O-I Fire and Sand - How Glass Is Made

Glass packaging is made of three natural ingredients: silica sand, soda ash and limestone. The materials are mixed with recycled glass--called cullet. Cullet is the main ingredient in O-I's glass bottles and containers. Globally, our glass containers contain an average of 38 percent recycled glass. Globally, we've manufactured glass with as much as 100 percent recycled content. Together, these four ingredients: sand, soda ash, limestone, and recycled glass-make up the sustainable glass package for your favorite foods and beverages.
