These tiles are created from 100% recycled glass. The recycled pebbles are collected from the usual and, at times unusual, sources. The point is that these pebbles are not a manufactured product. Like the bottles you collect and recycle at home, even huge volumes of glass must be collected, shipped and stored before it can be processed into a clean, refined product. Sometimes supplies are limited or seasonal-that’s the nature of the business. But with recycled glass, it means new colors are also coming along all the time; trouble is, they’re sometimes leaving just as fast.
