Using raw sewage sludge as the input of a process

Question

Hello,

I would like to use the “raw sewage sludge” as the input for a process, however there is no possibility to choose any provider, there is no dropdown menu shown. Do you know why this is not possible? Is it because it’s a waste flow?. I'm using the ecoinvent 3.6 database (cut-off unit).

Thanks for your assistance.
