Overview

Scope, source, release context, and stable identifying information.

Description

This dataset represents production of disodium disulphite as an inorganic sulfur-based process chemical used in the cobalt-processing foreground inventory. The underlying chemistry is consistent with Barbera et al. (2012) on sulfites, thiosulfates, and dithionites, with life-cycle inventory support from Hischier et al. for industrial chemical production. It should therefore be interpreted as a chemical input rather than as a cobalt-specific end product.

Quality and maturity

TRL scale Higher is more mature. 9: routine commercial deployment 8: commercial, but still niche or scaling 7: first-commercial or advanced demonstration 6: engineering-scale demonstration 5: pilot or large prototype 4: bench or lab validated 3: research-stage concept Technology readiness level
1 to 5 scale Lower is better. 1: strong market- or operating-data basis 2: commercially plausible, but still somewhat specific 3: partly representative, with modelling or adaptation bias 4: pilot, proxy-based, scaled-up, or prospective 5: weak representation of the real technology state Technological representativeness
1 to 5 scale Lower is better. 1: geography matches the claimed scope well 2: regionally credible, but broader or less exact 3: generic regional or global proxy 4: weak proxy or clear geographic mismatch 5: geography is effectively unsupported Geographical representativeness
1 to 5 scale Lower is better. 1: current for that technology class 2: slightly dated, but still good 3: dated enough to need caution 4: stale, pilot-era, or prospective relative to current practice 5: clearly not representative of the current state Temporal representativeness

Missing exchange uncertainty generation: Not requested

Representativeness scores use a 1–5 scale when provided. Lower scores indicate a closer fit to the modeled technology, geography, or time period.
