    • Comparative life cycle assessment of tailings management and energy scenarios for a copper ore mine: A case study in Northern Norway 

      Song, Xingqiang; Pettersen, Johan Berg; Pedersen, Kristine Bondo; Røberg, Stian (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-05)
      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 industry is still in progress. This paper carried ...

    • Life cycle assessment of recirculating aquaculture systems: A case of Atlantic salmon farming in China 

      Song, Xingqiang; Liu, Ying; Pettersen, Johan Berg; Brandão, Miguel; Ma, Xiaona; Røberg, Stian; Frostell, Björn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-01)
      Recirculating aquaculture systems (RAS) are 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 environmental measures. So far, the application of life cycle ...

    • Life cycle impact assessment in the arctic: Challenges and research needs 

      Pettersen, Johan Berg; Song, Xingqiang (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-08)
      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 spatial differentiation in characterization modeling, and ...
