About the Recirculating Toilet and Its Use


A recirculating toilet is a waste containment system consisting of a water storage tank mixed with chemicals used for multiple flushing functions.

This compact system combines chemicals and water to neutralize waste bacteria such as coliform. In having so, it functions similarly to a chemical toilet process that eliminates contamination and odor.

The recirculating toilet chemicals include dye and biocides for the breakdown process. It also contains surfactants and fragrances to handle the smell.

What is a recirculating toilet’s primary use?


A recirculating toilet breaks down effluent using only chemicals and water. It also works to recirculate the liquid for future flushes, making it ideal for travel.

It occupies only a tiny space, allowing it to be completely operational without external plumbing and sewer connection.

With portability as a primary feature, it finds great application as an RV toilet, boat toilet, aircraft toilet, or as an option among available camper toilets.



  • High Ph – Recirculating toilets are alkaline, preventing anaerobic bacteria growth and limiting contamination.
  • Portability – Due to their convenient use for remote or outdoor occasions, they are ideal to be used or rented for long or short periods.
  • Being frequently cleaned, they are best for festivals, concerts, work sites, andopen-airr or off-grid locations. Its minimal water usealso makes it very eco-friendlyl.



  • Waste breakdown – Older models address this by adding a macerator, a mechanism that dissolves solids to the liquid, preventing drain clogging. Use of siphon to separate solids and liquids into different compartments also allows synching of waste processing and bacteria removal, just like in boat toilets.
  • Contamination – A filter mechanism is added beneath the flushing liquid to destroy bacteria. Adding more bactericide above the standard amount also fixes this.
  • Toilet tank gets easily filled – Tank filling takes only several days. Finding a sewer system more frequently means disposing of waste can be an inconvenient task compared with other toilet systems.

Overall, a recirculating toilet’s advantage for great functionality in off-grid locations makes it a very desirable system for RVs.
