It sounds awesome, but I am somewhat skeptical. The economics depends on the land price and the operating costs. Without high property prices, you do not need 24 hours processing time, and the increase of the operating cost is not justified. This can be a rationale why the process is not used widely (only economical around high population density cities).

My ultimate concern is about the feasibility of the organic decomposition. Other composting systems are already optimized by the managed temperature, moisture, and oxygen. The biological culture has a significant cost and irrational to apply 10 or 100 times more since only a part of the culture will thrive (the culture contains some species) in the given environment. This part will rise and double in each period, but it also needs to spread (mixing).

I would like to see how it works; it looks promising after my concerns eliminated.

Mr. Robert,

Thanks for answering. 

Agree with your questions.

Ontario Science Centre has a composting system that has been operating for years, and in 24 hours the organic matter (mostly cellulose and hemi-cellulose) is broken down to a point that you can't identify what it was.  If you toss in a whole pig (which they did, just to see how fats reacted), it wont be dirt in 24 hours.  It becomes 'soil' in a week.

The main reason this isn't done everywhere is the energy requirements.  45 days for very little energy input.  A small handful of days means grinding everything, blowing lots of air, and maintaining moisture balance = much higher energy input.

The degradation rate of your solids is the rate limiting step in the composting process and directly related to the surface area of the particles. You can reduce the particle size but then you loose the physicial structure for aeration. You can compensate for this by very advanced systems but this will increase the Capex and Opex of your process beyond reasonable costs. Practical large scale composting processes at acceptabel costst will take at least 2-3 weeks to produce comnpost with an acceptable stability. 

Thanks sir.

Not possible unless it is actually thermal degradation.

Temperature is considered a vital parameter for the decomposition of organic matter. More than 70% of lignocellulose substances are degraded by thermophilic microorganisms in a high-temperature period. To enhance organic matter decomposition, continuous high-temperature composting always desired. Diverse disposal processes using physicochemical and microbiological techniques are highly valued and widely used in composting to obtain thermophile temperature faster and for long-duration such as the addition of bulking agent, ventilation control, and use of microbial agent at the initial stage of composting.

So, if the composting process goes beyond the warming period and the composting temperature is raised from the beginning to a higher temperature, it is possible to realize the rapid degradation.

Answer for above mentioned questions:

Even though maturity parameters are met within the short time of 24 hours at higher temperature. The composting is a controlled process and has to undergo three major phases to obtain a stable and mature product. And the mature product is always obtained during long weeks period depending on the mass of the material. So, we can say a Stabilized compost can be obtained within 24 hours of controlled composting (Temperature, aeration, moisture, mixing).

In conclusion, it is feasible to improve the composting processing efficiency by rapid thermophilic composting. However, this stable product should undergo of few days maturation phase to be mature organic fertilizer.

However, The obtained stable product could be applied to the soil to reduce the use of inorganic fertilizer. However, the this product should not recommended to be used as nursery substrates, a reasonable amount and the proper application method should be selected based on the soil and crop type.

However, due to the high energy consumption cost caused by external heating system and other controlling parameters, most of you are not in favor of this technique, but I think this a promising way to utilize high amount organic waste if we focus on the methods to reduce the energy consumption cost, such as utilizing the heat released from high-temperature composting in the later stage.
