What it is

Per 1 t of calcium ammonium nitrate (about 27 % N), gate-to-gate, EU plants of the LVIC-AAF BREF data collection. Ammonium nitrate made on site from ammonia and nitric acid and granulated with ground limestone; feeds from stoichiometry with the sourced losses, utilities as midpoints of sourced ranges.

Exchanges per 1 kilogram of Calcium ammonium nitrate, granulated, about 27 % N

As exported: allocated and scaled to the reference product. Provenance: 3 calculated, 4 given, 2 assumed. Pedigree scores (1 best, 5 worst): reliability, completeness, temporal correlation, geographical correlation, further technological correlation.

Preliminary1 exchange is not yet linked to a background dataset. It counts no burden, so the inventory is incomplete: do not read a result from it as complete.

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
from cheme_as_code_lci import install

bd.projects.set_current("my-project")   # holds your licensed background + biosphere3
install("cheme-as-code-atlas-preview-a3c52e4.xlsx", background="ecoinvent-3.11-cutoff", location="DE")
activity = bd.get_activity(("cheme-as-code-atlas-preview-a3c52e4", "ammonium-nitrate-1:calcium-ammonium-nitrate-granulation:product:calcium-ammonium-nitrate"))

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.
