Eliminate standing heat losses (insulation — typically 2–5% of fuel, <2-year payback), fix steam traps and leaks, then waste-heat recovery. Fuel switching and CCS cost 10–30× more per tonne.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:
