<p><P>PROBLEM TO BE SOLVED: To provide a method for easily producing a plant growing carbide board given by using waste consisting mainly of domestic animal's excrement as a starting raw material, enough containing nutritive components for growing a plant, and therefore suitable for growing the plant, without polluting of the environment, etc. <P>SOLUTION: This method for producing the plant growing carbide board comprises subjecting the waste consisting mainly of the domestic animal's excrement to dry methane fermentation, carbonizing residues obtained in the fermentation at a temperature of 400°C to 800°C, mixing a carbonized material obtained in the above with granular charcoal and a fibrous material of waste paper derived from plants in such a ratio as to obtain a mixture comprising 4-6 pts.wt. of the carbonized material, 2-4 pts.wt. of the charcoal, and 1-3 pts.wt. of the fibrous material of the waste paper, and compression-molding the mixture into a board having a hardness of 10 mm to 20 mm (3.1 Kg/cm<SP>2</SP>to 6.3 Kg/cm<SP>2</SP>), so that the board is obtained as the plant growing carbide board. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
