though not a "legal" answer i have observed...
where pet waste is bagged at municipal parks incl dog parks and aong sidewalks where folks regularly walk their dogs i find signs instructing pet owners to pick up after them and dispose of the waste where there are only common waste recepticals available
Vet Clinics and pet boarding facilities dispose of their waste in common trash recepticals
OMHO(not a legal definition) POOP IS POOP
i have no problem with it being placed in trash bins/dumpsters when it is mixed/covered in a mixture of kitty litter or the sawdust/peat moss mixture and bagged just like folks do w/ their cat box waste
just my personal OPINION
