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)Organophosphate flame retardants (OPFRs) are a complex group of contaminants to deal with in sewage sludge, as currently there is a lack of robust analytical methods to measure them and management strategies to remove them. ... -
The decomposition and emission factors of a wide range of PFAS in diverse, contaminated organic waste fractions undergoing dry pyrolysis
Sørmo, Erlend; Varela, Gabriela Castro; Hubert, Michel; Licul-Kucera, Viktória; Quintanilla, Marjorie; Asimakopoulos, Alexandros; Cornelissen, Gerard; Arp, Hans Peter Heinrich (Peer reviewed; Journal article, 2023)Current treatment options for organic waste contaminated with per- and polyfluoroalkyl substances (PFAS) are generally limited to incineration, composting or landfilling, all resulting in emissions. Dry pyrolysis is a ... -
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)The high moisture content and the potential presence of hazardous organic compounds (HOCs) and metals (HMs) in sewage sludge (SS) pose technical and regulatory challenges for its circular economy valorisation. Thermal ... -
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)The use of sewage sludge to produce biochar-based sorbents for per- and polyfluoroalkyl substances (PFAS) removal from water and soil may be an economically and environmentally sustainable waste management option. This ... -
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 (Journal article; Peer reviewed, 2024)
