Abstract
Plastics are indispensable in modern society, yet their rapid production and accumulation create urgent environmental and resource challenges. Because they are primarily composed of carbon, hydrogen, and oxygen, plastics can be viewed as a resource rather than waste. This perspective highlights chemical upcycling as a promising strategy to depolymerize plastics into intermediates for repolymerization or to convert them into high-value products. We emphasize advances in catalysts and processes that improve yield and selectivity while lowering energy input, alongside the integration of renewable electricity and solar energy to enhance recycling efficiency. Techno-economic analysis (TEA) and life-cycle assessment (LCA) are critical for evaluating feasibility, sustainability, and scalability. Finally, we outline how collaboration among researchers, industry, policymakers, and the public—through shared infrastructure, incentives, and cross-sector partnerships—can accelerate the transition to a circular plastic economy.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
