Experimental and Analytical Tools for the Chemical Recycling of Engineering Plastics - A Multi-Scale Pyrolysis Study on Polydicyclopentadiene.
Article in Macromolecular rapid communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The creation of a circular economy for plastics is essential for a sustainable future. Currently, established recycling processes are not universally applicable. Pyrolysis can complement current recycling through the conversion of complex plastic wastes to condensates and gases for reintroduction into chemical industry processes. A multi-scale approach for the characterization of pyrolysis properties is presented using the example of polydicyclopentadiene. Pyrolysis-GC-MS (µg-scale), thermogravimetric (mg-scale), and lab-scale (g-scale) pyrolysis investigations are complemented by high-resolution product analytics. In Py-GC-MS, 1,3-cyclopentadiene is abundant, hinting at depolymerization as a dominant decomposition mechanism. In thermogravimetry, approx. 20 mass-% of the sample is converted to solids. On lab-scale, secondary reactions influence the product yield and spectrum significantly, indicated by a solid yield of ≈40 mass-%. Polydicyclopentadiene exhibits a broad product spectrum comprising unsaturated hydrocarbons and aromatics. In the condensed product, no 1,3-cyclopentadiene is detected, indicating recombination or derivatization reactions. Significant solid residue formation emphasizes scaling effects. The employed analytics provide comprehensive analyses of condensed and non-condensed products. With the presented approach, primary and secondary mechanisms can be resolved and crucial process parameters identified. In this way, a powerful toolset for the development of robust pyrolysis processes that aid in achieving circularity for plastics is provided.
