Organic matter, which constitutes organic waste, consists mainly of a combination of carbon and hydrogen in its molecular structure, and requires oxygen when it is decomposed by combustion or other means. In this case, general air is combined with carbon or hydrogen and combined with chlorine contained in organic materials. Dioxin is commonly referred to as a substance in which carbon, hydrogen, oxygen, and chlorine are combined. It is a highly toxic chemical that is known to be highly carcinogenic and cumulative.

Oxygen, which accounts for about 20% of the air, is directly related to the decomposition of organic wastes. When oxygen is activated in various ways, it becomes O-ionized and air containing a large amount of activated O-ions (active oxygen) is called "active air". "

Surprisingly, the present inventors have found that when treated with "active air" during pyrolysis of organic waste, the active oxygen (O-ion state) contained in "active air" first combines with chlorine during organic decomposition to stabilize Cl ₂ O and the like. It was found that it prevents the generation of dioxins by making it into a substance.

As a device for the activation of such air, it can be carried out preferably using a Q-Bit energy radiating device.

Q-Bit energy radiators emit energy that modifies the positron spin of the atomic nucleus.
