With the BalticTherm product line, we are developing an insulation material made from native seagrass as a sustainable and circularly usable alternative to conventional insulation materials.
Every year, approximately 50,000 tons of conventional insulation materials are generated as waste. These materials are incinerated, recycled at great expense or merely landfilled. In addition, up to 75,000t of seaweed is washed up on the German Baltic coast every year. Municipalities pay about 40,000 € per km of beach length for cleaning.
With BalticTherm we want to create a solution out of both problems. By processing the seaweed, we make it fit for the construction industry and offer a sustainable alternative to conventional insulation materials. It scores points above all for its high moisture resistance, resistance to vermin, its fire-retardant properties and its CO2 neutrality. In terms of price, seaweed is on a par with organic insulation materials such as jute and wood fiber, and is only half as expensive as hemp.
Furthermore, by being able to sell the insulation of heat (and sound) to the customer as a service, there is a design process to use the material multiple times and open it up to additional markets.
We shorten transport distances with our regional solution and can provide an insulation material according to DIN standards and with Blue Carbon certificate. Our solution includes an automated AI-controlled cleaning of the washed up driftwood for a sorted upgrading of the seaweed.
