The section limits what a homeowner can compost to only the garbage wastes generated from that person's own domestic residence; it expressly prohibits composting any other garbage waste, which rules out bringing in yard debris, food scraps, or other organic material from neighboring properties, a business, or anywhere off-site.

16 (Solid Waste Collection and Disposal) alongside the container and storage standards, the same enforcement authority, the department of health and human services, oversees composting complaints, and a pile that draws rodents or flies or creates odor can be treated as noncompliant even if the composting itself is otherwise permitted.
