There are some great ideas on here and the back and forth between ideologies is informative, however if we are honest with ourselves then we have to admit first that we can't possibly know the best end solution, what we can do though is keep bundling in, adding to and tweaking existing policies that are successful, such as @nradov suggests. By suggestion this I'm not saying that we don't need big changes nor am I suggestion we only tweak. What I am saying is that we need to actively build brick by brick onto existing methods that have worked, such as deposits. Deposits are a great way to enhance recycling and that's proven, so adding them to a wide range of other products makes a great deal of sense. Does anyone else have other successful policies such as this that could be suggested for expansion too? We should keep actively tweaking rather than sitting on our hands debating what's a great huge step forward when the reality is that small, steady tweaks would have an astronomical effect over 10-20 years with I imagine a very low failure rate to-boot.
