At the Fan Fests for the world cup here in Germany there is a deposit system in place when you buy a beer (or any drink for that matter), which mean when you buy a €3.50 beer, it costs €4.50 as you have to pay €1 for the (plastic) glass, which you get back when you return the glass.
This great idea means much less litter is strewn around the festival sites, making the general environment much more pleasant for everyone, and probably much cheaper clearing-up costs.
What if we extended this to more areas of our lives? Can you imagine the hundreds of thousands of pieces of electronic equipment that are discarded every year in the western world. Mountains of telly's, piles of PCs and hills of Hi-Fi systems. And the majority of this 'rubbish' ends up in a dump, to be buried under ever more rubbish, ad finitum.
Surely most elements that compromise electronic equipment could be recycled and used in the production of newer equipment with a small amount of effort. Also, many electronic components contain toxic substances, such as mercury, lead and cobalt, which are hazardous to our environment if not properly disposed of (or reused).
How can we get people to be responsible with respect to recycling electronic goods? With a deposit system, as used by the Fan Fest organisers for glasses. When you go to buy your new HD 60 inch TV, you should have to pay a deposit (say 5% of the cost), which you only get back when you feel the TV has run its course, and you bring it to a place where it can be properly disposed of. This would probably stop most people from simply chucking electronic goods out at the most handy place available (i.e. the local dump site, or, if it fits, the bin).
Most people (and I include myself in this) most of the time, will think of the consequences only when it affects their wallet. Time to hit us where it hurts!
