Transforming Sustainability: SeaSol’s Innovative Seaweed Solution for Eco-Friendly Food Packaging

When you grab a sandwich or pizza next year, you might take home something more than just your meal—a new kind of wrapper. UConn Ph.D. candidate Yidan Zhang is leading a project to create food packaging from seaweed. She hopes this innovation will help keep our planet healthy.

Zhang heads SeaSol Technologies, which is turning seaweed into a special coating for food packaging. This coating is compostable and effective, paving the way for a greener future. The team has simplified the process from 14 complicated steps to just one, making it cheaper and more efficient.

This seaweed coating can replace the plastic currently used to line paper food wrappers. It doesn’t have an odor or alter the taste of food. Plus, it feels like regular paper, while still providing a barrier against spills.

Zhang explains, “The biorefinery process is usually complex and costly. We’ve made it simpler, which lowers the product’s cost.” This technology protects people from harmful microplastics while ensuring the packaging is biodegradable.

The team is currently testing their innovation with paper manufacturers to prove its effectiveness. Alongside Zhang, the leadership includes Mingyu Qiao, a professor at UConn, and Jon McGee, a seaweed farmer. They all contribute unique expertise to the project.

Their journey is highlighted at the Wolff New Venture Competition on October 23 in Hartford, where they will compete with four other UConn-affiliated startups for a share of $150,000 in prize money. This event not only showcases emerging businesses but also emphasizes community innovation.

Zhang, who has a rich educational background in materials science, believes in the importance of real-world applications. Qiao praises her efforts, noting how their work bridges several fields to tackle pressing issues.

The SeaSol team feels a strong sense of camaraderie, pushing each other to succeed. McGee says he notices a shift in attitudes during events; people are excited about sustainable options. “They love that we’re using seaweed instead of plastic and that it’s biodegradable,” he says.

Their involvement in the Summer Fellowship Accelerator program at CCEI provided valuable insights and mentorship. Zhang found inspiration in the diverse backgrounds of fellow participants, who offered fresh ideas that she hadn’t considered before.

If they win the competition, SeaSol plans to invest in more trials and promote their product through various events. They source all their seaweed regionally, ensuring sustainability in their production process.

McGee highlights the environmental merits of seaweed, stating it is a renewable resource that benefits marine ecosystems. This shift from plastic to seaweed packaging represents a step toward a more sustainable future.

In a world where plastic waste is a growing concern, innovations like those from SeaSol might just be the solution we need.
