A Comparative Bibliometric Analysis on Plastic Waste Recycling
Bibliographic record
Abstract
The aim of this study is to explore the application trend of the circular economy and research on plastic waste recycling by comparing results from selected databases.The methodology involves developing a bibliometric study based on data from Scopus and the Web of Science Journals & Country Rank, spanning from 2014 to 2023.A total of 2,083 articles were retrieved from these two research databases, with 1,108 and 975 articles coming from Scopus and WoS, respectively.Descriptive bibliographic maps and strategic charts, generated by OriginPro, Excel, and VOSViewer, are presented.The Circular Economy (CE) is a model that eliminates waste, adopts sustainable practices, closes loops in industrial ecosystems, and turns end-of-life products into resources for others.This stands in contrast to the linear economy, which disposes of waste through landfill or incineration.Currently, plastic production is still supported by a resource-intensive paradigm that decouples economic growth from resource consumption.The annual consumption of plastic materials and fossil fuel is projected to triple by 2050, a trend that has attracted significant attention.The introduction of CE has drastically reduced resource consumption.This study compares the Scopus and Web of Science databases regarding current plastic use and recycling of plastic waste.Moreover, it identifies the future contribution of the degrowth economy in managing plastic waste for recycling.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
