Combining several processes into a product system

[ValentinY]

Hello,

I am new at openLCA and LCA in general and this might be a silly question. I am using ELCD free database to create a product system for a construction of a protective surface cap (very basic data input). I used some flow processes for the materials production, but there is no lorry transportation flow available to add it to the Protective cap process I created. However there is a separate Transportation by Lorry PROCESS available in ELCD database, but I don't know how to add it to the Product system. When I create the product system, it asks to connect it to the reference process (only one) and I have to pick the one I created - Protective cap. How can I add available Lorry Transport PROCESS to the same Product system so I can account it for? I will appreciate any input.

Thank you,

Valentin

Hi Valentin,
there are two main ways:
1) you can right-click on the process box and let openLCA find providers for the products that enter this process, and then add and if you want connect them;

2) you can drag a process into the model graph, from the process category tree, and then connect by dragging a product flow with your mouse. The suitable / fitting product is highlighted.

Thank you. I am still having some difficulties, but I'll play around and see if there is something I'm doing wrong.
