Description

FIELD OF THE INVENTION

The present invention relates to a recycling system and recycling method. More particularly this invention relates to a recycling system and recycling method for comprehensively managing a recycle processing from a stage of materials for constituting a product to a stage of a final solid waste treatment.

BACKGROUND OF THE INVENTION

In recent years, there have been proposed various recycling systems for using reutilizable products, parts and materials by recycling them from the viewpoints of effective utilization of resources, reduction in waste volumes, cost reduction, and protection of earth environments.

As one of prior-art recycling systems, there is “Product Recycling System” as disclosed in Japanese Patent Application Laid-open (JP-A) No. 7-334583. This system is structured to have an input section for inputting product information, a memory for storing database of information on product reutilization, a recycle processing method decision processor for making a decision on a recycle processing of a product based on a predetermined recycling rule, by referring to the information on reutilization of the product in the database stored in the memory based on the product information input in the input section, and a recycling plant facility controller for functioning as an output section for outputting a result of the decision to a next process. Based on this structure, this application aims at promoting proper recycling of waste products, saving additional energy consumption, reducing waste volumes, and preventing environmental pollution due to toxic wastes and the like.

There is also “Recyclable Constituent Elements Having Data Recorder For Storing Information For Inspecting Constituent Elements, And Product Having Said Elements” as disclosed in Japanese Patent Application Laid-open (JP-A) No. 7-130295. According to this application, there is provided a memory unit for storing information on, for example, a position of a material to be recycled and information on a specific stress to be received during the use of a constituent element of a product. By using the information stored in the memory unit, it is designed to be able to suitably inspect each constituent element of a product before it is sent for recycling, and to be able to easily evaluate each constituent element taken out from the product.

According to the above-described prior-art techniques, however, a recycling of a product is carried out based on a decision made as to whether or not the product is to be reutilized as a part or the product is to be used as a raw material, only after the product as a waste has been recovered from the market. In this way, it is possible to easily evaluate each constituent element taken out from the product or to promote a suitable recycling of the product recovered. However, as the recycling is based on the assumption of products recovered, it is not possible to carry out a planned recycling manufacturing of products using recycled parts or the like.

Further, according to the prior-art recycling systems, it has not been possible to carry out a planned utilization of products in the market as parts or materials for products to be recycled, as the products once sold in the market are actually under the control of the market until when they are recovered as wastes and not under the control of individual recycling systems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment of a recycling system and recycling method according to the present invention is explained below with reference to the attached drawings, in the following order:

1) Concept of the recycling system of the present invention

2) Recycling system of the present embodiment

3) Use of the recycling system of the present invention.

In the present specification, in order to simplify the explanation, a recycling system will be explained by taking a copying machine as one example. However, it is a matter of course that the recycling system of the present invention is not limited to the copying machine. In the recycling system of the present invention, a part may be structured by one material, or apart maybe a unit of parts (an aggregate of parts). They will be collectively called a part or parts.

1) Concept of the Recycling System of the Present Invention

To begin with, a concept of a recycling system of the present invention will be explained.

First, the recycling system of the present invention is a reyling system for comprehensively managing a recycle processing of parts for constituting a product, from a stage of materials to a stage of a final solid waste treatment. The comprehensive management of this recycle processing will be explained in detail later with reference to FIG. 1 .

Second, according to the recycling system of the present invention, information on all reutilizable products, parts and raw materials is stored in advance as recycle information. Based on this recycle information, times when these products, parts and raw materials can be recovered as products, parts and raw materials for recycling are estimated together with their volumes. Then, based on the estimated times and volumes, a production schedule of a recycle product using the reutilizable products, parts and raw materials, is set.

Third, according to the recycling system of the present invention, at least one proposal of a composition of a virtual product is prepared by inputting a planned content of the virtual product. Based on the composition proposal and the recycle information, a decision is made as to whether it is possible or not to compose the virtual product using the reutilizable products, parts and raw materials. Then, based on a result of the decision, a virtual recycle product using the reutilizable products, parts and raw materials that can compose the virtual product, is designed.

Fourth, the estimated recovery times and volumes of products, parts and raw materials to be used for the virtual recycle product, are input based on a result of the designing of the virtual recycle product. Thus, a production schedule of the recycle product using the reutilizable products, parts and raw materials, is set.

(1) Concept of the recycling system for comprehensively managing the recycle processing from a stage of materials to a final solid waste treatment stage:

FIG. 1 is a conceptual drawing for showing a concept of the recycling system of the present invention as material flows from a stage of a raw material to a stage of solid waste treatment. Recycling is very effective means for reducing consumption of resources, by delaying the period from a material stage to its waste stage. As recycle processing methods for delaying the period from a material stage to its waste treatment stage, there are various kinds of recycle processing as designated by (1) to (6) in the drawing.

Life cycle stages of products, parts and materials will be explained next with reference to material flows from the stage of a raw material to a stage of its solid waste treatment, shown in FIG. 1 . In the drawing, reference numerals 1 to 20 denote life cycle stage numbers (hereinafter to be referred to as a stage No.).

Stage No. 1 shows a stage of production of a raw material. Generally, a raw material is produced and supplied by a raw material supplier.

Stage No. 2 shows a stage of producing a material by using a new raw material or a reproduced raw material. Generally, a material is produced and supplied by a material maker.

Stage No. 3 shows a stage of producing a part by using a new part or a reproduced part. Generally, a part is produced and supplied by a parts maker.

Stage No. 4 shows a stage of assembling a product by using a new product or a reproduced product. Generally, a product is assembled and supplied by a product maker.

Stage No. 5 shows a stage of selling a product using a new product or a reproduced product. Generally, a product is sold by a seller.

Stage No. 6 is a stage for showing a product using state/maintenance state. Generally, this shows a state that a product is being used by user (market).

Stage No. 7 is a stage for showing an own reproduction. This stage corresponds to a recycle processing of (1) described later.

Stage No. 8 is a stage for showing a recovery/selection of a product. Generally, a product is recovered from user (market) to a predetermined recovery center, and the product is selected to a next stage (stage No. 9 or stage No. 10 ).

Stage No. 9 is a stage for showing a reproduction of a product. Generally, a product is sent from the recovery center to a predetermined product reproduction center, for reproducing the product.

Stage No. 10 is a stage for showing a disassembling/classification of a product. Generally, a product is sent from the recovery center to a predetermined recycling center, for reproducing the product.

Stage No. 11 is a stage for showing a reproduction of a part. Generally, a part is sent from the recycling center to a predetermined parts reproducing center, for reproducing the part.

Stage No. 12 is a stage for showing a supply of a reproduced part to a product maker of other field. This corresponds to an open recycling.

Stage No. 13 is a stage for showing a fragmentation or crushing of a part (or a product). In this stage, a single material part is crushed, or a plurality of material parts are fragmented or classified. Generally, parts (products) are sent from the recycling center (the recovery center, depending on the case) to a predetermined shredder contractor, for fragmenting and classifying the parts (products).

Stage No. 14 is a stage for showing a reproduction of a material. A fragmented material that can be reused is sent from the preceding stage No. 13 to a material reproducer, for reproducing the material. When the reproduced material is sent to the parts maker (stage No. 3 ), this corresponds to a closed-loop material recycle processing to be described later. When the reproduced material is sent to a user of a recycled material (stage No. 15 ), this corresponds to an open-loop material recycle processing to be described later.

Stage No. 15 shows a stage of using a reproduced material. A reproduced material is sent from the stage No. 14 in the preceding stage to a user of the recycled material for their use of this material.

Stage No. 16 shows a stage of making a raw material from a recycled material. Shredded dusts are changed into the raw material by solving them into oil or heat/chemical cracking.

Stage No. 17 shows a stage of making a raw material from a recycled material. Printed substrates, shredded dusts, and the like are changed into a raw material by metallurgy.

Stage No. 18 shows a stage of using a reproduced raw material. A reproduced raw material is sent from the preceding stages No. 16 and No. 17 to a user of the recycled raw material.

Stage No. 19 shows a stage of recovering thermal energy. Thermal energy generated by incinerating shredded dusts is recovered by a thermal energy recovery contractor.

Stage No. 20 shows a stage of carrying out a final waste treatment. Generally, a final treatment contractor treats the solid wastes for reclamation or the like.

FIG. 2 is an explanatory table for summarizing detailed contents of behaviors corresponding to the life cycle stages from No. 1 to No. 20 shown in FIG. 1 , respectively.

With reference to FIG. 1 , the outline of the recycle processing from (1) to (6) and its effects in the recycling system of the present invention will be briefly explained in the sequence from the inner recycling group to the outer group.

(1) Own Reuse

This is a recycle processing for a user to reuse a part of a product by himself or herself. More specifically, this corresponds to a case where the user refills a toner into a toner container for refilling, for the user to reuse the container, for example. In this case, values of an object (a part to be reused) and its material are not degraded. It requires only minimum energy and minimum cost to recover to “a state of using by the user” which is a state of a highest value of the material.

(2) Reuse of a Product

This is a recycle processing for carrying out a predetermined reproduction processing to a recovered product, and reselling or reusing the recovered product. In this case, there is a large effect of reduction in environmental load, as most of parts and materials constituting the product are reused as they are.

(3) Reuse of a Part

This is a recycle processing for taking out a part from a recovered product, and reusing this part as a part of a new product. In this case, a part to be recycled is selected based on a service life of each part, amortization state, and a service life (product life) of a new recoduct. Generally, this has a large effect of reduction in environmental load, as the service lives of most of the parts are longer as compared with the life of the product.

(4) Material Recycle

This is a recycle processing for disassembling a recovered product, classifying parts into single materials, crushing and solving fragmented parts by heat, and using a result as a reproduced material. This recycle processing includes two types; a closed loop material recycling for reutilizing the material as a material for a product of the same field; and an open loop material recycling for reutilizing the material as a material of a product in other field. However, in the present embodiment, an explanation will be made basically by taking the closed loop recycling into consideration.

(5) Using as a Raw Material

This is a recycle processing for disassembling a recovered product, classifying parts into single materials, crushing and solving fragmented parts by heat, finally into a raw material, for reusing the reproduced raw material. For example, there are a chemical recycling for thermally or chemically disassembling a plastic material, for utilizing a result as a resin material, and a metallurgical recycling for taking out metal from shredded dusts by refining. The practicing of this recycle processing has a potential of achieving “no reclamation based on products” involving no direct waste treatment of materials.

(6) Energy Recovery (Thermal Recycling)

This is a recycle processing for incinerating plastics and the like, for recovering thermal energy. This recycle processing makes it possible to achieve an efficient utilization of energy.

In the recycling system of the present invention, all the above-described cycles of recycle processing from (1) to (6) are utilized as far as possible until a material reaches a final waste treatment stage, so that the life cycle of the material from the stage of a material to the stage of a final waste treatment is made longer, thereby to achieve effective utilization of resources.

Referring to the conceptual drawing of FIG. 1 , it is a matter of course that, in the case of selecting a recycle processing, it is desirable to place a priority to the recycle processing of a smaller loop as far as possible in order to minimize energy and cost required to recover to “stage No. 6 : the state of using by the user” which is the state of the highest value of the material.

2) Recycling System of the Present Embodiment

Next, there w ill be explained below a structure and an overall schematic f low of the recycling system of the present embodiment until a virtual recycle product is produced, with reference to a schematic configuration drawing of the recycling system of the present embodiment shown in FIG. 3 .

A recycling system of the present embodiment is broadly structured by a virtual warehouse 101 , a virtual recycle product designing section 102 , a production scheduling section 103 , a part procuring section 104 , a producing section 105 , and a selling section 106 .

The virtual warehouse 101 assumes all utilizable (and reutilizable) products, parts and materials including products in the market, parts mounted on the products and materials constituting the parts, as a product/part/material warehouse 101 a. Further, the virtual warehouse 101 manages the information on all the products, parts and materials on this product/part/material warehouse 110 a in a recycle information memory database 101 b.

In other words, the recycle information database 101 b stores as recycle information, the information on all the reutilizable products, parts and raw materials including products, parts and raw materials produced or used under the management of the system that are products, parts and raw materials treated as wastes and products, parts and raw materials currently being used in the market. Further, in the recycle information memory database 101 b, there is registered (stored) as recycle information the information required in executing each recycle processing shown in FIG. 1 . Details of this information will be described later.

The virtual recycle product designing section 102 has a function as a recycle recovery estimating unit for estimating times when products, parts and raw materials that can be used for recycling are recovered together with their volumes, based on the recycle information stored in the recycle information memory database 101 b, and a function as a virtual recycle product designing unit for inputting planned contents of a virtual product to be described later, preparing at least one proposal of a composition of the virtual product, making a decision as to whether it is possible or not to compose the virtual product using the reutilizable products, parts and raw materials based on the composition proposal and the recycle information, and designing a virtual recycle product using the reutilizable products, parts and raw materials that can compose the virtual product based on a result of the decision.

Further, the virtual recycle product designing section 102 designs a virtual recycle product according to market needs and needs of corporations. Other designing procedures will be described later.

Further, the virtual recycle product designing section 102 is provided with a specification limit input circuit 102 a for inputting whether a part satisfies specification (part specification will be described later) or not at the time of designing, a recycle production estimating circuit 102 b for deciding whether or not an output part satisfies specifications or for estimating costs, and a recycle production estimate output circuit 102 c for outputting a result of the decision made by the recycle production estimating circuit 102 b.

After the virtual recycle product designing has been carried out, specifications (component list) of the virtual recycle product, the number of the product that can be produced by recycling, and an optimum position of production, are decided. Then, parts are procured through the production scheduling section 103 for scheduling the production, and the product is produced.

The production scheduling section 103 inputs estimated recovery times of corresponding products, parts and raw materials together with their volumes, based on an output (a result of the designing) of the virtual recycle product designing section 102 , and designs a production schedule of the recycle product using the reutilizable products, parts and raw materials.

The part procuring section 104 procures corresponding parts from the virtual warehouse 101 , based on the production schedule set by the production scheduling section 103 . In this case, when an assigned part is being mounted on a product currently under use in the market, the procurement includes the case of forcibly recovering the corresponding product.

The producing section 105 produces the product according to the production schedule set by the production scheduling section 103 , by using the parts procured by the part procuring section 104 .

The selling section 106 sells the product produced by the producing section 105 . After the product has been sold in the market, the recycle information of the product sold is registered (or registered, or updated) in the recycle information memory database 101 b.

The component ratio is the information for showing the proportion of the above material components. The mixed volume of impurity is the information for showing to what extent what is called impurities such as, for example, a toner, a grease and others are mixed into the material at the time of using the material.

The above shows the contents of the recycle information 401 necessary for carrying out each recycle processing in the recycling system shown in FIG. 1 . However, in the present embodiment, the recycling of a copying machine in the recycling system is taken up as an example. Accordingly, when a recycling of other than the copying machine is to be carried out among various kinds of products and parts, it is necessary to sequentially add to the recycle information memory database 101 b the information particularly required for this recycling as the recycle information 401 .

Further, the recycle information 401 is provided corresponding to all the products, parts and materials on the virtual warehouse 101 . Further, the recycle information 401 is broadly classified into the product information 402 , the part information 403 and the material information 404 as shown in FIG. 4 . Further, the part information 403 has information on mounted product. It is possible to specify a product based on the information of the mounted product. As the information on the place of using the product exists in the product information 402 of the specified product, it is possible to specify a storage position or an installation position of all the products and parts by using the recycle information 401 . Accordingly, it is possible to utilize the recycle information 401 as the warehouse information.

Operation of the virtual recycle product designing section 102 will be explained in detail below. FIG. 8 shows one example of the specifications of a virtual product to be output as the virtual recycle product utilizing a recycled part. As shown in FIG. 8 , the specifications of the virtual product are classified into plan contents and design specifications.

At first, the plan contents of the virtual recycle product will be explained. Specifications (mounted functions) of the plan contents shows what kind of copying machine (copying speed, size of copying paper, size of the machine, appearance, durability, option contents, etc.) is to be provided, according to design needs and needs of corporations. Scheduled production date, lot number, place of production and cost are also items for constituting the plan contents. At the time of making this plan, a plurality of proposals are also made about how to recycle the product after the end of the life cycle in future.

The design specifications of a product will be explained below based on the plan contents (plan original proposal). Based on the above-described plan contents, a product and parts are designed. Then, a component list is prepared. The component list is a list for showing what kind of product is to be produced and what kind of parts are to be disposed at what positions by what number. In other words, the component list shows in a tree diagram drawing numbers of parts, and assembly drawing numbers including number of parts. Further, regarding the contents of the product and parts, the contents corresponding to those in the recycle information 401 shown in FIG. 4 are described in the component list.

FIG. 9 is a flowchart for showing the flow of processing of the virtual recycle product designing section 102 . At first, the plan contents (plan specifications) shown in FIG. 8 are confirmed (S 901 ). Then, based on the plan contents, a virtual product composition proposal, that is a rough composition proposal of the virtual product, is prepared (S 902 ). In this case, preparing the rough composition proposal is to make the whole layout of a copying machine, by determining a copying system, a paper carrying route, a draft scanning method, etc., in the case of a copying machine, for example. It is a matter of course that a plurality of composition proposals are investigated.

A decision is then made as to whether it is possible or not to structure a virtual product composition proposal by using a prior-art product (S 903 ). When it is possible to compose the virtual product by using a prior-art product (S 903 : YES), recycle parts and materials are selected by using the recycle information 401 of the recycle information memory database 101 b (S 913 ). Thereafter, parts to be introduced are determined at step S 909 , and the designing of the virtual product is finished.

On the other hand, when it is not possible to compose the virtual product by using a prior-art product (S 903 : NO), ideas of a plurality of virtual product composition proposals (for example, A, B, C) are evaluated (S 904 ). Then, an optimum composition proposal is determined (S 905 ). The idea evaluation includes the evaluation on the magnitude of environmental load (kinds of materials and their sizes), number of development personnel, development period, recycling factor of each part, cost, etc.

A detailed evaluation is then carried out based on the optimum composition proposal determined (S 906 ). Thereafter, parts specifications are determined (S 907 ). In this case, the parts evaluation includes detailed evaluation on values of environmental load information (materials and their sizes), contents of part structures (shapes, materials, sizes and qualities of parts of which tolerances have been determined are evaluated), and costs.

Subsequently, based on the part specifications determined at the step S 907 , a decision is made as to whether or not there exist reused parts that satisfy the part specifications in the mark, by using the recycle information 401 of the recycle information memory database 101 b (S 908 ). In this case, when there exist reused parts in the market (S 908 : YES), parts to be introduced are determined at step S 909 , and the designing of the virtual product finishes.

On the other hand, when there do not exist reused parts (S 908 : NO), a new part is designed for a corresponding part, and specifications of materials to be used are determined (S 910 ) Next, a decision is made as to whether or not there exist reused materials that satisfy the specifications in the market (S 911 ). When there exist reused materials in the market (S 911 : YES), parts to be introduced are determined at step S 909 , and the designing of the virtual product finishes. On the other hand, when there do not exist reused materials in the market (S 911 : NO), new materials are selected (S 912 ), and parts to be introduced are determined at the step S 909 , and the designing of the virtual product finishes.

After the designing work has been carried out in the above-described steps, the component list as shown in FIG. 8 is prepared and output. As the component list that includes the information on the procurement of parts, the recycle information 401 (product information 402 , the part information 403 and the material information 404 ) is output as described above. This includes information on part existence areas, operation information including, part use periods, estimated use completion times, and firm information on completion of product use based on users expression of intentions, and information on product lot numbers and part production periods.

Further, the virtual recycle product designing section 102 may further input design priority condition information for designing a virtual product or parts of the virtual product, and designs the virtual recycle product based on the design priority condition information. As the design priority condition information, there may be used, for example, information for showing priority orders of costs, a recycling factor, legal regulations, conformity with standards, materials, delivery date, or/and volumes. By inputting the design priority condition information, it is possible to design a virtual recycle product using parts of the earliest delivery date (that is, the recovery time and volume are sufficient), by placing the highest priority to the delivery date.

Next, the operation of the production scheduling section 103 will be explained in detail. FIG. 10 is an explanatory drawing for showing the processing flow of the production scheduling section 103 . The production scheduling section 103 is for making a production schedule based on the component list (information for generating a virtual product) determined by the virtual recycle product designing circuit.

At first, as shown in FIG. 3 , information is transmitted from the virtual recycle product designing section 102 to the production scheduling section 103 , through the recycle production estimating circuit 102 b and the recycle production estimate output circuit 102 c. Then, a decision is made as to the component list, number of units that can be produced, optimum place of production, etc.

Thereafter, a necessary number of procurement of parts is determined. Subsequently, a shortage in the market (that is the product, part and material warehouse) is confirmed based on the recycle information 401 of the recycle information memory database 101 b. Then, an order is placed for new design product, and a recovery instruction for recycle is given.

In this case, the production scheduling section 103 may further input delivery date, stock information, facility status, legal regulations, conformity with standards, or/and materials, as production limit information, and set a production schedule for the recycle product by judging the production limit control information.

Further, the production scheduling section 103 may further input production priority condition information for designing the production schedule of the recycle product, and design the production schedule of the recycle product, based on the production priority condition information. As the production priority condition information, there may be used, for example, the information for showing priority orders of costs, a recycling factor, legal regulations, conformity with standards, materials, delivery date, or/and volumes. By inputting the priority condition information, it is possible to set a production schedule of the recycle product that satisfies the delivery date, by placing the highest priority to the delivery date. Alternatively, it is also possible to produce the recycle product at low cost based on the schedule, by placing the highest priority to costs.

Thereafter, the part procuring section 104 procures parts. Then, the product (parts and materials) returns to the market through the producing section 105 and the selling section 106 . In this case, the information on all product sold including the product using the recycled parts is newly registered as the recycle information 401 in the recycle information memory database 101 b. In other words, in the present embodiment, as the market and the recycle information memory database 101 b are assumed as a part of the virtual warehouse 101 , the selling of the product in the market can be considered the same as storing the sold product in the virtual warehouse 101 as stock.

A product produced by the recycling system of the present embodiment is not a completely new product but is a recycled product using parts and the like once used in the market in at least a part of the product. Further, this recycled product may be a product in which the past functions are maintained with a prolonged service life. Alternatively, this recycled product may be an addition of a function to the past functions, or a deletion of a past function, or a combination of these. Further, new parts of a product may be parts of new functions or parts replaced because of the end of their service lives.

As explained above, the parts of a product in the recycling system of the present embodiment are being replaced by stage. During the period while the cycle of recycling is repeated by a plurality of times, all the parts of the product are replaced.

In order to achieve the above recycling system, it is necessary that a large-scale recycling plant for covering a wide area is installed at each suitable area to carry out a mass production of the recycle product. In this case, most of the centers and makers in FIG. 1 correspond to the recycling plant or part of the plant, although they are different depending on the stages of recycle processing.

Further, according to the recycling system of the present embodiment, it is possible to set a recycle production schedule in the recycling plants in a similar manner to that of producing new products in the conventional plants. Based on this recycle production schedule, it is possible to produce the recycle product systematically.

Further, according to the recycling system of the present embodiment, while it is possible to produce a recycle product systematically or based on schedules, it is also possible to recover products (parts) systematically or based on schedules, to match the production schedule. As a result, it is possible to achieve a planned recovery without generating waste of resources.

3) Use of the Recycling System of the Present Embodiment

Finally, use of the recycling system according to the present invention will be described below based on the above-described concept of the recycling system of the present invention and the recycling system of the present embodiment.

According to the recycling system of the present invention, the present invention has an object of systematically producing a recycle product using recycled parts and others. In order to achieve this object, the recycling system has various functions (means). Thus, the concept of a systematic recovery of products arises from the systematic production of the recycle product. Therefore, it is possible to propose a new mode of selling only the right of using functions of a product, not the product itself, to a customer (user) and charging the customer for this use, as an ideal business mode, by switching from the conventional business mode of production to selling and recovery of the product.

When the recycling system of the present invention is utilized together with the new business mode, it becomes possible to carry out a scheduled recovery based on a production schedule. This makes it possible to construct a more efficient recycling system.

Further, in the conventional business mode of selling a product, it is also possible to achieve a scheduled recovery by introducing such a system that a maker pays a recovery charge (what is called a part charge) to a customer and replaces the customer's product with an equivalent product or a product with improved function, at the time of recovering the product from the customer.

At first it may appear useless (expensive) to recover a product still in use in the market. However, this is not a useless act as the product disposed as waste according to the conventional practice is reborn as a recycle product. Particularly, when it is necessary to increase the function of a product during a short period of time after the user has started the use of the product, this product has been abandoned in the past. This has been a large waste of resources. Accordingly, achieving both a scheduled production and a scheduled recovery will bring about a large effect.

As explained above, according to the recycling system and recycling method of the present invention, information on all reutilizable products, parts and raw materials is stored in advance as recycle information. Based on this recycle information, times when these products, parts and raw materials can be recovered as products, parts and raw materials for recycling are estimated together with their volumes. Then, based on the estimated times and volumes, a production schedule of a recycle product using the reutilizable products, parts and raw materials, is set. Therefore, it is possible to systematically produce the recycle product using recycled parts and others.

Further, according to the recycling system and recycling method of the present invention, at least one proposal of a composition of a virtual product is prepared by inputting a planned content of the virtual product. Based on the composition proposal and the recycle information, a decision is made as to whether it is possible or not to compose the virtual product using the reutilizable products, parts and raw materials. Then, based on a result of the decision, a virtual recycle product using the reutilizable products, parts and raw materials that can compose the virtual product, is designed. Therefore, it is easily possible to systematically produce the recycle product using recycled parts and others based on a result of the designing of the virtual recycle product.

Further, according to the recycling system and recycling method of the present invention, the estimated recovery times and volumes of products, parts and raw materials to be used for the virtual recycle product, are input based on a result of the designing of the virtual recycle product. Then, a production schedule of the recycle product using the reutilizable products, parts and raw materials, is set. Therefore, it is possible to systematically produce the recycle product using recycled parts and others.

Further, according to the recycling system and recycling method of the present invention, the recycle information is warehouse information including product information on reutilizable products, part information on reutilizable parts, and material information on reutilizable raw materials, and for specifying at least storage positions or installation positions of the reutilizable products, parts and raw materials. Therefore, it is possible to manage all the products in the recycling system during the period from when the products are sold till when they are recovered. It is also possible to systematically utilize products in the market as parts and materials of a recycle product.

As explained above, according to the recycling system and recycling method of one aspect of this invention, information on all reutilizable products, parts and raw materials is stored in advance as recycle information. Based on this recycle information, times when these products, parts and raw materials can be recovered as products, parts and raw materials for recycling are estimated together with their volumes. Then, based on the estimated times and volumes, a production schedule of a recycle product using the reutilizable products, parts and raw materials, is set. Therefore, there is an advantage that the recycle products can be systematically manufactured using the reutilizable products, parts and raw materials.

Further, according to the recycling system and recycling method of another aspect of this invention, at least one proposal of a composition of a virtual product is prepared by inputting a planned content of the virtual product. Based on the composition proposal and the recycle information, a decision is made as to whether it is possible or not to compose the virtual product using the reutilizable products, parts and raw materials. Then, based on a result of the decision, a virtual recycle product using the reutilizable products, parts and raw materials that can compose the virtual product, is designed. Therefore, there is an advantage that the recycle products can be systematically and easily manufactured from the result of designing of the virtual recycle product using the reutilizable products, parts and raw materials.

Further, according to the recycling system and recycling method of still another aspect of this invention, the estimated recovery times and volumes of products, parts and raw materials to be used for the virtual recycle product, are input based on a result of the designing of the virtual recycle product. Thus, a production schedule of the recycle product using the reutilizable products, parts and raw materials, is set. Therefore, there is an advantage that the recycle products can be systematically manufactured using the reutilizable products, parts and raw materials.

Further, the recycle information is warehouse information including product information on reutilizable products, part information on reutilizable parts, and material information on reutilizable raw materials, and for specifying at least storage positions or installation positions of the reutilizable products, parts and raw materials. Therefore, there is an advantage that all the products can be managed with this recycle system after the sale of the products even if the products are yet to be withdrawn. In addition, the products in the market can be used as the parts and raw material of the recycled products.

Although the invention has been described with respect to a specific embodiment for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art which fairly fall within the basic teaching herein set forth.
