Hello Lilbet.
Thanks for asking a very useful and practical question.
Here in the UK there are at least two suppliers that I know of that issue complimentary wipes and disposal bags with each order. These suppliers are Coloplast and Fittleworth. I am not sure if one or both companies are in the USA, or if they offer the same complementary items over there, but it might be worth enquiring, as these companies boast that they will supply stoma goods to almost anywhere around the world (for when we are on holiday).
It might also be worth noting that these disposal bags are (almost) identical to the bags we can buy that are used for picking up dog-pooh - except they are a little bit stronger and they are scented.
When I was first incontinent our local council offered to supply me with a 'clinical waste' disposal box, which they would collect regularly. However, when I deduced that the content of these was being sent with the rest of the waste to landfill, I thought it was a waste of time and resources to have a separate collection service, and I have subsequently disposed of the waste in the appropriate landfill bin.
I have often wondered why some enterprising manufacturer hasn't switched from plastic by now, and developed more suitable devices that can be disposed of by incineration, or biofuel generation.
Just a thought!
Best wishes
Bill
