点からも好ましい。In the present invention, the agaric fungus culture bed is a culture bed obtained by culturing agaricum fungi using a compost obtained by aerobically fermenting horse manure, sawdust, rice hull, etc., so-called compost, as a medium. And
As a specific method of preparing a culture bed, for example, a method described in “Vegetable Horticultural Encyclopedia, published by Yokendo, 1985, pp1432” can be mentioned. The inoculum amount of the inoculum on the agaric fungus culture bed is usually 200 to 1000 g / m 2 . It is advantageous to use the culture bed after the fruiting body is formed in the present invention to cultivate the agaric fungus, and it is advantageous in that the decomposition of the plastic is performed efficiently. For example, edible enoki,
From the viewpoint of resource recycling, it is preferable to use a culture bed after cultivating agaricaceae such as mushrooms and harvesting fruit bodies.

And a mixture thereof. The shape may be various forms such as a lump or a film. Specific examples include hardly decomposable waste containing plastics such as PET (polyethylene terephthalate) bottles and urethane films, so-called hard-to-decompose plastic wastes.

できる。The amount of the culture bed relative to the plastic is usually about 10 to 1000 times by weight. In addition, urea, NPK chemical fertilizers and other nutrients in a culture bed can be added during the heat retention to allow coexistence. Because the nitrogen content in the culture bed is consumed during the cultivation,
It is preferable to add the nutrient, whereby the culture bed can be activated, and the decomposition of the plastic can be performed more efficiently. The addition concentration is usually about 0.02% or less in terms of ammonia ion concentration. For example, the nutrient can be added to the culture bed in the form of an aqueous solution.
