Hi, everybody. I was away for few years.
Anyway, here's an issue I came across recently.
I tried searching on the forum, on the internet and even on the search engines of internation journals of academic research, with not much success.

Is there any company or organisation technically able to recycle poe oil?
I don't mean to dispose of it. I mean to be able to rework the polluted oil and return it back in the chain of supply, either as POE oil or lubricant/grease of some sort.
I've been stockpiling used oil from decommissioned compressors and would like to responsibly return it in a environmental-sustainable and circular way.

Thanks everybody.
