Well, I wasn't referring to 50 year old ads with Indians. Rather that only a small percentage of plastic productd are eligible for recycling, and even that is going to end as China is no longer accepting plastic imports for processing and it's too expensive for certainly the US to take on. Maybe India will pick up the slack but for now it's all more landfill material. Besides, with residual nicotine it's automatically not considered for processing as it would have to be cleaned as some sort of hazmat material. A single pod might not contain much, but a pile of several hundred isn't something you'd want to be grinding up without some sort of protection and method to adequately clean the plastic (and separate out the metal and wick material).
Any single use plastic product, other than maybe sterile medical items, is a waste of good oil and takes up more landfill space. That to me is a problem and I don't view larger and larger landfills as environmentally friendly, or all that neighborly either. We're not out of landfill space by any means, but it's getting more expensive to ship it further and further to distant locations that will accept the crap. That's a negative environmental impact to me, and still aesthteticaly unpleasant on the side of the road. Just like McDonald's boxes and other trash thrown out the window of both cars and some apartment windows in certain neighborhoods.
