I wish you the best, but having looked into these topics when I was interested in RVs a few years ago, I think there's no market for your proposal because the market is already well served by (at the higher end) composting and incinerating toilets, which are clearly more palatable, and, at the lower end, just putting kitty litter in a bucket with an optional toilet cover, which you can already do for nearly free. I think most people who really wanted a waterless toilet would already fall into one of those two camps (cheap and crummy or expensive and fancy) leaving little room for your product, which would be both more expensive than just putting kitty litter in a bucket, yet not really all that much more palatable, since you still have to dispose of the used material, which is really the essential "annoying" part that would make one want a fancier option. You are forced to figure out how to deliver enough value to be clearly better than shitting in a bucket, yet not much more expensive, to avoid competing with composting or incinerating toilets. I wonder if you actually might do better starting from a composting design and trying to improve it to make it more cost effective. Sorry for the pessimism, just some things to think about! Maybe there is a path through, wish you the best.
