Assessing the Feasibility of Bioscrubbing for Flue Gas Treatment and Sulfur Recovery: A Comparative Study Using Mathematical Modeling, Life Cycle Analysis, and Life Cycle Costing.
Article in ACS environmental Au, 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
Industrial flue gas emissions are treated with technologies such as wet flue gas desulfurization (FGD) in chemical scrubbers, which are costly. Two-step biological scrubbers have emerged as an alternative for bio-FGD. However, no holistic technoeconomic and environmental comparison of both approaches is yet available. This study evaluates a conventional chemical scrubber (CS) and a bioscrubber (BS) treating sulfur-rich off-gas from a sulfur-based pigment plant. The bioscrubber integrates anaerobic sulfate reduction and partial sulfide oxidation to recover elemental sulfur and biogas. Two BS variants were analyzed, differing in carbon source for sulfate reduction: fossil-derived pure glycerin (BS-PG) and purified crude glycerol (BS-PCG). Mathematical models were integrated with life cycle assessment (LCA) and life cycle costing (LCC). Bioscrubbing enables resource recovery but strongly depends on the carbon source: BS-PG raises environmental impacts in most categories and increases greenhouse gas emissions to about 7277 tCO
