Technical designs that will incorporate vermicomposting at the exit phase of the UDDT systems

Note by moderator: More information about Clint's work is also available in these threads: +++++++++

Dear Forum Members,

We have utilized vermiculture in our composting tanks for over 40 years with tremendous success.

We utilize redworms and a very small white worm, which we acquired from sludge at the Fairbanks, AK sewage treatment plant.

If you are going to compost human toilet resources it is highly suggested that you add additional kitchen food scraps to dilute the composting mass. Also, you need to add the carbon source as we do with pine bedding.

If all pit latrines or any other location that people use to defecate just added the carbon source each time of use they would add a layer of air channels for the worms and the organisms. Then the resources can compost effectively with just the addition of oxygen.

Worms are the intestines of the universe and their function is to convert the resources to worm casings for fertilizer. The compost tea is extremely valuable and can be utilized directly on non-edible crops as liquid fertilizer.

Our vermiculture even worked in Alaska.

Decentralization, onsite utilizing composting tanks works with no need for water or infrastructure.

Re: Composting system - AlasCan and Equaris Corporation (USA)

Dear all,

I feel the need to give you a bit of history as to why my written comments may seem to be a bit on the controversial side concerning my personal experiences, observations and conclusions of governmental regulators, academics, licensed professionals and organized teams participating in the conventional wastewater treatment industry.

The following are just a few examples of the historical resistance from those entities to the life sustaining accomplishments made by the Human Endeavors’ Foundation.

While constructing geodesic domes in Winter Park, Colorado, in the early 1970's, I had absolutely no knowledge of the toilet business, but soon became aware of the difficulties of installing septic systems.

I read an article in Organic Gardening and Farming about the curious invention and operation of the Clivus Multrum composting toilet and Abby Rockefeller’s purchase of the North American distribution rights.
I became fascinated with the potential of reducing water consumption, pollution and producing a positive product. I quickly became a distributor by purchasing and installing my first system to use and learn.

The hippie generation was attempting to make a 'green' difference and I sold and installed systems in the West for 12 years. Hippies actually had very little money, so when my sister and brother-in-law sent me a one-way airplane ticket to Healy in Alaska's Interior, I joined them.

The geodesic dome knowledge kept me afloat, but I was offered another job in 1983, that of installing a couple of Multrums for the US Army National Guard in Selawik and another at Elmendorf Air Force Base in Anchorage.

The Guard was impressed with my work and knowledge and asked me to design and manufacture my own composter in 1984. From that contract, I manufactured and installed over 50 of my large composting tanks in remote Eskimo village US Army National Guard armories from Point Hope to Dillingham.

Because my systems worked, the native communities accepted me well; I became a contractor for NANA (North American Native Association) in Kotzebue and worked with them installing my systems in their headquarters and at their spirit camp, Sivinivik.

Sivinivik was the only remote location where the elders could teach their youth their own native customs and their own language without being threatened by the new educational system forcing them to abandon their language to speak English. I felt very honored to be accepted by them and allowed to install my technologies.

My proven systems had received a 1988 US Department of Energy National Award for "Energy Innovations" for the sustainable green geodesic dome I had designed and constructed. It contained my composting and greywater systems along with solar heating. By 1988, I had installed the most northerly ground source heat pump in the world, and for it, I received an Alaska Legislative Award for my Environmental Achievements.

The then Governor Walter Hickel provided me with a $15,000 contract to put one of my own entire systems in a native Eskimo’s home as a volunteer native Alaskan family. Lester and Grace Hadley with four children in Buckland, AK near Kotzebue offered but explained that if it did not work, I would no longer be welcome in their home.

It worked, they were delighted. NANA's native elders were impressed that a white person had finally come around to actually help them instead of use them.

I thought the ice had finally been broken until I read reports from the USPHS and ADEC that my system was not only malfunctioning but was also a public health threat.

Of course, the report was fictitious, but by eliminating my company, AlasCan as competition, and me it allowed the Corp of Engineers to drain another $5 million to study other applications on wastewater that would funnel even more funds to them when they did the job.

Today, Buckland, a community of 84 residences, one school, a store and a Town Hall is under construction with $50 million taxpayer dollars allotted for the installation of a piped system in Buckland that, like
the other remote village systems, has a failure rate of 95%. The
natives cannot afford to operate it.

Over $6 billion dollars of US taxpayer money has been spent at similar Alaska villages and 90% of that money is staying in the hands of those degreed, regulators, engineers and pipe manufacturers in Anchorage, Juneau and Seattle. (US Office of Technical Assessment, 1990's)

In 1995, when I moved back to my home state, Minnesota Rule 7080, had been written with the verbiage covering Individual Sewage Treatment Systems. This didn't interfere with my business; however, after several attempts to work with the Minnesota Pollution Control Agency
(MPCA) and their degreed soil scientists, 7080 was over time rewritten to now singularly and solely dictating Individual Subsurface Sewage Treatment Systems and as an end result, eliminate me, non-subsurface discharging systems, as competition.

MN Statute 462.357 states that the only wastewater technologies legally allowed (taxpayer-funded) are ONLY piped water/sewer and the restrictions provided by MN Rule 7080 for strictly sub-surface DISCHARGING/DISPOSAL SYSTEMS.

For the past ten years, submittals have been made to city engineers with the financial and environmental advantages of “Separation”
technologies only to have those cost estimates purposely distorted and rebuffed by those consulting engineers to the city councils while governmental protectionism is being provided by the taxpayer funded engineering oversight boards controlling/not disclosing any, including damaging evidence to the public without a court order.

Another water main break in downtown Minneapolis this morning should serve to promote the logic of my systems. As we, all know; the breaks we see now are just the tip of the deteriorating pipe system’s iceberg. In fact, wastewater treatment has always been maintained by those with vested interests in the status quo. Whether it is finances or job security influencing decisions, the concerns of the taxpayer and the environment always take second-place.

With over 45 years of attempting to work with the regulatory and academic/professional communities, having patents in hand, proof and accolades from newspaper articles, TV and the native people of Alaska, Human Endeavors’ knowledge and capabilities in addressing and improving human sanitation and environmental water quality is unmatched by any existing or even conceptualized centralized methodologies.

To Bill and Melinda Gates, the Zuckerbergs and all the rest of you who want to get something going instead of just reading about what if!
Stop analyzing and just do it with what we know and have proven to work! It is time to implement sustainable “Separation and Recycling”
technologies now!

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

Good morning,

I am pleased to inform you that composting of organics, as well as human resources, has been accomplished in a variety of small to large contained vessels for decades.

As I stated earlier, Clivus Multrum, invented by Sweden's Mr. Richart Lindstrom back in the 1940's incorporated baffles and air channels in a fiberglass box with a sloping floor, which is still being sold worldwide today. His initial design was good but the air channels obstructed the composting mass to settle effectively and the sloping floor idea for glacial removal does not work very well.

My design, which I also copied from large solid organic waste composters, utilizes baffles on both ends and a false floor perforated sheet of plastic, 1/4" thick suspended off the floor by at least 6" for the air to be forced, or naturally vented with the chimney effect with a large vent, to provide the needed oxygen to the aerobic organisms and redworms. In my automated version, I have added agitators on the top of the composting mass to stir the fresh resources and spread them out evenly without a pile growing. I also add pine bedding as the carbon source to add air space in the pile of feces pudding for added ventilation.

My end result, because I feed from the top and remove from the bottom is pure rich black soil with absolutely no odor and millions of redworms.

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

Dear H-A,

I am on the road in Costa Rica so I do not have a drawing on my computer to send you at the moment.

If possible you might be able to check the US Patent office and search Apparatus for composting, but because that patent is over 20 years old it may have been removed.

Also google Clint Elston, AlasCan, Inc. and Equaris Corporation and there may be some drawings somewhere.

To explain simply:
A horizontal double-walled box split in half for ease in transportation, two baffles at each end to provide for air circulation via the raised false floor made out of perforated plastic sheet to support the composting mass and to allow the VALUABLE compost tea, to include URINE, TO BE PUMPED INTO A RESERVIOR FOR REMOVAL AS LIQUID FERTILIZER.

There are two motor driven gear motors to drive 2 rpm plastic agitators to spread the fresh fecal and URINE resources and three plastic augers on the bottom, above the perforated sheet to remove the finished vermiculture/compost. A spa fan draws air in and out of the air channeled box and vents 95% of the solids and liquid URINE into the atmosphere as ODORLESS carbon dioxide and water vapor.

This automated system can be totally passive because of the air channeled design and can easily operate for much less than $.05 per day.

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

Clint's patent is here .

There are a few pictures available of the system:











And a bit of information here .

Clint, the information provided on this website described a reduction in suspended solids of 50 - 80% and a reduction in biological oxygen demand of 78 - 93%. Could you provide absolute quantities per litre of effluent output?

cheers
Dean

Re: [SuSanA forum] Composting system by Human Endeavors (USA and in future Costa Rica) (Composting processes)

Dear Dean,

I cannot thank you enough for digging up this information and sending it.

I do have a total report done by Olmsted County, MN, ChesterWoods Park, which I have with me in paper copy and I will review it and send you your requested information tomorrow.

Again, thank you so much!

Re: [SuSanA forum] Composting system by Human Endeavors (USA and in future Costa Rica) (Composting processes)

Dear Dean and other interested parties,

I am trying to answer Dean's question about flow and I do not see that the flow was ever monitored in this project.

I will say this that the residence tested had two occupants, which would equate to approximately between 40% less than 75 - 100 gallons of effluent per day because of the ultra-ultra low flushing Zealand toilets being separated to the composting tank.

Inserted is another combination of information I put together, which may help.

Clint

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

Dear Dean,

I again want to thank you for finding information that I did not even know where it was.

I also submitted additional information, which I hope will answer your question about flow.

The answer is that in Minnesota the average normal usage is 75 gallons of water per person per day. With my system, because I utilize Sealand toilets and separate the toilet flow from the grey water the flow would be 40% less.

The testing location was the caretaker of the Chester Woods Park's home with just he and his wife with occasional visitors but they did not monitor the flow.

The testing was done in 1998 and I have dramatically improved my grey water system since then. The incoming water quality was also full of iron bacteria so seating it only decreased the potential improvement of the treated grey water so that is probably why the body and toss were as high as tested.

As you can understand, since then I have been able to further treated grey water to drinking water qualities utilizing a great deal of ozone and reverse osmosis. Because I am recycling treated reverse osmosis grey water I have been able to document a 95% recovery of the grey water because all of the minerals are taken out in the first pass.

They did install a 40% less in size drainfield and only 10% of it ever saw any effluent because of the extreme high quality of the effluent, so no biomat ever built up, meaning that the leachfield would have lasted forever.

If I can answer and/or clarify any questions you may have just ask.

Thank you again,

Clint

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

Dear Forum Members,

Hopefully, many of you have had a chance to view the drawings of, specifically, my composter, which details the agitators on the top of the composting mass and the augers on the bottom. The old design had air channels within the composting mass and now, in order to eliminate the compost hanging up on the air channels, I have incorporated the false suspended perforated floor.

I have now been able to view various YouTube videos of the Ecosan toilet building and the urine diversion and toilet squatting apparatus.

To begin with, I have a hard time understanding how flushing with ashes, lime or sawdust or whatever, can control the odor. In my experience, those additives thwart the original purpose of oxygenating the compost; which should be eliminating any methane/hydrogen sulfide production. Those additives only negate the ability of the aerobic organisms to breathe.

Also,in my experience, to even be able to contribute to composting of fecal mater and URINE you have to add a carbon source that is relatively larger in size than sawdust such as pine bedding to provide porosity. The material a hamster lives in. Ground up leaves, anything that is not a hardwood, cedar, redwood or something that is designed by Mother Nature to last longer under decomposition aerobically.

If I were asked to redesign the existing Ecosan toilets, I would provide an air circulation system instead of just building a vault, which is no more effective than the present outhouse design.

The idea of utilizing one chamber until it fills up and then switching to a second chamber tells me that the design and the addition of the suggested flushing ingredients are not providing an aerobic environment and that is why it does not decompose quickly leaving resulting odor. Capping off the used chamber and then going to the next chamber even reduces the capability of the oxygen to even get to the first used chamber.

I can appreciate the fact that the existing projects are attempting to advance local employment with the concrete toilet unit, utilizing the flushing plastic flapper. It makes more sense to promote permanent employment by engaging them in production of recycled polyethylene plastic tanks and ultra-ultra low flushing, low tech toilets, which can be duplicated and utilized in other villages instead of just another research project. At the same time, plastics, presently being discarded, could be reused.

Also, the idea that the homeowner is responsible for maintenance, which never works in advanced cultures as well as developing countries and then someone else has to remove, transport and then try to compost the feces again without designed, non-mechanical aeration, without urine only complicates the situation and adds additional requirements upon a society that is already burdened with trying to get water to just drink.

On the other end of the spectrum is the toilet design utilizing nanofiltration. I find it difficult to understand first that someone could dream up such a complex ineffectual solution and second, that someone else would finance it. The subject is far too vital to waste those funds on the academic who dreamed it up just to insure tenure.

A lot of you are probably going to be upset with my comments, but since I'm older, I've had the opportunity to learn from far more actual trial-and-error experiences over a lifetime.

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

You need to remember that a UDDT does not depend on the feces being decomposed. Heat and time will eliminate the pathogens and that is the main concern. The storage time is to allow the pathogens to die and eliminate the moisture. After 6 months it has become a vital ingredient to nurture the soil. The urine is sterile and can be used as a fertilizer within a week. It has the majority of nitrogen, phosphorous, and potassium required to grow crops. Instead of having dead, depleted soil you will have vibrant, nutritious soil with vital micro nutrients.

The UDDT is a simple devise that can be manufactured from local material in any part of the world and will continue to function indefinitely with only minor repair. Every 6 months the human fertilizer will be removed to help nourish the soil. The urine will be continuously used.
No plastics are required that have to be imported and have the potential of deteriorating and becoming an environmental hazard. The system is SIMPLE with no moving parts. That is so important when working in the developing countries.

As for age many of the people on this forum are your age or older. I was working in sanitation in the early 1970's.

Re: Composting system by Human Endeavors (USA and in future Costa Rica)

I would agree with Tore - these toilets usually work well if constructed and used properly.

The reason I have started to get interested in more wet forms of sanitation is that many people use water to clean themselves (rather than using toilet paper), and because in completely dry sanitation, low income people don't have the money to buy toilet paper.

There are UDDT toilets which offer basins for cleaning with water, but I have found that these are often misused, and water at the wrong place is a major course of odor and unhygienic conditions.
