Procedure
Waste flows are, not surprisingly, waste flows that require additional processing within or
outside of the current system but that remain within the technosphere.
3.16 Specifying flow types
You need to tell GaBi which of the entered inputs and outputs are tracked, waste or
elementary flows. In the tracked flows column, you need to select an X for a tracked flow,
a star for a waste flow or leave it blank for an elementary flow.
44. Click in the „Tracked flows‟ field until the appropriate symbol appears.
Remember that tracking a flow with an X or star indicates that these flows will remain in
the technosphere and 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.
We have now fully defined the paperclip bending process.
48. Click „Save‟ to save the process and close the process window.
3.17 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 with reference
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.
49. Double click on the „Paper Clip Bending‟ process and enter a scaling factor of
„1000‟.
50. Select „Fixed‟.
Now the processes and flows on the plan will scale to reflect the amounts required to
manufacture 1000 paper clips. We could also scale the fixed process to 500 paper clips or
1 million and all flow amounts would change proportionally.
