Pour the contents of your cup in a glass dish, cover it with a piece of cloth or paper and let it sit under the sun to dry. This dried menstrual fluid can be made into a powder and stored in a closed jar. Add water to reconstitute this powder and use it to paint or to fertilize your plants.
In cases of blood-transmitted infections, you should consider disposing of the contents of your cup directly into a biological waste container.
Keep bags for biological waste at home and get a small, rigid, dark-colored plastic container with a lid that seals. Bring the container with you when you go out, and when you empty your cup into it, add some toilet paper to absorb the liquid and make it easier to pour into the biological waste bag when you get home. Wash the container thoroughly every night, and make sure you securely close the biological waste bag and keep it away from pets and kids. When you finish your period, you can dispose of the biological waste as indicated by the laws of your state or country.
