Glass is sustainable from its origin to its demise. ... From abundant natural raw materials, such as sand, creating glass does not require disturbing the natural environment or causing negative feedback. Because of its fully recyclable quality, glass is a sustainable choice that is able to close the consumption loop.
Glass is superior because it is: non-porous, meaning that it won't transfer food smells. Keeps foods safe (without leaching any harmful material into them). Reduces landfill waste.
