Developing innovative products from marine biomaterial to address waste marine biomass from the jewelry industry in Phuket

Abstract

The study aims to develop innovative bio-based decorative and textile materials derived from marine natural resources to promote sustainable circular  economy practices within the luxury fashion industry. The focus is placed on investigating the issue of discarded seashells-biomass waste generated by the pearl jewelry industry in Phuket, Thailand, particularly along the Andaman coastal region. This area is a significant hub for pearl oyster farming, which provides essential raw materials for high-end jewelry production. The research explores the current conditions and environmental impacts of pearl shell waste, examines value-added transformation processes, and proposes sustainable waste management strategies. The findings reveal that pearl shells primarily consist of calcium carbonate (CaCO₃) in the aragonite form, characterized by a unique hexagonal crystal structure. This structure enables the reflection of light, resulting in a natural iridescent effect known as "pearlescence" which distinguishes it from other calcium carbonate sources. These physical and optical properties make pearl shells an ideal raw material for bio-innovative applications. The study concludes that utilizing discarded pearl shells not only reduces environmental waste but also creates potential for high-value product development, contributing to sustainable luxury design. It offers a viable approach to integrating local natural resources into eco-conscious fashion innovation through circular design principles.
