Our paper is great for alternative toilets, including composting, and sensitive systems like septic tanks! Our products have been tested for disintegration and “flushability”, and shouldn’t cause any adverse effects from normal use (don’t stick a whole roll down at once).
If you have a particularly sensitive septic system, we’d suggest asking your manufacturer whether any restrictions apply. For example, we know that some play nicer with 2-ply than with 3-ply, but this varies between systems.
If you're looking for the toilet roll that will break down the quickest, that'll be our recycled - which breaks down under 10 seconds (that's also the same for RV dispersion standards!).
