Well, that was the most hilarious way my colony died so far.
A few days ago I decided to give Oscar a chance and try his recycle mod. At first everything was going great, we were building monuments from compressed trash and were happy.

Then I decided to start recycling waste into metals and fucked up crafting bills.
There were a couple dozen radioactive packs at the base and by the time I noticed, almost everyone had a critical toxic buildup.
In my defense, I will say that there were several raids, a caravan and imperial "helpers" who were constantly trying to break something or kill someone. And btw, all my colonists except one had 80% environmental tox resist from vac helmets (there was toxic fallout, lol)

Didn't expect this shit to be 10 times more toxic than the nuclear waste from Rimatomics.
This is a military grade weapon of mass destruction. Good to know.

Time for another restart.
