Description

Technical Field

[0001] The present invention relates to the technical field of carbon footprint analysis, and in particular to a carbon footprint calculation method and system for kitchen waste disposal. Background Art

[0002] Kitchen waste refers to the garbage generated in residents' daily lives and in food processing, catering services, unit meal supply and other activities, including discarded vegetable leaves, leftovers, leftover rice, fruit peels, eggshells, tea dregs, bones (chicken bones, fish bones), etc. Its main sources are home kitchens, restaurants, hotels, canteens, markets and other industries related to food processing.

[0003] The prior art, publication number CN117422210B, discloses a carbon footprint data calculation method, device, and electronic device. The carbon footprint data calculation method includes: determining the initial process information corresponding to the product to be tested during a preset life cycle; calling a preset carbon emission source determination model to process the initial process information to obtain multiple carbon emission source information; determining the carbon emission factor corresponding to each carbon emission source information; calling a preset carbon emission prediction model to process each carbon emission source information and the corresponding carbon emission factor to obtain a carbon footprint data prediction value; if the carbon footprint data prediction value exceeds a preset carbon emission threshold, determining emission reduction measures based on the initial process information to obtain a target process; after the product to be tested executes the target process, determining the actual carbon footprint data value corresponding to the product to be tested. The above method can improve the accuracy of carbon footprint data calculation.

[0004] However, for the treatment of kitchen waste, its carbon footprint is not only related to the treatment method of kitchen waste, such as biogas power generation, incineration, landfill, composting, etc., but also related to the content of various types of kitchen waste contained in the treated kitchen waste. Because different types of kitchen waste have different organic matter content, food residues and waste rich in organic matter will release more greenhouse gases such as carbon dioxide and methane during the decomposition process, resulting in a higher carbon footprint generated by the treatment process. Even if the carbon emission factors of each portion of kitchen waste with different contents are different, the carbon emission factors are also different. In addition, kitchen waste is generally mixed together during the collection, transportation and treatment process, which makes it difficult to distinguish the specific types and contents of kitchen waste. Therefore, the above-mentioned existing technologies are not applicable. How to analyze the carbon footprints of various kitchen waste treatment methods and select appropriate kitchen waste treatment methods when the carbon emission factors cannot be determined is a problem that needs to be solved. Summary of the Invention

[0005] The purpose of the present invention is to provide a method and system for calculating the carbon footprint of kitchen waste disposal to address the above-mentioned deficiencies in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for calculating the carbon footprint of kitchen waste disposal, comprising the following steps:

[0007] S1. Recycling kitchen waste according to a first set period to obtain an amount of recycled kitchen waste. For example, the first set period may be recycling every three days or once a week, where the amount of recycled kitchen waste may be expressed in weight or volume.

[0008] S2. Obtaining a method for treating kitchen waste and the number of treatment methods. In one embodiment, the treatment methods may be incineration, landfill, biogas power generation, and composting, and the number of treatment methods is equal to 4.

[0009] S3. Sampling the kitchen waste according to a second set period to obtain a test sample, and dividing the test sample into a plurality of test subsamples, wherein the test subsamples correspond one to one with the treatment method; wherein the second set period may be equal to the first set period or may not be equal to the set period. Preferably, the second set period is an integer multiple of the first set period;

[0010] S4. Use the processing method corresponding to the test subsample to process each test subsample, and collect the carbon emissions of each test subsample in real time to obtain test data, and collect historical test data. Based on the test data of each test subsample during the test, calculate the carbon emission factor and carbon emission rate of each test subsample. The test data include the amount of kitchen waste of the test subsample used in each test, and the carbon emissions at each moment in the treatment process. The test can be carried out in a relatively closed space during the test. During the test, it is ensured that the conditions for executing each treatment method in the closed space are complete, and the treated gas is discharged from the set outlet to facilitate the detection of the carbon content in the gas. For example, the carbon content in the gas is obtained by detecting the carbon dioxide content, methane content, etc. in the gas, thereby obtaining the carbon emissions, and the carbon emissions are monitored in real time to obtain the carbon emissions at each moment in the test process, thereby obtaining the carbon emission rate when each treatment method is processed to different progress.

[0011] S5. Based on the amount of recycled food waste, set the amount of food waste to be processed by each treatment method to obtain a preset treatment volume, and calculate the estimated carbon emissions of each treatment method based on the preset treatment volume and its corresponding carbon emission factor and carbon emission rate;

[0012] S6. Set a carbon emission threshold. If the sum of the carbon emissions of each treatment method is greater than the carbon emission threshold, adjust the amount of kitchen waste processed corresponding to each treatment method until the sum of the carbon emissions of each treatment method is less than or equal to the carbon emission threshold.

[0013] Furthermore, the step S1 further includes the following steps:

[0014] The recycled kitchen waste is marked to obtain a kitchen waste information label, wherein the kitchen waste information label is used to mark the collection time, collection address, amount of recycled kitchen waste, and collection object attributes of the kitchen waste, wherein the collection object attributes include residential kitchen waste and commercial and supermarket kitchen waste. Residential kitchen waste refers to kitchen waste collected from residential communities and residential buildings, and commercial and supermarket kitchen waste refers to kitchen waste collected from shopping malls, supermarkets, corporate cafeterias, and restaurants;

[0015] The kitchen waste labels and the corresponding kitchen waste are classified according to the setting method to obtain a recycled kitchen waste group corresponding to the categories of the kitchen waste classification. When the kitchen waste is classified, kitchen waste of different categories are stored separately.

[0016] Furthermore, in step S3, sampling the kitchen waste to obtain a test sample specifically includes the following steps:

[0017] Get the number of kitchen waste recycling groups;

[0018] The kitchen waste of each recycled kitchen waste group is evenly sampled to obtain multiple test samples, and then each test sample is evenly divided into multiple test sub-samples according to the number of treatment methods.

[0019] Furthermore, the S4 specifically includes the following steps:

[0020] According to different treatment methods, multiple test groups are set up to test the test sub-samples, and sensors are set up according to the needs of data collection to collect carbon emissions in real time during the treatment process of each treatment method to generate test data; the test groups can be freely set according to needs;

[0021] Based on the test data, calculate the carbon emission rate at each moment when using each treatment method to treat a set unit amount of food waste. The set unit amount can be expressed as the amount of food waste processed by a test group using a treatment method under normal treatment, depending on the treatment method. The amount of food waste processed by other test groups is expressed as multiples of the set unit amount of the corresponding treatment method.

[0022] Based on the test data, calculate the carbon emission factors of food waste treated by each treatment method;

[0023] A regression analysis is performed on the carbon emission rate at each moment of each treatment method to obtain the relationship between the carbon emission rate and the treatment time when each treatment method treats a set unit amount of kitchen waste, and a carbon emission rate calculation formula is obtained; for example, a scatter plot of the relationship between carbon emissions and time can be drawn, that is, a scatter plot with the horizontal axis as time and the vertical axis as carbon emissions is drawn, and a regression analysis is performed on the scatter plot to obtain a regression equation for the carbon emission rate and emission time.

[0024] Furthermore, the S5 includes the following steps:

[0025] Based on the amount of recycled food waste, the amount of food waste that needs to be processed for each treatment method is set to obtain the preset processing volume of each treatment method. Based on the preset processing volume and carbon emission factor of each treatment method, the corresponding carbon emissions are calculated to obtain the estimated total carbon emissions of each treatment method;

[0026] Based on the preset processing volume of each treatment method, the set unit volume, and the carbon emission rate calculation formula, the carbon emissions of each treatment method in each set time period are calculated to obtain the expected carbon emission period volume of each treatment method, where the total expected carbon emissions of each treatment method is equal to the sum of the expected carbon emission period volumes of each set time period;

[0027] The estimated carbon emissions corresponding to each treatment method are obtained through the predicted carbon emissions of each treatment method and the estimated carbon emissions period of each set time period.

[0028] Furthermore, the step S6 includes the following steps:

[0029] S6.1. Set a carbon emission threshold, which is the maximum carbon emission allowed per set time period;

[0030] S6.2. Based on the estimated carbon emissions of each treatment method, calculate the sum of the carbon emissions of each treatment method over the set duration to obtain the estimated carbon emissions for the set duration;

[0031] S6.3. If the estimated carbon emissions during the set time are greater than the carbon emission threshold, adjust the preset processing volume of each processing method and return to S6.2; if the estimated carbon emissions during the set time are less than or equal to the carbon emission threshold, output the preset processing volume of each processing method at this time and end the step.

[0032] Furthermore, the S6.2 specifically includes the following steps:

[0033] Obtain the processing cycle of each treatment method based on the test data, where the processing cycle refers to the time required to complete the processing of a set unit amount of kitchen waste using a specified treatment method;

[0034] If the processing period is longer than the set duration of the carbon emission threshold, the processing period is divided according to the set duration to obtain multiple processing time periods;

[0035] Calculate the carbon emissions of each treatment period of the treatment method to obtain the estimated carbon emissions for each treatment period;

[0036] The estimated carbon emissions for the same treatment period for each treatment method are added together to obtain the estimated carbon emissions for the set duration.

[0041] The test processing module is a closed environment provided with a designated exhaust port, which is used to arrange the conditions required by the treatment method in the closed environment and use the corresponding treatment method to treat the kitchen waste;

[0042] The carbon emission data acquisition module is used to collect the carbon content of the gas discharged by the food waste treatment module and the test treatment module, which can be collected by sensors, for example, by monitoring the carbon dioxide content in the gas through a carbon dioxide sensor to measure the carbon content, and by monitoring the methane content in the gas through a methane sensor to measure the carbon content;

In one embodiment, the site for storing the kitchen waste can be divided into areas and numbered, and kitchen waste with different kitchen waste information tags can be placed in different numbered areas, and the numbers of the numbered areas where the kitchen waste is placed are associated with the corresponding kitchen waste information tags. Kitchen waste with the same kitchen waste information tag can also be placed in multiple numbered areas to solve the problem that there is too much kitchen waste corresponding to some kitchen waste information tags and one numbered area is not enough to store it;

[0065] In one embodiment, the setting method may be to classify the food waste information tags according to the community of the recycling address.

In the above embodiment, each test sub-sample is processed using the corresponding treatment method, such as incineration, landfilling, biogas power generation, and composting of four test sub-samples in different closed spaces, and ensuring that the treatment conditions required by the closed space during the treatment process are sufficient, such as ensuring that there is sufficient oxygen supply during the composting process to promote the rapid decomposition of organic matter without producing a large amount of methane; ensuring that the temperature, pH value and reaction time during the biogas fermentation process are well controlled to increase the methane yield and reduce the release of carbon dioxide; ensuring that there is sufficient oxygen during incineration to ensure complete combustion; ensuring that there is sufficient soil for landfilling kitchen waste during landfilling;
