Glass that has been painted, colored, or has foiling on it cannot be recycled. This is because the decorative features are not recyclable when mixed with other glass. Once the glass gets to the plant, it is melted down for other purposes.
Amber/Brown Glass Around 31 percent of all glass produced is amber or brown in color. To create it, a small amount of sulfur, nickel and carbon is added to clear glass. Brown or amber glass bottles are often used for bottling beer. This type of glass can be recycled.
