Extraction of carbon powder from pyrolysis of low-density polyethylene plastics and its application in composite laminates.
Article in MethodsX, 2025. 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
The escalating environmental concerns associated with plastic waste, particularly Low-Density Polyethylene (LDPE), have spurred research into sustainable recycling strategies. Pyrolysis has been developed as a viable technique for transforming LDPE into appreciated by-products, including carbon powder, which holds potential for advanced material applications. This study investigates the extraction of carbon powder from LDPE via pyrolysis and its subsequent utilization in composite laminates.•Araldite LY 556 and Aradur HY 951 epoxy resins are used to create the laminates, and carbon and kevlar fiber reinforcement are added in different weight fractions of 0 to 30 % in the intervals of 10 % of carbon char generated from LDPE.•Tensile strength (ASTM D638), flexural strength (ASTM D790), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR) and scanning electron microscopy (SEM) are used to do a thorough assessment of mechanical and structural features.•Incorporation of LDPE-derived carbon char significantly enhanced mechanical properties of epoxy-based laminates. At 30 wt % char, tensile strength increased by 75 % in carbon and 129 % in Kevlar composites, while flexural strength improved by 94 % and 196 %, respectively. SEM, XRD, and FTIR analyses confirmed improved interfacial adhesion, structural integrity, and filler stability, demonstrating char's effectiveness as a sustainable reinforcement.
