Republic Waste Facility on Fire in Chicago (on 11-7-2019) 4K

I was driving along and I heard a light explosion right around the corner from where I was in Chicago on 11-7-2019, I looked up in the sky and saw a huge plume of black smoke, I thought it was the coffee roaster nearby but the smoke just got worse within seconds.
I drove down the block to the location of the fire which turned out to be Republic waste Management Facility on Wood and Carroll Street, I first took a looked around made sure nobody needed any help, who wants to be near a pile of garbage anyway, and then took a video of the entire fire.
It seems like the fire was started either from a lithium battery or from spontaneous combustion in the garbage, or who knows what else, i'm sure there is methane gas coming off of the garbage which could be ignited I'm sure.
Either way, the Chicago Fire department got that fire completely under control in like 10 minutes flat.
