SMaRT Stone: cost effective, non-toxic, superior performance, recyclable

Few of us realise that much of the world’s glass cannot be easily recycled. In Australia, we recycle only 42% of our glass bottles; the rest end up in landfill. Even though most of us sort out our household waste into the different recycling bins our beer bottles, for example, may be rejected further along the chain. This is likely because they are coloured glass, so would taint an entire batch of otherwise clear glass for reuse. Many other glass types cannot be recycled at all using conventional processes. Laminated glass, used for windscreens and as safety glass for construction and other applications, and tempered glass used for cookware and other functions that demand heat resistance and durability, are not accepted by recyclers. The result is a massive global glut of waste glass, and higher and higher costs to dispose of it in landfill. Glass, however, contains about 70% silica, which is the same material that makes up quartz, a very popular quarried stone used in making attractive kitchen bench tops, bathroom vanity tops, flooring and other building materials. The idea behind SMaRT Stone was to turn waste glass into something just as beautiful and as functional as the various quartz engineered stone products on the market.

In conventional glass recycling, even 15 grams of a different type of glass can cause defects in an entire batch of recycled products. SMaRT stone, however, can be made with mixed batches of many kinds of rejected glasses. This ground glass waste is then mixed with a propriety polymer resin invented at the SMaRT Centre (that is non-toxic and causes no off gassing). The mixture is then processed as relatively low temperatures and hot pressed to form the desired product. Numerous finishes and looks can be achieved, including a marble like finish. Glass chips and colour can also be added. The end products are similar to Caesarstone but can be produced at a fraction of the cost, while cleaning up waste.
