    Development of dynamic grouting under laboratory and field conditions2022In: Geomechanics and Tunneling, ISSN 1865-7362, E-ISSN 1865-7389, Vol. 15, no 5, p. 535-539Article in journal (Refereed)
    Abstract [en]

    When it comes to underground structures, water ingress from the surrounding formations leads to several environmental, economic and sustainability issues. To obtain the sealing, the grouting of rock fractures is done. Today, in the grouting operations, which are commonly conducted in almost all the tunnel and subsurface infrastructure projects, the pressure applied is static. This type of applied pressure might be suitable for the large fracture apertures > 100 μm, but it has been acknowledged that it is difficult to obtain sufficient penetration through smaller apertures, where filtration of cement particles starts to occur. Research is already done to overcome this issue by applying dynamic grouting pressure instead of static. It was proved that this approach erodes the formed filter cakes and improves grout penetrability in fractures below 100 μm. This research focuses on low-frequency rectangular pressure impulse as an alternative to other methods. The goal is to improve grout spread in micro-fractures (especially in apertures < 70 μm). During the investigation, a prototype dynamic injection equipment was built and tested under laboratory conditions. The 4 m variable aperture long slot (VALS) was used in the experiments to simulate rock fractures. The test showed better grout penetrability using dynamic pressure approach. At the current time of writing this article, preparation works are done for field test of prototype equipment at SKB Hard Rock Laboratory (HRL) at Äspö, Sweden.

    Policies as drivers for circular economy in the construction sector in the nordics2021In: Sustainability, E-ISSN 2071-1050, Vol. 13, no 16, article id 9350Article in journal (Refereed)
    Abstract [en]

    A circular economy (CE) represents the key alternative to the linear ‘take-make-consume-dispose’ economic model, that still predominates in the construction sector. This study investigates how policies support CE-focused businesses in the construction sector in the Nordics. A literature review, the creation of a database, a review of Nordic actors with a CE focus, and targeted interviews with actors across the value chain of the construction sector in Denmark, Finland, Norway, and Sweden enabled us to benchmark the CE policy landscape and assess how CE policies at different levels support CE business models in the construction sector. The results show that the construction sector is well represented in the CE policy frameworks and that many business opportunities are created when national and local policies are put into practice. The implementation of policies is mainly done via three key concepts, i.e., planning, requirements for sustainable constructions, and requirements for public procurement. It can be concluded that policies are drivers for the implementation of a CE and support CE business models in the Nordics. © 2021 by the authors.

    Aerosol-based deposition of broadband antireflective silica coating with closed mesoporous structure2023In: Solar Energy Materials and Solar Cells, ISSN 0927-0248, E-ISSN 1879-3398, Vol. 250, p. 112078-112078, article id 112078Article in journal (Refereed)
    Abstract [en]

    Solar energy will be a crucial part of the sustainable, fossil free energy production of the future. A majority of this will be produced by solar collectors and photovoltaics. Important for the efficient utilization of the incident solar energy for both technologies are a cover glass with antireflective coatings giving it a high solar transmittance. In the current paper we describe the development of antireflective mesoporous silica coatings on low-iron float glass using the aerosol-based nFOG™ deposition technique. The coatings exhibit a hexagonal and closed pore structure, high smoothness, superhydrophilic properties (contact angle <5°) and consistent thicknesses of approximately 110 nm. This is in line with optimal thickness determined from simulations of the antireflective behavior. Low-iron float glass coated on both sides show a highly reproducible solar weighted transmittance of 95% in the wavelength range 300–2500 nm and an antireflective effect increasing with incident angle. The smoothness, closed pores and low contact angle indicate a high cleanability, which in combination with the high transmittance render a competitive broadband antireflective coating well adapted for solar glass applications.

    Strategies to mitigate the effects of future extreme heat waves - A new method for mapping2020In: IOP Conference Series: Earth and Environmental Science, IOP Publishing Ltd , 2020, Vol. 588, no 3, p. 1.06-1.10Conference paper (Refereed)
    Abstract [en]

    Global warming is increasingly causing extreme weather events, such as heat waves. One-way heat waves are problematic in society, particularly in urban areas, is because of their negative impact on vulnerable groups including elderly people and children. Organizations such as municipalities that are responsible for local schools, day care centres and/or elderly homes, may struggle to provide the necessary care and function during extreme heat waves. This work explores how remote sensing images providing historical data of land surface temperatures (LST) can be used to create summer urban heat island maps and heat wave intensity, and in the longer run, how such information could be used by municipalities and other actors to mitigate effects of future heat waves. The method presented in this study was used to detect the “hot spots” in two participating Swedish municipalities and identify the municipal services located within these spots based on MODIS (1 km) and Landsat (30 m) LST datasets. Furthermore, this study showed that urban heat island phenomenon existed in the two participating municipalities. In general, this methodology can be applicable at both local and regional scale, although it might require additional site-specific data. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

    Changing the Dynamics and Impact of Innovation Management: A Systems Approach and the ISO Standard2022Book (Other academic)
    Abstract [en]

    The ISO Innovation Management System (IMS) Standard (ISO 56002) provides a much needed and well-timed input to the innovation management discipline. While research efforts within the domain of innovation management have vastly increased over the past decades, research has primarily been conducted through specific contributions to distinct areas of innovation management (e.g., top management, culture, processes), lacking a more holistic perspective. Practitioners know that managing innovation is challenging. Bringing in a globally recognised standard that offers a holistic perspective will be key in professionalising the innovation management discipline, much like quality management and project management standards have done in the past. This book focuses on the ISO Innovation Management System Standard and the links with ISPIM's Body of Knowledge (BoK) special interest group, the ISO innovation management community, and the International Collaboration Platform for Innovation Management System (ICP4IMS). It covers four topics as follows: • Introduction to a systems approach for innovation management and the ISO Innovation Management System Standard (ISO 56002), including historical context, descriptions of terms, typology, and the clauses in the Standard. • Elaboration of the innovation management fundamentals and principles (ISO 56000). • Features 16 case studies of diverse organisations from around the globe, including those that have implemented a management system before the Standard was released and those following it now, completely or partially. • Lessons learned and implications, including insights for how to take innovation management to its next level to address opportunities and challenges in organisations and societies.

    Future Adaptive Design – How to create longer-lasting products for circular offerings2023Report (Other academic)
    Abstract [en]

    Longer product life – a threat to business, or a way towards long-term profitability and reduced environmental load? The vision of a circular economy proposes that companies can become more profitable and sustainable by adopting so-called circular practices. This aspiration has inspired many manufacturing companies to start their transition journey from a traditional linear to a more circular business by exploring how to close material flows, improve eco-efficiency, and utilise renewable energy. The opportunity to extend product lifetimes, however, remains underexplored although it has potential to contribute significant environmental benefits. Some may see longer product life as a threat to business since it may negatively affect sales of new products and profitability for companies dependent on linear business logic, especially for those that produce and sell products in large volumes. The idea of extended product lifetimes challenges traditional logics of designing for a reasonable lifetime or planned obsolescence. In this guide, we argue that longer product life can be a pathway towards long-term profitability and value capture within the limits of the planet. Emerging global trends also favor longer-lasting products. Upcoming legislation will put more pressure on manufacturers to enable repair, offer spare parts, and provide information about expected product life. More frequent material and component shortages as well as price volatility will make excessive material use less profitable. Rising global consumer awareness will also pressure companies to deliver longer-lasting products. In this guide, we present practical ways to design products for extended lifetimes that are suitable for circular business models, which have the potential to preserve and capture embedded values over time. We believe that companies that design, manufacture, or offer durable goods are the ones that can benefit the most from finding ways to extend product lifetimes. Companies that develop and offer fast-moving consumer goods or consumables can nevertheless also benefit from considering opportunities to increase longevity. This guide is for change agents who have already started or who want to take on the challenge of designing longer-lasting products and implementing circular business models. This includes designers and engineers, business and design managers, and those in top management that create enabling conditions so that products can be designed for longer lifetimes.
