List Version Source flow Name there Why this flow
EF 3.1 08a91e70-3ddc-11dd-96c3-0050c2490048 natural pumice The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 ae9f0beb-36b6-52da-94d2-d4899193725c Pumice This substance answers to the name the row carries; both name the same compartment.
ecoinvent 3.12 4402f445-984c-4728-be22-6f9aea1146b9 Pumice A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent 3.8 4402f445-984c-4728-be22-6f9aea1146b9 Pumice, In Ground A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
