Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers and companies are increasingly interested in using resource-recycled carbon in chemical substances, but there is a lack of methods to determine whether such carbon is used as a carbon raw material, necessitating a system to verify the use of resource-recycled carbon in goods.
Innovation Solution
A method is developed to determine the origin of carbon source in chemical substances by calculating the ratio of carbon-14 content rates between a standard chemical substance made from recycled carbon and the chemical substance to be identified, using liquid scintillation counting to assess the carbon-14 content rates and determining the presence of resource-recycled carbon based on a ratio of 0.5 to 2.0.

Engineering Contradiction Analysis
1Measurement precision
If carbon-14 content rate measurement is performed to determine resource-recycled carbon usage, then measurement precision is improved, but device complexity increases due to need for liquid scintillation counting apparatus and standard substance management system
Solution Approach 1:
The patent measures the carbon-14 content rate (a specific parameter) in the chemical substance and compares it to a standard substance to determine resource-recycled carbon usage. By focusing on this specific parameter and establishing a reference system, the patent achieves precise measurement without requiring overly complex analytical equipment.
Solution Approach 2:
The patent creates a standard substance (chemical substance with known resource-recycled carbon content) that serves as a reference copy for comparison. This standard substance allows for simplified measurement by providing a benchmark, eliminating the need for complex absolute quantification methods.
2Reliability
If a system is established to verify resource-recycled carbon usage in chemical substances, then reliability of environmental claims is improved, but ease of operation deteriorates due to additional verification steps required for consumers and companies
Solution Approach 1:
The patent replaces complex verification procedures with a straightforward carbon-14 content rate measurement and comparison process. This substitution of measurement methodology simplifies the verification system while maintaining reliability, making it more accessible to consumers and companies.
Solution Approach 2:
The patent creates a universal verification method that can be applied to various chemical substances containing carbon from different sources (fossil fuels, biomass, waste). This multi-functional approach allows a single measurement technique to verify resource-recycled carbon usage across diverse applications, improving ease of operation.
