Arguably the cost of a recycled battery is a charge on the use that the material is put to, not on the use that it WAS put to previously. ie you assume that the disposed of item has whatever value is placed on it when it enters the recycling scheme - positive if the recycler pays you, negative if they charge you and zero if they take it for free. Then the recycling operation calculates its own costs. As most originally high cost items, including batteries, will actually be paid for by a commercial recycler, and that would certainly include large batteries, then it seems reasonable to assume a zero value or greater for such items. And ecological and other costs are then borne by the recycler who presumably finds it cheaper to source their lead or cadmium or whatever from a pile of someone else's junk than from a mine. So, arguably, and it is arguable, a recycled battery is BETTER than no battery if the recycler will pay you for it, as it represents a lower cost resource than digging the material out of a hillside and processing it. I'm aware of the potential deficiencies in such an argument but it seems an accurate enough one to take at a simplistic level;. A major problem with "market forces" arguments, which this is one of, is that "the market" aka the invisible hand is a thief or a naive taker (depending on one's altruistic attitude). ie "the market" will acquire resource at the cost that it can, not at the cost that it "should" if all factors were considered "properly". "Should" has no meaning to 'the hand' - it deals only with "can". Friends of the hand deride 'should' as attempts at nannying and at corruption of true economic drive, and this may often enough be true, but "should" also arises from the use of intelligent vision to identify local and distant peaks in the cost benefit continuum. The hand is a dumb brute that can only crawl the local gradient in the same way that natural selection does, and may find itself stalled on a local peak without "realising" (as it has no brain" that true optimum, even by its own blind rules, lies somewhere else if only something were able to move it there. The 'valley" which the hand is unable to crawl down into and cross to reach the higher pastures elsewhere may be (and arguably usually is) caused by it misvaluing resources that it has questionable rights to. This assessment is not an attempt to inject social perspective per se but rather an attempt to understand reality. If eg an action impacts air quality or the disposal of 'divalent chromium, or lowers water table below the level where permanent pollution of an island's water lens will result (as per the misattributed example in "An inconvenient truth"), or ... and forces controlling "the market" have not caught up with such issues, or do not detect the impact, or the impact is not appreciated, then air or water or life quality may be degraded until such issues are addressed. In due course you end up with China or industrial Russia or, I imagine, Pittsburgh, and people may then start to act. But the true past costs are then being paid for by unrelated future actions. China is a good example, as I have just recently seen. What was for certain a once beautiful landscape is broken and battered beyond belief where-ever I looked. Throughout a 500 km train ride, and at every other point where I was able to observe, visual evidence that the environment had been horribly abused abounded. If they ever decide to "fix" this the costs of the past will be visited on the products of the future. I didn't notice any identifiable Prius batteries lying around.
