What the paper establishes

A complete elemental inventory of municipal manufacturing feedstock, stated per ton, per year and over 30 years. Unsorted material resolves into named elements, led by carbon, oxygen, hydrogen and nitrogen.

A feed basis for the process model. The paper reduces the inventory to the proximate and ultimate analysis the platform’s simulation uses, so the Recyclotron™ and OmniCrude™ papers start from the same measured numbers.

How it was measured

Sampling followed ASTM D5231: 200 physical samples at 90% confidence across a characterization base of about 1.9 million tons.

Every material class carries an exact, traceable literature citation, with a primary reference and confirming sources from US and European agencies and standards bodies. Composite categories are resolved into named elements, and the few small fractions with high uncertainty are flagged with explicit ranges rather than averaged away.

How certain it is

Combined uncertainty on total mass is about ±2.4%. Per-element uncertainty bands are propagated from the sampling margin and the reference-data variance, and the full paper states them element by element.

Why it matters downstream

The process conserves atoms, so the input fixes hard limits on everything after it before any operating decision is made. The carbon in the feed bounds the carbon in the outputs. Metals pass through the process unchanged, so the input inventory is the metal forecast. The chlorine and sulfur in the feed size the acid-gas capture duty.

Evidence status

Inventory values are certified against the cited reference basis. The small high-uncertainty fractions are flagged as such in the paper.
