Endless benefits for the environment
The natural raw materials for glass including sand and limestone are plentiful but now more commonly cullet (glass waste) is also added into all standard glass container manufacturing. As well as the benefits of recycling previously used glass, the cullet also uses less energy to manufacture than the raw materials. In general, amber glass will have a higher recycled content at around 45% whereas white flint glass will be at around 30%.
Glass is the most commonly collected material in domestic collections, bottle banks and the hospitality industry with an approximate 50-80% recycling rate. Even glass that ends up in landfill is inert and will not produce harmful gases as it decomposes nor will it affect marine animals if discarded in the ocean.
