Overview

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

Description

Surovtseva, D, Crossin, E, Pell, R, Stamford, L. Toward a life cycle inventory for graphite production. J Ind Ecol. 2022; 26: 964– 979. https://doi.org/10.1111/jiec.13234. Green coke is further calcined to produce needle coke, and in this work composition of calcined coke was calculated based on compositions of green coke and volatiles. Relevant dataset covers operation of calcination unit / plant.

Note that the input of green coke from the original publication has been replaced by an input of petroleum coke, as it seemed incorrect and unllocated with other products co-produced with green coke.

Quality and maturity details Expand Collapse

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.
