Where this record's text came from. 2026-08-20 schema-0.3 pass: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
How to read this page. The article itself is not reproduced here — this paper is not cleared for redistribution, so what follows is the tag layer alone. The evidence sentences are withheld with the article. The table at the foot lists every tag the record carries; each row names the facet it belongs to, and the whose words column says whether the tag records the paper's own wording or the tagger's sentence about the paper. Every tag links to each other paper in the corpus carrying it. The machine-readable edition of the same thing is the TEI file beside this one, where the tags live in standOff, and the article is at its publisher via the link below. When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.

Tags on this paper

Every tag the record carries, each linking to every other paper in the corpus that carries it. A tag appears here whether or not its words occur in the article — the spans below are only the ones a sentence in this paper licenses. Of the 22 concept tags on this paper, all 22 are grounded in a quoted sentence.
plastics polymer resins synthetic fibers additives material flow model primary plastics secondary plastics recycling incineration discard rate final disposal microplastics packaging product lifetime distributions log-normal distributions sensitivity analysis pyrolysis monomers landfills municipal solid waste PP&A fibers CAGR NON-BIODEGRADABILITY CONVERTS PRODUCTION DIRECTLY INTO STOCK: because none of the commonly used plastics biodegrade, waste accumulates rather than decomposes, so every tonne made is still somewhere unless it was burned THE ONLY PERMANENT SINK IS THERMAL DESTRUCTION - combustion or pyrolysis. Recycling and landfill both keep the material in the system, which is why the accounting has an ever-growing discarded stock RECYCLING ONLY REDUCES FUTURE WASTE IF IT DISPLACES PRIMARY PRODUCTION, and whether it does is counterfactual and so extremely difficult to establish - the mechanism is stated together with the reason it cannot be measured MIXING AND CONTAMINATION DEGRADE THE SECONDARY MATERIAL, so recycled plastic is of limited or low technical and economic value and cannot simply substitute for virgin material SUNLIGHT FRAGMENTS RATHER THAN DEGRADES: weathering breaks the material into millimetre and micrometre particles without biodegrading it, which is where microplastics come from THE PROPERTY THAT MAKES PLASTIC USEFUL IS THE PROPERTY THAT MAKES IT PERSIST - durability and resistance to degradation are the same fact described from two sides, so the problem is not a defect in the material but its purpose PRODUCT LIFETIME DECOUPLES WASTE FROM PRODUCTION IN TIME: packaging leaves use the year it is made while construction plastic leaving use today was made decades ago, when volumes were far lower - so the waste stream's composition is not the production stream's THE SHIFT FROM REUSABLE TO SINGLE-USE CONTAINERS DROVE PACKAGING, the largest market, and packaging is the shortest-lived sector - so the market that grew fastest is the one that becomes waste soonest Global recycling incineration rates computational-model
Method, as described: a material flow model combining production statistics with log-normal product lifetime distributions for eight use sectors, and regional recycling, incineration and discard rates

The paper

The full text is not reproduced here. This article is not cleared for redistribution, so the page carries the tag layer only. Its evidence sentences are withheld; the grounding status remains with each tag, and the article itself is at https://doi.org/10.1126/sciadv.1700782. The reading view exists for the papers whose licence permits it.

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; none of 4 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.
