FACTS. 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 that is recovered is made into new glass products.
Is it better for the environment to use glass or plastic?
Most people would say that plastic bottles are an environmental problem especially when they are discarded in oceans or littering tourist trails. However, they are not a problem if they are recycled or reused. It is more expensive to recycle. Glass takes twice as much energy to produce.
Is glass safe?
So in summary, glass is generally considered food-grade safe. Plastic bottles and jars, on the other hand, aren't as straight forward. Some plastic materials or colorant materials are not food-grade safe, as they can be qualified as "food additives" by the FDA but do not have the GRAS designation.
