In contrast, an LCI Result contains the entire life cycle data for part of or for the complete
life cycle of a product system. This kind of dataset is often referred to as a cradle to gate
or system process.
A partly terminated system, represented by p-agg, contains all LCI data for the process
except for one or more product flows that require additional modelling. For example, the
steel wire process is a partly terminated system because all of the inputs and emissions
for the process are accounted for except for the type of steel being used to make the steel
wire. This process type is sometimes referred to as a partly linked process.
The last process type is called an avoided product system and is represented by aps. This
can be a confusing process type because all input and output flows are set to negative
values or all inputs are converted to outputs or vice versa. This kind of dataset is typically
used when modelling allocation and shows the way that the use of certain materials and
energies is avoided by the product system under study. We won’t go any deeper into this
process type.
Take a guess what kind of process paperclip bending might be. Is it a unit process single
operation, unit process black box, LCI result, partly terminated system or avoided product
system?
If you guessed unit process single operation you are correct. But why?
Well, because this process represents only the process of bending the paperclip. It does
not contain multiple process steps, does not contain life cycle data for a complete life
cycle of a product system, LCI data and does not include negative flows.
3.12 Specifying the flow type
In GaBi you can specify the process type by selecting the appropriate type from the type
drop down menu.
27. Since the Paper Clip Bending process is a unit process single operation, you can
go ahead and select „u-so.‟
