ECOSYSTEM CULTIVATION MATERIAL AND ECOSYSTEM CULTIVATION BLOCK

摘要

PROBLEM TO BE SOLVED: To effectively use wastes resulting from manufacturing the artificial light aggregate. SOLUTION: A fused adhesive ungranulated matter adhered to the wall surface of a rotary kiln when expansive shale is burnt is crushed by a drill to obtain a proper shaped ecosystem cultivation material 1. The ecosystem cultivation material is light because of 25% or more percentage of void and 0.8 to 1.7 specific gravity, and it has high water absorption to facilitate the growing of living thing such as moss or the like as well as high water purification ability.
