A glass bottle takes 4,000 years or more to break down in nature — effectively, it is indestructible on any human timescale. Some estimates put it at a million years.
Why does it take this long?
The good news: glass is one of the most recyclable materials that exists. It can be melted and reformed endlessly without losing quality. So while a littered bottle is nearly eternal, a recycled one becomes a new bottle again and again with almost no waste.
