As the world’s leading glass raw materials provider, Sibelco offers a complete portfolio of high purity quartz sands, including crystalline silica, silica flour and feldspathic fluxes, limestone, kaolin and dolomite.

Every year we source over one million tonnes of glass waste that would otherwise go to landfill. We transform this glass into one million tonnes of cullet in four streams of colour. To find out more, view our glass recycling video.

Whether your objective is colour and clarity, chemical durability or mechanical strength, manufacturing efficiency or cost control, we will find a suitable solution, offering easier access to more formulating options. Complementing our portfolio, our Technical Centre is dedicated to the development of the glass industry to meet the possible future requirements of our customers.
