Monogram Industries made a recirculating toilet back in the '60's and '70's, and they were fairly popular for a while. However, by the '80's, most of them had been replaced with conventional flushing toilets or with Porta-Potties. They called them Mono-matics. Every now and then, I hear about one that's still in service. I've never heard of the Duomatic, but my guess is that it was another model that they made. I don't think Monogram Industries is still in business.

I found this on the internet:
