Summary
This study analyzed microplastic collection technologies using bibliometric data and TRIZ trends. Magnetic technologies show the most promising development aligned with evolutionary trends.
Area of Science:
- Environmental Science
- Technology Assessment
- Innovation Studies
Background:
- Microplastic pollution necessitates effective collection technologies.
- A comprehensive comparison of existing microplastic collection technologies is lacking.
- Understanding technological evolution aids in developing superior solutions.
Purpose of the Study:
- To investigate technological trends in microplastic collection using the Theory of Inventive Problem Solving (TRIZ).
- To compare different operating principles of microplastic collection technologies through bibliometric analysis.
- To identify leading technologies and their alignment with evolutionary trends.
Main Methods:
- Patent analysis of microplastic collection technologies.
- Application of bibliometric indexes: Innovation Index, Emergence Score Index, Independent Claims Index, and Technology Cycle Time Index.
- Systematic methodology to evaluate technological behaviors against TRIZ trends.
Main Results:
- Bibliometric analysis revealed varying confirmations of TRIZ trends across different indexes.
- The 'operative zone reduction' trend was most supported, while 'technical system dematerialization' was least supported.
- Magnetic technologies were ranked highest, followed by chemical, fluid dynamics, dynamic mechanics, and static mechanics.
Conclusions:
- The development of microplastic collection technologies generally aligns with identified evolutionary trends.
- Bibliometric analysis confirms the leading position of magnetic technologies in microplastic collection.
- Further research and development should consider these evolutionary trends for optimal technology selection and innovation.
