Connecting Innovation to Sustainable Development Goals (SDGs)
This research achievement not only brings great pride to the institution but also plays a crucial role in driving Thailand and the global community toward the United Nations Sustainable Development Goals (SDGs) across multiple dimensions:

SDG 9: Industry, Innovation and Infrastructure

This represents the elevation of research and industrial production technology development through innovative ultrasonic wave applications, which help enhance production efficiency, develop substitute materials, and establish a green innovation foundation for the country.

SDG 12: Responsible Consumption and Production

It addresses the concept of the Circular Economy by taking agricultural waste—which is typically disposed of by burning or left to waste—and recycling it into value-added products, thereby maximizing natural resource utilization and reducing waste from the agricultural sector.

SDG 13: Climate Action

Transforming agricultural waste into high-value products such as carboxymethyl cellulose (CMC) helps mitigate open burning in the agricultural sector, which is a major cause of fine particulate matter (PM 2.5) and greenhouse gas emissions, thereby tangibly mitigating the impacts of climate change.

This success reflects the potential of Thai researchers in creating eco-friendly innovations while elevating Thailand's agricultural sector toward stable and sustainable growth.
