FormerWMDriver / I was able to tour the Waste Management - Tampa Bay Area - Material Recovery Facility (MRF). MRF is pronounced like "merf" just in case you are wondering. This location processes a large amount of recyclable material from all around the Tampa Bay area. I was simply stunned at the size of the facility. This is the biggest recycling center I've seen!
I do not know the specifics about this process, and this video is a simple overview of the sorting process. This video is based on my interpretation of the processes I saw, and my interpretation may not be 100% accurate.
