In the commercial production process of virgin cold-pressed coconut oil, a significant issue arises from the large amount of coconut residue waste generated daily. In particular, a single large-scale industrial factory produces approximately 80,000 – 90,000 kilograms of grated white coconut residue annually from oil extraction. A survey of coconut oil processing factories in Prachuap Khiri Khan province and nearby areas revealed that the processing of coconut milk and coconut oil generates no less than 20,000 tons of coconut residue per year. This substantial amount of waste poses a severe environmental challenge in terms of disposal and management within the industry.
In response to this issue, Ms.Jiratchaya Boribat and Mr.Kamon Thongchum, students from the Applied Home Economics Program, Faculty of Home Economics Technology, Rajamangala University of Technology Phra Nakhon, collaborated to add value to the leftover grated coconut residue. They developed a unique formula for sculpting dough made from coconut residue, transforming it into artificial flowers and other decorative items for commercial use. This innovative dough serves as a cost-effective alternative to expensive ready-made sculpting dough, making it ideal for crafting souvenirs, miniature products, and artificial flowers. The project is conducted under the guidance of Associate Professor Piyathida Sihawattanakul.
Mr.Kamon Thongchum explored using dried and finely ground coconut residue as a key ingredient in sculpting dough for artificial flowers. The study tested four substitution levels (11.50%, 23.00%, 34.50%, and 46.00%) and found that the optimal formula contained 23.00% coconut residue. This formula produced smooth, elastic dough with durable, flexible petals. Chemical and physical tests confirmed good moisture content (40.23%) and elasticity (7.10 mm), with color tones leaning towards green and blue.
Ms.Jiratchaya Boribat developed artificial flowers using coconut residue-based sculpting dough, which costs only 65 THB per 250g, significantly cheaper than commercial clay (270 THB). A survey of 100 respondents in Bangkok highlighted high satisfaction with the product’s beauty, eco-friendliness, and commercial viability. Online sales were the preferred distribution channel, with potential for expansion to craft stores, souvenir shops, and OTOP recognition.
Craft experts suggested further studies on the shelf life and odor reduction of coconut residue sculpting dough to enhance its quality. The research team plans to refine the product and expand its application to Thai traditional dance accessories, such as ornamental headdresses, crowns, and decorative jewelry, to increase its value.
