Renewable reductants are intended to significantly reduce CO2 emissions from ferro-alloy production, e.g., by up to 80% in 2050 in Norway. However, charcoals provide inferior properties compared to fossil fuel-based reductants, which can hamper large replacement ratios. Therefore, conditioning routes from coal beneficiation was investigated to impr...

European Aluminium organised an online Cross-fertilisation workshop "Towards a more sustainable alumina production in Europe", in partnership with RemovAL and ReActiv, on the 23rd and the 24th of September 2021. In this presentation we show some of the results from the LCA work done in the RemovAl project, comparing use of BR as iron source, or as...
Article
Recirculating aquaculture systems (RAS) is an alternative technology to tackle the major environmental challenges associated with conventional cage culture systems. In order to systematically assess the environmental performance of RAS farming, it is important to take the whole life cycle into account so as to avoid ad-hoc and suboptimal environmen...

Article
Full-text available
Life cycle assessment (LCA) is increasingly used for environmental assessment of products and production processes to support environmental decision-making both worldwide and in the Arctic. However, there are several weaknesses in the impact assessment methodology in LCA, e.g., related to uncertainties of impact assessment results, absence of spati...
Article
In support of continuous environmental improvement in the mining industry, it is important to systematically assess the environmental impacts of mining and mineral processing operations from a life cycle perspective. Although life cycle assessment (LCA) is widely used as an environmental systems analysis tool, the application of LCA in the mining i...
Conference Paper
Full-text available
Life cycle assessment (LCA) is increasingly used to support European environmental policy and governance, e.g. on integrated pollution prevention, ecodesign directives, environmental management systems, green procurement and environmental product labelling. However, there are several known weaknesses in using LCA as an environmental decision suppor...
Article
The aluminium scrap market is undergoing rapid changes which will trigger off new recycling strategies. As the cast scrap market saturates it will become economically feasible to apply scrap also in aluminium wrought alloy production. As part of an EU project, Sustainable and efficient Production of Light weight solutions (SuPLight) a method for as...
Conference Paper
In this study we present a life cycle assessment model for a subset of EOR techniques applied to a field on the Norwegian Continental Shelf, focusing on a few select techniques, including polymer injection. The purpose is to document the impact of enhanced oil production on the emissions- intensity of the added barrels, for example kgCO2e/bbl. Proc...
Article

The general focus in environmental evaluation of offshore drilling is the discharge of cuttings and chemicals to local marine environment, in some cases including emissions to air from offshore turbines and engines. However, significant impacts occur as a result of processes upstream and downstream from drilling operations, in the manufacture of ch...
Article
Background, Aim, and ScopeThe identification and assessment of environmental tradeoffs is a strongpoint of life cycle assessment (LCA). A tradeoff made in many product systems is the exchange of potential for occupational accidents with the additional use of energy and materials. Net benefits of safety measures with respect to human health are best...
Article
Life-cycle assessment (LCA) is the method of inventorying, assessing, and interpreting environmental interventions caused by products and product systems through their life cycle. The ecotoxicity of metals has proven a challenge for LCA given metal characteristics such as reversibility of removal processes, speciation, and the effect on bioavailabi...
Thesis
The full thesis is available for download (open): http://hdl.handle.net/11250/233345 The goal of this thesis is to provide the means for discussion of overall benefits of alternative offshore drilling technologies. Life-cycle assessment is used to assess environmental impact of alternative drilling technologies. Life-cycle assessment is well-suit...
Article
This paper presents an integrated management technique that has been employed with success over the last 8 years in Statoil operations offshore Norway. The technique has been applied in integrated management of drilling fluids and drilling waste and is particularly suited for this purpose. It is argued that the attractive feature of the technique;...
Article
Characterization factors for ecotoxicity in life cycle impact assessment are traditionally calculated as the product of effect and fate factors. Steady-state multiple compartment models are used to calculate the fate factor, while effect factors are derived from species sensitivity distributions (SSDs) for multiple substances using average or margi...
Article
Full-text available
Fate modeling for characterization of ecotoxic substances in life-cycle impact assessment (LCIA) is traditionally performed with steady-state multi-compartment models. Instantaneous mixing within compartments is an implicit assumption of the multi-compartment model. Others have shown that steady-state models can account for pulse-exposure if the ec...
