Dive summary:

• Researchers at the Fraunhofer Institute for Mechanics of Materials in Halle, Germany, are exhibiting tiles made from linseed oil epoxy, various natural fibers and diatomaceous earth, and they say they are more resource-efficient than ceramic and offer design options that ceramic cannot.
• The organic tiles can be produced in shapes and colors specified by a designer and with designs.
• The tiles will work in kitchen and bathroom applications and as floor tiles, and the material reduces noise compared with ceramic, the scientists say.
