Parametric Life Cycle Assessment of Chemical Recycling of Nylon-6 to Caprolactam.
Article in Environmental science & technology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Chemical recycling is gaining attention to advance the circular economy. This study presents the first life cycle assessment (LCA) of real-world waste polyamide 6 (PA6) remonomerization to caprolactam, evaluating four depolymerization routes: acidic, hydrothermal, alcoholysis, and alkaline. We established an automated Python-Aspen Plus-LCA workflow, systematically mapping variations in PA6 waste composition and key process parameters onto probability distributions of environmental impacts. Results show that the hydrothermal process has the highest impacts in six of nine categories, while the solvent-free, alkaline NaOH route consistently shows the lowest. Despite lower energy demands, the acidic H
