INTEC Students Pioneer Sustainable Solutions: Transforming Invasive Sargassum into Biodegradable Plastic

Students from the Instituto Tecnológico de Santo Domingo (INTEC) have recently secured a significant victory in a national innovation competition with a groundbreaking project focused on sustainable manufacturing. Their initiative, titled "Plaxa Dominicana," was recognized at the "República de Ideas" contest for its innovative approach to producing lactic acid from organic waste, specifically targeting the invasive sargassum seaweed that plagues local shores. The primary objective of this project is the synthesis of polylactic acid (PLA), a versatile biodegradable polymer designed to serve as a viable alternative to traditional petroleum-based plastics.

This student-led endeavor directly addresses a critical environmental challenge facing the Dominican Republic today. Recent estimates indicate that the nation generates approximately 88,000 tons of plastic waste every year, yet only about 25% of this volume is managed through effective waste treatment systems. By introducing a localized production method for bioplastics, the INTEC project offers a practical solution for fostering a circular economy. This alignment with United Nations Sustainable Development Goal 12—which emphasizes responsible consumption and production—highlights the project's importance on both a national and global scale.

The scientific investigations conducted at INTEC reveal that the potential of sargassum extends far beyond the creation of bioplastics. Researchers are exploring various applications for this organic material, including the development of agricultural biostimulants and the production of activated carbon. To further these efforts, INTEC scientists have established a strategic partnership with the Finnish company Origin By Ocean. By exporting sargassum samples for advanced biorefining processes, the university has solidified its role as a key player in the international landscape of scientific and technological sustainability.

The massive influx of sargassum seaweed represents a dual threat to the Dominican Republic, endangering delicate marine ecosystems and the vital tourism sector. Utilizing these invasive algae for PLA production significantly reduces the overall carbon footprint compared to conventional plastic manufacturing, as the raw materials are harvested directly from the ocean environment. Furthermore, "Plaxa Dominicana" provides a much-needed economic lifeline to coastal communities and businesses. Currently, individual hotel enterprises face staggering cleanup costs ranging from $30,000 to $70,000 per month to keep their beaches clear of the encroaching seaweed.

The "República de Ideas" competition, which served as the platform for this project's recognition, is a vital component of the "Meta RD 2036" national strategy. This ambitious roadmap aims to transform the Dominican Republic into a fully developed nation by the year 2036. The development of sargassum-based bioplastics exemplifies the kind of multifaceted innovation required to meet these goals. By simultaneously tackling pollution, managing invasive species, and supporting national development objectives, the students at INTEC are paving the way for a more resilient and sustainable future for the entire Caribbean region.
