I don't know if you are a listener of the
podcasts, Karen, but Paul has a number of episodes dealing with the topic of urine. He has one devoted exclusively to the topic of women peeing outdoors.
Human urine, as I understand it, is sterile and healthy for use as fertilizer in most cases (excepting on root vegetables for raw consumption like carrots or radishes) from healthy humans.
People who've discussed it on the forums here advocating
bucket storage usually suggest a tight-fitting lid, some kind of liner, usually a paper bag,
newspaper, or rarely plastic bag (though I suppose you could use the compostable kind) containing some kind of
carbon absorption medium, like sawdust or
wood chips. You could chop up your Christmas tree or someone elses and use that, which offers the added benefit of the scent of the tree. Or a mixture of all three, for diversity in edge and more aeration.
I think an incinerator toilet has less to do for urine than for the breaking down of persistent chemical contamination in human feces. This either requires, it seems to me, a situation where lots of high-temperature waste heat is already available, or a
solar dehydrating approach and a series of stacked functions that lend themselves to
biochar and require drastic measures for controlling chemical contamination.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
