The use of glass as a reliable packaging option over thousands over years has persisted because glass is environmentally friendly, inexpensive to produce from natural materials, and does not leach harmful materials into the environment.
Glass has many advantages over other packaging materials. It consists of soda ask, sand, and limestone and is 100% natural. No chemicals are present in glass as there are in plastic, and at the end of its lifecycle, glass is completely recyclable.
Glass production has very low carbon emissions, and the industry is trying to get the emissions even lower. To date, of the 7.8 tonnes of carbon emissions the soft drink industry emanates, glass consists of only 2% of that total.
Leaders in the glass manufacturing industry are trying to make glass products even lighter and more attractive as a packing option. Current glass packaging is half as light as it used to be. To date, the lightest glass bottle is used by Belu mineral water. By using glass for its water, Belu (Ethical Water) will save 50,000 kg of glass per year (equivalent to 2.1 million wine bottles) and reduce its carbon emissions by 11%.
Manufacturers are attempting to limit production line waste and have implemented high-tech camera systems to detect flaws in products and virtual sampling facilities.
Moving from clear glass to green glass reduces CO2-related emissions by 20%, thanks to the higher recycled content in green glass. Studies have demonstrated that the glass color has little to no impact on consumer perception of the product.
