human urine is a good additive to compost, it is ammonium nitrogen and requires microbials to convert it to nitrogen. The key to efficient and quick compost is the overall Carbon to Nitrogen ratio, this should be 25-30(carbon):1 (nitrogen).Some Carbon rich materials (wet compost) would be fallen leaves, shredded newspaper (provided its using soy ink ), shredded card board, straw, sawdust, and woodships and Nitrogen would be greens you find this in kitchen scraps, fresh leaves, grass clippings, and so does manure. Along with moisture the consistency of a rinsed sponge ( not too much, will rob oxygen and be counterproductive ) it should begin to "cook" and break down.
