Bucket and chuck it is way better imo than portapotti. Keep pee separate if possible and use some dry material to absorb and cover after use. Then chuck into secure compost heap for min. 12 months. No smell is possible. Not going back to p p.

Alternatively you can also use wood pellet cat litter instead of a nappy :)

No bog in a bag?

Whats that plastic Bag ?? Be prepared :)

Hahaha! In other words , dump daily! Daily. How many uses per bag? Lol, (1). Your cassette toilet with chemicals in the holding tank can go a month or more. One month and have multiple users. By the way, where DO you dump your plastic bag? Gross!!
