bio-degradable for sure and it's certainly true that the call of nature is unavoidable at times: multi day wild camping demands that one craps somewhere, sooner or later.
i'm not sure what point you're making with your mention of using plastic bottles (surely that's a big wall affair and the idea in that scenario is to take the bottle away with you, not leave it lying around) and- fwiw- i think crapping in the wilderness is in fact ok as long as you spare other people having to come across it and make sure you're well away from water sources and so on. needs must... but what about common courtesy, eh?
this is on the first belay of a four pitch, low grade, easily accessible route (it's not as if someone had been stuck there with rumbling guts while their leader had a 6 hour epic leading the next pitch). i don't think that's unavoidable at all and it's a simple matter of showing consideration for your fellow climbers. like i said in a previous comment: if it was really necessary, then finding a more discreet spot with less traffic (say just a few feet below in the gully somewhere, prior to starting the first pitch) would seem reasonable to me, although others would probably find this to be unacceptable too.
you crap on top of needles? that just seems deliberately unpleasant, inconsiderate and vaguely fetishistic. or is this perhaps just a digestive system side effect of the arthrotec that you mentioned in another thread lately? hmmmm...
