You don’t need to purchase a commercial composting toilet to safely recycle human waste. A simple setup of a bucket, seat and sawdust — giving these toilets the name “sawdust potties” — will do. We asked members of our Facebook community about their experiences with DIY toilet setups, as well as any building or sanitation codes they had to follow. Their consensus? This natural method is unexpectedly inoffensive, and it saves water to boot. — MOTHER

I’ve lived with a DIY composting toilet for 13 years. I’ve used just about everything as a composting medium, including pine shavings, coco peat, peat moss and sawdust. Sawdust is by far the best. I found that mice loved the coco peat, and I had problems with flies until I started using sawdust. I’ve discovered it’s best to keep as much liquid as possible out of the bucket, so I have a separate urinal. We have no code outside of the city limits here, so we didn’t encounter an inspection problem. — Michael Bandeko

We add a few scoops of coffee grounds to our coir shavings and lime. Flies hate it, and it adds an earthy smell. — Beverly Jones Miller

We use a composting toilet at home as a backup for bad weather. We’re planning on using it exclusively soon, as well as installing a greywater recycling system. Water conservation is a priority, and our city charges way too much for sewage. We also have a composting toilet in our RV to save water. — James Bill Riley
