  2. Description of the Related Art In recent years, in Japan, as income levels have improved, general households have an air conditioner (also referred to as “air conditioner” in the following description), a television receiver (also referred to as “TV” in the following description), a refrigerator. Or, household appliances such as washing machines, information equipment such as personal computers or word processors, office equipment such as printers or fax machines, and various other furniture, stationery, and toys are provided at a high penetration rate. . Convenience in home life has been dramatically improved by providing the above-mentioned various supplies in ordinary households.

  Since the above-mentioned various supplies are provided in ordinary households, the amount of disposal of these various supplies tends to increase year by year. Conventionally, recycling of these various materials has often been carried out through a scrap recovery route.

  Among the constituent materials of these various materials, the proportion of metals including iron tends to decrease, and the proportion of plastic compositions (also referred to as “plastic members”) tends to increase. Plastic members have a greater degree of design freedom than metals such as iron, can be imparted with various properties that are difficult to achieve with metals by preparing components and using additives, and are lightweight and durable This is because it has many advantages such as high performance.

  However, the plastic member has low value. In addition, the processing of the plastic member requires a lot of labor and cost as long as it is a conventional method. In the conventional iron scrap recovery route, it is not profitable to recycle such waste. From the viewpoint described below, it is becoming an important and urgent task to recycle waste of products including these plastic members (referred to as “plastic products” in the following description). The first point of view is to make effective use of resources. This is because many plastic members are based on fossil fuels such as crude oil. The second viewpoint is to prevent environmental destruction such as global warming and acid rain. This is because global warming and acid rain are caused by combustion of plastic members. A third viewpoint is to prevent environmental pollution such as generation and scattering of dioxins. This is because generation and scattering of dioxins are caused by incineration of a plastic member containing a chlorine compound. The fourth viewpoint is to suppress problems such as a shortage of landfill disposal sites. Since the plastic product waste is bulky, if the plastic product waste increases, the landfill disposal site will become insufficient.

  In order to solve the problems described above, the Home Appliance Recycling Law was enacted in April 2001. The Home Appliance Recycling Law requires that air conditioners, televisions, refrigerators, and washing machines be regenerated. The Home Appliance Recycling Law stipulates the legal standard values for air conditioners of 60% or more, TVs of 55% or more, refrigerators of 50% or more, and washing machines of 50% or more as re-commercialization rates of those products. The term “re-commercialization” refers to one of the following two types of actions. The first act is an act of separating parts and materials from the above-mentioned waste of household electrical appliances and using them as product parts or raw materials. The second action is an action of separating parts and materials from the above-mentioned household electrical appliance waste and making them available for transfer to a person who uses them as product parts or raw materials for a fee or free of charge.

  Improvement of recycling technology has made it possible to supply recycled plastics (plastics that can be recovered and reused) to some extent, so re-commercialization has been achieved to the extent that it meets the legal standards mentioned above. .

  Since re-commercialization has been achieved to the legal standards, the next step is to start a truly recycling-oriented approach. “True recycling” means that waste recovered from the waste of a plastic product is recycled and used as the same part of the same kind of plastic product. When true recycling is realized, the flow of conventional recycling changes. The “conventional recycling flow” is a flow in which recycled plastic is material-recycled only once into a low-quality product and then thermally recycled after being discarded again. When true recycling is realized, a recycling system in terms of quality will be established in which it can be reused for products with the same quality as the plastic before recycling.

  In a true recycling-type recycling system, it is desirable that a consumer can confirm how much the manufacturer has made the first re-commercialization described above. The method of clarifying how much the first re-commercialization has been done is to use the recycled plastic usage rate, for example, “This product uses 60% recycled plastic”. How to display.

  Referring to FIGS. 4 and 5, the program executed by server 30 performs the following control regarding the output of information.

  In step 110 (hereinafter, step is abbreviated as S), the communication unit 58 receives a packet from the terminal 32 of each recycling plant 22.

  In S112, control unit 42 determines whether or not the packet received by communication unit 58 represents the amount of waste by type of waste in each recycling plant 22, the amount of recycled plastic shipped, and the usage. If it is determined that it represents a processing amount or the like (YES in S112), the process proceeds to S114. If not (NO in S112), the process proceeds to S116. In S114, the control unit 42 stores information such as the processing amount received by the communication unit 58 in the processing amount database storage unit 52 and the like.

  In S116, control unit 42 determines whether the packet received by communication unit 58 is a packet for requesting an information presentation substance. If it is determined that the packet is for requesting an information presenting substance (YES in S116), the process proceeds to S118. If not (NO in S116), the process proceeds to S132.

  In S118, control unit 42 calculates a determination value based on the recycled plastic database. The determination value is a value for determining whether or not to send the information presenting substance. In the case of the present embodiment, the control unit 42 calculates the determination value by multiplying the sum of the shipping amount calculated by adding the latest shipping amount by the mixing rate of the information presenting substance. The “sum of shipment amounts calculated by adding the latest shipment amount” in the present embodiment is the total shipment amount for shipments two months before the latest shipment. In the case of the present embodiment, the control unit 42 determines by multiplying the sum of the shipment amounts of recycled plastics for applications with a useful life of 7 years or more by the mixing rate of the information presenting substance. Calculate the value.

  In S120, control unit 42 determines whether the required amount of information presenting substance is equal to or less than a determination value. The requested amount of information presenting substance is represented by a packet transmitted by the terminal 32. If it is determined that the required amount of information presenting substance is equal to or less than the determination value (YES in S120), the process proceeds to S122. If not (NO in S120), the process proceeds to S128. In S122, the input / output unit 60 displays and prints the destination of the information presentation substance and the requested amount under the control of the control unit 42. In S <b> 124, the input / output unit 60 receives the sending date / time of the information presentation substance from the operator of the management headquarter 20. In S126, control unit 42 stores the destination of the information presentation substance, the requested amount, and the date and time of delivery in the delivery amount database.

  In S128, the communication unit 58 transmits a warning packet to the terminal 32 of the recycling plant 22 under the control of the control unit 42. Thereby, the control part 42 will control the communication part 58 so that the information showing warning may be transmitted, when a determination value is contrary to the requirements with respect to a threshold value. In the present embodiment, “when the determination value violates the requirement for the threshold” means that the threshold exceeds the determination value.

  In S130, control unit 42 determines whether or not to end the output of information. If it is determined that the output of information is to be terminated (YES in S130), the process ends. If not (NO in S130), the process proceeds to S110.

In S132, control unit 42 performs processing according to the contents of the packet.
Referring to FIG. 6, the program executed by server 30 performs the following control with respect to usage rate communication.

In S <b> 140, communication unit 58 receives a packet from terminal 34 of user 26.
In S142, control unit 42 determines whether or not the user ID represented by the packet matches the user ID stored in advance in the measurement value database. If it is determined that the user IDs match (YES in S142), the process proceeds to S144. If not (NO in S142), the process proceeds to S148.

  In S <b> 144, control unit 42 determines the usage rate of recycled plastic using the measured value received by communication unit 58 and the mixing rate of the information presenting substance. This process corresponds to the processes of S160 to S174 described later.

  In S146, control unit 42 controls communication unit 58 to transmit a packet representing the usage rate determined by itself to terminal 34 of user 26. In S148, the communication unit 58 transmits a warning packet to the terminal of the user 26.

  In S150, control unit 42 determines whether or not to terminate the usage rate communication. If it is determined that the usage rate communication is to be terminated (YES in S150), the process ends. If not (NO in S150), the process proceeds to S140.

  Referring to FIG. 7, the program executed by server 30 performs the following control regarding the determination of the usage rate.

  In S160, control unit 42 stores “1” at a predetermined address in usage rate program storage unit 46. As a result, the value of the variable N is set to “1”.

  In S162, control unit 42 determines a provisional value of the recycled plastic usage rate. In order to determine the provisional value, the control unit 42 calculates an average value of the upper limit value and the lower limit value of the usage rate. In the case of the present embodiment, when the value of the variable N is “1”, the control unit 42 uses the maximum value and the minimum value of the usage rate included in the physical property value database as the upper limit value and the lower limit value of the usage rate. When the average value is calculated, the control unit 42 stores the calculated value at a predetermined address in the usage rate program storage unit 46. As a result, the average value of the upper limit value and the lower limit value of the usage rate is assigned to the variable A. The control unit 42 also stores the upper limit value and the lower limit value of the usage rate at a predetermined address in the usage rate program storage unit 46.

  In S164, control unit 42 determines whether or not the value of variable N is less than “7”. If it is determined that the value of variable N is less than “7” (YES in S164), the process proceeds to S166. If not (NO in S164), the process proceeds to S168. In S166, control unit 42 increases the value of variable N by “1”.

  In S168, control unit 42 outputs the value of variable A to communication unit 58. Thereby, the value of the variable A is determined as the usage rate of the recycled material.

  In S170, control unit 42 calculates a physical property value using the measurement value received by communication unit 58. In the case of the present embodiment, the magnetic permeability is calculated as the physical property value. In the case of the present embodiment, the measurement values received by the communication unit 58 are a magnetic force and a cross-sectional area. The “magnetic force” in this step is a magnetic force measured by the measuring device 36. The “cross-sectional area” in this step is a cross-sectional area of the product measured by the measuring device 36 when cut along a plane perpendicular to the magnetic field lines. The magnetic permeability μ is calculated by the following equation.

F = SH ² (μ) / 2
However, F represents the magnitude of the magnetic force measured by the measuring device 36. S represents a cross-sectional area. H represents the strength of the magnetic field. The magnetic field strength H is assumed to be known.

  When the magnetic permeability is calculated, the control unit 42 refers to the data in the physical property value database, so that the magnetic permeability calculated by itself is compared with the magnetic permeability when the recycled plastic usage rate is equal to the value of the variable A. Judge whether it is close to the upper limit value. If it is determined that the value is close to the upper limit (YES in S170), the process proceeds to S172. If not (NO in S170), the process proceeds to S174. In S172, control unit 42 substitutes the upper limit value of the usage rate into variable A. In S174, control unit 42 substitutes the lower limit value of the usage rate into variable A.

  The operation of the management system based on the above structure and flowchart will be described.

  When disposing of a TV, a refrigerator, an air conditioner, or a washing machine, the discarder attaches a recycling ticket purchased in advance to the waste, and then hands over the waste to a collection company. The collection company transports the waste to the recycling plant 22. Each recycling plant 22 dismantles waste. Each recycling plant 22 recycles the dismantled waste. The recycling plant 22 receives the recycling cost paid through the recycling ticket. The recycling plant 22 manages the management headquarters 20 with the number of wastes processed by item, the weight of the processed wastes, the weight of the remanufactured products, the breakdown of the remanufactured products, and the like. Report to 20. In order to report such information, the terminal 32 of the recycling plant 22 sends to the server 30 of the management headquarters 20 a processing amount for each type of waste, a shipment amount of recycled plastic, its use, and a specific property of the recycling plant 22. Send ID. The communication unit 58 of the server 30 receives packets representing them from each recycling plant 22 (S110). When the packet is received, the control unit 42 indicates whether or not the packet is a packet indicating a processing amount or the like (S112). In this case, since the packet represents a processing amount or the like (YES in S112), control unit 42 stores the received processing amount or the like in processing amount database storage unit 50 or the like (S114). When the processing amount or the like is stored, the control unit 42 determines whether or not to end the output of the sending amount (S130). In this case, since the process has not been completed yet (NO in S130), the processes of S110 to S114 and S130 are repeated.

  Thereafter, it is assumed that the terminal 32 of the recycling plant 22 transmits a packet for requesting an information presenting substance. In this case, since the packet is not a packet representing the processing amount or the like (NO in S112), control unit 42 determines whether or not the packet is a packet for requesting an information presenting substance (S116). In this case, since the packet is a packet for requesting an information presenting substance (YES in S116), control unit 42 calculates a determination value (S118). When the determination value is calculated, the control unit 42 determines whether or not the required amount of the information presenting substance is equal to or less than the determination value. If the requested amount is equal to or smaller than the determination value (YES in S120), the input / output unit 60 displays and prints the information presentation substance destination and the requested amount (S120). Thereby, the input / output unit 60 outputs the destination of the information presentation substance and the required amount of the information presentation substance when the determination value satisfies the requirement for the threshold. In the present embodiment, “the determination value satisfies the requirement for the threshold value” indicates that the threshold value is equal to or less than the determination value. The “threshold value” in the present embodiment is a required amount of the information presenting substance.

  When the destination and the requested amount are displayed and printed, the input / output unit 60 receives the date and time of sending the information presentation substance (S124). At this time, the information presentation substance is sent from the management headquarters 20 to the recycling plant 22. Each recycling plant 22 separates and collects plastic from waste collected from the market. When the plastic is separated and collected, each recycling plant 22 mixes the information presentation substance into the collected plastic at a certain mixing ratio. This “constant mixing rate” is included in the recycled plastics database.

  The method for containing the information presenting substance is not particularly limited. For example, the contained method includes a method of directly forming after drive blending by a drum tumbler, a method of compounding by an extruder, a method of compounding by an internal mixer or a heating lorry, and the like. It may be a method used after making a master batch. In mixing the information presenting substance, fatty acid amide, fatty acid metal salt, or fatty acid ester may be added as a lubricant in order to ensure uniform distribution and dispersion.

  The step of mixing the information presentation substance into the recycled plastic may be performed in a factory other than the recycling plant 22.

  When the information presenting substance is mixed in the recycled plastic, the input / output unit 60 receives the date and time of sending the information presenting substance (S124), so the control unit 42 sends the destination of the information presenting substance, the requested amount, and the sending date and time. It stores in the quantity database (S126).

  Through the above processing, the information presentation substance is shipped in an amount proportional to the shipment amount of recycled plastic. Recycled plastics are processed into products after being shipped and distributed to the market. A company that uses recycled plastic acquires a company ID. The server 30 registers the company ID and information about the company that acquired the company ID in association with each other in the information presentation substance database.

  After the product is distributed in the market, the user 26 measures the mixing rate of the information presenting substance in the product using the recycled plastic by using the measuring device 36 owned by the user 26. When the mixing rate is measured, the user 26 accesses the server 30 using the terminal 34 and acquires the user ID. The server 30 registers the user ID and the information transmitted by the user 26 when acquiring the user ID in association with each other in the measurement value database. When the user ID is acquired, the user 26 transmits the measurement value to the server 30. The communication unit 58 of the server 30 receives a packet from the terminal 34 of the user 26 (S140).

  In the case of the present embodiment, the information presentation substance is a ferromagnetic material such as iron or ferrite. The measuring device 36 is a device that measures the magnetic force received by a product when a product made of recycled plastic is sandwiched between two magnets and a uniform magnetic field is generated. Needless to say, the area of the two magnets described above is sufficiently larger than the distance between the magnets.

  When the packet is received, the control unit 42 determines whether or not the user ID represented by the packet matches the user ID stored in advance in the measurement value database (S142). In this case, when the user IDs match (YES in S142), control unit 42 sets the value of variable N to “1” (S160). When the value of the variable is set, the control unit 42 substitutes the average of the upper limit value and the lower limit value of the usage rate into the variable A (S162). When a value is assigned to variable A, control unit 42 determines whether the value of variable N is less than “7” (S164). In this case, since the value of variable N is “1” (YES in S164), control unit 42 adds “1” to the value of variable N (S166). When the values are added, the control unit 42 calculates the magnetic permeability using the magnetic force and the cross-sectional area received by the communication unit 58. When the magnetic permeability is calculated, the control unit 42 refers to the data in the physical property value database, so that the magnetic permeability calculated by itself is compared with the magnetic permeability when the recycled plastic usage rate is equal to the value of the variable A. It is determined whether or not it is close to the upper limit value (S170). FIG. 8 is a graph showing the relationship between the permeability and the usage rate of plastic when 1% of ferrite having a permeability of 15000 is added to recycled plastic. In this case, if the measured value is close to the upper limit value (YES in S170), control unit 42 substitutes the upper limit value of the usage rate into variable A (S172).

  When the upper limit value is substituted, the processes of S162 to S172 are repeated. Thereafter, when the value of variable N becomes “7” or more (NO in S164), control unit 42 sets the value of variable A as the usage rate of recycled plastic (S168). Thereby, the control unit 42 determines the usage rate of the recycled plastic by changing the provisional value of the usage rate a plurality of times according to whether the magnetic permeability is higher than the standard value represented by the physical property value database. Become.

  Thereafter, the control unit 42 controls the communication unit 58 so as to transmit a packet representing the usage rate determined by itself to the terminal 34 of the user 26. (S146).

  When the packet is transmitted, the control unit 42 determines whether or not to end the measurement value communication (S150). In this case, if communication of measurement values is terminated (YES in S150), the process is terminated.

  Thereafter, the terminal 34 of the user 26 outputs the usage rate transmitted by the server 30 to a display (not shown).

  As described above, the server according to the present embodiment centrally manages the information presentation substances to be included in the recycled plastic. Since the information presenting substance is centrally managed, the server according to the present embodiment can control the amount of the information presenting substance supplied to the recycling plant. Since the amount of the information presenting substance is controlled, the reliability of the recycled plastic used in the product is improved. The third party can know the objective usage rate of the recycled plastic of the product by confirming the amount of the information presenting substance.

  Further, the server according to the present embodiment presents the usage rate of the recycled plastic to the user based on the measured value measured by the measuring device. We do not disclose programs or information for presenting usage rates. Thereby, the usage rate of the recycled plastic can be presented to the user while maintaining the confidentiality of the information and managing the information centrally.

  As a result, the use of recycled plastic in products is promoted, and the display of the usage rate of recycled plastic can be made reliable, so that it is possible to provide an information output device that can reduce the use of fossil resources.

  As a modification, the measuring device 36 may be a device lent by the management headquarters 20. In this case, a device ID may be set in advance for each measuring device 36. During the period when the measurement device 36 is lent out, the control unit 42 of the server 30 registers the device ID and the user ID in association with each other in the measurement value database. In this case, in S142, control unit 42 may determine whether or not the user ID and device ID represented by the packet match the user ID and device ID stored in advance in the measurement value database.

  As a modified example, in S118, the control unit 42 calculates the determination value by multiplying the sum of the shipment amounts of any recycled plastics for any application by the mixing rate of the information presentation substance. Also good. Examples of “any application” include applications where the service life is 7 years or more, applications where the shipping amount exceeds a certain value, and applications used for household goods.

  Moreover, it replaces with the process of S118-S120, and the control part 42 may calculate the stock quantity of an information presentation substance as a determination value. In this case, the inventory quantity is calculated by the following formula.

Stock amount = total amount of information presentation materials sent to recycling plant 22−total amount of plastics shipped for recycling × mixing rate of information presentation materials When calculating the stock amount of information presentation materials, the recycling plastic database uses the shipment amount It is necessary to further include information representing the total amount of information presentation substances required from the information transmission source.

  When the inventory quantity is calculated, the input / output unit 60 displays or prints the destination and the requested quantity when the inventory quantity is equal to or less than the threshold value. The control unit 42 controls the communication unit 58 so as to transmit information indicating a warning when the stock quantity exceeds the threshold value.

  As a modification, in S118, the control unit 42 may calculate the shipment amount for the past two months based on the plastic processing amount for each item. FIG. 9 is a diagram showing the ratio of materials for a television, a refrigerator, an air conditioner, and a washing machine. FIG. 10 is a diagram showing the number of processed units and average weight per month for televisions, refrigerators, air conditioners, and washing machines. By multiplying the average weight, the number of treatments, and the proportion of plastic, the amount of plastic processed per month is obtained. By regarding the obtained plastic processing amount as the recycled plastic shipment amount, the control unit 42 can calculate the shipment amount. In this case, it is desirable to update the ratio of raw materials by item shown in FIG. 9 every year. This is because the data changes from year to year.

  As a modification, the communication unit 58 may transmit the packet encrypted by the control unit 42 in S146.

  As a modification, the data transmitted by the measurement device 36 may be encrypted data.

  As a modification, the server 30 may output the processing amount of the recycling plant 22, the recycled plastic shipment amount, or the lending status of the measuring device 36.

  As a modification, the server 30, the terminal 32, and the terminal 34 may be connected to each other via a communication network other than the Internet network. The “communication network other than the Internet network” includes an optical fiber network, a submarine cable communication network, a satellite communication network, or a combination thereof. Among these, those using a communication satellite for the communication network can realize high-speed and reliable information exchange regardless of the region where the server 30, the terminal 32, and the terminal 34 are located on the earth.

  As a modification, the information presenting substance may be one or more elements or compounds thereof (oxide, sulfide, organic oxide, etc.) that are not generally contained in the product. . Such elements include elements from element number 31 to element number 88. Of the elements from element number 31 to element number 88, lanthanoid elements, neodymium, promethium, samarium, europium, gadolinium, terbium and holmium are particularly preferred as the information-presenting substance. These elements are hardly contained in various plastics, paints, inks, and fibers. These elements can be easily measured with fluorescent X-rays. Furthermore, these elements are economical and hygienic and do not affect the physical properties of the material. In addition, these substances are easily available as compounds such as oxides. For these reasons, the above-described substances are suitable as information presentation substances. The shape of the information presenting substance is preferably a particulate substance having a diameter of 10 μm or less.

  When using the above-mentioned substances as information presentation substances, it is desirable that the mixing ratio is a slight mixing ratio that does not affect the properties of the product. Such a mixing rate varies depending on the type of product. Examples of such contamination range include the range from 0.1 ppm to 1000 ppm (including 0.1 ppm and 1000 ppm), particularly from 0.5 ppm to 200 ppm (including 0.5 ppm and 200 ppm). The reason why this range is desirable as the value of the mixing rate is to specify the usage rate of recycled plastic while ensuring sufficient reliability and keeping the economic burden low.

  In the case where the above-described substance is used as the information presenting substance, the measuring device 36 is preferably a fluorescent X-ray analyzer. The X-ray fluorescence analyzer measures the amount of fluorescence at a frequency having a peak by spectral analysis. Since the fluorescence amount is measured, the content of the information presenting substance can be detected. Since the content of the information presenting substance is detected, the usage rate of recycled plastic can be measured.

  As a modification, the information presenting substance may be a fluorescent substance that reacts with ultraviolet rays or infrared rays. In the case of the present embodiment, such a substance needs to be substantially white for the human naked eye. “Substantially white” means that after being contained in the plastic, it is so white that the naked eye cannot see the presence of the particles. Examples of fluorescent substances that react with ultraviolet rays include zinc sulfide activated with silver, copper, or manganese, zinc silicate activated with manganese, zinc sulfide activated with silver or copper, cadmium, or bismuth. Activated calcium sulfide, strontium sulfide activated with samarium or cerium, calcium tungstate activated with lead, strontium compound activated with europium, zinc compound activated with manganese, etc. And oxides of yttrium activated by europium and the like. The optimum average particle size is 0.5 μm to 5 μm. Other fluorescent substances include donor-acceptor type or cyanine type dyes and pigments containing an activator composed of rare earth ions in an oxide or halide matrix.

  When a fluorescent substance that reacts with ultraviolet rays or infrared rays is used as an information presenting substance, ultraviolet rays or infrared rays are irradiated for a certain period, and the intensity of the fluorescent light is measured. When the light intensity is measured, the usage rate of the recycled plastic is determined by referring to the usage rate database for the light intensity and the light intensity stored in the server 30 in advance.

  As a modification, the plurality of substances described above may be combined to form an information presentation substance. As a modification, the information presenting substance may be a substance corresponding to the use of the product. This is because the optimum information presenting substance differs between the case where the information presenting substance is used for durable consumer goods and the case where it is used for daily necessities. In this case, the server 30 stores information related to the information presentation substance and the use of the product in association with each other.

  As a modification, the controller 42 may use the following equation in calculating the magnetic permeability in S170.

μ = (1−K) μ (0) + KμF
μ is the magnetic permeability of recycled plastic mixed with an information presentation substance. K represents the mixing rate of the information presenting substance. μ (0) represents the magnetic permeability of the recycled plastic itself. μF represents the magnetic permeability of the information presenting substance.

  As a modification, in S170, when the control unit 42 calculates the magnetic permeability, the cross-sectional area of the recycled plastic orthogonal to the magnetic flux may be a value measured by a caliper or an optical method.

  As a modification, the terminal 32 of the recycling plant 22 may receive the mixing rate of the information providing substance. Thereby, the person in charge of each recycling plant 22 can confirm the mixing rate when necessary.

  As a modification, the server 30 may transmit information corresponding to the shipment amount of recycled plastic to a receiving device of a government agency or a computer connected to the Internet. The “information corresponding to the recycled plastic shipment amount” includes the manufacturer name, the model name, the usage rate of the recycled plastic presented by the manufacturer, and the usage rate of the recycled plastic calculated from the measured value received from the terminal 34. Such information may be disclosed on the homepage or the like by an administrative organization.

  As a modification, the terminal 32 of the recycling plant 22 may have the same function as the terminal 34 of the user 26. In this case, the recycling plant 22 has a measuring device 36.

  As a modification, it is desirable that the measurement device 36 is a device that is generally open to use under restrictions such as proving the identity of the measurer.

  Further, the management system according to the present embodiment may be used for recycled materials other than recycled plastics. In this case, the recyclable material is required to be a material that can be recycled and can be mixed or applied with an information presentation material. Examples of such recycled materials include recycled plastic and pulp.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
