Description

Location: GLO - Global
In- and outputs are calculated from bastnasite ore composition mined in China. Infrastructure and land use approximated with iron ore mining. Some inputs of auxiliary materials are calculated according to stoechiometry. Rough estimation for energy consumption, wastes and emissions.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology
