mercury production, UPR, ecoinvent 3.6, Undefined
Location: GLO - Global
The functional unit represent 1 kg of liquid mercury. Large uncertainty of the process data due to weak data on the production process.
[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.
Data approximated with data from lime mining, crushing and milling plus estimation of the additional furnace operation step, based on information in literature and own assumptions.
