Electrocatalytic Upcycling of PET Waste to Chemical Products and Fuels Coupled With Cathodic Reactions
Bibliographic record
Abstract
Plastic waste continues to be a major environmental challenge, worsened by energy-intensive conventional recycling methods that require highly pure feedstocks. In this review, emerging electrochemical upcycling technologies are critically examined, focusing on the electro-oxidation transformation of polyethylene terephthalate (PET) into valuable chemical products. Key reaction pathways and target products are outlined to clarify the selective electrochemical reforming of PET. The key focus is on the integration of anodic PET oxidation with complementary cathodic reactions, including water, carbon dioxide, and nitrate reduction reactions, to demonstrate how integrated systems can simultaneously transform plastic waste into valuable products and generate sustainable fuels. Furthermore, a techno-economic analysis is provided to highlight the essential factors that will influence the transition towards industrial-scale implementation. This review is intended to advance new research approaches and innovative strategies for improving electrochemical PET recycling techniques, supporting broader goals in circular economy growth and sustainable chemical manufacturing.

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.
