Ecofriendly Upcycling of Poly(vinyl chloride) Waste Plastics into Precious Metal Adsorbents.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Global interest in the recycling of precious metals (PMs) in various industrial sectors has spurred the exploration of high-performance PM adsorbents. Unfortunately, many adsorbents exhibit unsatisfactory PM adsorption performance and require complex fabrication protocols and toxic chemicals. Hence, further development of simple, efficient, and eco-friendly adsorbents is necessary. Herein, poly(vinyl chloride) (PVC) waste plastics are simply transformed into high-performance PM adsorbents via benign solvent treatment and hydrazination. The resultant hydrazine-functionalized PVC (h-PVC) plastic can effectively recover gold, palladium, and platinum from real-world leachates owing to its combined reduction and chemisorption mechanisms. The PM-adsorbed h-PVC plastic can be regenerated, calcined into high-purity PMs, or directly employed as a catalyst, demonstrating its practical feasibility. Techno-economic and life-cycle assessments reveal that the h-PVC plastic-utilizing industrial-scale recovery of gold from electronic waste is cost-competitive and environmentally advantageous. The strategy supports environmental and sustainable technologies by enabling the sustainable maintenance of carbon and PM resources and provides an efficient and sustainable method for fabricating advanced adsorbent materials.
