Description

The present invention relates to a regional combined recycling system that manages CO ₂ emissions generated in a certain region.

  Up to now, the modern industry, which has continued to grow, supported by mass production and mass consumption, has already occurred in large quantities from the process of manufacturing products, and all products shipped to the market, including disposable products produced, are Eventually it will be released as waste. Waste is a large amount of “garbage” as a waste, but the disposal of waste is not only a matter of quantity, but the quality problem of generation of harmful substances accompanying the treatment must be solved.

In the past, the annual amount of so-called general waste discharged from ordinary households exceeds 50 million tons nationwide, of which 75% is incinerated and about 10% is recycled directly. It was said that it was about 15% (according to NEDO in 1999). Incineration has advantages such as reduction of waste, harmlessness, no bromide, energy recovery by power generation and heat utilization, but generation of harmful substances such as dioxin and hydrogen chloride, increase in processing costs, and waste of resources. As is well known, environmental pollution that progresses on a global scale, such as acid rain accompanying the generation of CO ₂ , global warming, and destruction of the ozone layer, has become a serious problem.

The amount of CO _{2 in} the atmosphere, which was 275 ppm (capacity ppm) in the middle of the 18th century, has been increasing over the past 200 years, and is now said to be well above 350 ppm. Local efforts are important for waste disposal, planning for potential construction sites for waste treatment facilities, improving the waste recycling rate and reducing its management costs, aiming for regional zero emissions, and a system for recycling waste There are proposals such as the construction of a system that supports waste recycling plans so that recycled materials can be stably supplied to consumers.

  From these proposals, in order to take a step further and aim for a recycling-oriented society, zero emissions, that is, disposal, are managed by integrated management of environment-related facilities that process various types of waste in a given area. There are also proposals for a control system that realizes the zero state of objects.

However, these proposals are basically only proposals for how to collect and manage the waste generated in the area. What is needed now is not a solution to the problem of how to collect and manage the generated waste, but the real amount of waste by making the most of the waste generated locally. by reducing the by reducing the occurrence of CO ₂ is a concept from the viewpoint of saving the crisis of global warming.

In the past, a campaign called “Oath of 1 million Eco-Life (sponsored by the Environment Agency)” was held in which everyone vowed to take measures that could be taken in daily life to prevent global warming and encouraged each other. As can be seen in this movement, CO ₂ emissions, each one of the residents in their daily life and commercial activities, but it can expect a certain degree of effect by continuing the modest self-control and saving, what guidance In fact, it is actually difficult to voluntarily continue self-control and saving actions by one's own will, and it is necessary to construct a system that will continue to give some guidelines for the entire region to reduce CO ₂ emissions. Above all, it is important.

  The above campaign for the “Oath of 1 million Eco-Life” was completed in 1997, but the campaign to prevent global warming is not a problem that it can be completed by any time. This is a problem that must be continued as long as humanity exists on the earth.

  In addition, the meaning of “1 million people” in the “Ecolife 1 million people oath” movement was meant to call as many people as possible to participate. It is also an appropriate number as the smallest unit of region that forms one economic sphere including production and consumption.

By the way, the city of 1 million people is a city of the size of Shin Shizuoka City, Kitakyushu City, Sendai City, Saitama City, etc., but the “1 million people” referred to in the present invention is the waste generated in one area. It is a unit that forms a recycling loop that regenerates the product as a material, and does not necessarily mean a municipal unit.
The Latest Recycling Technology OHM 1993 JP 2004-78980 A JP 2004-1991 JP-A-5-342224 WO2002 / 039338

The problem to be solved is that there is no system that provides clear guidelines for reducing CO ₂ emissions that cause global warming for the entire region, including industry, as well as daily life. It is.

In the present invention, as a unit of one region constituting the system, for example, one million population region (Million Recycling Region) is formed as one unit, and a recycling loop for recycling waste generated in the region as a resource is formed. From the collection and transportation of waste discharged in daily life and business by the residents living in the city and businesses operating offices and factories in the area (hereinafter referred to as local residents) detecting or calculating the CO ₂ emission amount generated up to the predicted value calculated on the basis of CO ₂ emissions emitted local residents, the data of the target value for suppressing the CO ₂ generated in the local residents The main feature is that it is provided as guideline information necessary for the behavioral practice required for.

The system of the present invention collects, transports and processes CO ₂ emissions generated from collection and transportation of waste discharged from local residents to commercialization of recycled products produced using the waste as resources. , reproduction resources, to detect or calculated at each stage in the discharge process of the product processing, CO ₂ emissions are likely to identify the cause of the increase and the data including the CO ₂ emissions per certain timing as guidance information to expose the concrete numerical values to raise awareness of global warming prevention for local residents, CO ₂ tends voluntarily to practice actions necessary to suppress the occurrence, CO ₂ is thus discharged into the area Controlling the total amount of emissions to the target value can greatly contribute to the prevention of global warming.

In order to realize CO ₂ emission reduction that does not easily progress at the national level, first create a region with a population of 1 million as a model region, and then spread that region to adjacent regions one after another to create a region with multiple populations of 1 million people. By collaborating with each other, it becomes easier to achieve the target, and as a result, the sum of the global warming prevention campaign can be expanded from all over Japan to the world.

The present invention aims to control the total amount of CO ₂ emissions generated in the region, and collects and transports the waste generated in the region at the general information management center set in the region. Calculate CO ₂ emissions emitted from the entire system, including the combined treatment that is processed and recycled into products such as power, gas, metal, building materials, feed, and fertilizer, and the future CO ₂ emissions will be calculated from the calculation results. predicted, waste reduction these data as a guide efforts target the CO ₂ emissions was achieved by the information published to local residents is the emitters of the waste.

  FIG. 1 is a diagram showing an outline of a model in one area to which the complex recycling system according to the present invention is applied. This model assumes an optimized area 1 of 1 million people and shows the configuration of facilities in that area. In FIG. 1, the system according to the present invention comprises a relay base 2, a freight station 4, a stock yard 6, a composite processing facility 8, a product warehouse 10, and a general information management center 7 as main facilities. Yes.

  The relay station 2 is a facility that collects waste (garbage) from the local residents 11, the freight station 4 is a facility that collects the waste transported from each relay station 2, and the stock yard 6 is from the cargo station 4. The facility that temporarily stores the waste transported by the railroad 5, the combined treatment facility 8, is a facility that separates the waste in the stockyard 6 for each use and transports the waste to the treatment facility for each use.

  The combined treatment facility 8 is composed of a power center 8a, an organic resource recycling center 8b, and a clean treatment center 8c. The power center 8a is a facility that recycles the recovered waste mainly as electric energy, and the organic resource recycling center 8b regenerates the recovered waste as methane or methanol, or performs processing necessary for fertilizer conversion. The clean processing center 8c is a facility that performs processing to recycle the collected waste mainly into resources such as metal materials, building materials, chemicals, and gas.

FIG. 1 shows a state in which these processed products are finally stored in the product warehouse 10 as a recycled product (product) M. The general information management center 7 is a facility for managing information on each of these relay bases 2, 2..., Freight stations 4, 4..., Stock yard 6, composite processing facility 8, and product warehouse 10. These facilities are connected via the Internet to form a computer network, process the information collected along with the collection of information from each facility, and provide guidance information necessary for CO ₂ emission regulations through the Internet. It has a function to provide to the resident 11.

  In the system of the present invention, an environmental monitoring center 9 is installed separately from the above facilities. The environment monitoring center 9 mainly monitors whether the processing at the combined processing facility 8 is appropriate and manages the processing contents of the recycling performed at the combined processing facility 8, and the contents and management of the processing performed at the combined processing facility 8 This is a facility that provides information to the local residents 11 through the Internet regarding the content of the center and the surrounding environment monitoring of each center. Establishing a system that recycles the waste discharged from the local residents 11 requires securing a certain amount of waste necessary for the recycling process. In order to perform a combined process and a subsequent recycling process by collecting them in one place, it is necessary that at least the facility is functionally operable. For this reason, to realize the system of the present invention, it is considered appropriate to construct a population of about 1 million as one unit.

  In FIG. 1, it is desirable that the waste discharged by the local residents be separated at least into combustible waste, organic resource waste, and non-burnable waste at this stage if possible. In any case, the waste discharged by the local residents 11 is collected at the relay station 2 and is carried from the relay station 2 to the nearest cargo station 4 by trucks (packer cars) 3a to 3e. The waste carried to each cargo station 4, 4 is collected in the stock yard 6 by the railway 5. The waste collected in the stockyard 6 is sorted according to the type of waste and sent to the combined treatment facility 8, and the power center 8 a and the organic material recycling center in the combined treatment facility 8 according to the type of waste. 8b, distributed to the cleanup processing center 8c, processed at each center, and recycled as a recycled material M such as electric power, gas, metal material, building material, feed, fertilizer, etc. It is sold to local residents for a fee, but it can of course be sold outside the region.

The general information management center 7 collects information on each of the relay bases 2, 2..., The freight stations 4, 4..., The stock yard 6, the complex processing facility 8, and the product warehouse 10. In addition to measuring and calculating the amount of CO ₂ generated in the city and providing the data to each facility to manage the operation of the facility, through its own website, CO ₂ emissions to local residents 11 who are CO ₂ emitters Publish data as guideline information necessary to control

The point which performs the control management of the CO ₂ emission amount in the optimization area 1 of the above 1 million people will be described below. FIG. 2 is a graph modeling the concept of CO ₂ emission management in the present invention. First, the annual final target value P2 of the CO ₂ emission amount discharged in one year is set. An example of a method for setting the annual final target value P2 is, for example, a value obtained by multiplying a CO ₂ emission per capita by a certain ratio for each process and each waste type. The setting method can be considered.

According to the environmental white paper (fiscal 2002), CO ₂ emissions nationwide are about 1.25 billion tons. Dividing this by the population of 127 million people means that about 9.79 tons / year of CO ₂ is emitted per capita. From this value, the optimized area 1 of 1 million people emits 9.79 x 1 million people = 9.79 million tons / year of CO _2. And

However, the optimized area 1 of 1 million people referred to in the present invention is not an area that is closed from the self-sufficient outside world, but it is not just living by reusing waste generated in the area as a resource. Absent. Since the CO ₂ is generated along with the transportation and processing of the material supplied from outside the region, and it is affected by other regions, the above numerical value cannot be used as the target value as it is. Naturally, the target value should be a value obtained by setting a certain reduction target at a level that can be contributed by this system (estimated from the past results), and multiplying it by a constant to reduce the above value. These reduction target values in the optimal area of 1 million people differ depending on the characteristics of the area (contents of self-sufficiency and differences in rates), but the individual optimal areas of 1 million people cooperate with each other. Aiming for an optimal region (content of self-sufficiency and an increase in rate), and ultimately the optimal earth.

Next, in the present invention, in order to always manage the CO ₂ emission amount, a target value for each elapsed date and time is set. The target start point P1 and the annual final target value P2 are connected by a line, and the numerical value on the target value L1 is set as the target value for each elapsed date and time. The actual value L2 is an actual CO ₂ emission amount and is for comparison with the target value L1. The data of the actual value L2 is disclosed on the homepage of the waste information center 7 as guideline information together with the target value L1. Provide to local residents 11. When the difference from the target value L1 is large, the local residents are encouraged to reduce the volume of waste. The predicted value L3 is a predicted value of CO ₂ emission, and the predicted value is calculated using a statistical method based on the data of the actual value L2 that has occurred.

Next, data for performing the above management will be described.
FIG. 3 is a configuration diagram of files for realizing the system of the present invention in the optimization area 1 of 1 million people. In the following description, items in “” are names of items constituting the file.

In the waste transport file 13a, in addition to these, “ It has the item of “collection transportation distance”. This information is recorded in the personal computers 13 of the cargo stations 4, 4,. When the railway is not used for transporting waste, the waste transport file 13a is managed at the relay station 2, the stock yard 6, or the like.

  The waste acceptance file 14a records the state of acceptance of waste when it is transported to the treatment plant. It consists of the items of “Waste type”, “Amount (kg)”, “Treatment fee”, and “Acceptance of waste”. This information is recorded on the personal computer 14 in the stockyard 6.

About the structure of these computers, since a general thing is used, illustration is abbreviate | omitted.

  FIG. 4 is a flowchart showing the flow of the recycling system of the present invention. Details will be described below with reference to the drawings. At the same time, the relationship between each facility in FIG. 1 and each file in FIG. 3 will be described.

(1) Step 1 Annual Final Target Value Setting First, the general information management center 7 sets an annual final target value for CO ₂ emissions. An example of how to set the target value has been shown earlier (see paragraph 0023). The target value is set for each process such as collection and transportation, waste disposal, recycling, product processing, and the set value is entered in the item “annual target value” of the information provision and information notification file 16b. An item of "discharge process", collection and transport is CO ₂ emissions generated by transport track, processing, a complex processing facility 8, when processing waste, a CO ₂ emission amount generated, Recycling is the amount of CO ₂ emissions that are generated when recycled products (materials) are generated at the combined treatment facility 8. Product processing is commercializing the recycled products (materials) into more specific products. This is the amount of CO ₂ emissions generated until

(2) Step 2 Discharge of waste Next, waste is discharged from the local resident 11 who is a waste discharger to the nearest relay station 2.
(3) Step 3 Creation of Waste Discharge File Data Each relay base 2 records the information on the discharged waste in the waste discharge file 12a. The “type of waste” in the waste discharge file 12a is roughly classified as resource waste, combustible waste, non-burnable waste, and bulky waste when the waste is discharged from the discharger. In order to use it effectively in the system, it is further separated into a: unsorted waste, b: recycled waste, c: power generation waste, d: organic resource waste, e: non-burnable waste. Depending on the order of discharge, the items entering a to e may be switched.

  Among the above-mentioned wastes, waste that is difficult to recycle in existing industries and that can be completely processed is high in heat, for example, high-calorie paper waste, wood waste, waste oil, waste that does not contain harmful substances Plastic and plastic bottles can be separated as power generation waste. Organic waste such as animal and vegetable residues and garbage can be separated as organic waste. Organic material waste can be further divided into methane fermentation, feed waste and recyclable waste. Incombustible waste is recycled into products such as metal materials and building materials.

(4) Step 4 Collection and transportation of waste The trucks 3a to 3e collect waste from each relay base 2 and transport it to the cargo station 4. When transporting power generation waste, the truck 3a is responsible for transporting organic material waste, and the truck 3b is responsible for transporting organic material waste. When transporting waste, the truck is selected according to the type of waste.

(5) Step 5 Creation of waste transport file data The cargo station 4 records information on the waste transported from the trucks 3a to 3e in the waste transport file 13a. For example, the information recorded when truck 3a travels a distance of 20 km on December 3, 2005 and carries 50 kg of power generation waste is "type of waste" is "power generation waste" The “amount (kg)” is “50 kg”, the “collection transport distance” is “20 km”, and the generation date of the waste is “December 3, 2005”.

(6) Step 6 Acceptance of waste Each waste transported to the freight station 4 is collected from the same type of garbage transported by the packer car 3 when loaded into the railway (container) 5. ) 5 to the stockyard 6

(7) Step 7 Creation of waste acceptance file data The stock yard 6 records information on the waste carried from the railway (container) 5 in the waste acceptance file 14a. For example, it is assumed that power generation waste has been carried through step 5. The information recorded when the railway (container) 5 brought in 20000 kg of power generation waste on December 4, 2005 is “type of waste” is “power generation waste” and “amount (kg)” Is “20000 kg”, and the acceptance date “date of waste” is “December 4, 2005”. Further, the processing fee is calculated after the type of waste and the amount carried are recorded in the waste receiving file 14a.

  In this system, the processing fee for each type of waste is calculated, charged to the discharger (participating local government, etc.) and collected (not shown in the flowchart), so that the operation related to the facility is performed. . The processing fee is revenue (processing fee revenue + revenue from sales of recycled products)-expense (equipment cost + labor cost + material cost + other expenses)-reserve (business profit) = 0 It is calculated by calculating back for each type. According to one trial calculation of the 1 million people area model, power generation waste is 25,000 yen / ton, organic resource waste is 20,000 yen / ton, and unsorted waste is 30,000 yen / ton.

Here, the treatment fee for unsorted waste (mixed of power generation waste and organic resource waste) is set higher than that of power generation waste. The reason for this is that in non-sorted waste, the power efficiency obtained when processing is reduced, resulting in a decrease in power sales revenue. (In fact, non-fractionated dust unfractionated more garbage combustible waste and moisture, the power generation efficiency of about half of the power generation garbage (e.g. would be reduced to 30% → 15%), CO ₂ emissions Will also increase.

The important point for recycling is that if you put out the waste without sorting, it is just garbage that goes to incineration or landfill, but you can sort it into combustible waste (power generation waste), organic waste, resource waste, etc. Can be used effectively as a resource. Therefore, it is important for local residents to set a high processing fee for unsorted garbage (a mixture of garbage, paper, plastic, etc.) and to make a significant difference in the processing fee from the sorted waste. It will give the necessary guidelines for the practice of actions necessary to suppress CO ₂ generation. Proactive practice of waste separation by local residents promotes the separation and discharge of waste in the area of 1 million people, reduces the amount of waste to be incinerated, and promotes recycling (through waste power generation, methane fermentation, etc.) As a result, CO ₂ emission reduction of the whole area of 1 million people can be achieved.

  As a method of realizing, when collecting garbage, it is collected separately into unsorted garbage and sorted garbage, and their weights are measured, and the disposal unit price for each kind of garbage is applied to charge the waste source. Therefore, waste that has not been separated (mixed with garbage, paper, plastic, etc.) will be set at a high processing fee, and in order to avoid this burden, sorted discharge is promoted and incinerated. It contributes to the reduction of waste. If separation cannot be performed sufficiently, it is reasonable for the beneficiary to bear the corresponding burden.

  As a method for discriminating between unsorted garbage and sorted garbage when collecting, a method of visually identifying or applying a portable infrared sensor and measuring the amount and ratio of organic matter (garbage) can be considered.

Waste is sent to different treatment plants depending on the type.
(8) Step 8 Incineration processing Unsorted waste cannot be recycled, so it must be incinerated, and even if it generates power by incineration, the power generation efficiency is poor and CO ₂ emissions increase. By the way, power generation waste separated as power generation efficiency is about 30% efficiency, while unsorted waste is power generation efficiency of 15% or less.
Therefore, unsorted waste is sent to the combined treatment facility 8 and incinerated.

(9) Step 9 Recycling route Recycled garbage is empty cans, empty bottles, and newspapers, and is sent to a normal recycling route (an existing distribution route not shown).

(10) Step 10 Oversized garbage is disassembled and separated The oversized garbage is disassembled, and each disassembled garbage is separated according to its type.

(11) Step 11 Electrification and commercialization After generating and processing power generation waste, organic resource waste, and non-burnable waste at each facility 8a to 8c of the combined treatment facility 8, the generated waste is converted into electric power (can be sold), organic Recyclable waste is commercialized as feed, ethanol, ammonia, and phosphorus, and non-burnable waste is commercialized as metal and building materials.

(12) Step 12 Processing and Recycling Information File Data Creation Each processing site 8a to 8c records waste processing information in the processing and recycling (plant operation) information file 15a. For example, it is assumed that 20000 kg of power generation waste having undergone steps 5 and 7 is processed at the power center 8a on December 5, 2005. At this time, the information recorded in the processing / recycling (plant operation) information file 15a is that “type of waste” is “power generation waste”, “amount (kg)” is “20000 kg”, “year” “Month / Day” is “December 5, 2005”. In addition, for example, “material used” used for waste treatment is “caustic soda 500 kg”, “fuel used” is “natural gas ³ Nm ³ ”, “power used” is “2700 kWh”, and “recycled production volume” is “1000 kg”. "Etc. are recorded.

(13) Step 13 Sales Of the products produced at each center, electric power is sold to an electric power company, and other products are stored in a product warehouse and shipped according to the request of the orderer.

(14) Step 14 Creation of Product Sales Information File Data When the product factory 10 receives an order for a product from the orderer, the product factory 10 records the received “product type” and “order quantity” in the product sales information file 17a. . If there is a stock of the product in the product factory 10, the product is immediately shipped, and the “sales amount” and the “date of shipment” are recorded in the product sales information file 17a.

(15) Step 15 Calculate the CO ₂ emission results The general information management center 7 calculates the CO ₂ generation amount for each collection, transportation, processing, recycling, and product processing based on the data transmitted from each facility. To do. Also, the amount of CO ₂ generated for each type of waste (resource waste, organic material waste, non-burnable waste) is calculated. The CO ₂ emission estimation program is calculated based on the LCA (Life Cycle Assessment) method as a calculation method, for example, based on the LGA table provided by the Environmental Information Technology Center. “SUPPORT” (manufactured by NEC Factory Engineering), “LCA SLIM” (manufactured by Fujitsu FP Corporation) and the like are commercially available.

The outline of the calculation standard for CO ₂ emission is shown below.
Railway transport ton · km per, emissions of CO ₂ is 0.02kg,
Automobile transport ton · km per, emissions of CO ₂ is 0.35kg,
The amount of CO ₂ emitted per 1 kW of power generation is 0.44 kg,
Gas fuel consumption 1 m ³ per CO ₂ emissions are 2.11 kg,
Per industrial water 1m ^3, emissions of CO ₂ is 0.11kg,
CO ₂ emissions per kg of material consumption are 1-2 kg
It is said that.

First, calculation of the CO ₂ generation amount for each recycling process including collection and transportation and product processing will be described. As a method of calculating the amount of CO ₂ generated during collection and transportation,
1. A method of calculating CO ₂ ton emissions from vehicle travel distance and travel weight;
2. Although a method for calculating the CO ₂ emission amount from the fuel used in the vehicle is conceivable, in the embodiment, since there is data of “collection transport distance” in the waste transport file 13a, the above-mentioned 1. This method is used. Of course, the item “fuel used in vehicle” is provided in the waste transport file 13a and The method may be used.

The calculation is performed when data is sent from each facility, and the calculation result is recorded in the “CO ₂ generation amount” of the collection and transportation line in the discharge process of the CO ₂ emission file 16a. determine the cumulative value of the month, or determine the cumulative value of one year at the time of one year has elapsed, this is recorded in the "cumulative value" line of the collection and transportation of CO ₂ emissions file 16a.

Processing, as the calculation method of the CO ₂ emissions for the product processing,
1. The sensor always detects the CO ₂ concentration (integrated value).
2. Calculate CO ₂ emissions from materials used, fuel, and electricity.
There is a method. In the embodiment, the processing / recycling (plant operation) information file 15a includes data on “used material”, “used fuel”, and “used electric power”. This method is used. Alternatively, the CO ₂ concentration constantly detected by the environmental monitoring system is provided as data to the general information management center 7. The method may be used.

For example, CO ₂ emissions when power is produced are converted to CO ₂ (Kg) by converting the amount of materials (kg), auxiliary fuel m ³ , water m ³ , and power kWh used per kWh. Is calculated as the sum of In addition, CO ₂ emissions when building materials and metals are produced are converted to CO ₂ (Kg) in the same way as the amount of materials (kg), auxiliary fuel m ³ , water m ³ , and power used kWh per kilogram. It is calculated by adding up the converted values. CO ₂ emissions when producing feed, ethanol, ammonia, and phosphorus are converted to CO ₂ (Kg) by converting the amount of materials (kg), auxiliary fuel m ³ , water m ³ , and power kWh used per kWh, Calculated as the sum of the converted values. The calculation method is basically the same except that the materials and energy used are different for each process.

The calculation is performed when data is sent from each facility, and the calculation result is recorded in the “CO ₂ generation amount” of the processing or product processing line in the discharge process of the CO ₂ emission file 16a, and one month has passed. Sometimes the cumulative value for each emission process for one month is obtained, or the cumulative value for each emission process for one year is obtained when one year has passed, and this is accumulated in the line of the CO ₂ emission file 16a processing or product processing line. Record the value.

Here, for each type of waste, the CO ₂ emissions generated from each process through which they pass are integrated.
The calculation is performed when data is sent from each facility, and the calculation result data is recorded in the “CO ₂ generation amount” of the information providing and information notification file 16b, and the type of waste for one month when one month passes. The integrated value for each type is obtained, or the integrated value for each type of waste for one year is obtained when one year has elapsed, and this is recorded in the “integrated value” for each type of waste in the information providing and information notification file 16b. .

(16) Step 16 Prediction of CO ₂ Emissions The personal computer 16 of the general information management center 7 has a CO ₂ emission estimation program, and by using this program, CO for each emission process or waste type is used. ₂ Calculate the predicted value of emissions.

The amount of emissions is calculated from the amount of CO ₂ emissions actually generated, and how much CO ₂ is to be emitted next. A statistical prediction method is used as a means of calculation. The predicted CO ₂ emission value for each emission process is recorded in the “annual predicted value” in the CO ₂ emission file 16a, and the predicted CO ₂ emission value for each waste is provided in the “annual predicted value” in the information provision and information notification file 16b. To be recorded. In the example of FIG. 3, the prediction item in the CO ₂ emission file 16 a, the information provision and information notification file 16 b is “annual prediction value”, but of course, an item such as “monthly prediction value” may be provided. good. The target value is the so-called “total target value”, and the one corresponding to the “total target value” is the “total predicted value”, which is the cumulative and totalized CO ₂ emission predicted value for each process. .

(17) Step 17 Creation of CO ₂ Emission File Data The general information management center 7 uses the data transmitted from each facility to (CO ₂ ) emission process, “fuel”, “electric power consumption”, CO _2. Record the date of emission _{2 in} the CO ₂ emission file 16a of the General Information Management Center.

(18) Step 18 Information provision and information notification file data creation The general information management center 7 creates a data for each type of waste based on the data transmitted from each facility and the data of the created CO ₂ emission file 16a. "types of waste", CO ₂ "date" of the discharge, "CO ₂ emissions" the advertisement recorded in the information notification file 16b. Further, the “necessity of emission control” is recorded in the information provision / information notification file 16b. The data of the information provision / information notification file 16b is disclosed to the local residents 11 through the homepage.

(19) Steps 19 and 20 Information Disclosure The general information management center 7 compares the calculated actual CO ₂ emission amount with the target value, and the calculated actual CO ₂ emission amount is within an allowable range of the predetermined target value. If it exceeds, “exceed” is instructed. On the other hand, when the calculated actual CO ₂ emission amount is equal to or less than the target value, “normal” is instructed.

(20) Step 21 Emission control for each waste type is notified to the discharger When “excess” is instructed, the General Information Management Center 7 provides “Guide to Emission Suppression” in the information provision and information notification file 16b as guideline information. The target value that has been set for each property and each emission factor (for each type of waste and each processing step) is notified to the local resident 11 on the Internet homepage. When “normal” is instructed, “target achievement” is notified to the local resident 11. Note that the guideline information includes billing information necessary for practicing actions necessary for suppressing the generation of CO _{2 for} local residents. In other words, the billing information includes contents for notifying that the processing fee will be reduced if the local resident sorts and discharges the garbage according to the purpose of recycling processing according to the properties. In this embodiment, charging is applied uniformly to all the local residents belonging to the optimized area 1 of 1 million people in the present invention, but ideally, the local residents belonging to an area belonging to a certain area are configured. Ideally, it should be applied individually to each inhabitant or business.

  The general information management center 7 releases information to the local residents 11 at regular intervals. When it is time to report, the processing from step 15 to step 21 is performed. Further, after one year has passed, the process returns to step 1 to perform the process of setting the annual final target value.

Notification of "necessity of emissions" is CO ₂ emissions by the running of the vehicle is calculated by the method of LCA, CO ₂ emissions by power used, along with information such as the emissions of CO ₂ by gas used, The target value and the guideline information are disclosed together, and the local residents 11 reduce CO ₂ emissions by referring to the disclosed guideline information and self-restraining the act that causes CO ₂ generation. The local residents 11 work together to achieve the goal. As is apparent from FIG. 2, if the actual value L2 is left as it is, it will become much larger than the target value L1 and it will be difficult to approach the target value L1.

For this reason, it is desirable to disclose target values (including actual values) and guideline information as frequently as possible. This is because the range of the target value L1 can be maintained relatively easily if the local resident 11 makes an effort at a time slightly exceeding the target value L1. If the range of the target value L1 can be achieved, it will be encouraging, and it will be possible to maintain the range of the target value L1, and other regions will follow this, and it will be difficult to make progress at the national level until now. ₂ Reduction can be realized by local efforts.

  The system of the present invention makes it easy to reduce waste, which is difficult on a global scale, by making a region with a population of 1 million people as one unit. By going, it can be expected to become a foothold for tackling environmental issues on a global scale.

It is a figure which shows the structure of the system of this invention. CO ₂ emissions in the target value, the predicted value is a diagram showing the relationship between the actual value. It is a figure which shows the detail of each file. It is a flowchart which shows the flow of the system of this invention.
