Abstract

Background While our previous research established the effectiveness of participatory design approaches in developing innovative banana fiber products in Thailand, this study addresses the critical gap between prototype development and commercial viability. Traditional craft materials like banana fiber offer potential for sustainable innovation, but their successful commercialization requires frameworks that balance cultural preservation with market demands. This research introduces the Material Transformation Dimension framework for guiding the commercial development of agricultural by-product crafts. Methods Building on our established Creative Knowledge Integration approach, we implemented the Material Transformation Dimension (MTD) framework through a seven-phase methodology: (1) material exploration based on previous prototypes, (2) community enterprise capabilities analysis, (3) promotional strategy investigation, (4) collaborative planning, (5) product and promotional material development, (6) stakeholder presentation, and (7) commercial implementation and market testing. Data was collected through field research, interviews, collaborative workshops, and market feedback sessions with the Creative Agriculture Community Enterprise Group in Nakhon Si Thammarat Province. Results The research yielded three significant outcomes: a commercially viable collection of banana fiber design products adapted from previous prototypes to suit local production capabilities while maintaining cultural authenticity; a complete brand identity system including logos and promotional materials that effectively communicate the cultural and sustainable value of the products; and a knowledge transfer framework enabling community members to independently develop and market future products. These outcomes demonstrated positive market reception signals through initial commercial testing, indicating potential for sustainable income generation for community members. Conclusions This bounded case study demonstrates how the Material Transformation Dimension framework bridges the gap between traditional craft innovation and commercial viability. By integrating design expertise with community knowledge and market awareness, the research suggests a potential model for transforming agricultural by-products into sustainable commercial enterprises. The approach not only preserves traditional craftsmanship but also creates economic opportunities that support cultural sustainability while addressing growing consumer interest in environmentally responsible products.
