[0002] Controlling greenhouse gas emissions in the field of domestic waste treatment is of great significance to environmental protection and climate change mitigation. It is also a key link in promoting the sustainable development of the waste treatment industry, improving the ecological environment and protecting public health. Accurate accounting of greenhouse gases in the field of domestic waste treatment is the basis for greenhouse gas control. At present, China's greenhouse gas accounting guidelines for domestic waste treatment mainly focus on terminal treatment and disposal processes such as incineration or landfilling of domestic waste, and lack accurate accounting methods for the collection and transportation process. Garbage collection and transportation within the community is the starting point of the entire process of domestic waste treatment. The greenhouse gas accounting methods for community garbage collection and transportation often only consider the direct or indirect emissions caused by the driving process of the collection and transportation vehicles, and do not consider the loading / unloading process of domestic waste. Studies have shown that this process is the main source of greenhouse gas emissions in the collection and transportation process within the community. Therefore, the current greenhouse gas accounting methods for community garbage collection and transportation have the problem of inaccurate accounting. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] The present application provides a method for calculating greenhouse gas emissions from different domestic waste collection and transportation routes within a community, which solves the problem of accurate calculation of greenhouse gas emissions during the waste collection and transportation process within the community, and provides a basis for the selection of optimal low-carbon collection and transportation routes and the layout of domestic waste collection points within the community.

[0034] In an exemplary embodiment, Figure 1 As shown, a method for determining a low-carbon collection and transportation route for community domestic waste is provided, comprising the following steps:

[0035] S1: Determine multiple garbage collection and transportation routes within the community's domestic garbage greenhouse gas accounting boundary; the community's domestic garbage greenhouse gas accounting boundary is the process from the collection and transportation vehicle entering the community to leaving the community.

[0036] In practical applications, the accounting boundary of greenhouse gas emissions during the collection and transportation of community domestic waste is determined. The accounting scope includes the direct or indirect greenhouse gas emissions generated by the work of the collection and transportation vehicles from the time the collection and transportation vehicles enter the community to the time they leave the community.

[0037] S2: Determine the greenhouse gas emissions of each greenhouse gas emission source in each of the garbage collection and transportation routes; the greenhouse gas emission sources include the driving process of the collection and transportation vehicle in the community, the waiting process of the collection and transportation vehicle in place, and the loading and unloading process of the collection and transportation vehicle; wherein, the greenhouse gas emissions of the collection and transportation vehicle in the driving process of the community are determined based on the mileage of the garbage collection and transportation route and the greenhouse gas emission factor of the collection and transportation vehicle during the driving process; the greenhouse gas emissions of the collection and transportation vehicle in the waiting process are determined based on the engine power of the collection and transportation vehicle when idling, the engine fuel consumption rate of the collection and transportation vehicle when idling, and the total loading and unloading time of the collection and transportation vehicle in the garbage collection and transportation route; the greenhouse gas emissions of the collection and transportation vehicle in the loading and unloading process of the garbage collection and transportation vehicle are determined based on the engine power when the collection and transportation vehicle provides kinetic energy for the loading and unloading machinery, the engine fuel consumption rate when the collection and transportation vehicle provides kinetic energy for the loading and unloading machinery, and the total loading and unloading time of the collection and transportation vehicle in the garbage collection and transportation route.

[0038] In practical applications, the identification of greenhouse gas emission sources within the accounting boundary mainly involves examining and evaluating the energy activities of the entire process of garbage collection and transportation in the community, and identifying the main emission sources as direct or indirect greenhouse gas emissions generated by collection and transportation vehicles driving in the community, collection and transportation vehicles waiting on site, and collection and transportation vehicles loading and unloading garbage.

[0039] The main sources of greenhouse gas emissions include the driving of garbage collection and transportation vehicles in the community, waiting in place, and providing kinetic energy to the loading and unloading machinery during garbage loading and unloading. The combustion of fossil fuels in fuel collection and transportation vehicles directly emits CO2, CH4 and N2O. The driving of collection and transportation vehicles in the community includes driving between garbage bins and driving at garbage collection points. The biodegradable components in domestic garbage degrade during the stay of garbage at the garbage disposal point, that is, the garbage bin, and directly emit CO2, CH4 and N2O. Indirect emissions include indirect emissions caused by the power consumption of electric collection and transportation vehicles during the collection and transportation process.

[0040] As an optional implementation method, the greenhouse gas emissions of the garbage collection and transportation vehicle during its driving process in the community are determined based on the mileage of the garbage collection and transportation route and the greenhouse gas emission factor of the garbage collection and transportation vehicle during its driving process, specifically including:

[0041] Determine the garbage collection and transportation scenario of the collection and transportation vehicle; the garbage collection and transportation scenario is the first collection and transportation scenario or the second collection and transportation scenario; the first collection and transportation scenario is that the collection and transportation vehicle drives into the community to collect and transport garbage from each delivery point; the second collection and transportation scenario is that the collection and transportation vehicle drives to the community garbage collection point to load garbage in the community.

[0042] Calculate the mileage of the garbage collection and transportation routes under the garbage collection and transportation scenarios, and obtain the greenhouse gas emission factors of the garbage collection and transportation vehicles during driving.

[0043] Based on the mileage and greenhouse gas emission factors during driving, determine the greenhouse gas emissions of the collection and transportation vehicle during driving in the community. Specifically, it includes:

[0044] Using the formula Determine the greenhouse gas emissions of the collection and transportation vehicles during their travel in the community; where E 行驶 is the greenhouse gas emissions (including CO2, CH4, N2O) of the collection and transportation vehicle during its driving in the community, kg / t; D i,l is the mileage of the i-th type of garbage collection and transportation vehicle on the l-th garbage collection and transportation route, km; is the carbon dioxide emission factor of the i-th type of collection and transportation vehicle, in milligrams of carbon dioxide per kilometer, mgCO2 / km. If the i-th type of collection and transportation vehicle consumes electricity, Ei is the electric energy consumption of the i-th model electric vehicle during driving, kwh / km; EFr is the average carbon dioxide emission factor of the regional power grid r, kgCO2 / kWh; is the CH4 emission factor of the i-th type of collection and transportation vehicle, in milligrams of methane per kilometer (mgCH4 / km); is the N2O emission factor of the i-th type of collection and transportation vehicle, in milligrams of nitrous oxide per kilometer (mgN2O / km); is the global warming potential of CH4, The global warming potential of N2O is the value recommended by the IPCC Second Assessment Report on a 100-year time scale. The GWP values ​​of CH4 and N2O converted into CO2 equivalents are 21 and 310 respectively.

[0045] D i,l The calculation method is as follows:

[0046] Scenario 1: If the garbage truck drives directly into the community to collect garbage from each garbage disposal point, the garbage collection route is the sum of the distances the truck travels from the time it enters the community to the time it drives to each garbage disposal site.

[0047]

[0048] lk Complete the routes and km for garbage trucks to collect and transport garbage bins within the community.

[0049] l n It is the distance between two adjacent delivery points on the collection and transportation route, km.

[0050]

[0051] B is the number of sites deployed in the community.

[0052] S is the cell area, m 2 .

[0053] S1 is the service area of ​​the garbage disposal site in the community, m 2 .

[0054] Scenario 2: After the garbage in the community is collected by a small vehicle, the garbage truck drives to the collection point in the community to load the garbage in the community.

[0055] D i,l =l1+l k .

[0056] l1 is the distance the garbage truck travels to the garbage collection point in the community and then drives out of the community, km.

[0057] As an optional implementation method, the greenhouse gas emissions of the collection and transportation vehicle during the waiting process are determined according to the engine power of the collection and transportation vehicle when it is idling, the engine fuel consumption rate of the collection and transportation vehicle when it is idling, and the total loading and unloading time of the collection and transportation vehicle in the garbage collection and transportation route, specifically including:

[0058] Using Formula E 等待 =P i ×T×C i ×η i ×EF i Determine the greenhouse gas emissions of the collection and transportation vehicle during the waiting process; where E 等待 is the greenhouse gas emissions of the collection and transportation vehicle during the waiting process, kg; p i is the engine power of the i-th type of collection and transportation vehicle at idle speed, W; T is the total loading and unloading time of the collection and transportation vehicle in the garbage collection and transportation route, h; C i is the density of the fuel of the i-th type of collection and transportation vehicle, kg / L; η i is the fuel consumption rate of the engine of the i-th type of collection and transportation vehicle at idle speed, g / kW·h; EF i is the carbon emission coefficient of the fuel of the i-th type of collection and transportation vehicle, kgCO2 / L.

[0059] In actual applications, the waiting time of collection vehicles on different collection routes of domestic waste in the community is mainly because when the collection vehicles run to the delivery point, they need to wait for the on-board machinery to complete the loading and unloading of the garbage bins. Therefore, the waiting time of the collection vehicles in the community is the product of the average time for loading and unloading each garbage bin and the number of garbage bins in the community. The greenhouse gas emissions can be calculated by clarifying the waiting time and the relevant parameters of the collection vehicle operation.

[0060] T=mt.

[0061] t is the average time for a collection and transportation vehicle to load and unload a trash can, seconds; m is the minimum number of trash cans in the community, pieces.

[0062]

[0063] N is the permanent population of the community, people. n is the standard coefficient for setting the trash can, people / unit.

[0064] As an optional implementation method, the greenhouse gas emissions during the garbage collection and transportation vehicle loading and unloading process are determined based on the engine power when the garbage collection and transportation vehicle provides kinetic energy for the loading and unloading machinery, the engine fuel consumption rate when the garbage collection and transportation vehicle provides kinetic energy for the loading and unloading machinery, and the total loading and unloading time of the garbage collection and transportation vehicle in the garbage collection and transportation route, specifically including:

[0065] Using Formula E 装卸 =P' i ×T×θ i ×C i ×EF i Determine the greenhouse gas emissions during the garbage collection and transportation process; E 装卸 is the greenhouse gas emissions during the garbage collection and transportation process, kg; P' i is the engine power of the i-th type of collection and transportation vehicle when providing kinetic energy to the loading and unloading machinery, W; θ i The fuel consumption rate of the engine when the i-th type of collection and transportation vehicle provides kinetic energy for the loading and unloading machinery, g / kW·h.

[0066] In actual applications, the energy required for the loading and unloading process of collection trucks on different collection routes within the community is provided by the engine of the collection truck. Therefore, in actual operations, the driver needs to step on the accelerator during idling to provide kinetic energy.

[0067] S3: Determine the total greenhouse gas emissions of each of the garbage collection and transportation routes based on the greenhouse gas emissions of each greenhouse gas emission source.

[0068] As an optional implementation method, the total amount of greenhouse gas emissions of each garbage collection and transportation route is determined according to the greenhouse gas emissions of each greenhouse gas emission source, specifically including:

[0069] Using Formula E 社区收运 =E行驶 +E 等待 +E 装卸 Determine the total amount of greenhouse gas emissions from each of the garbage collection and transportation routes; where E 社区收运 is the total greenhouse gas emissions of a garbage collection and transportation vehicle on a garbage collection and transportation route; E 行驶 E is the greenhouse gas emissions from the collection and transportation vehicles driving in the community; 等待 E is the greenhouse gas emissions during the waiting process of the collection and transportation vehicle; 装卸 Greenhouse gas emissions from the process of loading and unloading garbage collection trucks.

[0070] In practical applications, the emission factor method and mass balance method are used to establish a greenhouse gas emission accounting model for the entire process of garbage collection and transportation in the community, and the sum of direct and indirect greenhouse gas emissions of each accounting unit is calculated separately. The greenhouse gas emission accounting model is as follows:

[0071]

[0072] S4: Determine an optimal low-carbon collection and transportation route based on the total amount of greenhouse gas emissions of each of the garbage collection and transportation routes; the optimal low-carbon collection and transportation route is the garbage collection and transportation route corresponding to the minimum value of the total amount of greenhouse gas emissions.

[0073] This application provides a method for calculating greenhouse gas emissions from different collection and transportation routes for community domestic waste, and constructs a method for calculating greenhouse gas emissions from the driving process of the collection and transportation vehicle, the waiting process of the collection and transportation vehicle in the community, and the loading / unloading process of domestic waste in the community. It solves the problem of accurate calculation of greenhouse gas emissions from different collection and transportation routes for community waste, and provides a basis for the selection of the optimal low-carbon collection and transportation route.
