A lot of folk cringe at the thought of using composted human waste for growing food. Little do they know that all the sludge from municipal sewage plants ends up being sold as fertilizer for food production.
I've looked into commercial composting toilets and planned to purchase one when I relocate into my retirement property. The unit shown in the video definitely has plusses since it has no moving or electrical parts. The only thing I would add is a low volume fan to the venting pipe so that there was absolutely no possibility to have smells infiltrate into the house.
Thank you so much for sharing that video! I have been interested in doing a simple composting toilet for a while. The video helped me understand so much about them and what happens "afterwards".
I thought I would throw this information in the mix for conversation's sake. "Just because you can doesn't mean you should." I wonder how she checks for being in compliance with the regulations that protect the public. I know that sewage sludge is sold by the treatment plants, but I have seen more and more restrictions on the use of it for use in growing food in back yards. I know before I post this that there wil be those who "poo-poo" these rules. I just had to say that.
There are a lot of diseases that can be spread this way. I know I would never use it in my garden. I don't use animal manure either.
I'm glad I'm not her neighbor...
Is she waiting the 20 or 14 month period identified below before harvesting crops? It doesn't sound like it.
Here we go:
Pathogen reduction
Federal and state regulations require the reduction of potential disease-causing microrganisms, called pathogens (e.g., viruses, bacteria and parasitic worms) and vector (e.g., rodents, birds, insects that can transport pathogens away from the land application site) attraction properties. Biosolids intended for land application are normally treated by chemical or biological processes that greatly reduce the number of pathogens and odor potential in sewage sludge. Two levels of pathogen reduction, Class A and Class B, are specified in the regulations.
The goal of Class A requirements is to reduce the pathogens (including Salmonella sp., bacteria, enteric viruses, and viable helminth ova) to below detectable levels. Class A biosolids can be land applied without any pathogen-related site restrictions. Processes to further reduce pathogens (PFRP) treatment, such as those involving high temperature, high pH with alkaline addition, drying, and composting, or their equivalent are most commonly used to demonstrate that biosolids meet Class A requirements.
The goal of Class B requirements is to ensure that pathogens have been reduced to levels that are unlikely to cause a threat to public health and the environment under specified use conditions. Processes to significantly reduce pathogens (PSRP), such as digestion, drying, heating, and high pH, or their equivalent are most commonly used to demonstrate that biosolids meet Class B requirements.
Because Class B biosolids contain some pathogens, certain site restrictions are required. These are imposed to minimize the potential for human and animal contact with the biosolids until environmental factors (temperature, moisture, light, microbial competition) reduce the pathogens to below detectable levels (Table 2). The site restriction requirements in combination with Class B treatment are expected to provide a level of protection equivalent to Class A treatment. All biosolids that are land applied must, at a minimum, meet Class B pathogen reduction standards.
Table 2. Class B biosolids application land use restrictions (VDH, 1997).
Root crops, where biosolids remain on land surface:
> 4 mos. prior to soil incorporation
Harvest 20 months after application
< 4 mos. prior to soil incorporation
Harvest 38 months after application
Food crops that touch biosolids or soil
Harvest 14 months after biosolids application
Other food, feed or fiber crops
Harvest 30 days after application
Turf
Harvest 1 year after application when the turf is placed on land with high potential for public exposure
Just a thought, but you might want to wander around their website before getting too upset. http://greywateraction.org/cat/image-tags/los-angeles
Historically, poo was allowed to return to dirt, as is its natural process, but today we make toxic sludge.
Something is wrong with that picture.
Might want to rethink planting in dirt at all if you are concerned about what it used to be
Yea comercial farms use human poo on there farms lol. I wouldnt do it because i wouldnt want tO contaminate the soil. Humans ingest so much poisons that the soil would eventually become poison. All the people taking pills or eating fake processed chemicals or medicines lol
A septic tank is still very great because it contains the waste and still allows water back into the earth and still maintaining health. This toilets great if there wasnt hepatitis carriers and ecoli carriers in peoples bowels.
Interesting anyways, big farms dO use human waste from what i heard lol
