<p><P>PROBLEM TO BE SOLVED: To provide a method for rapidly decomposing, on site in the ground without redigging nor pulling out to treat as an industrial waste, such land burial pipes for civil engineering and buried in the ground where almost no microorganisms lives, as an injection pipes, ground clean up pipes, search pipes for water quality survey which are made of biodegradable synthetic resins and are ones after accomplished the purpose of injection into the ground. <P>SOLUTION: The method comprises filling or injecting a material composed mainly of microorganisms as an effective ingredient into a buried underground pipe which is a biodegradable synthetic resin pipe buried in the ground and accomplished the purpose. The materials containing microorganisms as the effective ingredients may be a microorganism-containing biodegradable compost, soil, muck and clay, materials containing aerobe, anaerobe or the like as an effective ingredient, or an injection liquid obtained by mixing those in a dispersion liquid. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
