Here, we analysed more than 20,000 synchronized operating records from a full-scale single-stage flash-tube MDF dryer at an industrial SWISS KRONO production line and linked total VOC (TVOC) measurements from flame ionization detection with Fourier-transform infrared speciation on the cleaned stack. Five compounds\u2014\u03b1-pinene, 3-carene, limonene, methanol, and formaldehyde\u2014accounted for more than 80% of the resolved VOC signal. Process\u2013state contrasts showed that higher digester residence time, discharge screw speed, adhesive amount, urea amount, dryer inlet temperature, and scrubber\u2013water temperature increased one or more representative compounds, whereas higher hardwood share, additional flue-gas supply, and higher scrubber\u2013water pH decreased them. Limonene, methanol, and formaldehyde were substantially more process-sensitive than \u03b1-pinene. An exploratory decorrelation step further showed that a drying\/throughput domain explained about half of the variability of the screened process space. The study therefore identifies the small set of compounds and operating domains that most strongly govern the cleaned dryer-stack signature and provides a mechanistically grounded prioritization framework for follow-up causal experiments, source apportionment, and emission-mitigation design in industrial MDF manufacture. Unlike product or chamber emission studies, this work links the compound-resolved FTIR\/FID chemistry of the final cleaned industrial stack with synchronized production variables; it therefore addresses a scale-integration gap by transforming routine compliance-type exhaust monitoring into a process-diagnostic framework for ranking emission sources, abatement-sensitive variables, and mitigation experiments.<\/jats:p>","DOI":"10.3390\/polym18101230","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T12:36:40Z","timestamp":1779107800000},"page":"1230","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Compound-Resolved VOC Dynamics in a Full-Scale Medium-Density Fibreboard Dryer: Process\u2013State Screening Across Wood Furnish, Amino Resin Dosing, and Thermal Operating Variables"],"prefix":"10.3390","volume":"18","author":[{"given":"Vladimir","family":"Nedi\u0107","sequence":"first","affiliation":[{"name":"Faculty of Wood Sciences and Technology, Technical University in Zvolen, T.
