| 摘要 | The present invention relates to a method for producing a sand aggregate, comprising: (a) a step of producing organic waste powders or by-product powders; (b) a step of mixing the organic waste powders or the by-product powders produced in step (a) with soil microbes; (c) a step of mixing the resulting material obtained in step (b) with sand to inoculate the sand with the soil microbes; and (d) a step of supplying water to the resulting material obtained in step (c), and aggregating particles of the organic waste powders and the sand by the growing mycelia of the soil microbes. The present invention produces a sand aggregate (preferably, sand cake, precast pavers or bricks, etc.) or reforms (preferably, fertilizes) sand using organic waste (or by-products), to reutilize waste (or by-products) and to thus prevent soil or water from being contaminated by organic waste (or by-products). Further, when the present invention is applied to the sand in which plants grow poorly, the sand is fertilized to promote the growth of symbiotic microorganisms, and to raise plants and suppress the use of chemical fertilizers and agricultural pesticides, thus activating environmentally-friendly green farming. Meanwhile, when the present invention is applied to the desert of China, which causes yellow dust storms, sand and red clay are provided with anti-scattering properties, to thereby prevent yellow dust storms and environmental contamination and damage to animals and plants caused by the yellow dust storms. | ||||||
