Tanks can be partially buried
Trouble-Free Design
Only two moving parts: the fan and the toilet seat.
All CTS composting toilets are designed for odorless operation using aerobic decomposition, commonly called composting. The digester tank has a sloping floor upon which the accumulated waste, toilet paper, tissues, and other organic materials form the composition mass. Baffle walls and air channels provide an oxygen-rich environment for the ever present microorganisms that thoroughly digest and decompose the accumulating organic materials. This aerobic decomposition generates heat, and heat rises naturally, carrying moisture-laden air and carbon dioxide up and out the vent stack. There is no methane gas produced. This natural air flow is assisted by either an AC or DC fan to create a vacuum inside the digester tank. When the toilet seat is opened, air and gases are drawn down through the toilet seat and up the vent stack, leaving the restroom odorless. As the digesting waste slowly moves down the sloping floor, up to 90% of its volume is eliminated by decomposition and evaporation. The end product is aerated fertile organic humus, similar to garden soil, with no objectionable odor and easily removed through the access door.
