The data are compiled regularly usingan open source workflow, archived and versioned on Zenodo under aCC-BY license, then processed and displayed on FAIR-TPs.

A graph-based representationof the transformations (compounds as nodes and reactions as edges)is stored in a Neo4j database as a Directed Graph and made publiclyaccessible online through a Django Web Application. Users can retrievethe shortest directed pathways between predecessors (parents) andsuccessors (transformation products/metabolites), search by SMARTSsubstructures, or explore local reaction neighborhood data on individualcompounds. Interactive network visualizations provide ways for usersto view multistep transformations in a smooth, user-friendly interface,while exploring transformation pathways.

This study evaluatesa conventional chemical scrubber (CS) and a bioscrubber (BS) treatingsulfur-rich off-gas from a sulfur-based pigment plant. The bioscrubberintegrates anaerobic sulfate reduction and partial sulfide oxidationto recover elemental sulfur and biogas. Two BS variants were analyzed,differing in carbon source for sulfate reduction: fossil-derived pureglycerin (BS-PG) and purified crude glycerol (BS-PCG). Mathematicalmodels were integrated with life cycle assessment (LCA) and life cyclecosting (LCC). Bioscrubbing enables resource recovery but stronglydepends on the carbon source: BS-PG raises environmental impacts inmost categories and increases greenhouse gas emissions to about 7277tCO₂eq per year, compared with 1379 tCO₂eq forCS, whereas BS-PCG limits them to 1599 tCO₂eq and performsbetter than CS in several impact categories. Nonetheless, the energyand chemical demands for glycerol purification remain challenging.Sensitivity analyses identified gas flow rate, purge fraction, anddistance to disposal sites as crucial parameters, indicating thatbioscrubbing may be suited for medium-to-small plants. Economic analysisindicates that carbon source purchase dominates costs (≈1.6M€/year for BS-PG and 1.2 M€/year for BS-PCG), so feasibilityhinges on lowering glycerol prices and valorizing biogas.
