Waste-holding tank products

You collect human waste when using Thetford’s cassette toilet or Porta Potti. Thetford’s specially formulated toilet additives support hygiene by suppressing odours, preventing gas build-up, and liquefying waste for easy discharge at a dedicated discharging station. Treating the waste inside the tank and keeping the waste-holding tank well-maintained is vital to avoid unhygienic situations, nasty smells, and even leakages.

How to apply waste-holding tank products

Before you start using your toilet or after you’ve emptied the waste-holding tank, it’s time to add an additive. If you’re using a liquid product, use the measuring cup located on the pour-out spout of your cassette and follow the instructions on the label. Make sure the bottom of your cassette is filled with water before you start adding the toilet additive. By following the instructions on our labels, you minimise the environmental impact.
