Nice to hear you say that, Louis ;-)...
Not only are phosphates recoverable from the waste stream, but there is a world-wide phosphate shortage going on. Mined deposits are running out, apparently. China has, in response, put a halt to phosphate exports from its nation.
So it makes every bit of sense to recover as much phosphate as possible from the municipal waste stream. Additionally, even with phosphated laundry and dishwasher detergents, I've estimated that for an average family over 50% of the phosphates they send down the drain come from their own bodies - urine and feces, to be explicit.
Presumably the pseudo-environmentalists won't be demanding that we all go on phosphate-free diets (we would die in a matter of days)!
I'd also like to add that the ban on phosphates is something of a shell game. It allows operations to continue to pollute waterways with excess nitrogen, which is the MAJOR water pollution concern in the arid Southwest portion of the USA, not phosphates.
