Between 2025 and 2030, Europe’s plastic‑to‑fuel (PtF) industry shifts from scattered pilots to scaled clusters linked to refineries and chemical crackers. Germany emerges as a hub for standardized feedstock preparation, advanced pyrolysis reactors, and emissions‑controlled upgrading, while the Netherlands and Belgium anchor offtake via integrated petrochemical complexes. Three reactor lanes compete and converge: fluidized beds (throughput, heat transfer, stability), auger/screw (compact, modular, mixed‑waste tolerance), and catalytic fixed‑beds (higher liquids yield/quality, tighter feed specs). Across the period, yields improve 6–8 points and specific energy use falls as heat integration and control systems mature. Emission control moves center‑stage. Best‑available techniques include staged thermal oxidizers or RTOs, acid gas scrubbing for HCl/HF, activated carbon for dioxins/furans, low‑NOx burners, and continuous emissions monitoring (CEMS) for VOCs and particulates. Post‑cracking, hydrotreating/upgrading units reduce sulfur, nitrogen, and oxygenates to meet refinery/chemical specs. Co‑processing with FCC/hydrocrackers requires tight contaminant control and traceability.
