    • Stabilization of PFAS-contaminated soil with activated biochar 

      Sørmo, Erlend; Silvani, Ludovica; Bjerkli, Nora; Hagemann, Nikolas; Zimmermann, Andrew R.; Hale, Sarah; Hansen, Caroline Berge; Hartnik, Thomas; Cornelissen, Gerard (Peer reviewed; Journal article, 2020)
      Biochars are considered potential sustainable sorbents to reduce the leaching of per- and polyfluoroalkyl substances (PFAS) fromcontaminated soils. However, biochar characteristicsmust probably be optimized to achieve ...
    • Utfordringer med svarte leirskifere; mellomlagring og naturlige blandmasser 

      Wærsted, Frøydis Meen; Fjermestad, Halldis; Totland, Christian; Børresen, Marion; Slinde, Gøril Aasen; Hansen, Caroline Berge; Tønnessen, Elisabeth; Hagelia, Per; Erstad, Lars; Baardvik, Gunvor (Chapter, 2022)
      Det er planlagt flere store byggeprosjekt i Oslo-regionen de neste årene. Dette vil resultere i utgraving av potensielt syredannende svart leirskifer i volumer som er større enn kapasiteten til godkjente deponier. NGI har ...
