What are the advantages of urine diversion?
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:
1) Reduced volume of material requiring sanitization and transportation. In urban contexts, where offsite composting is necessary, urine diversion can significantly reduce transport costs.
2) Less carbon cover material required to reduce odour and flies.
