What is this innovation about?

This innovation leverages seaweed washed ashore after storms in the Baltic Sea, transforming it into sustainable insulation material. Seaweed provides excellent thermal properties, is resistant to mold and pests, offers high ecological value and is fire-resistant. Collected from beaches, this material doesn’t require extensive cultivation or processing, making it both environmentally friendly and resource-efficient​.

What’s in it for a tourism SME?

For tourism SMEs, using seaweed insulation aligns with sustainable tourism practices by offering eco-friendly alternatives to conventional insulation. This approach can enhance their appeal to eco-conscious tourists, particularly in Baltic regions where seaweed is part of the local landscape. Seaweed insulation also stores CO2 and supports energy efficiency, contributing to lower heating costs for SME facilities​.

Consider that:

While effective as insulation, seaweed may involve slightly higher initial costs (about 8% more than mineral wool). However, its durability and low maintenance requirements can result in long-term savings. Installed in the insulation layer, seaweed lasts virtually forever. It can be removed and reinstalled during renovation or demolition work, or alternatively used in the garden for composting.
