I am using ELCD database for my research work. In the results there is a process named "container glass". I don't understand its relation and usage in my assessmemt ?

Thank you in advance for your supports.

Regards.

I was confused by this. I think that the issue is that the waste flow "spoil" is produced by lots of processes but that the only process (in the ELCD database) that consumes it is container glass, so openLCA connects it in, even when there isn't a real link to the main process. I think you can swap it out for another process to deal with the spoil

So, it's basically a placeholder for generic trash?
I have a similar lack of understanding as OP. I have Electricity (Provider: Electricity Mix, consumption mix, at consumer, AC, 1kV - 60kV) as an input in one of my processes.
When calculating the results, the contribution tree shows that glass container associated with that electricity is a major driver for many of the Impact Categories.

Given its importance in the results, I would like to better understand what it stands for.
Could you maybe help me out here?

Thanks and regards

Hi Matt, no, I think that the issue is that ELCD doesn't haven an appropriate process built in to deal with the spoil resulting from the electricity generation. It therefore default to using glass container production as the way to getting rid of the spoil (as it uses some of it). Obviously, you'd need to produce LOTs of this to deal with the spoil and this therefore has a big impact. You could add another process that has spoil as an input (i.e. that then deals with it) and then link that as the default.

It is glass collected in containers, from households, from glass used for bottles and so on in packaging.
