Would you switch to household products using dissolvable seaweed-based film instead of traditional plastic?
Dirigo Sea Farm launched in late 2023, creating a water-dissolvable bioplastic film made from kelp and food-grade ingredients. The Portland-based startup currently supplies the material for use in dissolvable fertilizer sheets sold by Modern Sprout.
Why it matters
The development seeks to reduce reliance on conventional plastic packaging that contributes to microplastic exposure in the body. By leveraging kelp, researchers are exploring sustainable alternatives for both household products and potential future medical applications.
Dirigo Sea Farm has successfully manufactured nearly 20,000 square feet of its kelp-based, water-soluble film. The effectiveness and durability of these materials remain under investigation as the team researches additional microalgae species for potential use.
The players
Dirigo Sea Farm
A Maine-based startup focused on developing kelp-derived, water-soluble bioplastics.
Modern Sprout
A Chicago-based brand that incorporates dissolvable, plant-based materials into its gardening and fertilizer products.
The details
The material is created by combining dried kelp compounds with various food-grade substances to form a polymer-like structure. This mixture is processed into rolls at a Midwest factory before being utilized for products like fertilizer sheets. The team is now testing different microalgae species in tanks to create new inputs that could eventually support the production process.

Health Landscape
This development follows a trend of innovation aimed at mitigating the health risks associated with environmental microplastics. It marks a shift in material science toward biodegradable solutions that align with a growing public focus on limiting synthetic plastic exposure.
Readers interested in reducing their household plastic footprint can watch for consumer goods that utilize these water-soluble, kelp-based films. Any questions about the safety or degradation of specific packaging materials are worth discussing with a health professional during routine checkups.
The takeaway
The move toward kelp-based bioplastics illustrates a broader effort to reduce environmental plastic reliance. Keep an eye on labels for sustainable, dissolvable materials as a practical way to minimize plastic contact in your daily home routine.
