How the seawater-to-plastic process works
The new technology was developed by the Shenzhen Institutes of Advanced Technology (SIAT) under the Chinese Academy of Sciences. The process begins by capturing carbon dioxide directly from seawater. The captured carbon is transformed into formic acid, which becomes the foundation for producing several key bioplastic monomers such as succinic acid and lactic acid.
These monomers are then synthesized into fully biodegradable plastics, including polybutylene succinate and polylactic acid. These materials are already widely recognized in the sustainable materials industry for their low environmental impact and ability to decompose naturally. Early prototypes like biodegradable straws have already been produced, demonstrating the technology’s readiness for real-world applications. Seawater to biodegradable plastic technology
This entire operation forms what SIAT researchers call an artificial ocean carbon cycle system, representing a complete chain from seawater collection to chemical output to final biodegradable products. It is a significant technological proof of concept with wide-reaching implications.
Why this innovation matters
The debut of seawater to biodegradable plastic technology signals a turning point for several industries facing increasing pressure to reduce carbon emissions. The potential applications extend far beyond consumer goods. The same carbon conversion pathways could support new developments in marine bio-manufacturing, biofuels, pharmaceutical chemistry, and high-value chemical production.
Because the system relies on the ocean’s abundant dissolved carbon, it offers a scalable, sustainable feedstock that does not compete with farmland or freshwater resources. This positions it as an attractive alternative in global green-tech efforts.
CHTF: a major hub for global high-tech innovation
The China Hi-Tech Fair has earned a strong reputation as one of the most influential innovation platforms in Asia. Backed by local and national government support, the event hosts more than 5,000 technologies, products and research breakthroughs each year.
The 2024 fair occupies over 400,000 square meters at the Shenzhen World Exhibition & Convention Center and includes 5,000+ enterprises and organizations from more than 100 countries. Its 22 high-tech exhibition zones cover artificial intelligence, semiconductors, robotics, consumer electronics, aerospace and numerous emerging fields aligned with China’s innovation priorities.
This year’s fair emphasizes global technology exchange and highlights Shenzhen’s growing ecosystem of “20+8” industrial clusters. It serves as a catalyst for major advancements, accelerating the commercialization of high-tech solutions across industrial sectors.
New zones promote global cooperation and regional innovation
For the first time, CHTF introduced a Regional Economic and Technological Innovation Achievements Zone, showcasing breakthroughs from across China. These include clean energy technologies from western regions and digital economy innovations from the southeast.
The fair also expanded its international footprint with the International Friendly Cities Technology Exhibition Area and the Belt and Road International Cooperation Zone. These areas welcome delegations and companies from Asia, Europe and the Americas, all promoting stronger collaboration in scientific research, industrial partnerships and technology commercialization.
Countries such as Germany, Russia, Canada, Brazil and Argentina feature prominently, presenting advanced products and seeking new cooperative opportunities. Seawater to biodegradable plastic technology
