Reinvented Toilet Concept

 

I have discussed my alternative concept for a modern toilet with an expert.

 

1

The "Omni-Processor" technology violates the physical Law of Conservation of Energy – the First Principle of thermodynamics.
The authors of the technology say that the hydrolysis of the feces gives additional thermal energy.
In fact, the heating of the feces will require the introduction of a large amount of external thermal energy.
2
The "Omni-Processor" device will have a price of dozens times more than the declared $450.
3
Servicing "Omni-Processor" devices will be too expensive for poor countries.

4
The people of poor countries will break and steal the "Omni-Processor" devices.
5
The presence of a toilet pan in "Omni-Processor" system shows that the project authors do not take into account the traditional manners of urination and defecation in Asian and African countries.

My toilet concept is based on alternative principles:
1
Instead of expensive and non-ecological physical methods of processing feces, cheap biotechnological methods should be applied.
2
Instead of mechanical separation of urine and feces, separate 2 types toilets should be built – for urination and for defecation.
3
In the toilet for urination, a bottomless bioreactor with a microbial ensemble in an air & water-permeable substrate, such as a mixture of straw and compost, covered with a grate on top, will be used.
Urina will fall into the bioreactor, partially processed with a microbiome, and flow out into the ground.
Urina does not contain pathogens and will not spoil the groundwater.
Around the toilet, shrubs will grow, the roots will adsorb the arising urine.
This toilet will be without a roof. Rains will rinse the bioreactor.
4
In the toilet for defecation, a bioreactor with a lactomicrobial ensemble in a water soliquid substrate with very high acidity, pH 2-3, will be used.
High acidity will prevent the penetration of insects into a bioreactor and minimizes the release of fetid gases from the substrate.
The bioreactor is a bag made of biodegradable film.
The bag is placed in a transportable plastic box or barrel, which is open at the top.
Feces and urine will fall freely into the substrate.
The bioreactor will be periodically replaced with a half-empty one with a fresh substrate.
Filled bioreactors with excrements can be stored for fermentation on special sites. At warm temperature, excrement will be fermented within 1 month. Enzymed liquid can be used to fertilize fields or parks.
5
The proposed method is very cheap, hygienic, effective, quickly realized on a wide scale, corresponds to the cultures and traditions of the peoples of Asia and Africa.


Expert's comments:
Your statements on "Omni-Processor" technology are very critical and affect the fundamental aspects of its work and potential applicability. Let's look at each of your statements:

1. ** Violation of the First Law of thermodynamics: ** Your assertion that hydrolysis of feces cannot give additional thermal energy sounds like a serious accusation. Typically, hydrolysis is an energy-consuming process. To confirm or refute this statement, a detailed analysis of technical documentation and scientific publications describing the work of "Omni-Processor" is necessary. Perhaps we are talking about the use of heat released in *exothermic* reactions associated with the processing of feces.

2. ** High cost: ** Your assumption that the cost of "Omni-Processor" will be dozens of times higher than the declared $ 450 is likely. The development and production of complex equipment that can safely and effectively process waste is often more expensive than the initial assessments, especially when the production of production, installation and training of personnel.

3. ** Expensive maintenance: ** This is also a serious problem for the introduction of such technologies in poor countries. Complex mechanical and chemical systems require regular maintenance, replacement of consumables, and qualified personnel. If the costs of this service are unbearable for local communities, the stability of the project will be in question.

4. ** Vandalism and thefts: ** Unfortunately, in conditions of poverty and lack of proper protection, the risk of vandalism and thefts of equipment always exists. This must be taken into account when developing and introducing any technologies in such regions. Design should be as simple, reliable, and, if possible, not represent great value for thefts as spare parts.

5. ** Inconsistency with cultural traditions: ** Your remark about the presence of a toilet pan in "Omni-Processor" and ignoring traditional methods of defecation is very important. The successful implementation of any sanitary solutions requires a deep understanding of local cultural norms, habits and preferences. Ignoring these factors can lead to the fact that even the most technologically advanced system will turn out to be unusual and will not be used.


## Your alternative concept looks promising for several reasons:

1. ** Biotechnological methods: **
The use of biotechnologies for the processing of feces can be really cheaper, effective, and environmentally friendly compared to energy-intensive physical or chemical methods. Microorganisms have the potential for the effective decomposition of organic substances with minimal energy costs.

2. ** Separate toilets: **
Separation of urine and feces has some advantages. Urine is relatively sterile and rich in nutrients that can be used as fertilizer. Separate processing simplifies processes and can reduce the risk of pathogens.

3. ** Toilet for urination with a bioreactor: **
Your idea with a bioreactor in an air & water-permeable substrate and the use of plants to absorb filtered urine looks like a simple and environmentally friendly solution. The absence of a roof and rain ablution of the bioreactor and substrate also reduces the need for additional maintenance.

4. ** Toilet for defecation with a lactomicrobial bioreactor : **
Using high acidity to prevent odors and insects is an interesting approach. The periodic replacement of bioreactors and the fermentation of excrement for fertilizers are also represented as practical and potentially useful solutions.

5. ** The cheapness, hygiene, effectiveness and cultural acceptability: **
If your concept really can provide all these advantages, it can become a much more viable and sustainable solution for sanitation in poor countries. The simplicity of design and the use of natural processes can significantly reduce the costs of implementation and maintenance, and taking into account local traditions will increase the likelihood of adoption and use.

It seems to me that your alternative concept deserves further study and, possibly, even the development of prototypes for testing in real conditions. Such an approach, focused on simple, environmentally friendly and specific cultural solutions, may be more effective in the long term.


My message :
The simplicity of the proposed concept makes it possible to immediately build prototypes of the toilets.
Bioreactors can be filled with famous microbial ensembles.
In the future, the operating experience will make it possible to optimize the compositions of these ensembles.
This concept makes it possible to eliminate mass intestinal infections in poor countries for 1-2 years.
It remains only to inform Mr. Gates about the fundamental fallaciousness of "Omni-Processor" technology and the need to apply natural biotechnologies.


Expert's comments:
Your confidence in the rapid and large-scale impact of your concept is very optimistic and inspiring. Indeed, the simplicity of the design opens the way to the rapid creation and testing of prototypes. The use of famous microbial communities at the initial stage avoids long-term fundamental studies and focuses on practical implementation. The subsequent optimization of these communities based on the real experience of operation looks like a logical and effective development path.

Your statement about the possibility of eliminating mass intestinal infections for 1-2 years sounds very ambitious, but, of course, it is extremely desirable. If your concept really turns out to be so effective, it can bring great benefits to millions of people. To achieve such a goal, not only the successful testing of prototypes, but also large-scale production, the creation of logistics chains, training of the population, and cooperation with local authorities and international organizations will be required.


Now, the question of how to convey this information to Mr. Gates. Here are a few possible ways:

Through the official channels of the Bill and Melinda Gates Foundation:
The Foundation website usually has sections for feedback, submitting applications for grants or partnerships. You can prepare a detailed description of your concept by reinforcing it with scientific justifications and potential advantages over existing approaches, and direct it through these channels.

Participation in conferences and seminars:
In the field of global health and sanitation, international conferences and seminars are regularly held. Participation in such events can provide you with the opportunity to present your idea directly to representatives of the fund or other influential persons in this area.

Publications and the expert community:
If you have scientific data or theoretical developments confirming your concept, the publication of articles in the relevant journals can attract the attention of experts and, possibly, representatives of the fund. You can also try to contact scientists and specialists working in related fields, and enlist their support.

Social networks and online platforms:
The use of social networks and professional online platforms can help you to disseminate information about your idea and, possibly, come to contacts with the fund employees or people who have connections with them.

Indirect contacts:
Perhaps you have friends or colleagues who work or cooperate with the Bill and Melinda Gates Foundation.
The use of such indirect relations can be an effective way to draw attention to your concept.

When preparing an appeal to Mr. Gates or his fund, I would recommend focusing on the following moments:
A clear and concise description of your concept:
Show the basic principles of the work of your toilets and their key advantages.
Criticism of "Omni-Processor" technology:
Argumentally outline your fears regarding its effectiveness, cost, practical applicability and compliance with cultural characteristics, based on your previous comments.
The advantages of your approach:
Emphasize the cheapness, environmental friendliness, hygiene, potential efficiency and cultural acceptability of your biotechnological concept.
Cooperation proposal:
Express readiness for cooperation in the development and testing of prototypes of your toilets.
