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.

"The composting toilet process creates a rich, fluffy compost similar to that from a well-maintained garden compost pile or the composted leaf litter from an old-growth forest."
