The said matter is the greenhouse gas emission amount required until the discharged residue 3 is generated as carbide, and the greenhouse gas generally required when the residue 3 is composted, incinerated, or landfilled. This is a result of calculating the greenhouse gas reduction rate by using the recycling system of the present embodiment based on the trial calculation of the emission amount and the calculation result.

  By providing the greenhouse gas reduction rate to the emission facility 2 in this way, the emission facility 2 can know the contribution of the country to the suppression of greenhouse gas emissions when the residue 3 is reused as carbide. . In addition, the recycle count vote can be used as a kind of index for obtaining the contribution degree of the greenhouse gas emission suppression of the emission facility 2.

  Here, an example of trial calculation of greenhouse gas emissions will be described.

  The greenhouse gas emissions emitted by the recycling system in the present embodiment can be broadly classified into the emissions from the collection and transportation company and the emissions from the recycling facility.

  The amount of discharge by the collection and transportation company includes the amount of discharge due to the use of vehicle fuel when the residue 3 is transported to the recycling facility. With respect to the emission amount, it is possible to make a trial calculation using Equation 1 and Equation 2 shown below.

CO ₂ emissions = Fuel consumption x Unit calorific value coefficient x Emission coefficient
Fuel consumption = Σ (i) mileage / average fuel consumption
i = Number of cars (hereinafter the same) (Formula 1)
Emissions on CH ₄ and N ₂ O = Travel distance x Emission factor
Travel distance = Σ (i) Fuel consumption x Emission factor (Formula 2)

  On the other hand, emissions from recycling facilities include emissions from the use of electricity at carbonization facilities, emissions from use of furnace fuel, emissions from industrial wastewater treatment, and emissions from end-of-life treatment plants due to sewage discharge. Is mentioned. The amount of discharge can be estimated by the following formulas 3 to 6.

Electric fuel consumption = Electricity consumption x Emission factor (Equation 3)
Furnace fuel consumption = Fuel consumption x Unit calorific value x Emission factor (Formula 4)
Industrial wastewater discharge = BOD load x emission factor
BOD load amount = discharge amount × BOD concentration × 0.001 (Formula 5)
Emissions from sewage discharge = Sewage treatment amount x Emission factor (Equation 6)

  In general, the amount of greenhouse gas emissions required when the residue 3 is composted, incinerated, or landfilled can be estimated by the following formulas 7 to 9.

Emissions from incineration facilities = Incineration amount x Emission factor (Formula 7)
Emissions from landfill = Amount of waste (residue 3) decomposed during the calculation period (W)
× Emission factor
W = Σ (i) dry weight × decomposition rate
Dry weight = actual weight of biodegradation discharge when composting x solid content ratio
(Formula 8)
Emissions from composting facilities = decomposition amount x emission factor
Decomposition amount = Σ (i) discharged dry weight (J) × Σ (i) decomposition rate
J = Actual weight of biodegradable emissions during composting x solids content Emissions from electricity use in composting facilities = electricity consumption x emission factor
(Formula 9)

  Note that the emission coefficient is changed depending on the type of emission (residue 3), and the default value defined in advance by the country or the like is used as the emission coefficient. The unit calorific value and the BOD concentration vary depending on the performance of the carbonization processing apparatus used in the recycling facility, and information on the performance of the carbonization processing apparatus is appropriately notified from the recycling facility to the management facility.

  In addition, the basic performance of the truck and the like used by the collection carrier 11 (for example, fuel consumption, maximum load capacity, etc.) and the emission amount by the collection carrier 11 such as the travel distance from the discharge facility 2 to the recycling facility 5 are calculated. The information for this is assumed to be stored in the computer of the management facility 10 as a database. In addition, the information used to estimate the greenhouse gas emissions required for composting, incineration, and landfill processing (for example, emission factors, solid content ratios, etc.) is the default value prescribed in advance by the country. It is assumed that it is stored in advance in the computer of the management facility 10 as a database.

  Further, the information for calculating the amount of discharge by the collection and transporter 11 is reported to the recycling facility 5 by the collection and transporter 11 every time the residue 3 is transported to the recycling facility 5. Information may be notified to the management facility 10, or the collection and transportation company 11 may notify the management facility 10 directly.

And a sales company 6 that accepts and sells the activated carbide 4 and reuses it, and the residue 3 is appropriately reused as the activated carbide 4 in a recycling system that reuses the residue 3 as the activated carbide 4. The management facility 10 is newly provided to manage whether or not the residue is generated, and the management facility 10 activates the residue information such as the type and weight of the residue 3 discharged from the discharge facility 2 and the activation generated from the residue 3. Carbide information such as the type and weight of the carbide 4, carbonization processing condition information when generating the activated carbide 4, reusable information such as the reuse field for reusing the activated carbide 4 and its weight Based on the obtained information, the recycling rate of the activated carbide 4 with respect to the residue 3 and the greenhouse when the residue 3 is composted, burned, and landfilled when the residue 3 is used as the activated carbide 4 Calculate the effect gas reduction rate, determine whether or not the carbonization treatment conditions of the generated activated carbide 4 are appropriate, and obtain a recycling count vote including the recycling rate, greenhouse gas reduction rate, and judgment result The recycling count vote is generated and issued to the discharge facility 2.
