Yes, in theory, which requires from you the effort of packaging it up, paying postage, plan time to go to the post office, etc - or you could just throw it in the trash for exactly the same visible effect and be done with it. Even if people want to mail them back, this sounds like exactly the kind of task that will perpetually stay on the "I'll look into that when I have time" list, until they finally just want to get rid of it and throw it in the trash.

But it's good for shifting the blame, because then the pollution is not DaanTech's fault but those of individual consumers.

Doesn't this contradict what the article was saying? At least there was a quote from DaanTech somewhere that you have to have a cassette inserted to start a wash.
