I have heard that the men in the orange jumpsuits sort trash at the landfill, with or with out the blue bag. If that is the case, why use blue PLASTIC bags to separate trash that will be sorted any way
The recyclables must be clean and paper must be dry in order for it to get recycled. If the clean recyclables are thrown in with the dirty garbage, they will not get recycled. That is where the blue bags come in. They are helpful in presorting garbage from clean recyclables, but yes, when they are all crushed in with the dirty garbage, the recycle percentage of garbage probably decreases, but it is still likely to be much higher than no separating of the clean recyclables from the dirty garbage. I still don't know why they don't have separate bins on the trucks. In Asheville, where I last lived, they had one truck which made garbage and recycling pickups once a week. Homes were issued recycle bins and garbage bins. Aluminum, steel, and plastic went in one bin, and paper and cardboard into the other, with garbage going into the garbage bin. The truck would stop, one guy would grab the garbage and dump it in the back, while the other guy would grab the two bins and throw the contents into separate containers on the truck. They were actually faster than the guys here who dump just one can, and sometimes leave garbage in the bottom of my can.
