With<br>global population growth, the generation of such waste is expected to rise, necessitating<br>responsible management strategies. Therefore, the valorisation potential through hydrothermal<br>carbonization (HTC) was investigated. HTC on eight fish and crustacean species was performed<br>at three different temperatures (T = 200, 220, 240°C, t = 5h, w/b = 7). The produced hydrochars<br>(HC) were characterized through point zero charge (PZC), elemental and proximate analysis and<br>FTIR. Their adsorption characteristics were evaluated using kinetic and adsorption models and<br>using one-point adsorption experiments with an anionic (methyl orange, MO) and cationic<br>(methylene blue, MB) dye. In addition, the influence of ionic strength on the adsorption<br>performance was evaluated. Crustacean-HC showed higher yields (37-69%) than fish-HC (15-<br>22%). Furthermore, crustacean-HC showed higher PZC than fish-HC (7.93 versus 6.49). The<br>adsorption capacity of the HCs (MB: 2.7-10.8 mg/g and MO: 5.9-9.2 mg/g) showed a higher<br>adsorption of MO for the crustacean-HCs. Difference in ionic strength in adsorption experiments<br>was concluded to not yield significantly different adsorption results. The difference in yields, PZC<br>and adsorption results were explained by the differences in feedstock composition, further<br>emphasizing the importance of elucidating the inherent feedstock characteristics for waste<br>utilization","AbstractOtherLang":"Deze masterthesis behandelt het groeiende probleem van marien bioafval dat wordt gegenereerd<br>door de consumptie van vis en schaaldieren, wat aanzienlijke milieu en socio-economische<br>uitdagingen met zich meebrengt. Met de groei van de wereldbevolking wordt verwacht dat de<br>productie van dergelijk afval zal toenemen, waardoor verantwoorde beheerstrategieën nodig zijn.<br>Daarom werd het valorisatiepotentieel via hydrothermale carbonisatie (HTC) onderzocht. HTC<br>werd op acht vis- en schaaldiersoorten uitgevoerd bij drie verschillende temperaturen (T = 200,<br>220, 240°C, t = 5u, w/b = 7). De geproduceerde hydrochars (HC) werden gekarakteriseerd door<br>middel van point zero charge (PZC), elementaire en proximate analyse en FTIR. Hun<br>adsorptiekarakteristieken werden geëvalueerd met behulp van kinetische en adsorptiemodellen<br>en via éénpuntsadsorptie-experimenten met een anionische (methyloranje, MO) en kationische<br>(methyleenblauw, MB) kleurstof. Daarnaast werd de invloed van de ionsterkte op de<br>adsorptiecapaciteiten geëvalueerd. HC van schaaldieren vertoonde een hoger rendement (37-<br>69%) dan HC van vissen (15-22%). Bovendien vertoonde HC van schaaldieren een hogere PZC<br>dan HC van vissen (7,93 versus 6,49). De adsorptiecapaciteit van de HCs (MB: 2,7-10,8 mg/g en<br>MO: 5,9-9,2 mg/g) toonde een hogere adsorptiecapaciteit van MO voor de schaaldieren. De<br>invloed van de ionsterkte in de adsorptie-experimenten werd aangetoond niet significant te zijn.<br>Het verschil in opbrengst, PZC en adsorptieresultaten werd verklaard door de verschillen in de<br>samenstelling van de soort vis en schaaldier, wat benadrukt hoe belangrijk het is om de inherente<br>eigenschappen van de grondstof voor het gebruik van afval te achterhalen.","BibLvlCode":"M","StandardTitle":"Valorization of South Korean marine biowaste via hydrothermal carbonization: hydrochar synthesis and investigation of adsorption capacity","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"marine biowaste, biorefinery","OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2024,"DateUpdate":"2025-01-06","DateCreate":"2025-01-06","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":405164,"ISBN":null,"PubliDate":2024,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"89","Place":"Gent","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":"MSc","ThesisID":405164,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":89},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Kooy","Firstname":"Elisa","Initials":"E.","Affiliation":"Ghent University","Discriminator":null,"CorporateFlag":0,"BEntID":402959,"AutID":579170,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":"EnVOC","InsFSN":"Universiteit Gent; Faculteit Bio-ingenieurswetenschappen; Vakgroep Groene Chemie en Technologie; Onderzoeksgroep Organische Milieuchemie en -Technologie","ORCID":null,"PersID":null,"InsID":106}],"mapdetails":null,"datasets":null,"monographs":null,"monparts":null,"serparts":null,"BEntOpen":null,"BEntPrivate":null,"availability":[{"BInstID":411073,"LibID":36,"BRefID":405164,"EmbargoDate":null,"FullEmbargoDate":null,"PhysMedID":16,"hasOCRd":1,"ShelfLocCode":"411073","RFID":null,"PaidValue":null,"Medium":"Server","Description":"VLIZ Open Access","Acronym":"VLIZ","Library":"Vlaams Instituut voor de Zee","DutchTerm":"Open access","URL":null,"ClassifID":53,"Classification":"Open access","ReqLink":null,"ClassifTypID":1,"URLLocation":"https://www.vliz.be/imisdocs/publications/","SubDir":null,"InternalReq":0,"LoggedInReq":0,"Disclaimer":null,"DutchDisclaimer":null,"FileFormat":".pdf","FileDescr":"pdf","InsPub":1,"InsID":36,"FileFormID":6,"LendableFlag":null,"PublicFlag":1,"orderLib":"A","Notes":null,"AccConID":null,"AccessConstraint":null,"LicURL":null}],"litstyles":[{"LitStyID":7,"Style":"Dissertation"}],"thespers":[{"PersID":34578,"Surname":"Ronsse","Firstname":"Frederik","Initials":"F.","Role":"Promotor"},{"PersID":27554,"Surname":"Heynderickx","Firstname":"Philippe","Initials":"P.","Role":"Co-promotor"}],"arch2discl":null,"SERpubls":null,"MONpubls":null,"pictures":[],"thestermsPath":[{"ThesaurusTerm":"Marine environment","ThestID":4999,"Acronym":"ASFA","ThesTermPath":"Environments > Aquatic environment > Marine environment"},{"ThesaurusTerm":"Fish products","ThestID":3192,"Acronym":"ASFA","ThesTermPath":"Fish products"},{"ThesaurusTerm":"Korea, Rep.","ThestID":185709,"Acronym":"ASFA_GEOT","ThesTermPath":"Korea, Rep."},{"ThesaurusTerm":"Seafood products","ThestID":7310,"Acronym":"ASFA","ThesTermPath":"Seafood products"},{"ThesaurusTerm":"Waste management","ThestID":82241,"Acronym":"CSA","ThesTermPath":"Waste management"}],"thestermsASFA":[{"ThesaurusTerm":"Korea, Rep."},{"ThesaurusTerm":"Marine environment"},{"ThesaurusTerm":"Waste management"}],"taxtermsASFA":null,"geotermsASFA":null,"collections":[{"Collection":"OMA -
