Chemical toilet in an airtight box

[DeeJay]

I bought a trianglar aluminium drawbar box & have done a damn fine job of dust sealing it.
But is now near airtight. Would it be wise to store the portaloo in it? would the methane produced possibly bulge the box ?
I have looked thru the interweb but no direct answers there. There is some discussion that the chemicals negate the gas producing process.
I can drill a large hole & fit a filter but dont want to if I don't have to...

Pressure valve?

Near airtight??

If it’s not 100% than you’ll be right.

The portaloo is sealed anyway so don’t see why it would matter.

Actually.....yes, ours is sealed and never lets smells out...until you open the trap door.

Yeah, I’ve had a near full one on the back of the car with me - doesn’t smell at all so assume it must be airtight itself.

Yep they are sealed = on a hot day my portapottie blows up like a balloon - was worried with it in the back of the car - in future on hot days its not going in the car - just in case.

I have got one on my boat and even on the roughest of days it never spills/leaks or smells, Unfortunately I still have to empty it and it can be a bit pongy then.
