Bunkerservice ur en hamns konkurrensperspektiv - En fallstudie i Göteborgs närområde

For a port to be able to compete it needs to offer more than a berth. Bunkering is such a service. Bunkers are a major cost for shipping companies, because of this the selection of bunkering port is an important decision. The availability of bunker on the global market is abundant and the competitiveness between ports and suppliers are fierce. The purpose of this report is to determine the underlying factors of a shipping company’s choice of bunkering port, as well as to present suggestions on how the Port of Gothenburg can develop their competitiveness in bunkering services. This study focuses on two questions: How is the competitiveness among bunkering ports surrounding the Gothenburg region? How can the port of Gothenburg work to develop a competitive bunker port? The report is based on a case study with interviews with several stakeholders within the bunker market in the Gothenburg region. The case study is based on earlier research about the competitiveness on the bunker market as well as port selection criteria. Statistic data for the Gothenburg region trade has also been collected. The authors find that the port of Gothenburg is a competitive port, additionally the port possesses good possibilities to increase its competitiveness as a bunker port, mainly because of its geographical position and the closeness to refineries. The port is however lacking some bunkering services infrastructure to actually compete with the largest bunkering ports in the world. The most important competitive factor is the price of bunker, in which the port of Gothenburg is not in a leading position, although there is a good availability and quality in the bunkering services offered in the port. The authors find that an increase of internal competition would raise the total competitiveness as a bunker port

Closing nutrient loops through decentralized anaerobic digestion of organic residues in agricultural regions: A multi-dimensional sustainability assessment

Decentralized anaerobic digestion (AD) of manure and organic residues is a possible strategy to improve carbon and nutrient cycling within agricultural regions, meanwhile generating renewable energy. To date, there has been limited adoption of decentralized AD technology in industrialized countries owing to low profitability for plant operators. There remains a need to demonstrate the wider sustainability of small-scale, decentralized AD in order to justify policy support for such a strategy. This study applies a multi-dimensional assessment of the environmental, economic and social sustainability of two scenarios of decentralized, farm-scale AD of pig slurry and organic residues in Southern Sweden. The environmental dimension was assessed by means of an expanded boundary life cycle assessment, in which trade-offs between fertilizer replacement, soil organic carbon accumulation, digestate/manure storage and application, transport and soil emissions were evaluated. The economic dimension was assessed through modelling of the net present value and internal rate of return. Finally, the social dimension was assessed by means of a stakeholder perception inquiry among key stakeholders in the field. It was concluded that the overall environmental balance of decentralized AD was favorable, while also the net present value could be positive. Fertilizer replacement, soil organic carbon and digestate storage effects were identified as important factors that should be accounted for in future life cycle assessments. A key issue for interviewed stakeholders was product quality assurance. Wider application of multi-dimensional sustainability assessment, capturing important nutrient cycling effects, could provide an evidence base for policy to support sustainable deployment of decentralized AD

Renewal of forest based manufacturing towards a sustainable circular bioeconomy

Environmental problems, combined with European Union environmental and energy policies shaped to address them, have created pressures for change. Some of these open significant opportunities to renew industries. This report delivers new understanding of the potential of circular economy for sustainable renewal of manufacturing in bio-based industries. With particular focus on novel value chains, it provides novel insights into the role of innovation policies in facilitating the shift towards sustainable, circular bioeconomy in Finland and Sweden. The textile and multi-storey wood construction sectors, and emergent biorefineries are utilised as case studies that deepen understanding of the circular bioeconomy, its opportunities, barriers, and impacts, and the policies that affect its emergence. Recent developments of bioeconomy and circular economy solutions and governance in the Netherlands are also summarised in order to deliver contrasting context to the Nordic focus countries. In this work, the bioeconomy is conceptualised as an economy where the basic building blocks for materials, chemicals and energy are derived from renewable biological resources, such as plant and animal biomass. The essence of the circular economy, that is used here, lies in maximisation of added value and in making the best use of any extracted raw material. This analysis shows that to date discussions and activities related to the promotion of bioeconomy and circular economy have largely been separate efforts, but there are signs that the discussions may converge. It finds that while the form of developments are similar in Finland and in Sweden in the case areas (i.e. textiles, wood construction and biorefineries), there are also clear differences in the strengths of the countries. Evidence is found that such strengths offer potential to develop world leadership in a circular bioeconomy. The report identifies policy recommendations to support renewal of manufacturing in the wood based industries towards a sustainable circular bioeconomy
