Dublet Adli, Gabrielle; Cornelissen, Gerard; Eek, Espen; Sørmo, Erlend; Hansen, Caroline Berge; Tjønneland, Maren Valestrand; Maurice, Christian (Peer reviewed; Journal article, 2023) -
Analysis, occurrence and removal efficiencies of organophosphate flame retardants (OPFRs) in sludge undergoing anaerobic digestion followed by diverse thermal treatments
Varela, Gabriela Castro; Sørmo, Erlend; Yu, Guanhua; Sait, Shannen Thora Lea; Villa Gonzalez, Susana; Arp, Hans Peter Heinrich; Asimakopoulos, Alexandros (Peer reviewed; Journal article, 2023) -
Biochar for the Improvement of Soil and Rock With Acid Potentia
Sørmo, Erlend; Kämäräinen, Erika; Edvardsson, Matilda; Maurice, Christian (Peer reviewed; Journal article, 2020)Biochar is a carbonaceous material generated by the heating of organic matter under limited access to oxygen (called pyrolysis). While pyrolysis is applied to dry feed, hydrothermal carbonization can be used for wet materials ... -
Distribution of PAHs, PCBs, and PCDD/Fs in products from full-scale relevant pyrolysis of diverse contaminated organic waste
Sørmo, Erlend; Krahn, Katinka Muri; Flatabø, Gudny Øyre; Hartnik, Thomas; Arp, Hans Peter Heinrich; Cornelissen, Gerard (Peer reviewed; Journal article, 2023)Biomass pyrolysis is the anoxic thermal conversion of biomass into a carbon rich, porous solid, often called biochar. This could be a better waste management alternative for contaminated organic wastes than incineration, ... -
Eco-toxicological and climate change effects of sludge thermal treatments: Pathways towards zero pollution and negative emissions
Morales Arancibia, Marjorie Alejandra; Arp, Hans Peter Heinrich; Varela, Gabriela Castro; Asimakopoulos, Alexandros; Sørmo, Erlend; Peters, Gregory; Cherubini, Francesco (Peer reviewed; Journal article, 2024) -
Flame curtain kilns produce biochar from dry biomass with minimal methane emissions
Cornelissen, Gerard; Sørmo, Erlend; de la Rosa, Ruy Korscha Anaya; Ladd, Brenton (Peer reviewed; Journal article, 2023) -
Formation and availability of methylmercury in mercury-contaminated sediment: effects of activated carbon and biochar amendments
Sørmo, Erlend; Silvani, Ludovica; Braaten, Hans Fredrik Veiteberg; Bryntesen, Tina; Eek, Espen; Cornelissen, Gerard (Peer reviewed; Journal article, 2022)Purpose As the formation of toxic and bioaccumulative methylmercury (MeHg) in Hg-contaminated sediments is of great concern worldwide, suitable remediation options are needed. Activated carbon (AC) amendment is a contested ... -
Industrial byproducts for the soil stabilization of trace elements and per- and polyfluorinated alkyl substances (PFASs)
Zhang, Yaxin; Cornelissen, Gerard; Silvani, Ludovica; Zivanovic, Valentina; Smebye, Andreas; Sørmo, Erlend; Thune, Gorm; Okkenhaug, Gudny (Peer reviewed; Journal article, 2022) -
Industrially relevant pyrolysis of diverse contaminated organic wastes: Gas compositions and emissions to air
Flatabø, Gudny Øyre; Cornelissen, Gerard; Carlsson, Per; Nilsen, Pål Jahre; Tapasvi, Dhruv; Bergland, Wenche Hennie; Sørmo, Erlend (Peer reviewed; Journal article, 2023) -
Sewage sludge biochars as effective PFAS-sorbents
Krahn, Kathinka M.; Cornelissen, Gerard; Castro, Gabriela; Arp, Hans Peter; Asimakopoulos, Alexandros; Wolf, Raoul; Holmstad, Rune; Zimmerman, Andrew R.; Sørmo, Erlend (Peer reviewed; Journal article, 2022) -
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 ... -
Stabilization of PFAS-contaminated soil with sewage sludge- and wood-based biochar sorbents
Sørmo, Erlend; Lade, Clara Benedikte Mader; Zhang, Junjie; Asimakopoulos, Alexandros; Åsli, Geir Wold; Hubert, Michel; Goranov, Aleksandar I.; Arp, Hans Peter Heinrich; Cornelissen, Gerard (Peer reviewed; Journal article, 2024) -

Waste timber pyrolysis in a medium-scale unit: Emission budgets and biochar quality
Sørmo, Erlend; Silvani, Ludovica; Thune, Gorm; Gerber, Helmut; Schmidt, Hans-Peter; Cornelissen, Gerard (Peer reviewed; Journal article, 2020)Pyrolysis of organic waste or woody materials yields a stable carbonaceous product that can be mixed into soil and is often termed “biochar”. During pyrolysis carbon-containing gases are emitted, mainly volatile organic ...
