Glass Recycling: Creating No Additional Waste


Glass is made from all-natural sustainable raw materials. It is the preferred packaging for consumers’ concerned about their health and the environment. Consumers prefer glass packaging for preserving a product’s taste or flavor and maintaining the integrity or healthiness of foods and beverages. Glass is the only widely-used packaging material considered “GRAS” or “generally recognized as safe” by the U.S. Food and Drug Administration. It’s also 100% recyclable and can be reused endlessly with no loss in quality or purity.

Recycling glass scrap is easy, and glass containers returned for recycling help to make new glass bottles and jars. Recycling glass has big environmental pay offs. It saves raw materials, lessens demand for energy, and cuts CO2 emissions.

Environmental Facts

Glass scrap can be recycled endlessly with no loss in quality or purity.  An estimated 80% of recovered glass containers are made into new glass bottles.  In 2013, 41.3% of glass beer and soft drink bottles, 34.5% of wine and liquor bottles, and approximately 34% of all glass containers were recycled.  In some states, like California, glass bottle recycling reaches over 80%.

Unmatched Environmental Benefits

Recycling glass scrap containers provides for unmatched production efficiencies and significant environmental benefits:

Saves raw materials — over a ton of natural resources are conserved for every ton of glass recycled, including 1,300 pounds of sand, 410 pounds of soda ash, 380 pounds of limestone, and 160 pounds of feldspar.

Annually about 3 million tons of recycled glass scrap is collected by the container and fiberglass industries, which is remelted and repurposed for use in the production of new containers and fiberglass products.

It lessens the demand for energy — Energy costs drop about 2-3% for every 10% cullet used in the manufacturing process.

Cuts CO2 emissions — For every six tons of recycled container glass used, a ton of carbon dioxide, a greenhouse gas, is reduced. A relative 10% increase in cullet reduces particulates by 8%, nitrogen oxide by 4%, and sulfur oxides by 10%.

Extends furnace life — Including cullet in the manufacturing mix makes it less corrosive and lowers the melting temperature (from 2800 degrees F. to 2600 degrees F.), prolonging furnace life.

No processing by-products — Glass scrap recycling is a closed-loop system, creating no additional waste or by-products.

Safe and Light-Weight


Today’s glass containers are approximately 40% lighter than they were 30 years ago. Efforts to reduce the weight of glass containers continue throughout the industry.

Glass packaging can handle vacuum or high-pressure sealing, safeguarding against moisture and oxygen invasions. This protects food and beverages from spoilage and bacteria.

Glass containers are impermeable, air-tight, and transparent. You can see the freshness of food and beverages.

Benefits of Glass Packaging

Glass is the trusted and proven packaging for health, taste and the environment. It is also the only widely-used food packaging granted the FDA status of “GRAS” or generally recognized as safe – the highest standard.

Nontoxic and FDA Approved

Made from nontoxic raw materials—silica, sand, soda ash, limestone and up to 70% glass scrap is recycled —glass is the only packaging material certified by the U.S. Food & Drug Administration as “generally regarded as safe.”

Glass is nonporous and impermeable, so there are no interactions between glass packaging and products to affect the flavor of food and beverages. No nasty after taste—ever.

Glass has an almost zero rate of chemical interaction, ensuring that the products inside a glass bottle keep their strength, aroma, and flavor.

Glass can be specified to absorb damaging ultraviolet light, ensuring product purity and taste. In fact, glass has an inherently longer shelf life than any packaging material.

Glass does not deteriorate, corrode, stain or fade, so products inside a glass container remain as fresh as when they were bottled.



Glass is 100% recyclable and can be recycled endlessly without loss in quality or purity.

Legislation such as container deposit measures will further enhance the benefits associated with glass packaging.

80% of the glass scrap that is recovered is made into new glass products.

A glass container can go from a recycling bin to a store shelf in as little as 30 days. An estimated 80% of recovered glass scrap containers are made into new glass bottles.

Glass is nonporous and impermeable, so there are no interactions between glass packaging and products to affect the flavor of food and beverages. No nasty after taste - ever.

Glass has an almost zero rate of chemical interactions, ensuring that the products inside a glass bottle keep their strength, aroma, and flavor.

When consumers choose foods or beverages that are packaged in glass, they avoid potential risks while enjoying a number of benefits. The life-cycle of glass—from natural raw materials, to manufacturing, through closed loop recycling—sets the environmental standard for packaging. Glass is infinitely recyclable, made from all natural ingredients, and has a 400 year record of safety.
