1 · What the graph read from it

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.

2 · The registry

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

Plastics are indispensable in daily life, with both production and waste generation increasing annually. As the world strives for net-zero emissions, advancing plastic recycling technologies has become a global priority. Pyrolytic liquefaction is a promising approach for recovering chemical feedstocks, including fuel fractions, from waste plastics, potentially substituting petroleum resources. Since the 1970s, research on pyrolytic liquefaction has progressed globally, and several industrial-scale plants are now in operation. However, to accelerate the transition to a circular economy, it is crucial to bridge the knowledge gap between lab-scale research and industrial-scale implementation of pyrolysis-liquefaction technologies. This review provides a comprehensive analysis of the current state of plastic recycling, the progress and challenges in cutting-edge lab-scale research on pyrolytic liquefaction, alongside the latest trends in industrial-scale liquefaction projects. It reveals that pyrolytic liquefaction of a wide range of plastics-including halogenated plastics and poly(ethylene terephthalate)-has been extensively studied at the laboratory level. In contrast, industrial-scale operations often focus on more common, easily pyrolyzed plastics and generally avoid the use of catalysts. This highlights the urgent need to develop robust, reusable, and cost-effective catalysts, as well as optimized process designs, to expand the range of plastic feedstocks suitable for industrial-scale pyrolysis plants.
