Every household should breed these flies

Yes, the post is several years old, but still worth your time to read:
Imagine a bioconversion process that reduces the weight and volume of food waste by over 95% within a matter of just a few hours. The process requires no energy, no electricity, no chemicals, not even water. The process is totally self-contained. It produces no effluent, and aside from a small amount of CO2, it produces no methane or other greenhouse gases. The process is housed within a container that resembles a small plastic garbage bin. The unit has no moving parts and requires no maintenance. Since it must be emptied but once a year, it eliminates altogether the collection, transport and landfilling of food waste. It can be situated out-of-doors in a shaded area, and any number of units can be coupled together to handle unlimited quantities of waste. The process generates very little odor, and at the same time, it very effectively repels houseflies and other filth-bearing flies. The unit requires very little expertise or experience to operate, it sells for less than $35 US dollars, and it can handle the daily food waste of more than 25 people. The process not only generates its own heat, but it also regulates and stabilizes heat to assure maximal bioconversion throughout the winter months.
With such efficiency and benefit, shouldn't every household breed some? It is Soldier Fly, native to America, but has already spread to the rest of the world including Australia. The conversion is done by its larvae.
[it] poses no threat to humans and has never been associated in any way with the transmission of disease. Yet at the same time, this benign creature possesses one of the most robust digestive systems within nature. It thrives in the presence of salts, alcohols, ammonia and a variety of food toxins. Upon reaching maturity, it migrates out of the unit and into a collection bucket without any human or mechanical intervention. This self-harvesting grub represents a bundle of nutrients that rivals in commercial value the finest fish meal. This creature can also be used to process poultry waste as well as human and swine feces.
