Glass recycling is the processing of waste glass into usable products.
Glass waste should be separated by chemical composition, and then, depending on the end use and local processing capabilities, might also have to be separated into different colors.
Many recyclers collect different colors of glass separately since glass retains its color after recycling. The most common types used for consumer containers are colorless glass, green glass, and brown or amber glass.
Glass is ideal for recycling since none of the material is degraded by normal use.
