Firstly, as a matter of relevance, toilet paper is more important than research paper
Research papers I have written many, bog paper I have been short of many times and can testify that in most real world episodes bog paper is far more important than research paper, although it must be said that many would consider my research papers to fulfil a dual role.
The Thetford 335 portaloo is a perfect fit for a Cali. It nestles comfortably between lower bed laid flat and passenger seat. It is fairly stable in travel when kept in the accommodation area. With the rear bed board on it's highest level it fits in snugly in the boot of an SE/ocean.
However it is bulky, gets in the way and when in the wilds and wild camping it can be problematic to dispose of contents.It can also, with both tanks near full, be very heavy to move around.
The pop-a -loo is a non-starter. It has to be erected outside, takes time to put up, allegedly takes 500 times more to take down, and for me is not compatible with a "park up tonight - move on tomorrow" lifestyle.
The bog-in-a-bag is, comparatively, hugely space-economical . Basically it is a foldable tripod seat with a removable centre-piece that then accommodates a poly bag in the void, the poly bags, partially filled with absorbent crystal, taking up minimal room in a pre-use storage state.
For me, someone who frequently collects my dog waste in a poly bag, who has existed outdoors in most unprim and unproper circumstances, collecting my own waste in a poly bag is not problematic. However for many it seems that the simple function of tying a knot in ones own bagged waste is a step too far, and therefore in those circumstances the portaloo is indispensable.
Given that personal attitude towards collecting personal waste in an easily sealed and leakproof container is not a problem then certainly a bog-in-a-bag concept is both space-saving and adds an element of extra flexibility in both storage and disposal of human waste product.
Therefore we now approach the subject spectrum of economics, hygiene and practicality.
Economically BIAB, to use my newly-invented acronym, is expensive. The tripod seat is £20 and infinitely durable but the disposable bags are uneconomic and unjustifiable financially, Many consider the replacement cost of proprietary bags to be what is technically known as a rip-off.
Whilst the problem of alternative sourcing of a collecting bag is easily overcome with many economical and eco-friendly alternatives being available, the same cannot be said of the absorbency material. However after limited testing of a range of disposable absorbency materials what I can say is:
Cat litter fails miserably. Just talk to my neighbourhood cats. Absorbency is pathetic, odour control miserable, weight when used almost beyond the limits of an all-bio bag and horribly heavy to carry even in unused state.
The daily mail, whilst often taking the P*** out of everyone, is useless at absorbing it:
Various forms of "super absorbent" kitchen roll are great at mopping up wine stains off the carpet but fairly useless at mopping up other forms of droplets that one would wish not even to arrive on the carpet.
Disposable absorbent hygiene products all have shortcomings: For me the Damascene moment came when I switched from disposable nappies to more eco-friendly reusable nappies with compostable liners. (For my grandchildren, not for me
)...
Disposable, eco-friendly, compostable and hugely absorbent liners are a far more economical alternative to powder-based pre-loaded bags (less than 50% of cost) but have just one negative: The size of the liner. However being lightweight a standard pack of 32 can be carried on top of almost anything and for the purpose intended are durable enough to be squashed and crushed into the tiniest of spaces.
In terms of emergency application: Pre-planning is essential. On long journeys the convenience of a 335 is great. Pull in, get in the back, lift the lid, fulfil the necessity of the moment, carry on driving.
With BIAB preplanning is essential: Ensure sufficient quantities of liners and bags are in strategic reach, for me ideally that is on the back of the base support of the passenger seat. Ensure the velcro tabs of the bag enclosure for the seat are undone. Reaction times in those circumstances for practical purposes can almost equal those of utilisation of a 335.
For overnight comfort the same applies. The BIAB is unfolded and placed in strategic position, the bags and absorbing material resting on the base of the passenger seat.
In terms of hygiene: I see no greater problem to my waste products being carried slopping around in a formaldehyde chemical weapons chamber then being captured in an inert, eco-friendly substance that can be double-wrapped in extreme situations and with both hands and wrapping then wiped with a disposable and eco-friendly anti-bacterial wet wipe.
The BIAB, when in use, is less stable, so more care must be taken not to tip tripod over spilling contents everywhere, It goes without saying that this caution is especially prudent when using the BIAB after consumption of some fluids that also have a diuretic effect. Situations of potentially urgent and clumsy application need extra care.
In summary: The BIAB is cheaper in terms of capital outlay, offers more in flexibility of disposal of waste material, needs more planning on application, is fundamentally more space efficient but requires in some individual cases adaptation of personal preferences towards bodily functional issues.
It will be, after the current year of testing, my preferred method.
