Composting toilets provide off-grid homesteads or vacation cabins with a safe, odor-free waste processing system that yields extremely high-quality garden compost. They require little to no water or electricity (some units have electric fans).
We offer two basic styles of composting toilet systems: self-contained composting toilets, where everything is included in a single enclosure, and central composting toilet systems, where a large central composting chamber is fed from one or more toilets.
Composting toilets are not practical in some situations, like apartments and cold climates with little activity. Choosing a composting toilet with the right waste processing capacity and options for your intended use can be tricky business, so if you're at all unsure about your needs, call the Real Goods Tech Desk at 800-919-2400 and we'll lend our expertise.
Central composting toilet systems offer a more traditional-looking toilet in the bathroom that is connected to a central composting chamber, typically located in a basement or outside. These units can typically handle more waste than a self-contained composting toilet, and multiple toilets can be connected to the central composting chamber.
If you are unsure about your composting toilet needs, don't hesitate to call the Real Goods Tech Desk at 800-919-2400.
The simplest kind of off grid toilet is a self-contained composting toilet. These off grid toilets combine all the necessities – a place to sit, a composting chamber, and an evaporation tray – in a single enclosure. Self-contained composting toilet systems are installed directly in the bathroom (no plumbing required) and electric models can plug into a standard wall outlet. Another advantage of a self-contained composting toilet is that during winter in cold climates (when the composting microbes needs to be kept warm), heating the bathroom keeps both the toilet user and the compost chamber warm.
In central composting toilet systems, the composting chamber must also be kept warm, but is often installed in a basement away from the bathroom. If you are unsure about your composting toilet needs, don't hesitate to call the Real Goods Tech Desk at 800-919-2400.
With careful planning, you won't have any trouble with your composting toilet system's waste processing or compost production. But to kick-start your composting microbes or accelerate their production, try our composting toilet accessories, including starter mulch and microbe mix.
Also sold here are waterless (or dry-flush) toilets and conversion kits to convert a Sun-Mar Centrex 2000 or 3000 central composting toilet system from low-flush to waterless.
