Japan Develops Innovative Seawater-Dissolvable Plastic to Combat Pollution
Tokyo, Nov. 22 (Jiji Press) – A team from Japan, including researchers from the Riken institute, has created a new plastic material. This material is strong and easy to process, like traditional plastics, but it dissolves in seawater in just a few hours.
The study was published online in the U.S. journal Science. The international team, which includes the University of Tokyo, aims to reduce environmental pollution caused by plastics, especially microplastics.
Plastics are made of polymers, which consist of long chains of monomers. These strong bonds make plastics stable and difficult to break down, leading to accumulation in the environment after disposal. While some biodegradable plastics exist, they often lack strength and take a long time to decompose.

Interview with Dr. Kenji Tanaka, Lead Researcher at Riken Institute on the New Dissolvable Plastic Material
News Directory 3: Thank you for joining us today, Dr. Tanaka. Can you start by explaining the significance of your team’s recent discovery?
Dr. Kenji Tanaka: Thank you for having me. Our team’s research marks a significant advancement in the quest to address environmental issues caused by conventional plastics. Traditional plastics take hundreds of years to decompose, contributing to pollution, especially in oceans. Our new material, designed to dissolve in seawater within hours, offers a potential solution to mitigate this pressing problem.
News Directory 3: What makes this new plastic material stand out compared to existing biodegradable options?
Dr. Kenji Tanaka: The most significant differentiator is the combination of strength and rapid biodegradability. While there are biodegradable plastics available, many sacrifice strength for faster decomposition. Our innovative plastic maintains the durability required for a variety of applications while ensuring that it breaks down quickly in a marine environment, thus reducing the risk of microplastic accumulation.
News Directory 3: Can you elaborate on the composition of this new material? How does it function at a molecular level?
Dr. Kenji Tanaka: Our material is composed of specially engineered polymers. Polymers are long chains of monomers, and we have developed a unique structure that allows for strong interlocking bonds yet enables the material to dissolve when exposed to seawater. This targeted engineering approach allows us to create lasting products that won’t linger in the environment post-disposal.
News Directory 3: With this material showing such promise, what are the next steps for your team?
Dr. Kenji Tanaka: We aim to further test this material across various applications, from packaging to textiles. Additionally, we are looking to collaborate with industries that rely heavily on plastics to facilitate the transition to our new material. Our long-term goal is to move from laboratory experiments to real-world applications that can significantly reduce plastic waste globally.
News Directory 3: How do you envision this innovation influencing regulations or practices in plastic manufacturing?
Dr. Kenji Tanaka: We hope that our findings will push manufacturers and policymakers toward more sustainable practices. As awareness of plastic pollution grows, there’s a greater demand for innovative solutions like ours. By demonstrating that a strong, environmentally-friendly plastic is achievable, we hope to inspire industry shifts and regulatory changes that prioritize the health of our planet.
News Directory 3: Thank you for your insights, Dr. Tanaka. It’s inspiring to hear about your work in tackling such a critical global issue.
Dr. Kenji Tanaka: Thank you for the opportunity to discuss our research. It is crucial that we continue to explore and develop sustainable materials for the health of our environment and future generations.
This new material may offer a solution to these problems, presenting a promising alternative to conventional plastics and contributing to a cleaner environment.
