Process Simulation of 1,4-Cyclohexanedimethanol Production from Waste PETs.
Article in ACS omega, 2026. 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 increasing accumulation of plastic waste, particularly poly-(ethylene terephthalate) (PET), necessitates sustainable recycling strategies. This study presents a process design for producing 1,4-cyclohexanedimethanol (CHDM) via chemical recycling of post-consumer PET using bis-(2-hydroxyethyl) terephthalate (BHET) as an intermediate. The proposed process includes PET glycolysis followed by BHET hydrogenation and was modeled and simulated using Aspen Plus and Aspen EDR. A production capacity of 7920 tons of PET annually was selected, resulting in 5000 tons/year of CHDM with 97.4% purity. Thermodynamic models (POLYUF, POLYSL, and NRTL-HOC) were applied across various process stages. Kinetic parameters were derived from the literature and simulation databases. Equipment sizing, energy integration, and economic analysis were performed, and the total production cost was estimated at 46.7 million USD. A profitability analysis via CAPCOST revealed a net present value of 4.39 million USD, a discounted cash flow rate of return of 16.14%, and a discounted payback period (DPBP) of 3.8 years. These results indicate that CHDM production from PET waste is both technically and economically viable, providing an environmentally friendly valorization pathway for plastic waste.
