Procedure 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 paper clip 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 paper clip. 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.’ 38
3.13 Parameters Procedure Here you see the parameters area. By entering parameters, you can create what if scenarios as well as determining certain aspects of this process’s relationship to other processes. The parameter area is closed for now and for now we will not go deeper into this. You now see a series of tabs. Since GaBi is designed to carry out a large variety of evalulations, it is possible to enter additional information relating to financial analysis and life cycle working environment. 3.14 ILCD Documentation You can also add ILCD documentation. For the time being we will focus on the current LCA tab. You have the possibility to enter additional information relating to this process such as its year, region, completeness and additional comments. Adding this information improves the quality of your process information but does not affect the results calculated by GaBi. You can enter some information here if you like or carry on. 3.15 Entering inputs and outputs You can see two display areas called inputs and outputs. In the input field all flows that enter the process can be entered. These inputs could include different forms of energy, like compressed air, electricity or thermal energy, as well as materials or other consumables like lubricants. On the output side all flows that leave the process are entered. You can for example enter the products and by-products that are produced and also the wastes and emissions arising from the process. Let´s start by entering an input flow. To fold the paper clip you obviously need steel wire to fold. 39
