Reminds me of the saga with car batteries. For years, those who sold them would take the old ones and pass them back up the chain to the manufacturers. They used to get something like 70% of the old batteries back which they recycled. There was no payment through the chain for this AFAIK. Then came regulation on disposal (of lead, I think). Government decided that it had to have a paper trail for each returned battery to ensure they weren't being dumped. At the stroke of a pen, the recycling rate plumitted, as there were now forms to obtain, fill in, and offences committed if you didn't. So the chain just stopped taking them back and they mostly went into landfill.
