Hållbarhet inom stålindustrin : Innovationer och strategier för en grönare framtid

Wickberg, William, Holfve, Tobias January 2023 (has links)
The steel industry is in a critical situation where the industry contributes to global warming through its emissions, resulting from the burning of fossil fuels. There are higher demands from various stakeholders and laws and regulations are becoming increasingly strict. The steel industry has been forced to change its processes and production in whole or in part to meet these demands. The production of steel must become more sustainable and therefore innovative solutions are required to promote sustainable steel production. The purpose of this study is to investigate how possible requirements for sustainability have affected the innovative work in the Swedish steel industry. The survey is based on the work of two Swedish steel companies. These are being compared regarding innovation and sustainability strategies to see if there are similarities and/or differences in their work. The purpose of the study is fulfilled through literature studies and interviews with two case companies in the Swedish steel industry. The collected empirical data in the study shows that both companies work actively with their innovation and sustainability work. Both companies have a vision to reduce their use of fossil sources and instead move towards a more fossil-free steel production. The case companies also have a strong focus on circularity and the use of scrap. What differentiates the two companies is their production techniques where they have applied different innovation strategies. Even their sustainability requirements differ in some ways due to the size of the company. Research on the connection between stakeholders' sustainability requirements and the innovation work in the Swedish steel industry was something that was missing. The study has therefore identified the research gap and tried to contribute information to this area. The study has contributed information about which stakeholders' sustainability requirements promote innovative solutions with the aim of reducing the steel industry's emissions. Further research can study whether the stakeholders can set higher demands and see what change this would have led to.

Nyckelfaktorer för Grön Innovation inom Bygg- och Anläggningssektorn / Key Factors for Green Innovation in Infrastructure Development

Kourinnoi, Bogdan January 2020 (has links)
Bygg- och anläggningssektorn är ansvarig för en betydande del av Sveriges totala koldioxidutsläpp och står inför stora utmaningar när den nu skall försöka minska dess klimatpåverkan. Bygg- och anläggningssektorn behöver under det kommande decenniet hitta lösningar och arbetssätt som halverar sektorns totala koldioxidutsläpp. Entreprenörer kommer att behöva hitta sätt att effektivt genomföra både befintliga lösningar och sådana som inte ännu inte finns tillgängliga. Det här examensarbetet har undersökt vilka nyckelfaktorer som finns för ett lyckat genomförande av nya lösningar med låg klimatpåverkan vid väg- och anläggningsprojekt. Som en fallstudie undersöktes implementeringen av Multicem vid två av Skanskas projekt. Multicem är ett klimatmässigt fördelaktigt alternativ till produkten kalkcement och används vid genomförande av inblandningspelare i jordförstärkningssyfte. Fallstudien tillsammans med litteratur och intervjuer bidrog till slutsatser om vad som måste till för att projekt skall kunna genomföra klimateffektiviseringsåtgärder. Det som har observerats är att projekts möjlighet att klimateffektivisera beror på projekt-, organisations- och sektorspecifika faktorer och tydligt försvåras av bygg- och anläggningssektorns projektstruktur. Studien visar att nyckelfaktorer på projektnivå är att lösningar introduceras tidigt, är ekonomiskt fördelaktiga och kan implementeras enkelt med hjälp av standardiserade arbetssätt. Dessutom måste tidigare erfarenheter spridas effektivt inom organisationen, så att erfarenheter från projekt blir tillgängliga för nya projekt. Organisatoriska nyckelfaktorer för lyckad klimateffektivisering är engagerad ledning på alla nivåer och samverkan mellan olika aktörer och olika projekt. Examensarbetet visar även att bygg- och anläggningssektorn är beroende av att ett övergripande arbete för klimateffektivisering sker inom sektorn. Entreprenörer är beroende av att grönt innovationsarbete pågår i hela leverantörskedjan för att möjliggöra nya fördelaktiga arbetssätt. Dessutom är Trafikverkets roll vid upphandlingsskeden och kravställning ytterst viktig eftersom myndigheten styr arbetet som entreprenörer och andra aktörer kan utföra. / The construction industry accounts for a major part of Sweden’s overall carbon dioxide emissions, and is because of that, today facing significant challenges in its aim to mitigate the industry’s total climate impact. During the coming decade, the Swedish infrastructure construction industry must find solutions that can mitigate its carbon dioxide emissions by 50 per cent. This means that contractors will have to find ways to efficiently implement both existing and innovative solutions. This master’s thesis has researched which key factors apply for successful implementation of green solutions at infrastructure development. As a case study, the implementation of the product Multicem at two of Skanska’s developments was researched. Multicem is a product that can be used in dry deep mixing in order to limit carbon emissions. The case study, together with literature and interviews, provided conclusions on which factors are relevant for successful implementation of solutions that result in less carbon dioxide emissions. The research shows that a project’s capacity to mitigate its emissions is decided by projectspecific, organisational and sectorial factors, and is limited by the construction industry’s project-based characteristics. The study shows that key aspects on a project-level are that the solutions ought to be introduced during an early phase, be economically beneficial and also be implemented easily through standardised working routines. Additionally, earlier experiences must be spread efficiently within the organization so that internal knowledge can be accessible for new developments. Organisational key factors for successful green innovation are: engaged managerial personnel and cooperation between different companies and developments. The results from this master’s thesis show that the construction industry is dependent on that climate change mitigation efforts are taken within the whole industry. In order to develop beneficial solutions and methods, contractors are reliant on that the entire supply chain work towards green innovation. Additionally, the Swedish Transport Administration’s role when designing contracts and legislation is of the outmost importance, since it as an authority regulates the work contractors and consultants perform.
