Banning stuff is rarely my preferred solution. My take on producer responsibility is that producers should be prepared to take their stuff BACK - meaning, if someone turns up at their headquarters (or some more reasonable location) with a dump truck full of, for example, empty coffee cups, they should be required to accept the delivery and find a way to dispose of it, paying for landfill if necessary, but hopefully something more constructive. I just want the cost of disposal to come straight back to them.

The coffee cup example is contrived, but let's say every producer of plastic zip ties was required to receive returned plastic zip ties each year, equal to the volume that they sold the previous year?
