Yes, up to 70% of the glass that is used to manufacture each bottle is recycled glass, called cullet. Read how, here

Glass preserves the taste and freshness of its contents, plus it is a healthier choice, because it’s free of BPA and other synthetic chemicals.

Additionally, it has a longer shelf life than most other forms of packaging, is less damaging to the environment during the manufacturing process, is 100% recyclable, and let’s just be honest here… it simply looks better. Read more here

All manufacturing processes produce some waste material, but the glass industry produces less than most. We’re always working to find new ways to drive waste reduction at Consol Glass, and we do so through recycling banks in cities around the country, waste-wise manufacturing processes, and our involvement on the board of The Glass Recycling Company (TGRC).

Glass is made from a combination of sand, soda ash, limestone, and traces of other natural ingredients like iron and carbon. Recovered glass, otherwise known as cullet, is used too. These raw materials are stored in large silos, from where they are measured and delivered to batch mixers, and then to the furnace which is heated to approximately 1,500°C.

It takes around 24 hours for the mix to be converted into molten glass before it is sent to the refiner area to be cooled. After that, it is sent to the bottle-making machines, where different processes and moulds are used to produce different glass products.

Consol has invested an estimated R240 million in equipment and cullet processing plants, to facilitate the glass recycling process as part of our Corporate Social Investment (CSI). Our batch houses are among the most modern in the world, using leading-edge technology. All glass containers manufactured by Consol undergo multiple tests and inspections to ensure they comply with the regulations of the International Organization for Standardization, as well as our own strict quality standards.
