Every industrial symbiosis proposal dies in validation.This is the validation.

The question is never whether the stream has value. It is whether the numbers survive a technical review — and answering that has meant a feasibility study measured in months. Below is what replaces it: a route dossier computed from a real stream, where every reported figure is either derived from a balance that closed or is a declared input carrying its source.

Read the basis first

Every physical and per-unit figure above is stated per tonne of stream. The annual lines are that per-tonne result multiplied by a declared throughput. The engine output does not restate the basis on each line, so it is stated here.

The declared inputs behind the money

Natural gas at $12.50/MMBtu — client-declared, not a market forecast.
Throughput of 5,000 t/year — client-declared.
Exhaust temperature of 423.15 K — the recovery boundary assumed.

The annual figure is an arithmetic consequence of those three declared numbers. Change any one of them and it changes. It is not a promise, and it is not a quote.

What the tags mean

COMPUTED — derived from a balance that closed in this run.
[SOURCED] — a published reference value, carrying its citation.
[CLIENT] — declared by whoever supplied the stream. Never silently substituted.

Where the uncertainty went

The closing note records where an uncertainty band collapsed and exactly what collapsed it. A dossier that reports its own limits is the one worth checking; a number with no stated band is the one that fails review.

Why this survives review

A figure on its own answers a question. A closed balance settles it. Mass closes, energy closes, charge closes, elements close — and where a balance could not close, the dossier says so on the line rather than filling the gap with a plausible number. That is the whole property being offered: nothing in the output is asserted without either a closure behind it or a declared origin in front of it.
