Based on simulation data from stationary operating points, a mixed-integer nonlinear program including buffer storage, an electrolyser, a PV system, a battery and a PtM plant is constructed.

MSWI in Europe operate under strict regulatory requirements defined by the Industrial Emissions Directive (IED), resulting in very low overall emissions, including PCDD/F. A more recent and widely discussed group of pollutants are per- and polyfluoroalkyl substances (PFAS), which are thermally degraded to hydrogen fluoride (HF), carbon dioxide (CO<sub>2</sub>) and other thermodynamic end point compounds depending on elemental composition under complete combustion conditions. This study investigates the completeness of PFAS degradation in laboratory- and pilot-scale incinerators. The conversion of PFAS to HF is assessed using several analytical techniques for detecting fluorine-containing species in flue gas, liquids and solids, and their impact on establishing a consistent fluorine balance (F-balance). Depending on the analytical method employed, the achieved F-balance ranges from 59 to 100 wt% when ‘products of incomplete combustion’ (PICs) are not considered.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"98 9","pages":"600-606"},"PeriodicalIF":1.6,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.70137","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148872158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
