2. Description of the Related Art Recently, there has been a problem in processing wastes when constructing a building. As such waste,
There is wood from demolished wooden houses and construction waste wood such as concrete formwork. Such construction waste wood is currently processed by incineration, chip formation, or the like.

Further, recently, due to the diversification of life, a large amount of various kinds of wastes have been generated. Such wastes include, for example, food wastes such as leftover materials of food factories and household garbage, and animal excrements such as manure of animals raised in the livestock industry. These food wastes and animal wastes are treated by incineration, landfilling or the like, as with the above construction waste wood.

[0004]

However, in the case of treating the building waste wood, food waste and animal excrement described above by incineration, there is an inconvenience that a large amount of heat energy is required and it is discharged by combustion. There is the inconvenience of requiring exhaust and post-treatment of ash. In addition, the landfill treatment has a problem that it is difficult to secure a landfill site.

Further, in the treatment by incineration or landfill, there is a problem that illegal dumping is caused due to the above-mentioned inconvenience. Furthermore, disposal of waste by incineration, landfill, or illegal dumping may cause environmental damage.

[0006] Moreover, the construction waste wood has a problem that it is disadvantageous in terms of cost when it is considered to be reused as construction wood.

Therefore, it is desired to realize means for avoiding the above-mentioned inconvenience, enabling effective utilization of waste such as construction waste wood, and avoiding environmental destruction due to incineration, landfill, or illegal dumping. .

[0008]

In order to eliminate such inconvenience, the present invention forms a mixture by mixing building waste wood crushed into small pieces with food waste and animal excrement. An aerobic fermenting bacterium is mixed in the mixture, and the mixture is fermented with the aerobic fermenting bacterium under a predetermined environmental condition to produce a fermented product for soil improvement.

[0009]

According to the structure of the present invention, the organic matter of construction waste wood, food waste and animal excrement is fermented by aerobic fermenting bacteria to produce a fermented material for soil improvement,
An air layer can be formed by waste wood from construction to promote the fermentative action of aerobic fermentative bacteria, eliminating the need for conventional incineration and landfill processing, and eliminating the need for large amounts of heat energy and incineration. The subsequent exhaust and ash post-treatment may be unnecessary and may be processed at low cost.
