Description

Technical Field

[0001] This document relates to the field of computer technology, and in particular to a method and apparatus for calculating carbon emission reduction throughout the entire life cycle of recyclable packaging. Background Technology

[0002] As the global goal of carbon neutrality progresses, the express delivery and logistics industry is gradually advancing its green transformation. Recyclable packaging, due to its reusable nature, is considered an important means of emission reduction to replace single-use packaging. Although many express delivery and logistics companies have already promoted recyclable packaging on a small scale in various scenarios to reduce carbon emissions and have achieved good social and environmental benefits, large-scale research on carbon emission reduction through recyclable packaging in China has not yet been carried out. The current lack of a scientific and unified carbon emission reduction accounting method makes it difficult for companies to quantify the environmental benefits of recyclable packaging, hindering its large-scale promotion and participation in the carbon trading market.

[0003] Currently, research on carbon emission reduction through recyclable packaging in China has not been conducted on a large scale, and relevant data is relatively scarce, resulting in the public having little understanding of the emission reduction contributions of recyclable packaging. Furthermore, the calculation processes used by manufacturers that have publicly released carbon emission reduction data are unclear and lack authority, posing challenges to the accuracy and reliability of carbon emission reduction accounting for recyclable packaging.

[0004] Furthermore, reusable packaging has encountered numerous problems in practical application, significantly hindering its large-scale promotion. First, the change in operational processes places a burden on frontline staff, leading to a lack of willingness to use reusable packaging. Second, the one-time purchase cost of reusable packaging is too high, and product quality is difficult to guarantee effectively. Third, there is a lack of effective information management tools; China Post has not yet established a reusable packaging operation and management system across its entire network. Fourth, the promotion of reusable packaging requires multi-party collaboration, which is difficult to coordinate. Fifth, the recycling of reusable packaging is difficult. The recycling of reusable packaging increases the workload in the delivery process, affecting delivery efficiency, resulting in low acceptance of reusable packaging among delivery personnel.

[0005] Therefore, providing a standardized method for calculating carbon emission reductions throughout the entire life cycle has become a pressing technical challenge for the industry. Summary of the Invention

[0012] The calculation module is used to calculate the carbon emissions for the baseline scenario and the project scenario using a life-cycle carbon emissions accounting method.

[0046] The basic method for carbon emission reduction accounting of recyclable packaging in this invention includes the following basic steps: Figure 2 As shown, firstly, a method for calculating the carbon emissions of packaging throughout its entire life cycle is proposed. The calculation principle is that both baseline emissions and project emissions are calculated using this method. Specifically, this includes calculating carbon emissions from raw materials, production processes, transportation processes, cyclic cleaning and disinfection processes, and waste disposal processes. Secondly, a method for calculating carbon emission reductions is proposed. Baseline and project scenarios are set. Baseline scenario: Single-use packaging is discarded after a single use, resulting in higher life-cycle emissions per use. Project scenario: Reusable packaging is used multiple times within its design life, resulting in lower life-cycle emissions per use. When calculating actual emission reductions, it should be noted that reusable packaging, through redesigning more robust and durable packaging materials and recycling them, can replace ordinary single-use packaging of the same specifications multiple times. Therefore, emission reductions for reusable packaging should be calculated based on its single use.

[0047] Carbon emission reduction calculation for reusable packaging: This embodiment of the invention calculates carbon emission reductions for four types of packaging: general reusable packaging boxes, professional reusable packaging boxes, reusable sleeves, and reusable packaging bags; and four different scenarios: general use, government use, commercial use, and community group buying. It outlines the uses and specifications of all reusable packaging. Baseline emissions: Based on the unit mass of the packaging materials provided by the supplier and the reference emission factors, the emissions from raw materials, production processes, and waste disposal processes for each type of packaging are calculated. Project emissions: Based on the unit mass of the reusable packaging materials provided by the supplier and the reference emission factors, the emissions from raw materials, production processes, transportation processes, reusable cleaning and disinfection processes, and waste disposal processes for each type of packaging are calculated.

[0104] As can be seen from the above technical solutions, the embodiments of the present invention define the boundaries and main emission types for carbon emission reduction accounting of recyclable packaging. First, the embodiments of the present invention clarify the system boundaries for carbon emission reduction accounting of recyclable packaging, which includes the entire lifecycle from raw material acquisition, manufacturing, packaging use, recycling, to final disposal. In this process, the main emission types cover a wide range, including but not limited to emissions from energy consumption, material production, and transportation. Identifying these emission types is crucial for accurately calculating the carbon footprint.

[0105] The selection of emission factors for raw materials at the product's upstream end is crucial. During the accounting process, the choice of raw materials directly impacts carbon emissions. It is necessary to scientifically assess the carbon emission factors of different raw materials (such as plastics, paper, and metals), as these factors reflect the carbon emissions per unit mass or volume from raw material acquisition to processing. Therefore, the embodiments of this invention select an appropriate carbon emission database and correctly apply these emission factors, which plays a decisive role in assessing the environmental impact of reusable packaging.

[0106] Production process emissions from typical manufacturing processes are a significant component of the carbon footprint of recyclable packaging. This invention analyzes and quantifies different manufacturing processes, collecting energy consumption and emissions data for processes such as injection molding, blow molding, and printing. By refining the production process emission data for typical manufacturing processes, it is possible to identify the emission reduction potential in the production processes of recyclable packaging suppliers and help them optimize their processes.

[0107] Additional emissions during product recycling. Recyclable packaging is designed to reduce the use of single-use packaging, thereby lowering carbon emissions. However, additional emissions, such as those from transportation and cleaning, are generated during recycling. This invention assesses the impact of these additional emissions on the overall carbon footprint and incorporates them into the carbon reduction accounting system for recyclable packaging, making the carbon footprint of recyclable packaging more complete.

[0108] Emissions from product disposal and recycling processes. After the recycling cycle of reusable packaging ends, its disposal and recycling processes also generate certain carbon emissions. To accurately calculate the carbon emissions in this stage, this invention selects suitable waste disposal factors for carbon emission calculation, aiming to obtain scientific and reasonable calculation results.

[0109] In summary, the embodiments of the present invention construct a scientific and accurate carbon emission reduction calculation model for recyclable packaging, providing a quantitative environmental benefit assessment for the promotion and application of recyclable packaging, thereby promoting the transformation of the express logistics industry towards a green and low-carbon development direction.
