Exchanges per 1 kilogram of Hydrogen peroxide 50 wt% to storage

As exported: allocated and scaled to the reference product. Provenance: 23 assumed. Pedigree scores (1 best, 5 worst): reliability, completeness, temporal correlation, geographical correlation, further technological correlation.

Preliminary15 exchanges are not yet linked to a background dataset. They count no burden, so the inventory is incomplete: do not read a result from it as complete.

The streams are the plant's own flows: an amount here is allocated and per 1 kilogram of Hydrogen peroxide 50 wt% to storage, so it differs from the stream's flow, and it can sum several streams.

Where these numbers come from: each exchange names its source above; the dataset is processes/hydrogen-peroxide-1/lca/dataset.yaml in library version c3ab348.

A file with this activity alone is not available: each file above is the whole database, and the line under it says how to find this activity there.

import bw2data as bd

While any exchange of the database has no mapping, install() writes nothing and only lists the unlinked exchanges. So the last line finds no activity until the gaps are mapped: the download section gives the ways to use the database now.
