This is a very un-republican thing to do, but as another poster mentioned, you could apply a tax/penalty/whatever to companies when their products are accepted into landfill sites. That would get passed on to consumers until it was cheaper to simply keep them out of landfills. Presumably your quality would go up in order to keep more of the profits of selling the units in the first place.

Not sure it would work in reality, but an interesting idea that is actionable by the government.
