Nassef, president of Nassef Engineering and Equipment Company, has developed a new way to dispose of RV waste that uses green technology to eliminate sewage from RVs.
The ThermalTreat Zero Liquid Discharge (ZLD) Sewage Elimination System uses a small gallons or less sized tanks, grinds up the solids, and then dissolves the solids in the liquid. It then pressurizes this liquid and injects it into the hot exhaust gas of the engine. Steam and negligible minerals which come from the food people eat leave with the hot exhaust gas. The system is small, lightweight and uses no chemicals. It produces no odors, liquid, or solids to handle.
"We believe that there is a growing desire for environmentally friendly energy recovery methods to handle sewage," said Nassef. "It is our belief that when this technology is offered and demonstrated, the demand for it will be overwhelming since it is more efficient, cost effective and green. The current markets are huge -- valued at several hundred million dollars per year -- and the international market is immeasurable."
The ZLD processing unit without the EQ tank is approximately 12-by-18-by-24 inches -- the size of a medium suitcase -- and weighs less than 100 pounds. Still, it can process approximately 300 gallons per day depending upon available heat simply using engine exhaust to treat and dispose of sewage with no liquid discharge.
Nassef predicts it will eliminate large holding tanks in RVs, thus giving designers more storage space for other needs, such as clean water or cargo. It also eliminates the problem of dumping sewage holding tanks when there are no convenient places to dump, he noted.
Advantages of the system include:
- No odors
- No liquid discharge
- Energy recovery
- Environmentally friendly
- Small/lightweight
- Operable worldwide
- Operable in all climates and harsh environments
- Quick start/stop or storage/use cycles
- Plug-and-play design for replacement or repair
- Potential water reuse
- No chemicals required
- No sludge to dispose

This sounds like the 1970s-era Thetford "Thermasan Waste Destruction System", which used tow vehicle exhaust to do the same thing at the rate of 2.5 gallons per hour. Nothing new here, except that using a 12.5 kw generator to incinerate sewage is hardly "green".
What happens if you stay parked in one place for a couple weeks. You aren't using the engine & you'd need to dispose of the waste!
Sounds like you would need to constantly run your rv engine to process up to 300 gallons of waste a day. How much gas or diesel would you burn up to do this? This hardly seems 'green' or cost effective.
My trailer does not have a generator or engine - trailers make up the majority of RVs so .....
What about travel trailers and 5th wheels, what do they do?
If you look at the picture, it seems to come with a 12.5 watt diesel generator.
what about my truck camper. truck campers have to slide on and off so how would you hook up the exhaust
Why couldn't an "Incinolet" incinerating toilet be adapted for RV use? They are specifically made for small spaces and can run on electricity or propane. Also, it ould not require using a storage bay.
I think they have an electric Incinolet that you can install in an RV right now. propane would be good for boon-docking...
What's so green about having to run a diesel generator to use this device? And what do you do if you're not moving?
The "GREEN" comes in, as the article stated, in the way of NOT having to dispose of and treat the sewage. Can you imagine how much energy and $$$ is used to treat sewage. It is one of the greatest expenses a city faces. We RVrs dump our tanks, and the treatment plant must deal with it. And there are a lot of Rvrs out there.
I have a composting toilet in my motor home. The composted waste can be spread out on the ground as fertilizer or put in trash bag and placed in the dumpster. I linked the black water tank with the grey water tank and have 103 gallons of gray water storage in my 33' motorhome
That looks like a great add-on to an RV. That will make pipe de-clogging a little more easier.
