The Sun Frost Human Humus Machine! I'm very excited about this humanure composter!

Larry Schlussler PhD, Sun Frost, PO Box 1101, Arcata, CA ... Human Humus Machine


super inexpensive (no price is listed but he says email him, owner of Sun Frost. haha - shouldn't be over $300 (instead of $5000). There is a hand pump, and a mixer, and a grate, and a vent and fan and the toilet seat. And then I buy 2 barrels, 55 gallon, plastic.  I could actually scrounge up those parts on my own....
The grate in the bottom of the composting chamber allows liquid to drain to the bottom of the composter. This liquid is incorporated into the compost pile by adding dry material to the composter, such as dry grass or wood shavings, and them pumping the liquid to the top of the pile. The composters are typically filled after about 1400 uses.
  incorporates a highly efficient and easy-to-use stainless steel mixer. Each time the composting toilet is used, instead of flushing, the mixer is rotated several times and the newly deposited contents are buried in the soil-like material in the composter. The mixer is conveniently stored inside the composting toilet.

 The Human Humus Machine is a batch-type CT. After the drum is full, the contents of the drum are allowed to sit for a number of months to complete the composting process. In non-batch type composters, newly deposited material can contaminate compost ready to be removed.

Into the drums are placed the insulated plastic lining provided and one of the drums put into use with the toilet seat lid. A pump is provided to draw out liquid end product from below a grate at the bottom of the tank, and recycle the liquid onto the pile after adding bulking material.
There is a vent pipe to add to a venting system (AC or DC) for aeration and odour control. An inbuilt mixing tool is also provided to mix the contents for faster composting. When full the tank is replaced with a new tank and the full tank, now composting, has a location for a venting pipe to help the composting process. 

I am not sure the County Planners would allow the Human Humanure Machine though - they don't understand composting I think. haha. I mean it is tricky to have the proper moisture and oxygen - and that's why a Ph.D. study by Geoffrey Hill in British Columbia proved that the NSF-certified humanure composters all failed in the parks, etc. So that is the original Clivus Multrum composter from Sweden and sold out of Massachusetts.
 
The Arcata engineer has realized the problem - too much surface area cools down the compost too much! That was my main concern also - so Sweden's [Clivus Multrum] argument though is just let it "mulder," or do a cool long term composting over two to four years. The national park system was probably not able to do a long term composting since their volume and use rate was too high...Just because the compost was failing when Geoffrey Hill tested it doesn't mean it wouldn't work eventually.

Hi Kevin Cunningham? I saw the promo review quote on the Sun Frost website. I have emailed Sun Frost as I am very excited to use this for a "year round composting" system in northern Minnesota. Do you have your Human Humus Machine set up inside or in a privy - what is holding the barrels? I am in a cold climate so I would need it to be heated indoors. I am wondering if you could send a photo or two? haha.
All the best,
