This dataset represents treatment of used refrigerant R-12 by venting.
The refrigerant R-12 was a widely used refrigerant (mainly in automobile) and as aerosol spray propellant. It can be treated by two different technologies; 1) venting, and 2) final disposal.

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.
