Abstract:
This research sought to (1) examine the natural capital of economic crops in the Ban Tham Sue community, Phetchaburi Province, that can be utilized post-harvest for the development of souvenir products aligned with the circular economy concept, and (2) create prototype souvenir products from agricultural waste materials to augment value creation and foster ecotourism. The research utilized a mixed-methods approach that integrated quantitative surveys with participatory action research (PAR). The sample had 340 individuals, including local community members, designers, and visitors. Research instruments including questionnaires, satisfaction assessments, and Life Cycle Assessment (LCA) for product design. The results indicated that Nam Wa banana is the most promising commercial crop owing to its abundance, substantial agricultural residue, and appropriateness for repurposing as banana sheath material without chemical treatment. The created prototypes, including shoulder bags, electronic cases, and ornamental objects, attained a high satisfaction level (mean = 4.40, SD = 0.03). The design process amalgamated indigenous knowledge with modern methodologies, conforming to eco-design principles and optimizing resource use. The study additionally suggested potential avenues, including the amalgamation of banana fibers with other indigenous fibers (toddy palm or coconut) to produce hybrid natural materials, and the application of a konjacglycerin film on the surface to enhance durability and moisture resistance. This research underscores the Ban Tham Sue communitys capacity to produce eco-friendly items from agricultural waste, serving as a paradigm for sustainable community development. The results enhance the creative economy, augment local resources, and bolster ecotourism by adhering to circular economy principles.
