Technically, most medical practices do not generate any state-defined regulated medical waste. Individual tubes of blood or body fluids are almost always smaller than 20 ml. Urine, which is not considered medical waste unless it is visibly contaminated with blood or pus, may be disposed of by pouring it down the sink.
Human urine can be used directly as fertilizer or it can be put onto compost. Adding a healthy person's urine to compost usually will increase temperatures and therefore increase its ability to destroy pathogens and unwanted seeds.
