In Hawaii, they began to make cocktail tubes from seaweed.

Loliware launched the production of seaweed cocktail straws. They replace plastic ones, keeping the coastline clean. The tubes are made like this: they dry, grind and mix the algae with a solution of natural dyes, and then give the resulting mass a shape. The technology is simple, cheap and competitive. Algae tubes are better than paper tubes: they do not get wet, they retain their shape and texture.
