i never knew it was illegal.
as at the nursing homes i have worked in we just thrown the used adult diapers into the regular bin not contaminated waste.

as it is classed and everyday human excreetion.

only excessive bklood or contaminate bodily fluid needs to be incinerated.

i dont flush the poo down the loo.

to me human blood is just as bad as poo, if not worse. all bad organisms and contractable diseases are transmitted through both blood and poo and wee and any human excreation actually so i dont see why "poo" is singled out.
it is still ok to thrown your sanitary pad away or tampon but not your childs poo
