Is Humanure Compost Legal in Your Local Area?

Understanding Humanure Composting Regulations

Humanure composting, also known as sewage composting, is a process of composting human waste to create a nutrient-rich fertilizer. However, its use is heavily regulated due to health and safety concerns. In the United States, the EPA recommends that humanure composting be done using a thermophilic composting process that heats the material to at least 131°F (55°C) for an extended period to kill pathogens.

Local Ordinances and Zoning Restrictions

Local laws and regulations can significantly impact humanure composting practices. Homeowners may face zoning restrictions or permits required for composting human waste, even if they follow safe and sanitary practices. It’s essential to check with local authorities, such as the county health department, zoning board, or building department, to determine if humanure composting is permitted in your area. For example, some areas may require a permit or have specific guidelines for composting human waste, such as the use of a septic system.

Best Practices for Composting Humanure

If humanure composting is allowed in your area, follow strict guidelines to minimize risks. This includes using a dedicated composting toilet or septic system, ensuring proper ventilation and temperature control, and following a well-documented composting process. For example, the Humanure Handbook recommends using a composting toilet that uses a carbon-rich bedding material to absorb moisture and odors. By following best practices and adhering to local regulations, you can safely compost human waste and create a valuable fertilizer for your garden.
