Long term haybale urinal?

We are looking at building a two-bin composting loo (separate seats for pee and poo) for our family of 4 (2M, 2F). I've used a haybale urinal at short permie events, but wonder if anyone has ever used one longer term.
Our plan is to use small (80 litre) wheelie bins (that would probably only hold half a bale), and just peeing onto the surface.
Any thoughts on how that would go odour-wise and how long the bale would last? We would vent the bin.

Let me preface this by saying that I have ZERO experience with haybale urinals.

I would not put the strawbale into any sort of receptacle that would prevent excess liquid from draining out onto the soil.

I would also include LAB to keep smells down.

Richard,

I have just one small point to add.  You said you were wanting to use a small hay bale.  I assume that you meant a straw bale instead.  Straw will help balance out all the nitrogen in your urine and hay will get severely overloaded with N.

Just a small point,

Eric

So drain holes in the bottom then! Thinking of the bin as easy to remove, empty and clean.

I'd go a step further and suggest that you want good airflow around the bale, especially if it's getting saturated.

I did an experiment like this for a very short time once. I don't believe it lasted two weeks. The smell becomes vile very soon, and if you try to move the bale, boy, are you in for a treat. I consider it one of my many failed experiments.
