Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to environmental information management which utilizes information on the environment caused by the manufacture of products and the like, distributes it among companies, manages environmental impact information throughout the manufacturing process and life cycle, and uses it. About the system.

[0002]

2. Description of the Related Art Large-scale energy consumption and emission of harmful substances in all aspects of production and life today lead to pollution of air, water or soil, global warming and destruction of the ozone layer. In this situation, we are facing a serious danger of not being able to maintain the ecosystem and circulation system on the earth normally, that is, global environmental problems.

[0003] In some European countries, eco-friendly and recyclable products are marked with an environmentally compatible mark to encourage consumers to choose. In Japan, the number of companies certified by the environmental certification system (ISO-14001) has been increased, and the introduction and trial of the environmental pollutant emission and transfer registration system (PRTR) has been promoted, and it has been tracked whether specially designated waste has been disposed of properly. Management system (JP-A-4-32740)
No. 2) or a method in which a medium in which information relating to the disposal process is stored in a product is added to the final dividing process (Japanese Patent Laid-Open No. 8-27).
No. 7020).

In order to evaluate the environmental impact load of products, conventionally, harmful substances have been specified and the amount generated in the manufacturing process and the like has been examined. However, some, such as CO ₂ , are not directly harmful but can cause global warming. In addition, there are some cases, such as energy consumption, in which the environmental impact load cannot be correctly evaluated without examining the use (consumption) process of the product. Some dioxins, such as dioxins, produce a large amount of emissions depending on the disposal of products and the capacity of incinerators.

[0005] Therefore, from the resource extraction of a certain product (here, a product to be commercialized) to the production process that is shared by the company of materials, parts, and finished products, as well as the distribution, use (consumption),
LC that quantitatively calculates and evaluates the environmental impact of the disposal or recycling process, that is, the product life cycle
A method called Life Cycle Assessment (A) has been studied. The ISO-14001 system also evaluates the environmental impact using the LCA method.

[0006] The environmental impact load of items in the LCA, and coal, oil, and resource consumption, such as iron ore, NOx, SOx, air emissions such as CO ₂ used in the materials and energy, BO
D, COD, SS and other water discharges. And
The basic unit quantity of each process is accumulated for each item, and the environmental impact load is calculated for the whole or each category by multiplying the environmental impact degree (weight) different for each item.

[0007] As a proposal for improving the LCA method, a product life cycle model is described in a tree structure that is divided into a product side and a disposal side with a product as a root and a process as a node. JP-A-7-31176 for obtaining the sum
No. 0 and Japanese Patent Application Laid-Open No. 8-178832, in which the classification and weight of items are changed in accordance with the purpose of environmental impact evaluation, and a practical evaluation calculation considering accuracy and calculation amount are known.

[0008]

At present, most of the products on the market do not disclose or manage information on environmental impact at all. ISO-140
Despite the progress made in the PRTR 01 and PRTR, it is still an initiative between some companies and organizations and the competent authorities, and the mechanism and content of participation between companies and even general consumers has not yet been reached. In this regard, the current situation in which product users cannot easily obtain useful environmental information for product selection is a major obstacle to planning and promoting effective environmental measures by raising widespread interest in environmental issues. ing.

[0009] Today's global environmental problems are far beyond the local pollution problems caused by specific harmful substances, and efforts by some regions or some people alone cannot achieve results. Therefore, the reality of the global environment must first be grasped quantitatively by evaluating environmental impacts throughout the life cycle of all products, not by evaluating partial or sample environmental impacts. Such environmental impact information is not only useful to the competent authority that performs legal supervision, but also for the convenience of the company that creates the environmental information during each stage of the product life cycle, and for the general consumer and disposal company. If it does not meet the needs, it will not lead to increased interest and efforts in global environmental issues.

An object of the present invention is to collect, manage, and use environmental information comprehensively in view of the problems of the prior art, by using a mechanism and contents for distributing environmental information through a product manufacturing process and further through a rough cycle. It is an object of the present invention to provide an environmental information management system for the convenience of the user. As a result, widespread interest in global environmental issues will be raised, and effective countermeasures will be promoted.

[0011]

SUMMARY OF THE INVENTION The present invention relates to a method for managing environmental impact information in order to enable comprehensive management of environmental impact information throughout the entire manufacturing process of a product shared by a company and the life cycle of a product. Focusing on self-distribution, the necessary information content and management system were devised to achieve this.

[0012] The present invention to achieve the above object is a system in which a plurality of environmental information management devices provided for each company sharing a manufacturing process such as parts and assembly are connected by a public network. Network communication means, environment information generation means, environment information database,
An environmental information input device and an environmental information output device, wherein the environmental information generating means transmits environmental information of another product necessary for manufacturing the own product to the environmental information medium and / or attached to the other product via the environmental information input device. Incorporating from the environment information database of the other company via the network communication means, compiling the environment information of the other product and the environment information added by the manufacture of the own product for each item to create the environment information of the own product, In addition to being stored in an environment information database, the information is output to an environment information medium attached to the own product via the environment information output device.

The environmental information includes a product name (product name, model number, etc.), names and amounts of constituent substances required for manufacturing, energy consumption such as electricity, names of environmental pollutants and emissions,
Units unified for each item (for example, energy: kca
1).

The environmental information medium is a printed matter or an IC memory in which all or a part of the environmental information is recorded by characters or bar codes. In the case of recording a part of the environmental information, the entire contents are stored. The access address of the environment information database is added.

According to this, the environmental information database is made public through the Internet or the like, and the environmental information obtained at the upstream of the product manufacturing is carried downstream or branched and taken over.
Furthermore, it can be easily distributed in each process of distribution, consumption and disposal. In particular, by including the constituent substance information of the product, it becomes useful information in each process of manufacturing, consumption, and disposal, and its distribution can be improved. Also, anyone can easily read or access by attaching a recording medium (print label, IC memory, etc.) clearly indicating environmental information or its access destination to the product.

The system of the present invention is connected to an environmental information management device of a distribution company that distributes and sells products, and creates environmental information including the environmental information for each product, the number of sales, and the energy consumption required for distribution. And store it in the environment information database. The environmental information management device of the distribution company performs sales management and can use a POS system or the like.

Also, an environmental information management device of a garbage disposal company is connected, and this management device compiles each product by garbage type based on the environmental information of each distribution company in the jurisdiction, and an energy amount required for disposal processing. And emission of harmful substances are calculated and stored in the environmental information database. At the garbage disposal stage, the product becomes garbage, so that environmental information for each garbage type is managed. The environmental information for each type of garbage is useful information for drafting a work plan of a garbage disposal company.

Further, an environmental information management device of a recycling company is connected to the network, and the management device extracts information on recyclable materials and parts based on environmental information on discarded products, and extracts those materials and parts. Environmental information to which constituent material information and a recycle identifier are assigned is generated for each and stored in an environmental information database. This can promote the use of recycled resources.

Alternatively, an environmental information management device of a public organization such as a government office that evaluates or supervises the environmental impact load is connected, and the environmental information generating means of the management device is based on the environmental information received from the environmental information database of each company. , Calculate the environmental impact load for each product or company, and store it in its own environmental information database. This facilitates environmental ISO certification and supervision. Furthermore, by adding to the environmental information of each company by estimating the amount of energy consumption and emission of harmful substances in the product consumption process from the environmental information of the distribution company, comprehensive environmental information can be collected throughout the product life cycle. It is possible to evaluate the environmental impact load according to the actual situation.

If the environmental information database of each company or government office is integrated and configured as a data bank or an environmental information server, the device configuration of each company can be reduced, and access from others can be made easier.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the environmental information management system according to the present invention will be described below. The environmental information handled in this embodiment is based on unified raw material names and amounts used for manufacturing products, energy consumption such as electricity and gas, names of environmental pollutants such as mercury and NOx, and emission amounts. Converted to units, for example, 140 g of plastic, 5 g of iron, energy consumption of 1100 Kcal, NOx emission of 0.01 ppm
And so on.

The raw materials of the product and the amount of use are not essential as information relating to environmental pollution. However, since the processing method changes depending on the raw material, and the energy consumption and emissions often differ, this is useful information for fundamental understanding of environmental problems. In addition, composition or composition information is now required to be displayed on many products, and is not only necessary for downstream processes and consumers, but is also useful for systematic management of final disposal such as landfill and recycling. Therefore, since the environmental information includes the constituent substance information, the utility value can be increased, and the distribution thereof can be improved.

FIG. 2 shows the flow of products and environmental information in the manufacturing industry. Raw material (natural resources, etc.) ⇒ material processing ⇒ primary processing of products (parts, etc.) ⇒ secondary processing of products (assembly, etc.) ⇒
Logistics (transportation, sales, etc.) ⇒ Follow the consumer route.

Taking an automobile as an example, a material manufacturer melts iron ore and finishes it into a steel plate. The material name, usage fee and energy consumption required for this processing are added as environmental information to the product (steel plate) and passed (sold) to the next user. The next user is a body maker of the parts manufacturer A, and the iron plate is pressed into a car body. The environmental information required for this processing is also attached to the body and passed to the next automobile assembly and processing company. Because cars are assembled from various parts,
Parts companies B, such as engines, tires, lamps, interior parts, etc.
Also receives intermediate products and environmental information by C etc. The assembling company assembles the car from each part, sums up the environmental information attached to each part, integrates the energy consumption used in the assembly, and calculates the material name, consumption, and energy consumption of the whole car. Attached as environmental information of the car.

As described above, when the environmental information generated during the manufacturing process is distributed from the upstream process to the downstream process, all the materials required until the completion of the product, the amount of use thereof, the energy consumption, the environmental pollutants, and the like are generated. The amount can be comprehensively grasped. If this environmental information is disclosed in the same manner as the product specifications, consumers can select environmentally friendly products, so that the market principle works favorably for solving environmental problems.

FIG. 1 shows an embodiment of the environmental information management system. The environmental information management devices (computers) 2-1 to 2-4 of the companies A to D and the environmental information management devices (computers) 3 such as regulatory authorities are connected to each other via the wide area network 1 by the Internet or a public line. . The functions of the environment information management devices 2 and 3 typically include a network communication unit 10, an environment information database 20, and an environment information editing unit 30, as shown in the functional block of the computer 2-4 of the company D. , A barcode reader, an IC reader, etc., and an environmental information output device 50, such as a printer or an IC writer. The environment information editing unit 30 has an editing function according to an application such as a company or a government office. Environmental ISO14 is one of the governmental applications
There is a certification of the company that acquires 001.

In the environment information management unit 2 of the company D, the environment information editing unit 30 aggregates the environment information of the parts B and C in the previous process and the environment information generated in the own process for each item to obtain the environment information of the product D. The information is generated and stored in the environment information database 20, and the output device 50 creates environment information to be attached to the product D.

FIG. 3 shows a typical example of the data structure of environment information. FIG. 1A covers all items of manufacturer, model, serial number, constituent materials and usage, energy consumption, environmental pollutants and emissions. (B) consists of a manufacturer, a model, a serial number, and an environmental information access address. (C)
The content of (b) (or the content of (a)) is symbolized as a barcode.

If the company is a material manufacturer, the type of raw materials and their usage, and the amount of energy used such as electricity and gas, are expressed in kc
Environmental information such as energy consumption and harmful substances converted into al can be calculated relatively easily. Even in the parts processing industry, it is possible to read environmental information from a bar code or the like attached to a material, add environmental information by its own process, and provide it to the next user.

However, in a company such as a secondary processing or assembling factory, which handles a product composed of a large number of parts and a wide variety of products, it is not realistic to take in environmental information one by one from the parts. Also, the amount of environmental information to be output becomes enormous and cannot be handled by bar codes or the like.

Therefore, as shown in FIG. 3 (b), the manufacturer, model (and / or product name), serial number, and environmental information access address are printed directly on the product or in the form of a bar code. It is stored in the database 20. The user of the environmental information accesses the environmental information access address via the network 1 and acquires detailed contents of the environmental information such as constituent substances and energy consumption from the corresponding environmental information database 20 by designating a model and a serial number. I do.

As described above, since environmental information of each company is configured as a unified public database, downstream manufacturers and users can easily obtain upstream environmental information. The environment information database 20 uses the product name or substance name as a keyword regardless of the access address.
It is also possible to search for information on constituent substances and harmful substances from a database of a company. At this time, instead of using a database for each company, for example, a data bank that covers environmental information from the company database for each product is configured,
The system may be connected to the network 1 so as to easily search from the product name or the substance name.

FIG. 4 shows an example of calculating environmental information in the manufacturing process. The figure shows a calculation example of environmental information of a finished product in an assembly processing company. Environmental information attached to parts A, B, and C is taken in from a barcode reader 40 ', and environmental information of a part D made in-house is taken. After assembling the product, after assembling the product, the environmental information of each part is tabulated for each item of material and energy to calculate the environmental information of the completed product, which is stored in the environmental information database 20 of the environmental information management device 2 and the printer 50 '. Is printed on a barcode and attached to the finished product.

The end user, such as a general consumer, usually only needs to know the environmental information as a finished product, so that the environmental information at the component level can be omitted. However, in the case of the disposal process described below, component-level information is required, so the environment information of the read components or the component name or model and the access destination are stored in a separate file linked to the product's environmental information file and stored in a database. You may.

The environmental information management system of FIG. 1 is connected to an environmental information management device 3 of the government agency in charge. This computer 3 is, for example, an enterprise environmental authentication system (ISO-
14001) authentication and subsequent supervision. The environmental certification system (ISO-14001) requires analysis and management of the degree of impact on the environment by a company. Environment I
Companies that have been certified for SO are obliged to manage substances and energy that have an impact on the environment, such as the amount of energy used, the names and amounts of garbage and substances emitted, and report them to regulatory agencies.

In the environmental management system of the present embodiment, the environmental information of each company is centrally managed in a format and unit satisfying the standard of ISO-14001, and is a public database that can be accessed from anywhere. .
The computer 3 of the regulatory agency obtains information on the harmful substances and energy to be managed from the environmental information database 20 of each company online.
Edit and manage arbitrarily, such as by company or product.
Environmental information compiled by this regulatory agency is converted into a data bank,
It is made public so that anyone can access it from the network 1.

According to the present embodiment, since the environmental information of each company is configured as a unified public database, the supervisory agency can monitor the degree of environmental impact of each company on-line not only at regular reports but also at all times. The effect of suppressing the adverse effect on the environment is great. Further, since environmental information can be easily obtained by downstream manufacturers, distributors, and even general consumers, it is easy to select parts and products based on the environmental information.

Since the environment information of this embodiment is created so that the previous process includes the previous process, the environmental information can be realized without connecting a part of the company such as the previous process to the network. For example, even if environmental information on a part is provided only by direct printed matter or barcode, not via a network, if the post-process assembly company creates a database of environmental information on the product, distribution of environmental information can be achieved. Can be secured. As a result, the present system can be constructed without imposing an excessive burden on facilities for micro enterprises and agricultural workers.

Incidentally, environmental information of a product continues to be generated throughout its life cycle even after the end of manufacturing. FIG.
Figure 2 shows the life cycle of a product (commodity) and the distribution of environmental information. Products completed at the factory are transported as products to various locations by logistics companies and reach general consumers through dealers.
In the process of distribution, sales, and even consumption (use), environmental information is accumulated due to energy consumption such as fuel and exhaust gas of CO ₂ and NOx. In addition, garbage or recycling plants where products are disposed of as garbage,
There is new environmental information.

Therefore, acquisition of environmental information throughout the life cycle from product manufacture to final disposal is indispensable for fundamental measures against environmental problems. To do this,
It is important to distribute environmental information until the final disposal according to the product life cycle.

In the process of consumption, it is impossible to expect ordinary consumers to calculate environmental information. But the power of each home,
Gas, by calculating gasoline, kerosene, supply companies side usage such as water, energy consumption in the process of consumption, the estimated amount of released such CO ₂ and NOx is possible. In other words, the environmental information is calculated not from the energy consumption and harmful emissions of individual products but from the consumption of products (electricity, gasoline, etc.) used in the consumption process, and the company that sells and supplies these products has a It is managed in the information database 20.

For a specific product, for example, an automobile, an environmental information IC
Equipped with a memory, it is also possible to directly collect environmental information during the consumption process for individual products with high environmental impact, such as collecting environmental information calculated from accumulated fuel consumption and mileage at the time of vehicle inspection. is there. By using these pieces of individual information together, the emission amount of the harmful substance estimated from the gasoline consumption amount or the weighting factor for the estimation may be corrected on the database of the regulatory agency. In such a form, as the cost of the IC memory decreases, the applicable products will be greatly expanded in the future.

As a result of the consumption, the product changes to garbage, converting from valuable to vain, so that environmental information must be distributed with the garbage. For this purpose, it is unavoidable to expand the scope of legal regulations, such as the management of disposal among collectors, carriers, and disposal companies using manifest cards that have already been applied to hazardous specific waste materials.

However, it is difficult to distribute environmental information in general garbage only by legal regulations. In the present embodiment, the distribution of the waste is ensured by utilizing the environmental information as input information of the operation plan of the garbage disposal plant and recycling information.

First, a method of managing environmental information that can be used as input information for an operation plan of a garbage disposal plant will be described. The garbage disposal area has supermarkets, convenience stores, department stores, factories, hospitals, and other companies and facilities that emit so-called business garbage. Business garbage is, in principle, sorted and brought in by the company, so that environmental information can be calculated and managed for each processing content according to the above-mentioned manifest card, and can be used as input information for a garbage disposal site.

Next, garbage from general households having a high disposal ratio in a garbage disposal plant is only classified into incineration, landfill, and recycling at best. For example, the type and amount of garbage to be incinerated or landfilled cannot be grasped. Therefore, the type and amount of garbage are predicted from the sales amount of supermarkets and convenience stores in the garbage disposal site, and used as input information for the operation plan of the garbage disposal site.

In stores such as supermarkets and convenience stores, the amount of sales is reflected in the amount of garbage at a local garbage disposal site within a few days because of mass purchase and mass sales. In addition, in stores and chain stores that purchase a large amount of goods, inventory management, purchase management, and sales management are generally performed by a computer that has a POS system installed, and it is possible to grasp the goods sold and the quantity sold on a daily basis. Therefore, the store computer creates environmental information including the number and quantity of the sold products and the environmental information access address for each product, creates a database, and publishes the database on the network shown in FIG.

[0048] The garbage disposal plant or its operating company is provided with an environmental information database 2 published by stores in the area in which the garbage is disposed.
If you access 0 and obtain environmental information on a daily basis, you can search for constituent substances and amounts, harmful substances and amounts of goods as needed for garbage disposal, and sort garbage by garbage type such as incineration, landfill, recycling, etc. Is estimated and the total is added together with the above-mentioned business garbage, and a garbage disposal plan two to three days later is drafted using the contents of the total as input information.

Note that the prediction of the type and amount of garbage from the sales of goods may be realized by an environment information function added to the POS system of each store. That is, the environmental information of the product is registered in the POS system, or the environmental information database is accessed to obtain the environmental information of the product, and the environmental information of the garbage type is created from the environmental information of the product and the sales amount, and the public company is created. Publish to the body. Since the garbage disposal site only needs to add up the prediction information of the type and amount of garbage at each store, a practical local environmental information system is completed.

Next, a method of managing environmental information that can be used as recycling information will be described. As a first step, environmental information attached to the collected product is read, and constituent substances and harmful substances of the collected product are grasped. In addition,
Recyclable products, such as automobiles and refrigerators, often retain their original form, hold barcodes and IC cards, and obtain all or access to environmental information. As a result, a waste collection company or a recycling company can easily obtain useful information on collection and sorting of recyclable waste from the environmental information read via the computer terminal.

In the second stage, the information is provided as market information on recycled resources. Many recycled products are disassembled, classified, and recycled as parts and materials. In the present circumstances,
There is no systematic data on companies that require recycled resources and recyclers that have recycled resources.

In this embodiment, the parts and materials after the recycling process are regarded as a new product, and the recycler attaches the environmental information and creates a database of the details of the environmental information including the identification information “recycle” indicating the recycled product. To publish on the network. A company that wants to procure recycled materials can use a “product name” and “recycle” as search keys to search for a desired recycled product from a database connected to a network.

In today's environment where environmental issues have been highlighted, not only conventional functions and costs, but also environmentally friendly resources are beginning to be a choice in corporate materials selection criteria. Due to this change in the corporate policy, it is thought that the environmental information or the recycling information according to the present embodiment will be an important item for material selection in the near future. In addition, as the distribution of environmental information progresses, the selection and elimination of products that have an adverse effect on the environment by users will progress, and progress will be made toward fundamental solutions to environmental problems.

[0054]

According to the present invention, environmental information in each process of manufacturing a product is obtained and managed so that it can be easily distributed from an upstream process to a downstream process. Make it easier to do.

Also, environmental information can be obtained throughout the product life cycle of the manufacturing process, distribution, consumption and disposal.
The actual status of substances and energy that have a negative impact on the environment can be accurately and in real time grasped, and this information is useful for monitoring by supervisory authorities and environmental measures.

Further, since the environmental information includes a substance composition (component) and is a valuable information for downstream companies, general consumers, and recycling companies, the voluntary circulation of the environmental information is enhanced. Normal operation of the system can be ensured.
