This. It's about what people find convenient or not. In my building we collect recycling separate from garbage. Each chute room on each floor has a recycling bin and there is a list on the wall of what all is and is not accepted. NOT accepted are #6 plastics, plastic bags (even if they have a recycling mark on them), paper towels, facial tissue, pizza boxes, etc. It's not really a long list, but it does require people to distinguish one from the other. Do they do that? No. So when the building maintenance crew comes daily to collect recycling, if they see that in someone's bag left in the bin some of these NOT items, that whole bag gets tossed. It's not that difficult to distinguish what is and is not and to separate accordingly. We're also supposed to rinse cans and jars otherwise we get charged by the company more for this. Again, not that hard. I keep a small waste receptacle under my kitchen sink and I rinse and toss my (acceptable) plastic containers, jars and cans, then take it to the chute room when its full. Not so hard. But people won't even do this little bit. And for things not accepted by our building's recycler, the city has drop off locations for tons of other stuff. And the city's website provides information about a host of other places to drop stuff. But, again, it requires a bit of time and isn't always super convenient ... but it's just not that difficult. If only people would just do this little bit. Many do ... but many don't.
