BottleStone is a beautiful, new green surface material made of 80% post-consumer recycled glass. BottleStone provides a green alternative to stone slabs offering the same warm aesthetics of natural stone materials.

Bottlestone also meets or exceeds all of the other heat, scratch and stain resistant characteristics of stone slabs, not to mention a wonderful array of colors. BottleStone is everything you want for an internal or external stone surface plus it's green and eligible for LEED* credits - something you just can't get from natural stone and many other surfaces.

The glass waste we use is direct from post-consumer (glass bottles), and is generated in Northern California and requires no further processing before its use in BottleStone. A beautiful product from recycled waste glass. Learn more about this truly innovative green building material.
