Assistant Professor Dr. Ekaphong In-kuea, Lecturer in Creative Product Design Faculty of Fine Arts Suan Sunandha Rajabhat University Won the gold medal "Gold" for innovation on the 23rd Moscow International Salon of Inventions and Innovative Technologies "ARCHIMEDES" at the Russian Federation Which was held on 24-27 March 2020 with online presentations
Asst. Prof. Dr. Ekaphong said that "For this work, it is experimental research on new materials to increase the value of waste materials in the coffee industry. And the shoe industry Which this material has good tensile strength Including durable High elasticity and tear resistance Can also be molded as needed In addition, the form and aroma of coffee grounds remain. Suitable for shock absorption and can be used in various industries such as the shoe industry Flooring or interior wall decoration industry "
Asst. Prof. Dr. Ekaphong said that "Thailand is driving the BCG model development (Bio Economy, Circular Economic, Green Economy) to increase economic value in the current situation. This research is a response to the government policy that focuses on solving industrial waste problems. Through the production process that can circulate or reduce waste and can be transformed into a new product that meets the needs of consumers to increase the country's economic value The most efficient and cost effective resource for sustainable development "
"The development of this material is adding value and worthwhile use of industrial waste. The value of the coffee industry in Thailand in 2018 is up to 566 million US dollars, with consumption up to 120,000 tons per year, coffee is expected to be more than 290,000 tons per year in 2022. The processing uses the ratio of ground coffee and EVA. 90:10 mixed at 120 ° C and extrusion respectively. The results are as follows: Hardness 40 Shore E, Tensile Strength 27.83 Kg / cm, Elongation at Break 165%, Tear Strength 12.98 Kg / cm, Split Tear 3.02 Kg. / cm, Shrinkage 1.64%, Compression Set 87.09%.
