A waste heat recovery project succeeds only when four things line up: a source, a sink, compatible temperatures, and coincident timing. Miss any one and the economics collapse, however hot the source or however green the intent. This lesson turns that into a repeatable appraisal: the four conditions as a checklist, worked through with numbers that show how decisively the timing match, in particular, governs payback.
