[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container for collecting plastic products made of waste plastic as a raw material, and a method of manufacturing and collecting a formwork panel made of waste plastic as a raw material.
[0002]
[Prior art]
Generally, so-called waste plastics (also called used plastics) such as container and packaging plastics and industrial waste plastics that are no longer needed are collected by local governments and businesses, and then sent to a recycling plant for reuse. Can be
[0003]
Recycling methods include material recycling, which recycles waste plastic as a raw material, chemical recycling, such as oiling, which reuses the chemical properties of waste plastic, and blast furnaces, which are a reducing agent in the steelmaking process, a type of chemical recycling. There are blast furnace reducing agent recycling that diverts into blown granules and thermal recycling that reuses waste plastic as a heat energy source.
[0004]
(A) Material recycling
In material recycling, waste plastic is crushed, foreign matter (glass, metal, stone, etc.) is removed from the crushed waste plastic, and a new plastic product is manufactured from the removed waste plastic. Because it is used as a new product, there are many restrictions such as aesthetics, strength, moldability, and hygiene issues. If different types of plastics are mixed, the required strength cannot be obtained. Therefore, measures such as strict separation for each type and further mixing of virgin raw materials as necessary are often taken.
[0005]
(B) Chemical recycling
A recycling method that thermally decomposes waste plastic and returns it to a monomer state. Examples include oiling methods, use in coke ovens, and the like. It is characterized in that it can be recycled even when various waste plastics are mixed, but the effects of additives and the like included in the molding of the waste plastics may not be negligible. For example, when vinyl chloride resin (PVC) is mixed into waste plastics in the oiling method, chlorine gas is generated in the pyrolysis process, causing equipment corrosion, and chlorine entering product oil, resulting in product contamination. Therefore, it is necessary to remove chlorine-containing plastics (PVC, PVDC) in advance because this causes deterioration of the quality of the steel.
[0006]
(C) Blast furnace reducing agent
As a reducing agent for reducing iron oxide in the iron making process, a plastic recycling method in which plastic is added instead of coke can be recycled without classifying waste plastic. If a large amount of chlorine-containing plastic is mixed, chlorine gas generated in the blast furnace may corrode the piping in the steelworks, so it may be necessary to remove chlorine-containing plastic (PVC, PVDC) in advance.
[0007]
(D) Thermal recycling
There is a method in which waste plastic is converted into RDF or incinerated in a combustion furnace as it is, and the combustion heat is recovered through a boiler or the like and recycled as thermal energy. Also in this case, it is necessary to remove chlorine-containing plastics (PVC, PVDC) because it causes dioxins to be generated at the time of combustion and there is a fear of equipment corrosion.
[0008]
[Problems to be solved by the invention]
Since conventional recycling systems were designed for primary products, the quality of the waste plastic that comes in is uniform for each product, and sorting, sorting, and classification are carried out to eliminate plastic products that do not contain specified substances. And plastic products (PVC, PVDC) containing predetermined substances. The predetermined substance is an unsuitable material for reuse, for example, chlorine.
[0009]
However, plastic products (secondary products) produced from waste plastics are collected as waste plastics after use, and recycled plastic products for secondary use are made from the collected waste plastics as raw materials. Waste plastics of various materials including the following products are collected. Since the amount of specified substances contained in these waste plastics varies, each time a plastic product is collected, the amount of the specified substances contained in the waste plastic is detected, and the collected waste plastic is classified according to the detection result. Work is required. Such a process complicates re-recycling and becomes a major obstacle in promoting re-recycling.
[0010]
The present invention has been made in view of the above circumstances, and its purpose is to greatly improve the recovery rate of plastic products for recycle, and to analyze and classify collected waste plastics. Can be used immediately as a material for recycle without the need for special treatment, thereby improving work efficiency and reducing costs for recycle, and consequently greatly contributing to the promotion of waste plastic reuse and environmental improvement.

[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
[1] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a production / collection management system for a plastic product such as a formwork panel. Reference numeral 1 denotes a manufacturing factory, which is a new plastic product such as a concrete form made from waste plastic (contained and packaged plastic) which has become unnecessary, particularly so-called waste plastic (also referred to as used plastic) such as container and packaging plastic and industrial waste plastic. For manufacturing panels and blast furnace blowing raw materials. The manufacturing factories 1 are distributed in various places. Note that each of the manufacturing factories 1 may belong to the same company or may belong to different companies.
[0023]
Each manufacturing plant 1 is provided with a manufacturing apparatus 2 for manufacturing concrete formwork panels and the like, a terminal 3 such as a computer, and a plurality of collection containers 12. Each terminal 3 can access the server 6 of the management center 5 via a communication line, for example, a communication network 4 such as the Internet. The server 6 has a database 7 for storing information where the various information related to the manufacture of concrete formwork panels is centrally managed, and publishes the contents of the database 7 as a web site. As a method of this disclosure, there is a case where only registered registrants are targeted, or a case where an unspecified number of anyone is targeted.
[0024]
FIG. 2 shows an example of the concrete formwork panel manufactured at each manufacturing plant 1.
Numeral 10 is a concrete formwork panel 10 which is used for construction, for example, for molding concrete used as a foundation of a building, and is expected to be shipped in large quantities as a material recycled product using waste plastic. Further, since a large amount is used on a site basis, a large amount can be collectively collected. Further, the individual concrete formwork panels 10 are considerably larger than household refuse, and can be collected while minimizing foreign matter removal. Identification information, for example, characters 11 is printed on at least one surface of the concrete formwork panel 10. As the character 11, alphabetic characters "A", "B", "C", and "D" are employed.
[0025]
The collection container 12 prepared in each manufacturing plant 1 is for receiving the used concrete form panel 10 for recycle, and as shown in FIG. At the same time, identification information such as a character 14 is printed on at least the front surface. As the letters 14, the same alphabet letters "A", "B", "C", and "D" as the concrete formwork panel 10 are used.
[0026]
Hereinafter, description will be made with reference to the flowchart of FIG. Although this flowchart stipulates that the manufacturing plant 1 can manufacture both a material recycled product and a blast furnace reducing agent, it is a factory that can manufacture only one of a material recycled product, a chemical recycled product, and a blast furnace reducing agent. You may. In that case, only a part of the flowchart of FIG. 4 is used.
[0027]
First, waste plastic that is no longer needed is collected by a local government, a business, or the like (step 101). If the collection container 12 is not used for this collection (NO in step 102), foreign materials (glass, metal, stone, etc.) are removed from the waste plastic based on the judgment that the first recycling for the primary use is about to start. ) And unrecyclable vinyl chloride products are separated and removed (step 103).
[0028]
After the removal of foreign matter, a material recycle product such as a pellet or a concrete form panel 10 is determined as a primary use, and the collected waste plastic is mixed and melted in the manufacturing apparatus 2 for the manufacture thereof (step 104).
[0029]
At the time of this mixing and melting, an analysis process for detecting the content of the substance contained in the waste plastic as the raw material is executed (step 105). Substances to be detected include chlorine, bromine, heavy metals, impurities (including types), additives (including types), and the like. Is detected.
[0030]
While this analysis is performed, in the manufacturing apparatus 2, the mixed and melted raw materials are pelletized or formed into the concrete form panel 10 (step 106). In this case, the concrete form panel 10 may be manufactured from the pelletized material, or the concrete form panel 10 may be manufactured directly from the melted material.
[0031]
Then, identification information corresponding to the content detected in the analysis processing is added to each of the manufactured concrete form panels 10 (step 107). For example, if the chlorine content is less than 0.5%, letter 11 of alphabet letter "A" is printed. Alphabet character "B" is printed at 0.5% to 1.0%, alphabet character "C" at 1.1% to 2.0%, and alphabet character "D" at 2.1% or more. You. This letter 11 is printed on the container or the like of the pelletized product.
[0032]
In connection with this printing, the data of the detected content and the data of the printed character 11 are sent to the server 6 of the management center 5 via the terminal 3 and the communication network 4 by the operation of the operator on the terminal 3. .
[0033]
The server 6 generates the analysis information file shown in FIG. 5 based on the reception from the terminal 3 and registers (stores) it in the database 7 (step 108). The analysis information file is a file in which the content (%) of the substance X (chlorine) is associated with the character 11, and whether or not it can be used as a blast furnace blown granule is added thereto. Whether it can be used as a blast furnace blown granule is automatically determined in the server 6 based on the content (%) of the substance X. The analysis information file thus generated is made public on the communication network 4 as a WEB site.
[0034]
The printed concrete form panel 10 is shipped to the market (step 109). That is, the concrete form panel 10 is transported to a construction site or the like by a predetermined distribution mechanism. Along with this, a collection container 12 with the same letter 14 as the letter 11 printed on the concrete form panel 10 is provided to the market (step 110).
[0035]
The shipped concrete form panel 10 is used at a construction site, and after that, is put into a collection container 12 as waste plastic. In this case, the worker puts the concrete formwork panel 10 on which the alphabetical letter “A” is printed into the collection container 12 with the same alphabetical letter “A”. Similarly, the concrete formwork panel 10 having the alphabetical letter “B” is put into the collection container 12 having the alphabetical letter “B”. The concrete form panel 10 with the letter “C” is put into the collection container 12 with the letter “C”. The concrete formwork panel 10 of the alphabet letter “D” is put into the collection container 12 of the alphabet letter “D”.
[0036]
At this time, the worker only has to select the collection container 12 having the characters 14 exactly the same as the characters 11 printed on the concrete form panel 10 as the object to be charged. No input is possible.
[0037]
In this way, the collection container 12 into which the used concrete form panel 10 is put is collected periodically or as needed, and transported to the manufacturing factory 1 (Step 101). At the time of this collection (YES in step 102), if members other than the concrete form panel 10 are included in the collection container 12, they are removed (step 111).
[0038]
Of the concrete formwork panels 10 in the collection container 12, those that have a small amount of dirt attached and are not damaged are judged to be reusable as they are (YES in step 112), and are initially shipped. It moves to a process (step 109).
[0039]
If the concrete form panel 10 having no character print is mixed in the collection container 12, the concrete form panel 10 is transferred to another appropriate process (NO in step 113). Other suitable treatments include chemical recycling, utilization in coke ovens, utilization in blast furnaces, or thermal recycling (combustion or landfill treatment in incinerators).
[0040]
Thus, only the concrete form panel 10 on which the characters 11 are printed remains in the collection container 12.
[0041]
The worker reads the characters 11 on the concrete form panel 10 in the collection container 12, accesses the server 6 by operating the terminal 3, and refers to the analysis information file of the database 7 through the display screen of the terminal 3 ( Step 114) Retrieve the content corresponding to the read character.
[0042]
If the reading character is "A", it means that the chlorine content is less than 0.5%. When the read character is "B", it is understood that the chlorine content is 0.5% to 1.0%. When the read character is "C", it is understood that the chlorine content is 1.1% to 2.0%. When the read character is "D", it is understood that the chlorine content is 2.1% or more.
[0043]
If the chlorine content is higher than a predetermined reference value, for example, 0.5% or higher (YES in step 115), a process of removing the chlorine from the waste plastic of the concrete formwork panel 10 is executed (step 115). 116), a recycled product is newly manufactured using the waste plastic after the removal as a raw material (step 117). For example, there is a diversion to a blast furnace blown granulate which becomes a reducing agent in an iron making process.
[0044]
If the chlorine content is less than 0.5% (NO in step 115), the waste plastic is used as it is as a blast furnace blow-in granulation without the need for chlorine removal treatment (step 116).
[0045]
These recyclables are shipped to the market (step 118).
[0046]
In addition, from the analysis information file of the database 7, not only data on the content but also data indicating whether or not the blast furnace blown granules can be used are registered. By looking at the data, the worker can determine whether the concrete formwork panel 10 needs to be subjected to chlorine removal treatment or can be diverted to blast furnace blown granules without chlorine removal treatment. Can be determined at a glance.
As described above, with the shipment of the concrete form panel 10, which is a recycled product for the primary use, the collection container 12 for collecting the concrete form panel 10 as waste plastic is provided to the market, so that it can be recycled. The recovery rate of the concrete formwork panel 10 for the purpose can be greatly improved.
[0047]
In addition, the concrete form panel 10 detects and detects in advance how much chlorine, which is unsuitable for reuse at the time of recycle, is contained in the concrete form panel 10, and the character 11 corresponding to the detected content is used for the concrete form panel. Since the collection container 12 printed on the panel 10 and having the same characters 14 as the printed characters is provided to the market, when the collection container 12 is collected, the concrete form in the collection container 12 is removed. Panel 10 is already in a state of being classified based on the chlorine content. Therefore, the collected concrete form panel 10 can be immediately supplied to the material of the re-recycled product without requiring any troublesome processing such as analysis and classification, so that the efficiency of the re-recycling operation can be improved and the cost can be reduced. In addition, together with the improvement of the recovery rate of the concrete formwork panel 10, it is possible to greatly contribute to the promotion of the reuse of waste plastic and the improvement of the environment.
[0048]
Further, since the content is registered in a database in the server 6 of the management center 5 and can be easily accessed and browsed from any of the manufacturing plants 1 via the communication network 4, the same content can be stored in any of the manufacturing plants 1. A high level of high quality recycle processing can be performed.
[0049]
In the above-described embodiment, the configuration is such that the worker himself / herself searches the content registered in the database 7 on the display screen. By inputting the information transmission request to the terminal 3, the information transmission request is transmitted to the server 6, and the server 6 stores the content data and the availability data corresponding to the contents (read characters) of the received information transmission request in the database 7. A configuration may be adopted in which the information is automatically retrieved and read from the server 6 and transmitted from the server 6 to the terminal 3 that is the transmission source of the information transmission request and displayed on the display screen.
[0050]
In the above embodiment, alphabetic characters are used as the characters 11 and 14. However, the present invention is not limited to the alphabetic characters, and kanji, hiragana characters, katakana characters, numbers, Greek characters, Roman characters, and the like can be used.
[0051]
Further, in the above-described embodiment, only one large character 11 is printed on the concrete form panel 10, but a large number of small characters 11 may be printed on at least one side of the entire area of the concrete form panel 10. Good. By arranging and printing the whole area, even if the concrete form panel 10 is broken and separated into small pieces, the characters 11 can be visually recognized.
[0052]
[2] A second embodiment will be described.
In the second embodiment, color information is used as identification information corresponding to the content.
That is, as shown in FIG. 10, the laminate layer 15 is attached to both sides of the concrete form panel 10 as color information.
The laminate layer 15 is prepared in at least four types colored differently from each other, such as green, blue, orange, and red. Among these laminate layers 15, a laminate layer 15 of a color corresponding to the detected content is selected and attached. For example, when the chlorine content is less than 0.5%, the green laminate layer 15 is attached. In the case of 0.5% to 1.0%, the blue laminate layer 15 is attached. In the case of 1.1% to 2.0%, the orange laminate layer 15 is attached. In the case of 2.1% or more, the red laminate layer 15 is stuck.
[0053]
Each collection container 12 is formed of a member of the same color as each laminate layer 15. These collection containers 12 are provided to the market with the shipment of the concrete form panel 10.
[0054]
Therefore, when putting the used concrete form panel 10 into the collection container 12, the worker sets the collection container 12 having the same color as the color of the laminate layer 15 attached to the concrete form panel 10. What is necessary is just to select as an input object, the selection of the collection container 12 is easy, and input without error is possible.
[0055]
After the collection container 12 is collected, the database 7 is referred to based on the color of the laminate layer 15 attached to the concrete form panel 10 in the collection container 12, and the chlorine content in the concrete form panel 10 is determined. Can be searched.
[0056]
Even if the concrete form panel 10 is broken and separated into small pieces, the color of the laminate layer 15 can be visually recognized.
Other configurations and operations are the same as those of the first embodiment.
In the present embodiment, the laminate layer is used for coloring. However, coloring may be performed by other means such as mixing a colorant with waste plastic.
[0057]
[3] A third embodiment will be described.
In the third embodiment, a character pattern 16 composed of a combination of a plurality of characters is printed on at least one entire surface of the concrete formwork panel 10. Even if the concrete form panel 10 is broken and separated into small pieces, the character pattern 16 can be visually recognized.
A plurality of collection containers 12 on which the same character pattern 16 is printed are prepared, and these collection containers 12 are provided to the market with shipment of the concrete form panel 10.
[0058]
The other configuration and operation and effect are the same as those of the first embodiment.
[0059]
[4] A fourth embodiment will be described.
In the fourth embodiment, a large number of picture patterns 17 are printed on at least one entire surface of the concrete form panel 10. Even if the concrete form panel 10 is broken and separated into small pieces, the picture pattern 17 can be visually recognized.

[0060]
Specific examples of the picture pattern 17 include a picture pattern 17a in FIG. 10, a picture pattern 17b in FIG. 11, and a picture pattern 17c in FIG. The pattern pattern 17a has a chlorine content of less than 0.1%, the pattern pattern 17b has a chlorine content of 0.1% to 0.5%, and the pattern pattern 17c has a chlorine content of 0.5% or more. Respectively.
[0061]
The other configuration and operation and effect are the same as those of the first embodiment.
[0062]
[5] A fifth embodiment will be described.
The production / collection management system for the concrete formwork panel 10 has the same configuration as that of the first embodiment shown in FIG. However, although the first embodiment has described the detection of chlorine that is unsuitable for reuse at the time of recycling, the fifth embodiment is characterized in that a suitable material for reuse at the time of recycling is detected. Having.
[0063]
Hereinafter, description will be made with reference to the flowchart of FIG.
First, waste plastic that is no longer needed is collected by a local government, a business or the like (step 201). If the collection container 12 is not used for this collection (NO in step 202), it is determined that the first recycling for the primary use is about to start, and the foreign material (glass, metal, stone, etc.) is removed from the waste plastic. ) And unrecyclable vinyl chloride products are separated and removed (step 203).
[0064]
After the removal of foreign matter, a material recycled product such as a pellet or a concrete form panel 10 is determined as a primary use, and the collected waste plastic is mixed and melted in the manufacturing apparatus 2 for the manufacture thereof (step 204).
[0065]
At the time of this mixing and melting, an analysis process for detecting the content of the substance contained in the waste plastic as the raw material is executed (Step 205). Substances to be detected include chlorine, bromine, heavy metals, impurities (including types), additives (including types), and the like. Here, as a substance P that is a suitable substance for reuse at the time of recycle, Bromine is detected.
[0066]
While this analysis is performed, in the manufacturing apparatus 2, the mixed and melted raw materials are pelletized or formed into the concrete form panel 10 (step 206). In this case, the concrete form panel 10 may be manufactured from the pelletized material, or the concrete form panel 10 may be manufactured directly from the melted material.
[0067]
Then, identification information corresponding to the content detected in the analysis processing is added to each of the manufactured concrete form panels 10 (step 207). Any of the identification information described in the first, second, and third embodiments can be used as the identification information.
[0068]
With the addition of the identification information, the data of the detected content and the data of the identification information are sent to the server 6 of the management center 5 via the terminal 3 and the communication network 4 by the operation of the operator on the terminal 3. .
[0069]
The server 6 generates an analysis information file based on the reception from the terminal 3 and registers (stores) it in the database 7 (step 208). The analysis information file is a file in which the content (%) of the substance P (bromine) is associated with the identification information. The analysis information file thus generated is made public on the communication network 4 as a WEB site.
[0070]
The concrete form panel 10 to which the identification information has been added is shipped to the market (step 209). Along with this, the collection container 12 provided with the same identification information as the identification information added to the concrete form panel 10 is provided to the market (Step 210).
[0071]
The shipped concrete form panel 10 is used at a construction site, and after that, is put into a collection container 12 as waste plastic. At this time, the worker only has to select the collection container 12 having exactly the same identification information as that added to the concrete form panel 10 as the input target, and the selection of the collection container 12 is easy and accurate. Input is possible.
[0072]
The collection container 12 into which the concrete form panel 10 has been put in this way is collected periodically or as needed, and transported to the manufacturing plant 1 (step 201). At the time of collection (YES in step 202), if members other than the concrete form panel 10 are included in the collection container 12, they are removed (step 211).
[0073]
Of the concrete formwork panels 10 in the collection container 12, those with a small amount of dirt and no damage are judged to be reusable as they are (YES in step 212), and the first The process moves to a shipping step (step 209).
[0074]
When the concrete form panel 10 without the character print is mixed in the collection container 12, the concrete form panel 10 is transferred to another appropriate processing (NO in step 213). Other suitable treatments include chemical recycling, utilization in coke ovens, utilization in blast furnaces, or thermal recycling (combustion or landfill treatment in incinerators).
[0075]
Thus, only the concrete formwork panel 10 to which the identification information is added remains in the collection container 12.
[0076]
The worker accesses the server 6 by operating the terminal 3 while referring to the identification information of the concrete form panel 10 in the collection container 12, and refers to the analysis information file of the database 7 through the display screen of the terminal 3. (Step 214) The content corresponding to the discriminated identification information is searched.
[0077]
If the chlorine content is less than the predetermined reference value (NO in step 215), a recycled product is newly manufactured using the concrete formwork panel 10 as a raw material (step 216) and shipped. (Step 217). For example, there is a diversion to a blast furnace blown granulate which becomes a reducing agent in an iron making process.
[0078]
If the chlorine content is less than 0.5% (YES in step 115), the concrete form panel 10 is shipped as it is as an additive to the flame-retardant material used in the television housing (step 218). ).
[0079]
As described above, with the shipment of the concrete form panel 10, which is a recycled product for the primary use, the collection container 12 for collecting the concrete form panel 10 as waste plastic is provided to the market, so that it can be recycled. The recovery rate of the concrete formwork panel 10 for the purpose can be greatly improved.

[6] Modified example
In each of the above embodiments, the case where the content of the predetermined substance is directly detected from the waste plastic has been described as an example of the method of obtaining the content of the predetermined substance, but the present invention is not limited to this. For example, there is a case where a predetermined substance such as chlorine is removed by using a wet separation apparatus, and it is known in advance how much the content is reduced depending on the operating conditions of the separation apparatus. In this case, the content of the predetermined substance can be obtained based on the operating conditions of the apparatus. In addition, in the case of adding a starting substance in manufacturing a material recycled product, the content (range) of the predetermined substance can be known based on the amount of addition.
[0084]
In each embodiment, a factory for manufacturing concrete form panels, a factory for manufacturing a blast furnace reducing agent, a factory for manufacturing chemical recycled products, a factory for performing thermal recycling, and the like are described without particular separation. In some cases, these factories produce one type of recycled product, while others produce multiple types of recycled product. For example, a factory that manufactures concrete formwork panels may manufacture panels from general waste plastics, and may also manufacture formwork panels from recovered used panels. In the case of a blast furnace reducing agent manufacturing plant, the reducing agent is manufactured by removing PVC from general waste plastics, and the reducing agent is processed from material recycled products by a treatment according to the PVC content as in the embodiment. Will be manufactured. The same applies to a chemical recycling product manufacturing plant.
