A stage-based framework for closed-loop recycling of polymeric composite membranes.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Polymeric composite membranes are essential in modern separation technologies but pose critical challenges for sustainable end-of-life (EOL) management due to their chemically heterogeneous, multilayer structures. Existing approaches, such as mechanical processing or catalytic depolymerization, exhibit limited efficiency in separating and recovering multiple components. Here, we present a stage-based physical-chemical recycling strategy enabling multicomponent recovery and closed-loop regeneration of composite membranes through sequential solvent extraction, catalytic depolymerization, and membrane recasting. Using real EOL membranes as feedstock, the process yields regenerated membranes with mechanical robustness and separation performance comparable to commercial counterparts. Life-cycle assessment and technoeconomic analysis reveal substantial reductions in environmental impacts and material costs relative to conventional membrane manufacturing. By engineering a scalable process system for the circular recovery of complex membrane components, this work bridges materials science and process engineering, offering a viable route for sustainable management of polymeric composite waste streams.
