coke, by mass

Screening proxy coke, per kg as fired, as energy (Atlas unit proxy), GLO: the inventory of 1 kilogram of its reference product, attributional, cut-off.

proxy:coke-kgReport a problem with this dataset
Research outputAn inventory from a research design at the design maturity its process states, not verified plant data: check its calculation maturity and review status before use. Background activities are referenced by name only; no background data is included. All caveats

What it is

Converts coke counted by mass to the background's energy; the conversion uses soda-ash-1's coke analysis.

Exchanges per 1 kilogram of coke, by mass

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

How to use it

Downloads

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-c3ab348.xlsx", background="ecoinvent-3.11-cutoff", location="DE")
activity = bd.get_activity(("cheme-as-code-atlas-preview-c3ab348", "proxy:coke-kg"))

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.
