The inventory refers to 1 productive machine hour (PMS) - referring to the operational time of the machine including breaks up to 15 minutes - of a terrain chipper mounted on a forwarder with a total weight of 19,610 kg (including the harvester).
A terrain chipper is a chipping unit for the chipping of energy wood in the stand. The chipping unit can be built on a specifically developed vehicle or combined with a forwarder. The dataset is representing the chipping with the chipping unit mounted on a medium-sized forwarder.
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.
