Principal Component Analysis and Causal Modeling in the Valorization of Banana Pseudostems for Biodegradable Materials

Abstract

The study focused on evaluating the opinions of banana producers in Ecuador regarding the use of natural fibers from banana plant pseudostem as a sustainable alternative to produce biodegradable materials. Expert-validated surveys were conducted with 197 managers and owners of banana farms in Zone 5. The research employed a quantitative methodology for data collection. A descriptive analysis of the survey instrument items assessed the distribution and dispersion of the data, along with a correlation analysis between instrument categories. A multivariate PCA was used to condense the data and identify the principal components that explain variations in responses. A causal model based on these principal components was then created and tested for statistical fit.

The findings revealed that participants generally viewed the identified elements-initiatives and sustainability mechanisms-favorably. The research indicates that banana pseudostems could be a viable option to produce biodegradable products, addressing the growing waste problem in the banana industry.
