Suberra: Durable Recycled Cork Slabs

After cork bark is plugged by the wine industry, it can be fashioned into a durable, high-density slab called Suberra by the folks at the Eco Supply Center in Richmond, Virginia.  They compress post-industrial recycled cork grain with a polyurethane binder to create 1-1/4″ composite slabs that are 25-1/2″ wide by 36-1/2″ long.

Cork is made from Cork Oak bark, which regenerates quickly, and is composed of suberin, a water-repellant, waxy substance. Suberra gets its name from this substance.

The material can be installed using woodworking tools and standard adhesives, according to the Eco Supply Center. Suberra may also contribute to LEED credits in the rapidly renewable, recycled content, and no-added urea formaldehyde provisions.

According to lab tests, Suberra has a Class B fire rating and has a good resistance to abrasion and stain (except for ammonia, mustard, and black shoe polish in raw, unfinished samples). Each slab weighs about 31 pounds and can be used for tables, vanities, kitchen islands, desks, countertops, and other surfaces.

Suberra sells for about $250-$300 per slab.
