The plastic industry is considered a fundamental industry that supports other industries in Thailand, such as the packaging industry, electrical and electronics, construction, automotive, and aerospace industries, all of which use plastic components. The demand for plastic usage is expected to increase in the future due to its properties that meet various usage requirements. Furthermore, bioplastic, which is an alternative to traditional petroleum-based plastics that pose issues with degradation, is gaining attention. Bioplastic has the ability to naturally decompose, which helps reduce pollution caused by plastic waste. This makes the industry more sustainable, and it is increasingly recognized worldwide. Therefore, professionals in this field should receive development in both knowledge and work competencies to enhance their potential and elevate the workforce to internationally recognized standards. This will lead to the continued development of the country's plastic industry.
