Actually, this is covered by a different set of rules in the EU called 
WEEE which requires manufacturers to take back either gear that they've 
sold, or sometimes other people's equipment that they're replacing.  It 
actually went into effect last year (ahead of RoHS).

And, lots of other countries and several US states are getting on the 
WEEE/RoHS bandwagon, so it's going to be a pretty universal set of 
requirements before too long.
