FIELD: process engineering. ^ SUBSTANCE: invention relates to collection and recovery of solid household wastes and other garbage, as well as to environmental protection. Proposed method comprises wastes sorting, clearing them outside residential block and placing. Recovery comprises producing layered substrate to grow plants in forming several uniform-height layers on surface of low-land areas with water-saturated soil, namely, layers of wastes, second porous layer of minced indecomposable wastes, and third surface layer of fertile soil. Then, willow cuttings are planted out in prepared substrate in bores made for entire height of substrate layers. Plants extract harmful elements from soil to reduce their concentration in time. ^ EFFECT: ruling out wastes blowing in wind, facilitating air cleaning. ^ 2 cl, 2 dwg, 1 ex |
