Coating’s new flame

Sustainability

They really can do everything: algae.

We’ve seen them as plastic alternatives, vegan shrimp, even as a new kind of burger.

Now comes an ecological fire retardant made from seaweed. As part of a recent competition, two students at Waterloo University, Canada, set about trying to extract biopolymers from algae.

The biopolymers’ natural fire-resistant properties were strengthened by the addition of nanoparticles, creating a protective agent that is non-toxic and safe for humans and the environment.

The agent can be sprayed or dipped on textiles and materials. And we’re hearing it will soon be available in powder form.

Our ears are burning.
