Sustainable polyolefin upcycling using liquid organic hydrogen carrier based hydrogen delivery and hydrocracking.
Article in Nature communications, 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
Globally, 89% of post-consumer plastic waste is landfilled or incinerated, exacerbating environmental pollution, while less than 0.1% is chemically recycled. Polyolefin plastics, nearly half of global plastic production, can be converted into liquid fuels via hydrogenolysis or hydrocracking but require external hydrogen gas. Here, we report a tandem catalytic process combining decalin dehydrogenation with polyethylene hydrocracking, eliminating the need for external hydrogen by using decalin as a liquid organic hydrogen carrier. Among several Pt/zeolite catalysts evaluated, a bifunctional Pt/HZSM-5 catalyst is identified as the most effective, achieving high PE conversion and selectivity toward liquid fuels. Comprehensive techno-economic and life-cycle assessments are conducted for three configurations: a one-step tandem reaction that directly integrates decalin utilization, a two-step process where dehydrogenation and hydrocracking occur sequentially under hydrogen-rich conditions, and an H
