process in the process chain. A connection between plans and processes by tracked
flows is also possible.
Waste flows are, not surprisingly, waste flows that require additional processing within or
outside of the current system but that remain within the technosphere.
3.19 Specifying flow types
You need to tell GaBi which of the entered inputs and outputs are tracked, waste or
elementary flows. When entering flows, the type of flow will be entered automatically by
GaBi. However, you can modify this if necessary.
44. Click in the „Tracked flow‟ field until the appropriate symbol appears.
Tracking a flow with an X or star indicates that these flows will remain in the technosphere
and represent a tracked flow and a waste flow respectively. This allows you to connect the
flow to another process or plan.
45. Steel wire is a valuable substance, so specify it as a tracked flow by clicking in the
„Tracked flows‟ box until an „X‟ appears.
46. Electric power is also a valuable substance,
47. And so is the paper clip.
Make sure that each of these flows displays an X in the tracked flows column.
We have now fully defined the paperclip bending process.
48. Click „Save‟ to save the process and close the process window.
3.20 Fixing and scaling processes
One very important step when creating a plan is to define the reference process. On every
plan one process should be fixed. This allows GaBi to calculate all results in relation to
this fixed unit. As you edited the paper clip bending process you specified the functional
unit of the process to be 1 paperclip. Now you can specify the functional unit of the plan to
be 1000 paper clips.
