CO2 Emission Calculation for Products Using Recycled Raw Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for calculating CO2 emission amounts during product production inaccurately account for recycled raw materials, as they rely solely on the reported values from suppliers, failing to consider the distinct emission profiles of recycled products.
Innovation Solution
A management apparatus and method that calculates CO2 emission amounts by distinguishing between regular and recycled raw materials, using specific emission values per unit weight for each, and accounting for the energy required in the recycling process of recycled materials, allowing for accurate reflection of CO2 emissions in the product's overall emission calculation.

Engineering Contradiction Analysis
1Ease of operation
If the CO2 emission amount of regular raw material reported from the supplier is used to calculate the CO2 emission amount of the product, then the calculation is simple, but the CO2 emission amount of the product cannot be appropriately calculated when recycled products are included as raw materials
Solution Approach 1:
The patent segments the raw materials into two distinct categories: regular raw materials and recycled raw materials. By creating separate data fields and calculation paths for each type, the system accurately tracks the CO2 emission amounts for both categories independently, then aggregates them for the total product emission amount. This segmentation resolves the contradiction by maintaining calculation simplicity through structured data organization while achieving measurement precision through type-specific emission factors.
Solution Approach 2:
The patent applies local quality by assigning different CO2 emission amount characteristics to different parts of the raw material data structure. Specifically, it introduces a distinction flag that marks whether a raw material is recycled or regular, allowing the system to apply appropriate emission factors locally to each material type. This enables accurate calculation of product CO2 emissions by treating recycled and regular materials differently where necessary, while maintaining overall calculation efficiency.
2Measurement precision
If the CO2 emission amount of recycled raw material is calculated based on energy required for recycling, then the accuracy of product CO2 emission calculation is improved, but the complexity of the calculation process increases
Solution Approach 1:
The patent implements self-service by enabling the system to automatically calculate the CO2 emission amount for recycled raw materials based on the energy consumption data of the recycling process. The calculation unit autonomously retrieves energy consumption information, applies the appropriate conversion factors, and computes the emission amounts without requiring manual intervention or complex external systems. This resolves the contradiction by achieving measurement precision through automated calculation while keeping the system complexity manageable through self-contained functionality.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the CO2 emission amount parameter based on the type of raw material and the energy consumption of the recycling process. For recycled materials, the system calculates the emission amount using energy consumption data as a variable parameter, whereas for regular materials, it uses fixed reported values. This flexible parameter approach improves accuracy while maintaining calculation simplicity through conditional logic rather than complex structural changes.

AI summary
A management method for managing a CO2 emission amount to be emitted by producing a product, includes: reading out a first CO2 emission amount that is a CO2 emission amount per unit weight of a first raw material and a second CO2 emission amount that is a CO2 emission amount per unit weight of a second raw material; and calculating the CO2 emission amount of the product based on a CO2 emission amount to be calculated from the first CO2 emission amount and from a weight of the first raw material used to produce the product, and a CO2 emission amount to be calculated from the second CO2 emission amount and from a weight of the second raw material used to produce the product.
