton DM is needed per day.

    Based on earlier studies and experiences from the project group, three machines were chosen for the practical tests to disintegrate silage bales; Rot Grind, RS CutMaster and I-GRIND. Roto Grind and I-GRIND used hammermill technique whereas RS CutMaster

    used knife rotors for disintegration. All three machines managed to disintegrate silage bales with DM-content varying from 40-70% DM. The particle length after disintegration was analyzed and a visual estimation of the effect on particle structure was made. Particle size after disintegration was the same for Roto Grind and RS CutMaster whereas it was considerable longer for I-GRIND. Disintegration worked better on silage with lower DM content regarding both particle size and structure for all tested machines.

    Based on the test results RS CutMaster had higher total disintegration costs compared with Roto Grind and I-GRIND. The differences in costs was mainly due to lower measured capacity of RS CutMaster, and higher depreciation and maintenance costs of both RS CutMaster and I-GRIND. To lower the costs to same level as Roto Grind and I-GRIND, RS CutMaster would need approximately 40% higher capacity than measured in the tests.

    Branschgemensam forskning för småskaliga biobränslepannor inför ekodesign2018Report (Other academic)
    Abstract [en]

    New domestic biofuel boilers must meet the Ecodesign Directive by 2020. In a market survey from 2014, none of 11 tested pellet boilers did meet all requirements, clearly indicating a developmental need. In the present project boiler manufacturers and research institutes have collaborated in response to the combustion engineering challenges.

    For pellet boilers, the biggest challenge with the Ecodesign Directive is that performance is largely calculated from partial load operation (low load). Previously, performance has only been determined at nominal load and the design has been optimized accordingly. In this project, tests have been run with two modern pellet boilers that have different types of pellet burner: one with horizontal burner tube and one with an underfeed burner cup. The results show that sufficient combustion performance could be maintained at partial load with both burner types. However, the tube burner exhibited significantly lower emissions at partial loads, probably due to the combustion zone in this burner being protected from heat radiation exchange with cooling boiler walls. A rather extensive work was laid down to provide the cup burner with a protective collar that would protect the combustion zone. However, it did not result in any significant improvement, probably because the supply of secondary air did not become optimal. A more extensive work is required to develop an optimal burner design of this type.

    For wood log boilers, it is a challenge to comply with the NOx requirements of the Ecodesign Directive of 200 mg / Nm³. A variety of temperature measurements in a wood log boiler resulted in the exclusion of thermal NOx formation. The boiler was fitted with a flue gas recirculation system, but it did not reduce the NOx emission. Then different varieties of wood fuels were tested. The NOx emission could be reduced to meet the requirement using barked birch wood. Chemical analyzes showed that the birch bark contained 0.49% nitrogen compared to 0.09% in the stock. Spruce logs also gave low NOx emissions, but that fuel resulted in increased CO and OGC emissions. For wood log boilers to meet the requirements for CO, OGC and dust, optimization is required under the wood's final combustion phase. At this stage, emissions are at its highest, due to the decreasing heat output while the airflow tends to cool down the flue gas faster than the combustible gases burn out. The optical particle measurement showed a clear correlation between dust and CO in the flue gas. If the boiler meets the CO limit, there are good chances that the requirement for particles also will be met.

    The efficiency specified in the Ecodesign Directive is calculated based on the fuel's higher heating value. In addition, some loss factors are subtracted. This implies that the boiler must not have unnecessarily large heat losses or excessive electricity consumption to meet the requirements. Measurements showed that the biggest loss occurs with the heat in the flue gas. The second largest loss is heat from the boiler body. For the efficiency, the importance of a well-insulated boiler body increases in the case of partial loads. The two pellet boilers used in the project were well suited to meet the eco-directive directive's efficiency requirements.

    Mechanical performance of polymer powder bed fused objects: FEM simulation and verification2018In: Additive manufacturing, ISSN 2214-8604, Vol. 24, p. 577-586Article in journal (Refereed)
    Abstract [en]

    Additive manufacturing (3D printing) enables the designing and producing of complex geometries in a layer-by-layer approach. The layered structure leads to anisotropic behaviour in the material. To accommodate anisotropic behaviour, geometrical optimization is needed so that the 3D printed object meets the pre-set strength and quality requirements. In this article a material description for polymer powder bed fused also or selective laser sintered (SLS) PA12 (Nylon-12), which is a common 3D printing plastic, was investigated, using the Finite Element Method (FEM). The Material Model parameters were obtained by matching them to the test results of multipurpose test specimens (dumb-bells or dog bones) and the model was then used to simulate/predict the mechanical performance of the SLS printed lower-leg prosthesis components, pylon and support. For verification purposes, two FEM designs for a support were SLS printed together with additional test specimens in order to validate the used Material Model. The SLS printed prosthesis pieces were tested according to ISO 10328 Standard. The FEM simulations, together with the Material Model, was found to give good estimations for the location of a failure and its load. It was also noted that there were significant variations among individual SLS printed test specimens, which impacted on the material parameters and the FEM simulations. Hence, to enable reliable FEM simulations for the designing of 3D printed products, better control of the SLS process with regards to porosity, pore morphology and pore distribution is needed.

    Technological development for sustainability: The role of network management in the innovation policy mix2018In: Technological forecasting & social change, ISSN 0040-1625, E-ISSN 1873-5509Article in journal (Refereed)
    Abstract [en]

    Despite the key role of actor networks in progressing new sustainable technologies, there is a shortage of conceptual knowledge on how policy can help strengthen collaborative practices in such networks. The objective of this paper is to analyze the roles of such policies – so-called network management – throughout the entire technological development processes. The analysis draws on the public management and sustainability transitions literatures, and discusses how various network characteristics could affect the development of sustainable technologies, including how different categories of network management strategies could be deployed to influence actor collaborations. The paper's main contribution is an analytical framework that addresses the changing roles of network management at the interface between various phases of the technological development process, illustrated with the empirical case of advanced biorefinery technology development in Sweden. Furthermore, the analysis also addresses some challenges that policy makers are likely to encounter when pursuing network management strategies, and identifies a number of negative consequences of ignoring such instruments in the innovation policy mix. The latter include inefficient actor role-taking, the emergence of small, ineffective and competing actor networks in similar technological fields, and a shortage of interpretative knowledge.

    Innovationskluster för internationalisering inom bioenergiområdet - förstudie2018Report (Other academic)
    Abstract [en]

    Bioenergy contributes to a sustainable energy mix in most countries worldwide, is the largest renewable energy generation and has a global development potential. Bioenergy today accounts for 60 percent of all renewable energy in the EU: 11 percent of all used energy, compared with 7 percent for all other renewable energy sources. However, the market for Swedish bioenergy and bioenergy technology in Sweden has decreased. Partly because our domestic market for new district heating installations has already been expanded and partly because the competition from electricity heating through energy efficient heat pumps in the residential segment takes over the exchange market. In order for Swedish know-how and products to grow, increased exports and visibility are important. An innovation cluster for internationalization in the bioenergy field cre-ates a meeting place that facilitates involved bioenergy companies and organizations to create sustainable growth inside and outside their own industry.

    Mälarporten, termiska lager i fjärrvärmesystemet2018Report (Other academic)
    Abstract [sv]

    I området Mälarporten har en storskalig förändring påbörjats. Området har tidigare bestått av gamla, till viss del nedlagda industrier, och kommer till stor del ersättas med bostäder, men också i viss mån kontor. Energi- och effektbehovet i området kommer att förändras mot tidigare vilket innebär att även fjärrvärmesystemet behöver förnyas. Vidare är det troligt att fjärrvärmenätet kommer arbeta med lägre temperaturer då nya fastigheter är av lågenergityp.

    Uppdraget i denna studie är att komplettera Mälarenergis arbete kring det kommande fjärrvärmenätet i området Mälarporten, Västerås med en kort utredning av termiska lager. Studien syftar till att öka kunskapen kring termiska lagers funktion i fjärrvärmenät inför ombyggnationen av fjärrvärmenätet i Mälarporten. Övergripande belyses teknik, viktiga parametrar och nuläget.

    Det finns flera tillämpningar på termiska lager i fjärrvärmesystem. Dels för att utjämna dygnsvariationerna i lasten i nätet, men också variationen över säsong. Vidare finns potential att använda ett termiskt lager i områden där det inte är möjligt med höga termiska effektuttag.

    De flesta installerade lagren idag är av typen sensibla lager men utvecklingen av latenta och termokemiska lager går fort. De latenta lagren är mer tillämpbara än de termokemiska som mestadels befinner sig på forskningsstadiet. Ett exempel på latent lager är snö vilket tillämpas idag i Sundsvall för fjärrkyla. En positiv bieffekt är att ett sådant lager kan underlätta rening av smältvattnet i en stad.

    Både KTH och Chalmers bedriver forskning för att utveckla latenta lagers tillämpningar i fjärrvärme/fjärrkylasystem. Det borde också vara intressant för Mälarenergi att titta närmare på SaltX installation i Berlin samt borrhålslagret i Linköping och befintliga groplager i Malung och Danmark.

    A Photocatalytic Membrane For Treatment of Pharmaceuticals in Wastewater2017Report (Other academic)
    Abstract [en]

    Toxic organics, pharmaceuticals and antibiotics are currently only partially or not at all removed from wastewater, as today’s wastewater treatment will only partly degrade those substances. Therefore, those substances will be found in the effluent from wastewater treatment plants and this can be a threat to both human health and aquatic species.

    Photocatalytic membranes show great promise as a method to combat the challenge of toxic organics in wastewater. The novel photocatalytic membrane developed in the project was shown to photocatalytically decompose organic compounds such as pharmaceutical residues and dyes in both tap water and treated effluent from a membrane bioreactor (MBR) wastewater treatment process. Several parameters affecting the affinity of the pharmaceuticals to the membrane surface, such as the hydrophobicity and pKa of the pharmaceuticals and the pH of the water, were shown to affect the efficacy of the removal.

    Finally, when irradiated with UV light the photocatalytic membrane showed promise of keeping high flux and reducing downtime by lengthening the cleaning cycle.

    Samarbeten för förbättrad trafikinformation: En pilotstudie av samarbetsmöjligheter inom Waze Connected Citizens Program2018Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    Denna rapport undersöker explorativt möjligheter, konsekvenser och utmaningar relaterade till fördjupade datasamarbeten mellan offentliga aktörer och privata tjänsteföretag. I projektet undersöks specifikt samarbetsprogrammet Waze CCP och på vilket sätt ett fördjupat samarbete med Waze skulle kunna tillföra nyttor för främst Trafikverket. 

    Rapporten beskriver både innehållet i tjänsten Waze och hur samarbetet mellan Waze och offentliga aktörer ser ut på olika platser i världen. Förutsättningar och konsekvenser för olika tillämpningsområden har studerats närmare ur en svensk kontext och lett fram till ett antal användningsfall där en stor nytta med ett fördjupat samarbete identifierats. 

    Datasamarbeten mellan offentliga aktörer och privata (ofta globala) tjänsteföretag utmanar traditionella arbetssätt och kräver nya former av relationer. Samtidigt innebär framväxten av digitala ekosystem, digitalisering och tillgången till helt nya typer av data stora möjligheter till utveckling av den offentliga verksamheten. 

    De användningsfall som särskilt lyfts fram i rapporten och där fortsatt arbete rekommenderas är:

    • Snabb och heltäckande överblick för trafikledare
    • Sömlös navigering i tunnlar utan GPS-täckning
    • Riktad trafikinformation genom analys av resmönster
    • Förbättrad trafikinformation genom Waze-appen
