Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

SUMMARY OF THE INVENTION The present invention relates to a technology capable of accumulating a large amount of garbage at a high density at a final disposal site of waste such as a stable disposal site, a management type disposal site, and a closed type disposal site. In particular, it prevents wind-borne garbage from scattering into the surrounding area, prevents rainwater and associated running water from entering and flowing out of the collected garbage, and prevents the collected garbage from wild birds and other areas. It is an object of the present invention to provide a novel film-forming method for a waste disposal site, which can be prevented from being destroyed by wild animals, and a waste film layer having a novel structure using the same.

[0002]

2. Description of the Related Art In Japan, industries and economies have continued to make great strides based on sophistication of technology, but their industrial structures and lifestyles cannot be considered as taking into account waste disposal. It must be said that corporate behavioral style, administrative style, people's consciousness of life, etc. have all become a waste increasing mass consumption society, and the large amount of waste generated every day is It is collected by each municipality for each administrative area, transported to incineration facilities or recycling facilities, etc., as appropriate, and disposed of as incinerated ash and non-combustible garbage. The biggest issue is to secure final disposal sites that are steadily decreasing.

[0003] In particular, in a metropolitan area, it is extremely difficult to secure a disposal site in the surrounding municipalities, and waste must be transferred to a remote private disposal site across neighboring prefectures. Shortage of final disposal sites has become a major social problem, such as waste disposal and illegal dumping by disposal companies. In order to solve such problems, the separate collection and recycling of waste have been actively conducted in recent years, and the amount of garbage has been gradually reduced. At present, it is necessary to construct new disposal sites one after another on rich beaches and mountain valleys. The desire to protect the scarce nature is gradually increasing.

[0004] In the final disposal site having these various problems, the stable disposal site, which is supposed to dump only rubber scrap, metal scrap, glass, ceramic waste, waste plastic, and construction waste, which are so-called five stable items, is also required. In addition to the continuing problems that harmful substances such as arsenic and arsenic and sewage have flowed out, new issues have arisen that the entry of malicious industrial waste has not been completely prevented. There is concern that leachate will contaminate soil and lower river basin at landfills and shut-off disposal sites, and that unburned waste will cause garbage to fly to surrounding areas due to wind, generate odors, generate toxic gas, and cause crows and rodents. It has been impossible to deny the possibility of the destruction of the natural environment and the adverse effects on the living environment of local residents, such as scattering by wild animals and the occurrence of flies.

As a technique for solving such a problem in the final disposal site, after the daily dumping work has already been completed,
Covering almost the entire surface of the waste at the disposal site with a waterproof synthetic resin sheet covers it, so that rainwater infiltration and leachate can occur, garbage can be scattered into the surrounding area, scattered by birds, and odorous. Although attempts have been made to prevent the leakage of garbage and the occurrence of pests, it takes a lot of time and time to collect the resin sheet covered on the waste before starting the work to carry in the waste every morning. There was a disadvantage that labor had to be spent.

In order to solve such a problem, a non-woven fabric sheet disclosed in Japanese Utility Model Laid-Open Publication No. Hei 7-21793, which has biodegradability and can be buried as it is even after covering the refuse disposal facilities, has been devised. In addition, it contains a bulking / setting material, a water-soluble polymer and water as disclosed in JP-A-8-505600, and provides a tough and flexible water-repellent coating layer after spraying. Sprayable compositions and methods for forming outdoor foam protective coating layers have been developed, but both are economically advantageous because all of the materials for forming the coating layer must be newly purchased. However, the problem of increasing the amount of waste at the waste disposal site has remained unsolved.

The present invention has been made in view of the above-mentioned facts of the treatment methods already proposed, and has the advantage of reducing the accumulation of waste as much as possible, accumulating waste at a high density within a limited volume of a disposal site, and Judging that it is not possible to realize a treatment method that also contributes to environmental preservation of the treatment plant and its surroundings, we started developing and researching it quickly, repeating trial and error over a long period of time, and numerous trial productions and experiments. As a result, this time,
Finally, a new waste landfill method and a waste film layer having a new structure used for the method have been successfully realized. The following describes some examples representing the present invention and the structure thereof. Will be described in detail.

[0008]

As will be clearly understood from the embodiments representative of the present invention which will be described later, the waste landfill method of the present invention basically has the following configuration.
That is, after the waste material dumped into the waste disposal site is subjected to a pressure treatment so as to be as flat as possible by a construction machine such as a bulldozer or a tractor shovel or other appropriate means, the waste plastic 1 pulverized into powder and granules is subjected to cement 1 -3, a hardening accelerator 0.5-0.1, a water-retaining agent 0.01-0.1 and water 0.5-1.5 mixed in a weight ratio of cement solution on the pressed waste. To a thickness of about 5 mm, and sprayed to form a continuous and closed coating layer, and after a lapse of a predetermined time, dump the waste again on the coating layer and pressurize. From the same cement solution, and a landfill treatment method in which a predetermined time elapses is sequentially repeated.

A more specific configuration of the waste landfill method having the above basic configuration is as follows. A waste dumped at a waste disposal site is disposed of by a construction machine such as a bulldozer or a tractor shovel or other appropriate means. After performing a pressure treatment so as to be as flat as possible, the waste plastic is pulverized into a granular aggregate, and the waste plastic 1 is cemented with cement 1-3 and a hardening accelerator 0.5-
0.1, water retention agent 0.01-0.1 and water 0.5-1.
The cement solution mixed at a weight ratio of 5 is sprayed substantially uniformly on the pressurized waste so as to have a thickness of about 5 mm, and is sprayed to form a continuous and closed coating layer.
After a predetermined period of time, the waste was dumped again on the coating layer, a pressure treatment was performed, a coating layer of the same cement solution was formed, and a landfill process was performed so as to allow the predetermined time to elapse. It can be called a waste landfill method.

[0010] Similarly, after the waste material dumped into the waste disposal site is subjected to pressure treatment by a bulldozer or a tractor shovel or the like or other suitable means so as to be as flat as possible, the waste plastic is crushed. Into a synthetic resin emulsion by mixing with an appropriate amount of a surfactant, and cement 1-3, a hardening accelerator 0.5-0.1, and a water retention agent 0.01-0 with respect to the waste plastic 1. 1 and water in a weight ratio of 0.5 to 1.5 are sprayed substantially uniformly on the pressed waste to have a thickness of about 5 mm, and dispersed and continuously and closed. After the elapse of a predetermined time, the waste is again dumped on the coating layer after the elapse of a predetermined time, pressure treatment is performed, and then a coating layer of the same cement solution is formed. Landfill processing method according to summary the configuration as repeated sequentially landfill encompasses.

More specifically, after the waste dumped at the waste disposal site is subjected to a pressure treatment by a construction machine such as a bulldozer or a tractor shovel or other appropriate means so that the waste is as flat as possible, the waste is ground into powder and granules. A cement kneading material obtained by previously mixing the plastics 1 at a weight ratio of the cement 1 to 3 and the waste plastics 1 with 0.5 to
0.1 of manol quick setting agent (trade name), 0.01 to
An aqueous solution consisting of 0.1 Metrolose (trade name) and 0.5 to 1.5 water is separately jetted toward the same place without mixing, and the cement kneading material is pressed on the pressurized waste. And the aqueous solution are sprayed so as to be mixed with each other, and
m to form a coating layer of a continuous and sealed cement solution so as to have a thickness of about m, and after a predetermined time elapses, rejects waste onto the coating layer and performs pressure treatment. It can be said that this is a waste landfill method in which a coating layer with the same cement solution is formed, and landfill processing for allowing a predetermined time to elapse is sequentially repeated.

Further, in the waste landfill method according to the present invention, after the waste dumped in the waste disposal site is subjected to pressure treatment by a construction machine such as a bulldozer or a tractor shovel or other appropriate means so as to be as flat as possible, At a moment of spraying, a cement kneaded material obtained by previously mixing the waste plastic 1 pulverized into a granular form at a weight ratio of cement 1 to 3 is added to the waste plastic 1 in an amount of 0.5 to 0.1. The ratio of manol quick setting agent (trade name), 0.01 to 0.1 metroze (trade name) and 0.5 to 1.5 water are added to form a cement solution, and the pressurized waste is added. About 5m above
m to a thickness of about m, spraying and spraying to form a continuous and closed coating layer, and after a predetermined time has passed, discard the waste again on the coating layer and pressurize the same. The method also includes a waste landfill treatment method having a configuration in which a coating layer is formed with a cement solution and the landfill treatment is performed repeatedly for a predetermined time.

[0013] The pressurizing treatment increases the storage density of the waste stored in the limited landfill facility, and also functions to arrange the upper part of the accumulated waste as flat as possible. The waste coming into the facility is compressed by construction machines such as bulldozers and tractor shovels or other appropriate means to eliminate irregularities, and the required amount of cement solution sprayed on the waste in a coating manner is reduced. Must improve the external aesthetics of the landfill and enhance the ease of landfill work at the next time.

Waste plastic is used as an aggregate of a cement solution to increase the strength of the coating layer, stop the growth of cracks generated in the coating layer, or form a synthetic resin emulsion by mixing with an appropriate amount of a surfactant to form a coating. It has the function of accelerating the drying of the coating and smoothing the surface of the coating layer. The coating is formed by mixing with an appropriate amount of granules or an appropriate amount of a surfactant in a range that is optimal as an aggregate for concrete. The surface of the layer should be smooth, and it should be finely pulverized to the extent that the property of improving drying and improving strength can be obtained. It is possible to mix in the cement solution at an appropriate ratio in an appropriate ratio, and to have both the properties as aggregate and the properties as synthetic resin emulsion. Waste plastic material that is less likely to dissolve in quality, does not require measures against sewage pollution or leachate at the time of final disposal, and is disposed of in a stable disposal site where it is filled with unearthed holes and covered with soil. It is desirable to recycle.

Cement is mixed with an appropriate amount of water to form a cement paste, and has a function of forming a coating layer continuously and hermetically with an adhesive force. A cement solution containing a synthetic resin emulsion obtained by forming a film or mixing waste plastic fine particles with an appropriate amount of a surfactant should form a film, and is generally used for construction in Japan. It is possible to use Portland cement and various mixed cements other than it, and it is also possible to use various admixtures and admixtures appropriately mixed, and it is possible to use specific gravity, fineness, coagulation, and stability. It can be said that it is desirable to use one that has a performance such as strength and the like that can withstand the construction of ordinary buildings.

The hardening accelerator enhances the adhesive strength of the cement solution and has a function of solidifying the coating layer into a relatively soft sheet at an early stage after spraying. The surface layer must be hardened into a film at an early stage, and it is desirable to use a quick-setting agent or an early-strength agent, and it does not cause cracks or pinholes in the coating layer even by rapid curing. You should choose one.

The water retention agent retains moisture in the cement solution and rapidly solidifies to prevent cracks and cracks, peeling from waste, etc., to achieve stable adhesion and fixation, and to rebound during spraying work. In addition to being able to replace and use a separation reducing agent, a thickening agent, a retarder, etc., these admixtures are used by mixing them in an appropriate ratio. You can also.

When water is sprayed on the waste,
In order to prevent the cement from splashing or splashing around, the cement solution is given a predetermined viscosity, and also functions to harden the cement itself in response to the mixed cement. It is desirable to use rainwater, river water, lake water, groundwater, drinking water, etc., without containing harmful amounts of substances that affect the quality of concrete, such as acids and salts.

The cement solution is sprayed onto the accumulated waste of irregular shape, thereby performing a function of forming a coating layer like a continuous and closed sheet. It is possible to spray beforehand as a mixture of cement, waste plastic, hardening accelerator, water retention agent, water, etc. beforehand, as well as a cement kneading material mixed with cement and waste plastic, water and hardening accelerator, water retention And a spraying agent onto the waste to form a coating layer. The film forming operation is performed by a construction machine such as a concrete pump truck or a concrete spraying machine or other appropriate means. Thus, it is possible to form a film having a predetermined thickness on the waste. The coating layer may be colored by appropriately adding a coloring agent so as to improve the appearance of the disposal site.

The cement kneading material is sprayed together with water onto the waste material to be supplied and becomes a cement solution exhibiting an adhesive force, and has a function of forming a coating layer having a predetermined thickness on the waste material. It is a mixture of cement and an appropriate amount of waste plastic aggregate in a dry state, and at the same time as spraying, a curing accelerator, a water retention agent, water, etc. are mixed, and a cement solution will be instantaneously formed. It should be supplied on the waste, and it is also possible to simultaneously spray a mixture of waste plastic in an appropriate weight ratio and an appropriate amount of a surfactant, which has been previously pulverized into fine particles in water, to form a film. .

[Related invention] In relation to the above-mentioned waste landfill method, the present invention also includes a waste film layer used in the waste landfill method, and the gist of the constitution is basically as follows. It is as follows. That is, cement 1 to 3 and hardening accelerator 0.5 to
0.1, water retention agent 0.01-0.1 and water 0.5-1.
The cement solution mixed at a weight ratio of 5 is dumped into a waste disposal site, sprayed onto the appropriately-filled waste to a thickness of about 5 mm substantially uniformly, and sprayed to form a continuous and closed state. It is a waste coating layer used in a waste landfill method having a structure in which a film is formed.

If the waste film layer included in the present invention is shown in a more specific configuration, cement 1-3 and manol quick-setting agent (trade name) are used for waste plastic 1 which has been made into aggregate. 0.5-0.1, Metros (trade name) 0.
A cement solution mixed at a weight ratio of 01 to 0.1 and water of 0.5 to 1.5 is dumped into a waste disposal site, and approximately 5 mm in thickness is appropriately placed on the waste which is appropriately pressurized. It can be said that this is a waste coating layer having a configuration in which a film is formed by spraying and spraying homogeneously to form a continuous and closed film.

Similarly, a finely divided waste plastic is mixed with an appropriate amount of a surfactant to form a synthetic resin emulsion, and the waste plastic 1 is mixed with cement 1 to 3 and a manol quick setting agent (trade name). 0.5-0.1, Metroose (brand name) 0.01-0.1 and water 0.5-
The cement solution mixed at a weight ratio of 1.5 is dumped into a waste disposal site, sprayed onto the appropriately-filled waste to a thickness of about 5 mm in a substantially uniform manner, and sprayed continuously and in a closed state. It can also be said that it is a waste coating layer whose main point is a structure formed by film formation.

The waste coating layer of the present invention is obtained by mixing a suitable amount of a synthetic resin emulsion obtained by mixing a granular plasticized waste plastic and a finely divided waste plastic with an appropriate amount of a surfactant. A cement solution obtained by mixing cement 1 to 3 with a plastic 1, a hardening accelerator 0.5 to 0.1, a water retention agent 0.01 to 0.1, and water 0.5 to 0.1 by weight, It is possible to dump the waste into a waste disposal site, spray it onto the appropriately pressed waste to have a thickness of about 5 mm in a substantially uniform manner and spray and scatter the film to form a continuous and sealed film, Since the thickness of the coating layer is affected by the uneven shape of the upper part of the waste, some changes are unavoidable.However, the continuity is tight enough to prevent inadvertent cracking and peeling by wind and wild bird mischief. Film thickness and viscosity to ensure It should be those formed to coercive. In the following, the structure will be described in detail with some embodiments representative of the present invention.

[0025]

Example 1 A rubber sheet having a thickness of about 1.5 mm was spread all over the bottom and side surfaces of the treatment space to prevent groundwater contamination, and leachate and rainwater were collected and properly treated in a purification treatment facility. When implementing one of the typical waste landfill methods included in the present invention in a managed disposal site that is required to be released later, a garbage truck or a transport vehicle that transports industrial waste Waste that is transported one after another by a bulldozer or tractor shovel, etc., or a special machine for trash transfer and pressurization, and then moved by the heavy equipment so as to be stacked sequentially from the back of the final disposal site. It is determined that the dumping operation should be performed as flat as possible, and the dumping work for one day should be completed after that, or the dumping work at the disposal site will be suspended for a while. Relative compartment, to form a waste coating layer by the following procedure.

AB that has been classified and collected by removing foreign matter in advance
Waste plastics such as synthetic resin molded products such as S resin, PP resin, and polycarbonate resin, and foamed plastics are washed and rinsed with a detergent as appropriate, and the diameter is 1 mm.
Pulverizing into granules of about 3 mm and drying as appropriate,
Alternatively, the cement solution was manufactured as a material that was attached to the granular plastic without being dried and contained in the water / cement ratio described below and mixed with the water / cement ratio, which was processed into granules and became available as aggregate. For waste plastic 1, Portland cement 2, a hardening accelerator manol quick setting agent (trade name) 0.75, a water retention agent Metrolze (trade name) 0.05, and pumped near the disposal site Tasawa, lake, bog, groundwater or stored rainwater is mixed at a weight ratio of 1 to make it homogeneous and supplied to a concrete pump truck. Sprayed sequentially in a spray or sprinkle shape, retreating while forming a continuous and sealed waste film layer having a thickness of about 5 mm on the waste, And waits for several hours drying obscures all waste Butsujo homogeneous waste coating layer.

On the next day or when the next dumping is performed, a heavy equipment for moving and pressing the garbage enters on the sufficiently dried waste coating layer, and the waste newly transported to the disposal site is sequentially removed. Move to the side, accumulate to the near side, after completing the loading work, pressurize it to make it flat as before, mix the same cement, waste plastic, admixture, water in the same ratio and spray, and A waste coating layer having a thickness of about 5 mm is continuously and hermetically formed and dried, and this operation is repeated until the controlled disposal site becomes full.

[0029]

[Embodiment 2] As another embodiment of the waste landfill method included in the present invention, the bottom and side surfaces of the disposal site are 10 mm thick.
The final disposal of industrial waste in a closed disposal site, which must be constructed so as to block water intrusion by covering it with concrete and a roof to prevent water intrusion, and to prevent contamination of surrounding groundwater. Will be implemented as follows.

That is, the incineration ash carried into the closed disposal site,
After the waste such as sludge, slag, dust, etc., is accumulated from the back side using a bulldozer or other appropriate construction machinery or a garbage transfer, a dedicated machine for pressurization, etc., and pressurized to a flat shape,
Waste plastics such as synthetic resin molded products and foamed plastics that have been classified and collected by removing foreign matter in advance are washed and rinsed with a detergent as appropriate, then pulverized into fine particles, dried, and dried. A cement kneading material was prepared by mixing cement at a weight ratio of 2 with respect to the waste plastic 1 thus obtained, and separately from the waste plastic 1,
With respect to the waste plastic 1, a manol quick setting agent (trade name) as a hardening accelerator having a weight ratio of 0.75 and a metroze (trade name) as a water retention agent having a weight ratio of 0.05. Water having a weight ratio of 1 is prepared, and each is supplied to a concrete spraying machine.

The cement kneading agent, manol quick-setting admixture, metroze and water separately supplied to the concrete spraying machine are adjusted and controlled so that they are simultaneously sprayed to the same place of the accumulated waste, and the rear side of the disposal site. The cement kneading material, manol quick-setting admixture, metroze and water ejected from the nozzle of the concrete spraying machine move while being sprayed sequentially from the top of the waste to the near side, and at the moment they collide with the waste, they are kneaded together. The cement solution forms a coating layer having a thickness of about 5 mm on the entire upper surface of the intended waste, and the outer peripheral edge thereof is continuously adhered to the concrete wall surface of the disposal site side wall. In addition, it is covered in a hermetically closed manner, and after drying, a waste film layer is formed.

Next, when dumping is performed, the waste is transferred and accumulated on the sufficiently dried waste coating layer in the same manner as described above, and then the cement is kneaded with a concrete spraying machine, a manol quick-setting admixture, Metrolose. Water is sprayed and sprayed to form a uniform waste coating layer having a thickness of about 5 mm on the upper side of the waste so as to be continuous and hermetically sealed, and then dried. It is intended to repeat until.

[0033]

The waste landfill method of the present invention having the above-described structure is obtained by crushing waste plastic on waste that has been accumulated in a controlled disposal site and compressed and flattened. Spray the cement solution containing the aggregate thus obtained into a uniform layer or spray it in a sprinkle form to form a waste coating layer with a thickness dimension of about 5 mm in a continuous and closed state. , The adhesive strength of the contained cement and the weight of the cement solution keep the waste coating layer on the waste, and the waste covered by the waste coating layer is a continuous waste coating over its coverage area. The layers are sealed and light wastes, such as paper, vinyl film, and granules, which are scattered by wind without waiting for the cement solution to dry, are suppressed by the adhesive strength and weight. Together it becomes or state, and that the coating layer be continuous obscures to prevent the blowing of direct wind.

Since the cement solution has a sufficient adhesive strength, the continuity and sealing property of the coating layer can be ensured even when spraying in the rain, and as a hardening accelerator contained in the cement solution. The manol quick-setting agent rapidly cures the surface layer of the coating layer in particular, preventing unevenness and runoff of the coating layer thickness due to dripping, and Metrose as a water retention agent delays evaporation of water in the cement solution. In addition to maintaining the flexibility of the coating layer for a long period of time, it also prevents cracks and pinholes from occurring, forms a sealed state, and prevents rain and the accompanying flowing water from entering waste. In addition, since the weight of the cement contained in the waste coating layer suppresses the waste on the lower side,
The waste once pressurized before spraying is settled under substantially uniform pressure over the entire surface.

Also, a suitable amount of a surfactant is mixed with waste plastic which has been pulverized to fine powder particles finer than cement to form a synthetic resin emulsion, and a cement solution containing this is sprayed. The synthetic resin emulsion accelerates drying, smoothes the surface of the waste coating layer and improves the appearance.Waste plastic in the form of fine particles prevents cracks from forming in the cement during drying, and causes cracks and pinholes. Will be prevented.

After the waste dumped in the shut-off type disposal site is pressed as flat as possible, the waste plastic is pulverized into fine particles using a concrete spraying machine and dried. A cement kneading material in which cement is mixed in a ratio of 2;
To the waste plastic 1 with a ratio of 0.75, a manol quick-setting agent (trade name) as a hardening accelerator, and a ratio of 0.05 as a water retention agent, Metrolase (trade name). Water at a rate of 1 at a time, the cement kneading material,
Manol quick-setting admixture, metroze and water work together to form a coating layer of cement solution, which prevents the cement kneading material, admixture and water from bouncing or flying up during spraying and impairing workability. In addition to the above, it is possible to prevent waste such as incineration ash, sludge, slag, dust, etc. from flying up as a splash by the force of the spray.

The waste film layer having a thickness of about 5 mm formed on the entire surface of the waste prevents leaching of rainwater or running water, and paper, film-like or powdery waste is blown by strong wind to the surrounding area. Prevents scattering, stops leakage of off-flavors,
By preventing the scattering of waste by wild birds and rodents, it is possible to improve the appearance and eliminate the necessity of covering and collecting work on sheet materials, and implement the waste landfill method every day or every predetermined period. By dumping so that the waste is sandwiched so as to form a plurality of layers between the plurality of waste coating layers while performing the pressurizing and covering of the waste coating layer,
Each layer is kept isolated, minimizing damage in the event of leachate,
This will promote the high-density integration of waste disposal sites.

[0038]

As described above, according to the waste landfill method of the present invention, the coating layer can be formed by spraying the cement solution after the end of the disposal operation. It is unnecessary, and it is possible to continue the dumping work by superimposing it on the previously formed coating layer, and it is possible to significantly improve the work efficiency,
It covers the waste dumped at the disposal site to prevent paper and particulate matter from scattering to the surrounding area, prevents the generation of leachate and the release of foul odors, scatters waste by wild animals, and In addition to reducing the occurrence and improving the appearance, it is carried into the disposal site,
By compressing the accumulated waste by a construction machine such as a bulldozer or tractor shovel or other appropriate means and flattening the pressure, and spraying a cement solution thereon,
Through the process of forming a waste film layer of about 5 mm, the above-mentioned pressurizing work and the sedimentation action of the continuous film layer on the dumped material due to its own weight, the accumulation of the aggregates enclosed under the film layer, the high density In the current situation where it is difficult to secure a new disposal site due to the fact that it is possible to achieve a landfill, it is an excellent feature that the life of the disposal site can be prolonged by effectively utilizing the volume of the currently available disposal site Is obtained.

According to the waste coating layer of the present invention,
Since all of its components are selected within the range of five stable items, no recovery is required. After stacking over the coating layer, dumping waste, accumulating and pressing, the coating is further layered. It is possible to form a layer and repeat it a number of times, by recycling the waste plastic by using the main component of the cement solution as a mixture of cement and crushed waste plastic, Achieving both a reduction in garbage and a reduction in cost.In addition, by mixing an appropriate amount of a curing accelerator and a water retention agent, it is possible to secure the adhesiveness to waste and the continuity of the coating layer to ensure tightness. This makes it possible to form an excellent coating layer, and to achieve an excellent effect of eliminating the exposure of waste and improving the external aesthetics of the entire repository.

In particular, the waste landfill method described in the embodiment and the waste coating layer used for the method are the same as those described above, and in addition to the above-mentioned features, a cement solution obtained by recycling waste plastic granulated by pulverization as aggregate is used. By using it, the durability of the coating layer can be improved by reducing the usage fee of cement and admixture, and furthermore, an appropriate amount of surfactant is mixed with the waste plastic ground into fine particles to form a synthetic resin emulsion. By mixing this with cement, the surface layer of the coating layer can be smoothed and the appearance improved, and drying can be promoted to eliminate problems such as dripping and runoff after spraying. A waste film layer with a uniform film thickness can be formed with the limited spray amount, and the work efficiency is dramatically improved by reducing the number of man-hours for spray work. It will be achieved a great feature that can be.

Further, cement 1 to 3, plasticizer 0.5 to 0.1, and water retention agent 0.01 to waste plastic 1
The cement solution mixed at a weight ratio of 0.1 to 0.1 and water of 0.5 to 1.5 is sprayed almost uniformly on the waste which still has a certain degree of unevenness even if it is pressed as flat as possible. It is an optimal blending ratio for forming a coating layer having a thickness of about 5 mm in a continuous and sealed state by spraying, and ensuring sufficient strength to withstand the natural environment such as wind, rain and snow. Thus, it is possible to achieve a special effect that the optimum viscosity and quick drying can be realized, and the sanitary management and workability of the waste treatment are remarkably improved.

As described above, the waste landfill method of the present invention and the waste film layer used for the method can achieve the intended purpose widely by its novel constitution, and the waste plastic is recycled. And can greatly contribute to the reduction of garbage. In addition, the use of only materials selected from the so-called five stable items minimizes adverse effects on the natural environment, and is easy and economical to construct. In addition to being able to efficiently utilize the volume of the disposal site by dramatically accumulating and increasing the density of waste, the construction of a laminated structure will solidify the scaffolding and transport waste. Since the safety and efficiency of the processing and transfer can be greatly improved, it is possible to reliably reduce the cost and the number of man-hours, and to efficiently use the final disposal site.
Industrial waste disposal companies and government officials, who are strictly concerned with sanitation and environmental protection, are also highly evaluated by related industries and organizations, and are widely used and spread. It is expected to be something.
