The invention relates to the organization of the storage of solid waste and can be used in the operation of solid waste landfills.

The known method of sanitary preservation of municipal solid waste, comprising coating the surface of the waste of the protective layer of nonflammable solid foam-based urea resin, which is applied to the surface of the waste by pouring that on the one hand provides the sanitary isolation of wastes from the environment, and on the other, due to the partial permeability of hardened foam does not lead to accumulation in the waste layer of explosive concentrations of gases formed during the processes of putrefaction and decay.

However, the method of operation of polygons using sanitary isolation of hardening foam-based urea resins require higher costs, so as to obtain the required air permeability of the foam it is necessary to conduct time-consuming activities for the selection of the composition of the foaming mixture. In addition, to obtain a layer of cured foam must use special equipment to control the thickness of the layer during its deposition and alignment of the not yet hardened foam immediately after its application.

As a prototype accept the way of sanitary conservation solid waste, see atent of the Russian Federation No. 2014164, consisting in coating the surface of the waste of the protective layer is partially permeable hardening foam based on a urea resin, a protective layer is applied by successive casting surface waste non-combustible or slow-curing foam, each subsequent priming is performed after hardening of the material of the previous fill.

The disadvantage of the prototype is the expensive way and a huge time costs, as each subsequent fill is carried out after the hardening of the material of the previous fill.

The aim of the invention is to reduce time and cost reduction method.

This goal is achieved by the fact that, as the breathable material used powdered composition of waste "dust of ferrous metals uncontaminated" metallurgical production and dolomite flour, mixed in a ratio of 1:3. The cooking process is the mixing of the components by mechanized methods. Three weight parts of dolomite flour or crumbs add one part of retreat the dust of ferrous metals uncontaminated" metallurgical production. The main methods are laying method "thrust fault" and the "confrontation". Laying of solid waste on the object placement method "thrust fault" is over is igenii next shaft waste created by 5-10 compacted waste layers up to 0.5 m, to the previous shaft. A compacted layer of solid waste height of 2 m is isolated by a layer of breathable material is 0.25 m (while providing a seal 3.5 times more Pets insulating layer thickness of 0.15 m). Storage of solid waste by the method of "confrontation" from the top down. In the method of "confrontation" as opposed to "thrust fault" the transport unloaded on top of an isolated object surface placement of solid waste, formed in the previous day. The intermediate layer of insulation in the storage of solid waste by the method of "confrontation" is 0.25 m, and the compaction of waste rollers KM-305 - 0.75 m To enhance biocidal action of retreat the dust of ferrous metals uncontaminated" metallurgical production introduces a highly effective drug, Bio Z". The drug, Bio-Z" is a strong fungicide and bactericide.

The application of the proposed method of conservation of solid waste provides reduced time and cost savings when performing the protective layer of the landfill through the use of a powder composition of waste "dust of ferrous metals uncontaminated" metallurgical production and dolomite flour, mixed in a ratio of 1:3. Cos the main methods are laying method "thrust fault" and "confrontation. To enhance biocidal action of retreat the dust of ferrous metals uncontaminated" metallurgical production introduces a highly effective drug, Bio Z". The drug, Bio-Z" is a strong fungicide and bactericide.
