Resumen
The increase in the environmental crisis associated with the high level of consumption of materials such as expanded polystyrene (EPS) and the lack of post-consumer use of this material, increasing pollution levels worldwide, has led to the search for substitute materials derived from plant species that can efficiently supply the characteristics and functions provided by those traditionally used. The analysis of patents related to plant-based materials used as substitutes for EPS seeks to determine the development trends around this issue, as well as the countries that have been generating these patents and the research approaches that have been addressed, to establish a state of the art that allows drawing a roadmap around research for the promising species Montanoa quadrangularis Sch. beep. Asteraceae, as well as the innovation that may derive from these processes, understanding these patent documents as an indicator of updated and reliable knowledge for the identification of technological trends. The methodology is based on the identification of patents through the LENS.ORG platform for the 2010-2020 window, as well as the consequent analysis of the information collected through the tech-mining method and the generation of co-occurrence matrices and technological maps that allow recognizing current development trends.
