Urine is an excellent source of plant nutrients, however it is extremely heavy and difficult to transport. Mixing urine and poop also leaves toilet contents wet, which can cause increased smell and odours unless carbon cover material is significantly increased as well. For ideal composting, urine should be integrated into the compost pile to increase the final nutrient content, however it is often advisable to separate the urine from the poop in the toilets themselves to meet the following objectives:
- Less carbon cover material required to reduce odour and flies.
- By diverting the urine you end up having a dry mixture which allows aerobic composting happening which is less smelly than anaerobic composting
- Reduced volume of material. Solid human waste is approximately 85% water by volume. This means that a urine diverting toilet will have enormous capacity for its size. The solid material dries out and shrinks dramatically (just like a compost pile in your backyard). Urine diversion therefore also significantly reduces the weight of the waste in the bucket/wheelie bin.
