Features of AK System


Quality/safety of the recycled product (cement)

Recycled materials to be used in making cement can be detoxified by baking them at high temperatures in a cement-firing kiln.

We use a cement kiln to bake the recycled materials for use in cement. Cement kilns can maintain high temperatures of 1,450°C or more through continuous operation, thereby limiting the production of dioxins and eliminating foul odors.
The waste recycling kiln enables safe and environmentally friendly biodegradation treatment.

Bagged waste deposited into the recycling kiln is broken apart and mixed while being spun at low speed. Next, an aerobic biodegradation reaction is used to breakdown organic matter, transforming it into safe and sanitary recycled material. Furthermore, the gases generated during decomposition are used as air for firing the cement kiln, thereby eliminating all odors.
Total recycling that produced no secondary waste, such as ash, is achieved.

The combustible portion of recycled material is used as a fuel for firing the cement kiln, and the ash generated during firing is used as a raw material for making cement. This results in a total recycling system that does not produce any secondary waste. The percentage of recycled material used is kept below several percent of the total amount of raw material. This means there is no negative impact on cement quality, and heavy metal content can be controlled within a completely safe range.

Economic viability

Extends the life of final disposal sites because there is no need for a treatment plant.

Economic viability
Municipal waste is hauled by garbage trucks directly to the cement factory, where it is left in its bags when deposited into the waste recycling kiln to be treated. This eliminates the need for treatment (incineration) plants.


Contributions to the global environment

The AK System allows the energy produced by the incineration of municipal waste to be effectively used in cement firing, thereby replacing some of the coal used for that purpose, which in turn reduces CO2 emissions.
